3.2 General information The eBick is a smart energy storage system with Li-ion cells. The whole system contains a high energy capacity. To minimize the risk of electric shock, short-circuit, explosion and/or fire, follow the relevant procedures and local guidelines, as well as the instructions that are included with the system. Only qualified personnel should perform the installation, in accordance with the applicable regulations. Systems with visible electrical connections have to be isolated from public access. For safety reasons, cover all direct connections and terminals. Carefully read, understand and apply all requirements presented in this section. 3.3 Safety instructions – Potential hazards • The area around the eBick shall be kept clear and free of combustible materials, gasoline and/or other flammable fumes, vapours and liquids. • The area defined by safety margins for the necessary supply and venting of air shall be respected. • In the event of an emergency the eBick has electrical safety cut-off elements (fuses and contactors). It is advisable to install an element that protects against overcurrent and possible short-circuiting. It is also advisable that the cut-off element can be manually operated if necessary. Remember, because this is a battery the STRING’s internal DC bus will always have a voltage. • Do not use the module if any of its parts have been immersed in water. A water damaged cell is potentially dangerous. Any attempts to use the system could cause a fire or an explosion. In such cases, contact CEGASA ENERGIA to have the battery pack inspected. • The following instructions shall always be followed: o Any air inlet or outlet within the room shall be kept clear and free of obstacles. o The floor shall be capable of bearing the weight of the STRING. o There shall be no obvious signs of wear on any STRING element. o As this is a battery, there is voltage on the +/- terminals whenever the MCP contactor is closed. www.cegasa.com www.cegasa.com Page -7- User Manual R10 – First steps –
3.5 Electrical safety • Never remove safety guards or devices that protect against live parts. • Do not reach inside the STRING or the modules, nor touch any internal component. • Do not use or handle any eBick component when accidentally wet, or with wet hands or feet. • In the event of a failure or incident, as a first step cut off the current. To help a person being electrocuted, do not touch them but immediately cut the current. If it is not possible or takes too long to cut the current, try to disengage them by means of an insulating element (wooden strip or board, rope, wooden chair ...). • Whenever a module is not installed on the STRING, make sure that the power terminals at the front are protected against accidental contact. • Make sure that the output and input connection cables are not short- circuited. • Make sure there is no short circuit between positive and negative terminals at any point. • Make sure there is always protective insulation on the output and input cables and a reliable connection. • Never use cables that are visibly damaged or that may be suspected of being damaged. • Minimise conductivity, avoiding surfaces in contact with water. Hands and clothes have to be dry. • Do not use, install or store the system under wet or damp conditions. 3.6 Mechanical safety • Due to the weight of the battery modules (> 100 kg), mechanical means have to be employed to install them. • Do not stack eBick modules more than 4 high. 3.7 User requirements In addition to personnel who work with the module, workplace users should also implement safety measure by applying the minimum provisions of RD 614/2001 on the protection of the health and safety of workers exposed to electrical risk in the workplace. Hazards related to electrical risk are specifically identified during the work process with this equipment. This does not exclude the possible existence of other risks present during handling and use, such as overexertion, posture, or other measures against health risks. Operators shall receive the necessary training, sufficient to be able to prevent and avoid any risks arising from use of the equipment. By design the equipment protects against these risks under normal operating conditions, however, it is with operations that differ from normal ones (installation, maintenance, ...) where special precautions have to be taken. Particular care should be taken when handling modules, due to their weight. Respect guidelines according to current regulations regarding ergonomics in the workplace (Royal Decree 487/1997). Use appropriate handling equipment. www.cegasa.com www.cegasa.com Page -8- User Manual R10 – First steps –
3.8 Lockout-tagout of machines and installations (LOTO) To perform operations absent of voltage (LOTO), the device must be locked and tagged to non-hazardous voltage values. The following section is based on the lockout-tagout at several points according to RD 614/2001: 1. Restrict access to the work area to prevent entry of unauthorised personnel. 2. It shall be disconnected and isolated from the supply network or the connection to the converter. 3. Once disconnected, the STRING shall be sectioned into parts with voltages below 75 VDC. 4. The terminals of these parts shall be protected by insulating caps designed for this purpose. 5. Given that the batteries are an energy storage system, it is impossible to make certain points of the system free of voltage. If there is any exposed point where the voltage cannot be eliminated, the terminals will have to be tagged, indicating the voltage value at that point. 6. Prior to conducting any work, the voltage shall be measured at the point where the work is to be done. Some points may be energised directly from the batteries. To carry this out, it is necessary to do the following: • Use only 1000V insulated tools • If terminals are exposed during the sectioning process, use 1000V rated insulating gloves. • Use a face shield during the work. • Should it be necessary to perform an operation on a battery pack, place the modules on Insulating matting. • Use insulating footwear. • To avoid possible short-circuiting, do not carry any conductive device (e.g. pens, tape measures, etc.) during the work. • Do not wear any metal, conductive or sharp-edged accessories. 3.9 Switching, measurements and checks The regulation permits operations and interventions without lockout-tagout, provided that an equivalent level of safety is guaranteed. These interventions are called switching, trials and checks. They have to be carried out by authorised personnel with protection devices and personal protective equipment appropriate for the voltages in question. It should be especially protected against short-circuits. Instructions to follow: • The operations shall only be carried by authorised, duly trained, personnel. www.cegasa.com www.cegasa.com Page -9- User Manual R10 – First steps –
• Safety apparel that covers the whole body (long sleeves) shall be used. Fireproof or flame retardant, with protection against chemicals and arc flash. • The work shall be done from a solid, stable support • If a work table is used, it shall be insulated or covered with Insulating matting. • No terminal with an electrical charge should be left uncovered. If, after removing the connections, the terminals are exposed then they have to be protected with the terminal covers supplied. • All tools shall be insulated and rated up to 1000V • Insulating gloves, at least class 0 (1000V), shall be worn until existing voltages are cut to levels below 50V DC. • Operators shall not wear or carry any metal elements or devices. • The work area shall be free of obstacles. • If necessary, when there are exposed terminals nylon slings shall be used instead of chains. • The operator shall wear a face shield or safety glasses to protect against short-circuits • Occasionally, depending on the operation, there should be an OHS assistant present. • This person should satisfy that stated in Annex IV of RD 614/2001 4 Assembly of the equipment Caution: Given that the modules are supplied with electrical charge levels necessary to maintain the chemical properties of the batteries, the entire installation process shall perform with the recommended protection equipment. Each battery module and MCP are pre-wired, pre-set and factory tested. After receiving and unpacking the system, the installer should find that each string contains: - An MCP module - Various eBick modules, these will be P or S depending on the system set-up. - A BUS termination resistor - S-BRIDGE CONNECTOR - Only for eBick-S set-ups connected in series - PROTECTIVE COVER - Only for eBick-P set-ups connected in parallel - One or more base frames with feet and wall or floor mounting plate/s - A set of fastening plates for between modules, base frame and MCP (with fasteners) - A set of KIT communications and power extenders (*) (*) Should the project have more than 4 modules, these have to be distributed in several columns. The wiring between columns will be done using these extension cables. www.cegasa.com www.cegasa.com Page -10- User Manual R10 – First steps –
4.1 Potential hazards 4.2 Initial check Before beginning the installation, it is advisable to check the state of the modules: 1. Check the state of the modules No knocks or apparent damage; The nameplate bearing the serial number fitted to the back of it. 2. With the aid of a multimeter measure DC voltage between the positive and negative terminals on each battery module (points 1 & 2). Check that polarity is correct and that the voltage is within range (≈ 48VDC) The retractable red lug on the cable indicates positive polarity, while its absence indicates negative polarity. On eBick-S type modules, 2 of the pins have no voltage. The diagram below shows the correct measurement points. www.cegasa.com www.cegasa.com Page -11- User Manual R10 – First steps –
3. Check the state of the MCP. No knocks or apparent damage. 4.3 Fitting the modules 1. First place the base frame on the floor and use the feet to level it. If required, secure the string to the floor, the base frame has a space where brackets can be fitted. The eBick system is designed to be stationary, with no possibility of movement and with its weight distributed evenly. 2. Stand the first eBick module on the base frame that is already level and fixed to the floor. Any module can be inserted in any order in the string, without affecting power or communications. 3. Stack the rest of eBick modules up to a maximum of 4 high. www.cegasa.com www.cegasa.com Page -12- User Manual R10 – First steps –
4. Place the MCP on top of the last module and check that the ON/OFF switch at the back is in the OFF position. 5. Use the fastening plates to fasten all the eBick modules to each other, to the base frame and to the front of the MCP. Note: Screw length is different when fastening the MCP (see picture below) www.cegasa.com www.cegasa.com Page -13- User Manual R10 – First steps –

POWER EXTENDER KIT PARALLEL Anderson connector SB350 ✓ Use the supplied protective cap to protect the power connector left uncovered on the last eBick module. www.cegasa.com www.cegasa.com Page -15- User Manual R10 – First steps –
✓ Check polarity and voltage (close to 48Vdc) on the power connector below the MCP ✓ Use the multimeter to check that there is no continuity between positive and negative on the MCP power connector (no beep) ✓ If everything is OK, proceed to connect the MCP connector to the already connected DC BUS connector. 8.2 Series connection (voltage 48V) - For eBick S cases (Anderson SB175) ✓ Without connecting to the MCP (leave this until last) start connecting all the power connectors between columns; If there are several columns, use the SERIES POWER CABLE EXTENDER KIT at the rear. POWER EXTENDER KIT SERIES Anderson connector SB175 ✓ Connect the S BRIDGE CONNECTOR to the connector on the last free module in order to close the VDC BUS www.cegasa.com www.cegasa.com Page -16- User Manual R10 – First steps –
✓ Check polarity and voltage (close to “Nº modules connected x 48Vdc”) on the power connector below the MCP. ✓ Use the multimeter to check that there is no continuity between positive and negative on the MCP power connector (no beep) ✓ If everything is OK, proceed to connect the MCP connector to the already connected DC BUS connector. 9. At the back of the MCP, connect the earth connection (M-6 bolt) to the earth for the installation. An earth cable of between 1mm2 - 2.5 mm2 section should be used (See point 7 in image below) 10. Check at the back of the MCP that there is no voltage or continuity between the poles on the positive and negative power output connectors. (See points 4 and 6 in image below) 11. At the back of the MCP connect the terminals (M-8) that corresponds to the installation’s positive and negative terminals. The recommended tightening torque is 10Nm using a torque wrench. (See points 4 and 6 in image below) 12. At the back of the MCP connect the correct RJ45 communication connectors for the inverter (MODBUS or CAN BUS). It is recommended that the cable length is no longer than 20 metres. www.cegasa.com www.cegasa.com Page -17- User Manual R10 – First steps –
Important notes: ✓ The system is self-powered and does not require connection to an external supply. ✓ The length of the interconnecting cables affects the final voltage detected by the application. It is advisable to install the battery as close as possible to the element that is going to use it (inverter, DC bus, ...) and avoid sharp curves or bends in the cables. For recommended cable lengths, wire sizes and characteristics, please contact CEGASA. 5 Commissioning the equipment 5.1 System start-up and shut-down processes All points included in the previous section should have been followed prior to starting the system. Once this has been done, the system can be started by pressing the switch on the MCP from the OFF to ON position. Pressing the switch powers up the control electronics in the MCP. The GBMS then checks hardware integrity (own hardware and that of the BMS distributed by communications) and that the cabinet distribution set-up corresponds with that read (see point 4.3). If no error is detected, the GBMS allows work with batteries to commence. The time required for start-up is less than 1 minute. To stop the system, the same switch should be changed from the ON to OFF position. The string should never be switched off while current is flowing through the system. The contactor has to be opened prior to switching off the MCP. HAZARD: ELECTRONICS SELF-CONSUMPTION The electronics inside the cabinet are powered by the batteries. If the batteries are not going to be used for a prolonged period (3-4 weeks), the MCP has to be turned off manually by pressing the ON/OFF button to OFF. 5.2 Power connection process eBick systems can operate in 2 different ways: Slave Mode and Stand-alone Mode, it is advisable ask the supply company in which mode the MCP is configured before the system is started. www.cegasa.com www.cegasa.com Page -18- User Manual R10 – First steps –
In slave mode the eBick system depends on a higher-level system, be it SCADA, an inverter or operation personnel. In this mode, after the system is started it remains in the ready/disconnected state until it receives an external close contactor command. Until this order to close the connector is received, the voltage at points 6 and 4 in the image below is 0V. In stand-alone mode (48V VICTRON or SMA type commercial converters) eBick automates several operations, including direct connection by closing the output contactor if the battery’s safety conditions are met. In this mode, after starting the eBick system by pressing the ON switch, if no critical error occurs then the output contactor closes autonomously and automatically, with points 4 and 6 in the image above having 48Vdc from the battery. Consequently, all components hooked up to the eBick system output bus are fed this nominal voltage. Likewise, it manages the resets in the event of battery alarms. 5.3 Pre-charge process (only in stand-alone mode) The pre-charge process is only used in stand-alone mode, designed to be used with commercial 48V inverters. It requires specific custom-built hardware for this application. If the bus voltage differs from 48V or if it is certain that the application requires precharge, please contact CEGASA. 5.4 ID Configuration (Only if necessary) During the initial start-up, the battery has to be configured for correct communications. In this example, let’s imagine that we have installed a 4-unit system and are going to follow the following numbered steps: www.cegasa.com www.cegasa.com Page -19- User Manual R10 – First steps –
a) We note the serial numbers for each of the battery modules. The serial number is found on a label at the back of them. b) Once the MCP is started, it displays all read values as “?” until distribution is configured. www.cegasa.com www.cegasa.com Page -20- User Manual R10 – First steps –
Otherwise, this may be because: a. These are not the configured modules (continue reading) b. There is a communication fault→Check that the cable is plugged in correctly. c. Start-up fault →Restart and recheck c) Change language and Logging as administrator - Access the "Login" button as administrator (Select the desired language from the drop-down that appears on the screen). The default user is admin and the default password cegasa. Select the desired language in drop-down. Please contact CEGASA if the access data has been changed. d) Access the pencil-shaped “Edit” button In the dialogue box enter the number of modules in series and parallel. In this example there are 4 modules to connect in series (final bus voltage of 200Vdc) and only one string to connect on the system (1 parallel). Once the number of modules has been configured, the IDs have to be configured on the “Edit MECs” screen. The following screen displays what is seen during the first start-up. www.cegasa.com www.cegasa.com Page -21- User Manual R10 – First steps –
The battery layout table on the right shows the series and parallel configuration that has been defined in the previous screen. The software does not show any of the modules during the first start-up. They have to be configured manually. To do this, click on the “Add New MEC” button as many times as there are battery modules. In this particular example, 4 times. After clicking the button, the software generates battery modules that can then be configured, and these appear inside the “Available MECs Pool” table. As they have not yet been configured, they appear with the default values. In order to identify the modules, it is best to assign the IDs so that they match the physical layout. (Module number 1 closest to the eBick) www.cegasa.com www.cegasa.com Page -22- User Manual R10 – First steps –
To change the serial and/or ID number, just click on the one that needs changing and an on-screen keyboard will appear so that the new number can be entered. Once the serial numbers have been changed to reflect the ones that had been written down, select the first one and click on the “
The screen now shows a layout that matches its physical counterpart. e) Restart the system (ON/OFF button) to apply the changes. After accepting the changes on both pop-up screens, a warning appears, stating that changes have occurred and requesting permission to restart. After restarting, the display shows the battery values. The installation is now completed. www.cegasa.com www.cegasa.com Page -24- User Manual R10 – First steps –
5.5 Current calibration (Only if necessary) Note: In order to calibrate, the user has to have accessed the system as an administrator. All eBick measurement systems are pre-calibrated at the factory. ONLY IF NECESSARY should calibration of the current transformer be checked in order to minimize possible reading errors. The following tools are required to perform this calibration: - A measurement method that can read the current flowing through the battery, such as a current clamp or the inverter itself. - Access to the equipment to charge/discharge the battery, and control over them in order to vary the current flowing to the battery. Calibration of the current transformer is done via the touch screen. This configuration is divided into 2 main parts: 1. Polarity correction On the main screen: Charge or discharge the battery, checking the current being read and battery status. If current is flowing to the battery (battery charging), current value will be positive and battery status will be “load”. If current is being drawn from the battery (battery discharging), current value will be negative and battery status will be “unload”. If during this test battery status is the opposite of its real status, the reported direction of the current can be inverted by pressing the “INV” button www.cegasa.com www.cegasa.com Page -25- User Manual R10 – First steps –
2. Current measurement correction Inside the “Calibration” sub-menu: If there is a difference between the current being read by the HMI and the current circulating through the system, the reading can be corrected with adjustments from this menu. Note: It is best to perform the calibration when the battery SoC is between 40% and 60%. Performing the calibration within this range allows the user to change between charge and discharge status, and to take several points at each of these, making it possible to perform the calibration in just one operation, without ever reaching 0% or 100% SoC, which would otherwise trip an MCP safety. Once on this screen, clicking the reset button clears any stored calibration point, leaving a blank sheet to begin the calibration. Calibration begins by charging or discharging the battery to the maximum current value indicated on the data sheet provided by CEGASA, or the maximum current the inverter can supply on the installation, whichever is less. Once the current is read and displayed in the “Measured” box, the actual current can be written in the “New current point box” and then “Add” can be clicked. The current value in the inverter can then be changed to a new point and the previous step repeated. Calibration is performed by starting at the maximum charge current, passing through several intermediate points, 0 current value, several intermediate discharge points and maximum discharge current. When calibration has finished, press “Finish” to store the new calibration points. Note: Calibration is done using the point-slope method, interpolating the calibration points between 2 manually inserted points. Consequently, it is not necessary to calibrate the current transformer at all working points because the software calculates the intermediate points. www.cegasa.com www.cegasa.com Page -26- User Manual R10 – First steps –

8 Working with the eBick 8.1 Precharge There is a differentiation between the devices connected in parallel to 48Vdc (MCP Parallel) and the equipment connected in series (MCP series) for the connection process. MCP Parallel – Parallel devices have a CONNECTED preload system to connect automatically. That is, the equipment is autonomous in the connection and reconnection of the system. For the connection it has a number of attempts in case of not being able to make it, the device will show an error indicating the alarm on the screen. MCP Series – This equipment has the preload system DISCONNECTED, so it is necessary that other equipment (inverter or similar) indicates the power connection by communications when the bus is safely preloaded. 8.2 Charging The eBick system always works with CAN BUS communications with the inverters. In this way the MCP always communicates to the inverter the charging voltage and the maximum charging current that must be respected at all times, depending on variables such as the state of charge of the battery (SOC) and the temperature of the cells. In this way, depending on the charging conditions, we optimize the process to preserve the safety and life of the batteries. This is known as the SOF (State of Function) function. 8.2.1 MCP Series Charging current by SOF SOC Charging current 1. 0-94% 180A x Temperature coefficient 2. 95-99% 20A x Temperature coefficient 3. 100% 0A x Temperature coefficient Temperature range in Temperature CHARGE (ºC) coefficient 0-5 0,1 6-11 0,2 11-45 0,5 46-50 0,1 Charging voltage by SOF Temperature range in CHARGE Charging voltage (ºC) (V) 0-5 51,2 x Nºmodules 6-11 51,5 x Nºmodules 11-45 51,9 x Nºmodules 46-50 51,2 x Nºmodules www.cegasa.com www.cegasa.com Page -36- User Manual R10 – First steps –

The minimum voltage that cannot be lowered in the discharge is sent to the inverter to ensure battery operation. This value is: Vmin = 42V x Number modules connected in series 8.4 Equalizing Equalization process in the eBick family is passive and is governed by the MCP only. The system enters in equalization mode when the voltage dispersion within the system exceeds 40mV. The equipment goes out to equalize when the voltage dispersion reaches a value of 10mV or when one of the series reaches the limit value of 3340mV. www.cegasa.com www.cegasa.com Page -37- User Manual R10 – First steps –
8.5 SOC Algorithm The MCP calculates the SOC of the eBick system at all times by coulombometry, including the internal consumption of its own electronics. To avoid accumulated errors, you have several points to update the charge status at different levels: 1. 100% update - Regardless of the SOC shown on the screen if the series voltage levels (in the CHARGE process at a certain current) reach a certain voltage value the SOC automatically changes to 100% since the MCP interprets that the system is really charged at that level. 2. 5% update - Regardless of the SOC shown on the screen if the series voltage levels (in the DISCHARGE process at a certain current) reach a certain voltage value the SOC automatically changes to 5% since the MCP interprets that the system is really discharged at that level. 3. Without current (OCV) – Regardless of the SOC shown on the screen if the series voltage levels (in the IDDLE process, current 0A) reach a certain voltage value after a stabilization time the SOC automatically changes to the value indicated in the algorithm since the MCP interprets that the system really is at that level. This update is only for SOC values below 30% 8.6 Alarm reset There is a differentiation between the devices connected in parallel to 48Vdc (MCP Parallel) and the equipment connected in series (MCP serial) for the alarm reset process. MCP Parallel – Parallel equipment has a CONNECTED preload system to automatically connect in case of alarm recovery. That is, the equipment is autonomous in the reconnection (alarm reset) of the system. For the connection it has a number of attempts (3) in case of not being able to do it due to a problem, the device will go to error indicating the alarm on the screen. Note: There are two alarms that do not have the reset process as it is understood that they are important from the point of view of system security. They are related to the voltage difference and temperature difference. If in any case the difference in voltages or temperatures exceeds a certain value for each case, it is understood that there is a damaged cell or probe (voltage or temperature) and the process of automatic reset of alarm is eliminated. MCP Serie – Serial equipment has the preload system DISCONNECTED, so it is necessary that the inverter indicates the reconnection of the power by communications when the bus is safely preloaded and the battery has no alarm on screen. www.cegasa.com www.cegasa.com Page -38- User Manual R10 – First steps –
8.7 Ultra-consumption mode In the case that there is any problem in the discharge process or in the disconnection of the equipment, the MCP has an added security accessing the ultra-consumption mode to preserve the life and safety of the batteries avoiding overloading them. In this way, if the MCP detects that one of the series is below the established safety threshold, it initiates a disconnection protocol (ultra-consumption mode) to ensure the safe mode of operation of the batteries. In this way the consumption of the screen, the output contactor (if powered), the BMS and all the electronics of the MCP are canceled. The only way out of this state is to turn the MCP of the power button off and on again. Contact CEGASA if the equipment has entered in this mode to ensure system re- establishment. 9 Environmental operating conditions Parameters Technical Observations specifications Temperature range in CHARGE (ºC) 0ºC ~ + 50ºC Temperature range in DISCHARGE (ºC) -20ºC ~ + 50ºC Humidity (RH%) 5%≤RH≤85% 10 Maintenance and storage procedure The customer is responsible for complying with this procedure: ✓ Check monthly the voltage (within the range of the battery) and the visual state of the envelope (no bumps, swelling or discoloration) and the positive and negative terminals in MCP (no oxidation), check the tightening of the latter to the output cable. ✓ Every 12 months it is mandatory to carry out a battery charging process up to 40 - 60% SoC.
