32 5. BCI USE 5.1 General information The CAN Battery Communication Interface is monitoring the batteries for proper operation. The CAN Battery Communication Interface is not a BMS (Battery Management System). In a Super B system every single battery has its own BMS and therefore makes its own decisions. The CAN Battery Communication Interface collects the information of all individual batteries in the system, and presents it as one battery bank. The CAN Battery Communication Interface can be configured for different topologies up to 127 batteries in one battery bank. The CAN Battery Communication Interface collects the status and error messages of all the individual batteries in the system. In case of a battery or communication error, the CAN Battery Communication Interface will disconnect the battery bank from the load and/or charger by opening the safety relays. The BCI is equipped with 2 communication ports, one dedicated CAN port for the batteries and a second CAN port for communicating with an external network. All system and individual battery parameters are available on the Slave communication port. Including Commands to control the battery string. 5.2 Operation The BCI is a stand alone device, meaning that no PC or other device other then batteries are required for proper operation. The BCI monitors all connected batteries through the CAN bus. Whenever one or more batteries report an error, for example excessive temperatures or high charge currents, the BCI will switch off the main relay(s) to avoid any unsafe situation. When the error is recovered, the BCI can enable the main relay(s) again. This can be done in 3 ways: manually (J3), through the battery monitor application, automatically. Depending on preference, the auto-recover function can be enabled or disabled through the battery monitor application. Copyright 2016 Super B B.V. Hengelo, The Netherlands 32 of 51

33 5.3 Power The BCI is powered on pin 10 of J4, 60Vdc. Pin 9 of J4 is the power sense line, this sense line is used for automatic deep discharge recovery for system 60Vdc. On systems with a battery voltage >60Vdc pin 10 of J4 is powered with an external power source, up to 60Vdc. Pin 9 of J4 is not used, meaning that the automatic deep discharge recovery is disabled. When the battery bank is in a deep-discharge situation, the BCI will first disable the main relay(s), and then enter a deep-sleep mode to prevent further discharge of the battery bank. In this situation the system can only be enabled again by applying a charge voltage, for example by a generator or charger. The BCI will then awake from its deep-sleep mode and enable the system again. Some chargers and inverter units cannot charge without a battery directly connected to system, and therefore may not be able to apply a charge. In this case, disconnect the BCI from the battery bank for 10 seconds and reconnect it, connector J4. The BCI will restart and will allow 1 Ah throughput from the battery bank before it will disable the system again. When charging starts, the BCI will recognize it and return to normal operation when appropriate. 5.4 Protection relays The BCI can control 2 protection relays: 1. Main High Side () 2. Main Low Sid (-) When the system switches on the main low side is closed directly. To minimize the inrush current main high side relay can only be closed if the voltage difference measured over the relay is less then 0,5V x [number of batteries] for 3 seconds. See paragraph 5.5 Recovery / pre-charge and paragraph 5.6 Pre-charge. In case of an error both relays will be opened simultaneously. In general, for systems 60Vdc only the Main High Side relay is used. 5.5 Recovery / pre-charge Capacitive loads can cause high inrush current. To protect the relays is advised to limit the current with a pre-chare resistor. For systems 60Vdc and with a pre-charge current les then < 2,5A the pre-charge resistor can be directly connected to Pin 1 and 2 of J3. For pre-charge currents > 2,5A or for systems with a battery voltage >60Vdc see paragraph 5.6 Pre-charge. The resistor is also used for deep discharge recovery. If one ore more batteries are reporting a deep discharge voltage the Recovery resistor limits the charge current until all errors are Copyright 2016 Super B B.V. Hengelo, The Netherlands 33 of 51

34 cleared. When all errors are cleared the main high side relay will close and de recovery / precharge resistor will be disconnected to allow maximum charge current. 5.6 Pre-charge For limiting the inrush current for systems >60Vdc or for pre-charge current >2A an external pre-charge relay can be connected to Pin 3 and 4 of connector J4. The switching behavior is the same as for the internal Recovery / Pre-charge circuit. The pre-charge resistor value can be calculated as follows: Batteries in series Maximum Resistor Value Power 1 (1 * 13,3V) / 2,5A = 5,32Ω 2,5 2 * 5,32 = 33,25W 2 (2 * 13,3V) / 2,5A = 10,64Ω 2,5 2 * 10,64 = 66,5W 3 (3 * 13,3V) / 2,5A = 15,96Ω 2,5 2 * 15,96 = 99.75W 4 (4 * 13,3V) / 2,5A = 21,28Ω 2,5 2 * 21,28 = 133.0W Table 27 Pre-charge resistor value 5.7 CAN bus General information To use the BCI, the CAN Master bus needs to be connected to the Super B Li-Ion batteries More information on the CANOpen bus can be found at the CiA website: The required documentation can be found in the following CiA documents: (or in a future version of these documents.) CiA 301 CiA 303_1 V1.8.0; Sections 5 (AC and DC parameters) and 7.2: (5-pin micro style connector) CAN Bus network topology The CAN Bus must be used in a bus network topology (see Figure 14 CAN Master bus, Figure 15 CAN slave bus and Figure 16 ). Do not use a ring- or a star topology. The CAN specifications restrict the Bus length/bus speed. Displayed in Table 2 is an overview of these restrictions. Bit rate Bus length (L) Max. stub length (S) Accumulated stub length 250 Kbit/s 250m 11m 55m Table 28 CAN Bus lenght The default speed of the Can BUS is 250 kbit/s. A high speed bus requires termination at the two ends of the bus. Copyright 2016 Super B B.V. Hengelo, The Netherlands 34 of 51

35 Termination Resistors Use termination resistors at the end nodes to impede reflections on the line. The value of this resistor should be /- 120 ohms. More information on termination resistors can be found in CiA document 303_1 V1.8.0, section 5. CAN bus power Due to the galvanic isolation of the CAN interface of the batteries, an external power supply is needed for powering the CAN bus. Therefore, the BCI powers the CAN Master bus. The CAN slave bus is not powered by the BCI! Integrating CAN Protocol For integrating the Super B CAN protocol please contact you Super B sales representative. 5.8 Configuration Before the BCI and battery bank can be used, a few configurations need to be made with the Super B battery monitor application. For connecting a computer to the BCI a CAN to USB converter is required, see 2.8 Peripheral equipment. Refer to paragraph for connecting the CAN to USB converter to the BCI. Battery ID s In multi-battery systems, each battery shall have a unique Node ID number. The default Node ID for a Super B battery is 10. This number shall be changed depending on the configuration. If the system as a whole has been ordered at Super B, the batteries will have been preconfigured and renumbering is not necessary. If this is not the case, renumbering can be done manually. Any Node ID number between 2 and 127 can be assigned to a battery. Node ID 1 should not be used for batteries as it is reserved for the BCI. We recommend not to use Node ID 10 for multi battery configurations as it may be confusing in case a battery is added to the system. Multiple batteries with the same number will result in unpredicted behavior of the system. We recommend numbering of the batteries in such a way that the bank configuration (number in parallel, number in series) can be easily recognized. Copyright 2016 Super B B.V.

46 9. DISPOSAL The BCI is classified as Small IT waste. The BCI is compliant with WEE and Rohs. WEEE The European Waste Electrical and Electronic Equipment Directive (WEEE) applies to a wide range of electronic and electrical products. WEEE encourages the collection, treatment, recycling and recovery of waste electrical and electronic equipment. WEEE makes producers and importers responsible for financing of the collection, treatment and recovery of WEEE. Reference: The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC, as amended by 2003/108/EC. Rohs The RoHS Directive will ban placement into the EU market of new electrical and electronic equipment containing more than designated maximum allowable levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants, effective July 1, RoHS works in conjunction with the EU WEEE Directive. RoHS supports WEEE by reducing the amount of hazardous chemicals used in production. In turn it reduces the risk of exposure to recycling staff as well as reduction in recycling costs. Manufacturers will need to ensure that their products, parts and components comply with RoHS in order to be distributed and sold in the EU.
