Grupo Quejido Polígono Malpica - 50016 - Zaragoza (Spain) info@epicpower.es - www.epicpower.es AN0029 Smart Battery Charging device Smart Battery Charging device 1. General description The “Smart Battery Charging Device” is an add-on device to the EPC series converters that communicates through CAN with them to command the charging operation of a battery. The “Smart Battery Charging Device” can integrate a battery charging profile inside that regulates the different stages of charge needed in a battery. The device supports the charging of any kind of battery (lead-acid, lithium…) that works within the range of operation of the EPC series converter installed. Fig. 1: CAN – Smart Battery Charging Device The “Smart Battery Charging Device” ensures the correct charge of the battery, its safety and reliability

Fig. 2: Connectors available (subject to change) Element 1: EPC communication cable connector This connector is used to communicate the DC/DC converter (EPC) and the “Smart Battery Charging device”. It is a standard RJ-45 socket If the installation has more than one EPC external interface module, this cable should be connected to CONNECTOR Element 2: CAN Bypass connector This is a CAN Bus bypass connector used where multiple interfaces are available at the installation to create a daisy-chain. In this case, the cable should be connected to the CONNECTOR 1 of the downwards interface by a...

Element 4: Node ID Configuration Switch This switch allows to configure the battery charging profile between different available ones. Fig. 3 Node-ID Configuration Switch Element 5: External CAN communication This connector is used to communicate an external BMS to the “Smart Battery Charging device”. It is currently not used in the “Smart Battery Charging device”. It is a standard RJ-45 socket Element 6: Temperature sensor and enable. 4 ways connector that includes temperature (thermocouple) and opto-coupled enable input. Epic Power Converters, S.L.

2.1. EPC Dual CAN interface Description CONNECTOR 7 : CAN Bus #1. Reserved for custom applications. Terminal CONNECTOR 8 : CAN Bus #2. Connection with external controller. Terminal CAN 1 and CAN 2 are electrically isolated. 2.2. EPC Connection Cable (optional) Cable used to connect EPC DC/DC Converter with other CAN Interface devices. 2.3. RJ-45 cable (Optional) Cable used to connect diverse EPC interfaces together in a daisy-chain mode. 2.4. CAN Bus line terminator (Optional) The CAN Bus requires to be terminated by a 120 Ohm resistor; this can be achieved in a reliable way by using our...

3. Installation procedure 1. Make sure EPC series converter is OFF (HVDC and LVDC connections are voltagefree). 2. Plug the connection cable in connector 1 of the “Smart Battery Charging Device” and connector 8 of the “EPC Dual CAN Interface” (in the DC/DC converter side). If your installation consists on more than one EPC External interface, refer to the following schematic (Fig. 7) for connection. 3. Use the 5-Way switch (4) configuration to configure the battery charging profile according to the current installation. 4. Cable the temperature sensor and the enable to the 4 ways connector...
