This Standard specifies communication protocols between battery management system (hereinafter referred to as BMS) and off-board charger (hereinafter referred to as charger) for electric vehicles. This Standard applies to off-board charging for electric vehicles. CAN identifier of this Standard is 29 bits, and communication baud rate is 250 kbps, but this Standard is not limited to 29-bit identifier and 250 kbps communication baud rate. If other formats are used, their CAN identifier shall be made by reference to this Standard. Data transmission of this Standard is by the format of low bits transmitted first. Negative current value represents charging; positive current value represents discharging.
