 The BMS B2A245-20P documentation describes a CAN interface but it's only optional (can be customised). But a RS485 interface is standard named //GPS//. In fact it's a serial interface with 3.3V level shifter inside and MODBUS protocol.

 CAUTION: The power pin VCC at RS485/GPS connector is VBAT. That means we will see a voltage of 45-58V (=battery voltage) at this terminal.
