Communication

Figure 8: BMS communication ports

The BMS is equipped with three communication interfaces hosted over five connection ports.
The Communication ports are split into two domains. Each domain is marked in the board with
white contour line and carries an isolation rating of 1500Vdc.
-

Isolated Domain 1: Screw connector 1, RJ45 connector 1 and RJ45 connector 2 are for

the CANBUS 1 interface.
-

Isolated Domain 2: RJ45 connector 3 and RJ45 connector 4 are both denoted to the

CANBUS 2 and RS485 interfaces as well as for the remote ON funtinction.
