The system current changes after different Numbers of packs are connected in parallel, and the current is
generally larger than one single pack. The selection of switches connected to PCS should be based on the
maximum battery current decided by the PCS or the actual working current. If the D.C. switch is not suitable,
then a circuit breaker can be considered.

The
D.C. isolating
