
If the battery string is configured with the neutral wire, measure the currents of the positive and
negative battery string cables. If the battery string is not configured with the neutral wire, measure
the current of either the positive or negative battery string cable. The following uses the scenario
where the battery string is configured with the neutral wire as an example.

When a CIM manages multiple battery strings, first connect the Hall effect sensors on the positive
and negative cables of battery string 1 respectively to the corresponding ports on the CIM. Then
connect the Hall effect sensors on battery string 2 to the CIM in the same way, and so on.
