Figure 4-4 Cable connections to Hall effect sensors (1)

If the battery string is not configured with a neutral wire, connect the Hall effect sensor on the positive

or negative battery string cable to the HALL_1 current monitoring port on the CIM.

If the battery string is configured with a neutral wire and each of the positive and

negative battery string cables connects to two or more Hall effect sensors. For example,

if each of the positive and negative battery string cables connects to two Hall effect

sensors, connect the Hall effect sensors on the positive battery string terminal side to the

HALL_1 and HALL_2 current monitoring ports on the CIM, and connect the Hall effect

sensors on the negative battery string terminal side to the HALL_3 and HALL_4 current

monitoring ports on the CIM.

If the positive or negative battery string cable is too thick to be routed through the Hall effect sensor, or

the measurement range of the Hall effect sensor is not enough, you can connect two or more Hall effect

sensors to each of the positive and negative battery string cables to monitor the current of one battery

string.
