5.2 Connecting Cables
1. Connect the cable between the CIM and the Hall effect sensor.
•
If each of the positive and negative battery string cables connects to one Hall effect sensor,
connect the Hall effect sensor on the positive battery string terminal side to the HALL_1 current
monitoring port on the CIM, and connect the Hall effect sensor on the negative battery string
terminal side to the HALL_2 current monitoring port on the CIM.
•
If each of the positive and negative battery string cables connects to two or more Hall effect
sensors, connect the Hall effect sensors on the positive battery string terminal side to the former
HALL current monitoring ports, and the Hall effect sensors on the negative battery string terminal
side to the latter HALL current monitoring ports. 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.
When one CIM manages multiple battery strings, first connect the Hall effect sensors on the
positive and negative cables for battery string 1 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.
