Abstract

See full text

A battery module may include a housing, a plurality of battery cells disposed in the housing, a battery terminal extending from the battery module for coupling the battery module with electrical components in the vehicle, and a contactor. A voltage supplied to a relay coil in the contactor may generate a magnetic field to actuate a contactor switch. The battery module may also include a printed circuit board (PCB) disposed in the housing. The PCB may include a relay control circuit configured to control a current flowing across the relay coil, and the relay control circuit may operate in a pull-in mode to transition the contactor switch into a closed position and in a hold mode to maintain the contactor switch in the closed position.
