Abstract: The present disclosure includes an automotive battery system that uses switching devices to increase operational performance and reliability. The battery system includes a battery cell, a primary switching device electrically coupled to a terminal of the battery cell, and a secondary switching device electrically coupled to the terminal of the battery cell and in parallel with the primary switching device. The primary switching device includes an electromechanical switching device that enables charging or discharging of the battery and generates a boosted voltage. A secondary switching device includes a solid-state switching device and a diode, electrically coupled in series, which detect short circuit conditions in a power-efficient manner and remove the short circuit condition by using the boosted voltage to actuate the armature. Furthermore, parallel switching devices work together to deliver appropriate amounts of power as required by an electrical device, increasing the performance, reliability, and life-span of a battery system.

Abstract: 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.
