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.
