    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 is disclosed. The battery module, in one implementation, comprises a housing having a terminal, an electrochemical cell in the housing, a relay controlling a current available from the electrochemical cell to the terminal, and a multi-function relay driver electrically coupled to the electrochemical cell, the relay, and an external load. The relay includes a relay coil to control a state of the relay. The multi-function relay driver comprises a drive to provide a first current to the relay coil to control the state of the relay. The multi-function relay driver further provides a second current. The multi-function relay driver further comprises a direct-current-to-direct-current (DCDC) converter coupled to the drive. The DCDC converter receives the second current and converts the second current to a third current for the external load. Also disclosed are method of operating the battery module.

    Abstract: Present embodiments include a control system for one or more battery cells. The control system includes a bi-stable relay configured to switch a state of the bi-stable relay upon receiving a control signal to electrically connect or electrically disconnect the one or more battery cells to a bus and to remain in the state after receiving the control signal. The control system includes a controller configured to be operatively coupled to the bi-stable relay and configured to send the control signal indicative of instructions to control operation of the bi-stable relay based on the state.
