Abstract:
Systems and methods for switching high-voltage contactors in a battery system with reduced degradation over time are presented. In certain embodiments, a system may include solid-state switches disposed is parallel with the high-voltage contactors. The solid-state switches may be configured to selectively close when the high-voltage contactors are in transition from a closed state to an open state. By closing the solid-state switches during this transition, electrical arcing and associated degradation and/or damage to the contactors may be reduced.
