The present subject matter relates to a battery module for use in a vehicle. The battery module may include a housing, a plurality of battery cells disposed within the housing, and solid state pre-charge control circuitry that pre-charges a direct current (DC) bus that may be coupled between the battery module and an electronic component of the vehicle. Furthermore, the solid state pre-charge control circuitry may include solid state electronic components as well as passive electronic components.
