Abstract
The present disclosure relates to devices, systems, and methods for jump starting an electric vehicle. In some embodiments, an electric vehicle includes battery charging circuitry electrically connected to a high voltage storage system and a low voltage storage system mounted in the vehicle. The high voltage storage system may be configured to drive a motor for propelling the vehicle. The low voltage storage system may be configured to drive a contactor electrically connected between the high voltage storage system and a drive train of the vehicle. In some implementations, the vehicle may include an electrical connection that is easily accessible and configured to supply power from an external power source to the low voltage system. The electrical connection may be integrated into a standard trailer wiring system.
