METHOD AND SYSTEM FOR UTILIZATION OF REGENERATIVE BRAKING ELECTRICAL ENERGY FOR OPERATING AUXILIARY SYSTEM IN AN OFF-HIGHWAY VEHICLE

摘要

Electrical power from a dynamic braking process in an off-highway vehicle is used to power an auxiliary system in the vehicle. The auxiliary system may be a urea storage container heating unit or a particulate filter regeneration heating unit. When dynamic braking electricity is unavailable, and to the extent the dynamic braking electricity is insufficient for powering the auxiliary system, electrical power from an energy device on board the vehicle is used to power the auxiliary system. The energy device may be an auxiliary energy storage device, devoted for use in powering the auxiliary system.
