Battery e.g. high voltage electric power supply battery, heating device for hybrid vehicle, has equipment connected on exhaust line to provide heat to battery, and pump permitting flow of coolant in heater circuit when engine is stopped

摘要

The device has exhaust heat recovery equipment (RTE) connected on an exhaust line (10) of a heat engine (12) for providing heat to a battery e.g. high voltage electric power supply battery (16) of an electric motor of a hybrid vehicle. The battery is placed in an enclosure (18) that is provided with a liquid/air heat exchanger (20). The equipment has a liquid/air exchanger (13) with outlet (22) and inlet (34) that are connected by a pipe (25) containing coolant. An electric pump (26) permits the flow of the coolant in an air heater circuit (36) when the engine (12) is stopped. An independent claim is also included for a method of heating an electric power supply battery.
