Warming electric battery to improve performance and prevent damage, applicable to electric and hybrid vehicles

摘要

A vehicle traction battery is cooled by the circulation of a liquid around the double skin (1) of the battery container using a pump (3) and cooling equipment (5). When warming is needed, for example to enable prompt use following parking in cold weather, air between the double skin and an insulating tank (2) is heated and circulated by a resistor/fan unit (6) which is controlled by the existing battery management module (7)
