METHOD AND DEVICE PROVIDING THE TEMPERATURE REGULATION OF A RECHARGEABLE ELECTRICAL ENERGY STORAGE BATTERY

摘要

The invention relates to a device (10) providing temperature regulation for at least one rechargeable electrical energy storage battery (11), particularly a battery of an electric traction or hybrid vehicle, comprising at least one electrochemical component, characterized in that it comprises at least one chamber (12) in which the said electrochemical component of the said battery is housed, at least one magnetocaloric heat pump (13, 23) associated with the said chamber, at least one circuit (15) for the circulation of a heat-transfer fluid coupled between the said battery and the said heat pump and at least one heat exchanger member (14) open to the external surroundings and connected to the said heat-transfer fluid circulation circuit in order to exchange heat energy with the said external surroundings.
