  • Publication number: 20150380783
    Abstract: A thermal control device for at least one rechargeable electrical energy storage battery, in particular for a battery of a vehicle with electric or hybrid drive and comprising at least one electrochemical component. The device comprises at least one enclosure in which the electrochemical component of the battery is housed, at least one magnetocaloric heat pump associated with the enclosure, at least one heat transfer fluid circulating circuit coupled between the battery and the heat pump and at least one heat exchanging component that is open to the exterior environment and connected to the heat transfer fluid circulating circuit to exchange calories with the exterior environment.

  • Patent number: 9091465
    Abstract: A method for generating a heat flow from a magnetocaloric element (1) comprising at least one magnetocaloric material (2) comprising a hot end (3) associated with a hot chamber (4) and a cold end (5) associated with a cold chamber (6), the method comprises magnetically and alternately activating and de-activating the magnetocaloric element (1) and circulating a heat transfer fluid through the magnetocaloric element (1) alternately towards the hot chamber (4) and the cold chamber (5) in synchronisation with the magnetic activation and de-activation phases. This method is characterized in that the method comprises reversing the direction of circulation of the heat transfer fluid during the magnetic activation and de-activation phases and also relates to a magnetocaloric heat generator implementing the method.
