Abstract
A system and method for heating or cooling a battery include a controller and a tempering circuit containing an auxiliary medium configured to exchange heat with a container having a latent heat storage medium, and a vehicle traction battery, a pump configured to circulate the auxiliary medium, and an activation device having a sealing element moveable to selectively expose a nucleation surface to the latent heat storage medium to trigger a phase change process and exchange heat with the auxiliary medium.
Claims20
A system comprising:
- a controller;
- a battery arranged to transfer heat to and from an auxiliary medium of a tempering circuit;
- a container in the tempering circuit containing a latent heat storage medium;
- and
- an activation device having a nucleation surface and a sealing element selectively moveable responsive to a request from the controller to expose the nucleation surface to the latent heat storage medium to trigger a crystallization process and heat the auxiliary medium.
A method for heating a battery, comprising:
- controlling, by a controller, an activation device to expose a nucleation surface to cause a phase transition of a latent heat storage medium to heat an auxiliary medium that circulates through a tempering circuit containing the battery.
A system comprising:
- a controller;
- a tempering circuit containing an auxiliary medium configured to exchange heat with a container having a latent heat storage medium, and a vehicle traction battery;
- a pump configured to circulate the auxiliary medium;
- and
- an activation device having a sealing element moveable to selectively expose a nucleation surface to the latent heat storage medium to trigger a phase change process and exchange heat with the auxiliary medium.
