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.
