battery thermal management using phase change material

A device for thermal management of a battery, comprising:

• a battery;
• and
• a latent heat storage material, which may change its phase from liquid to solid and which may give off heat of crystallization in the process to heat up the battery, the crystallization being triggerable by a pulse.

A device for thermal management of a battery, comprising:

• a battery;
• and
• a latent heat storage material, which may absorb excess heat of the battery and, in the process, change its phase from solid to liquid and thus cool the battery.

A method for heating a battery, the method comprising:

• bringing the battery into contact with a latent heat storage material, and the latent heat storage material is in a liquid phase, and the latent heat storage material may change its phase from liquid to solid and give off heat of crystallization in the process to heat up the battery;
• and
• triggering a crystallization of the latent heat storage material by a pulse.

A method for cooling a battery, the method comprising:

• bringing the battery into contact with a latent heat storage material, the latent heat storage material being in a solid phase and the latent heat storage material may absorb heat and change its phase from solid to liquid in the process.
