Abstract:
An electric vehicle charging port includes a pair of charging pins each connected to a respective charging cable by a base. A pair of porous metallic cages surround the base of the pair of charging pins. A phase change material disposed in the pair of porous metallic cages and a vapor chamber is disposed between the base of the pair of charging pins and the pair of porous cage. The phase change material with an optional vapor chamber and high thermal conductivity (metal or graphite) foam or mesh to provide faster response of transient heat generation.
