PROBLEM TO BE SOLVED: To provide a technology for raising the battery temperature efficiently by using a Peltier element.SOLUTION: The battery pack for vehicle includes a Peltier element, a battery, a heat exchanger plate for transferring heat radiated from the radiation surface of the Peltier element to the battery, and a first flow path for introducing the air warmed by the heat radiated from the battery to the heat absorption surface of the Peltier element. The Peltier element and the first flow path are disposed on the upstream side of the battery. Preferably, the first flow path has a part of restrictor shape for introducing the air warmed by the heat radiated from the battery and rising by natural convection to the heat absorption surface by Venturi effect. |
