Prismatische Batterie mit Kühlstruktur und damit aufgebauter Batteriesatz

摘要

A battery pack (1) includes a plurality of prismatic batteries (2) each including an electrode plate group and electrolyte housed in a prismatic battery case (13), the prismatic batteries being arranged in parallel and integrally bound. A metal plate (17) is integrally embedded in the sidewall of the prismatic battery which is in parallel with the electrode plate group. A heat transfer part (18) protruding from the prismatic battery case is provided in at least one side of the metal plate (17). A heat exchanger (10) is provided such that a heat exchanging surface (11) of the heat exchanger is brought into contact with the heat transfer part protruding from the prismatic battery case of the prismatic battery and the battery pack and the heat exchanger are fixed together.
