<p><P>PROBLEM TO BE SOLVED: To provide a battery pack capable of preventing corrosion and leakage of a unit battery container due to dew condensation while securing heat radiation of an assembled battery. <P>SOLUTION: The battery pack 100 includes the assembled battery 10, a housing case 30 to house the assembled battery 10, and a cooling air supply port 40 to supply cooling air into the housing case 30. The assembled battery 10 has a plurality of unit cells 20 capable of charge and discharge connected mutually electrically, and the plurality of unit cells 20 respectively have an electrode having a positive electrode and a negative electrode and a container 60 to house the electrode and an electrolyte. The outer wall to constitute the unit cell container 60 is composed of an insulation treatment part 67 applied with electric insulation treatment and a non-insulation treatment part 61 which is not treated with electric insulation treatment. The insulation treatment part 67 is formed at the end 66a on the cooling air supply port 40 side of the unit cell container 60 and at the position where the cooling air from the cooling air supply port 40 can contact. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
