LITHIUM ION BATTERY PACK FOR VEHICLE

摘要

PPROBLEM TO BE SOLVED: To improve cycle characteristics and improve heat radiation characteristics in a lithium ion battery pack for a vehicle. PSOLUTION: This lithium ion battery pack 10 includes a laminated body 16 to laminate alternately four lithium ion batteries 12a, 12b, 12c, 12d, and five sheets of metal heat radiation plates 14a, 14b, 14c, 14d, 14e on whose surface an insulating treatment is applied. The respective lithium ion batteries have a metallic flat-box type cabinet, and contacts with both side faces of the respective lithium ion batteries, and the respective metallic heat radiation plates of which the insulating treatment is applied on the surface are arranged. A pair of end plates 18a, 18b, and tightening belts 20a, 20b mounted on the end plates 18a, 18b are installed at a circumference of the laminated body 16, and the end plates 18a, 18b and the tightening belts 20a, 20b are mutually tightened.
