PROBLEM TO BE SOLVED: To make service life of a driving-battery longer by separately disposing, at a position suitable for achieving longer service life, a first battery having a battery structure suitable for supplying a large input and output current and a second battery having a battery structure which has excellent service life characteristics, though it cannot supply a large input and output current.SOLUTION: A driving-battery is constituted of two kinds of batteries, that is, a first battery 23 and a second battery 25. The first battery has a battery structure capable of supplying an input and output current larger than the second battery, and the second battery has a battery structure which has excellent service life characteristics, though it cannot supply an input and output current larger than the first battery. Further, the first battery is disposed in a front part of a vehicle so as to enable cooling by introducing outside air, and the second battery is disposed inside a cabin while being separated from the first battery.SELECTED DRAWING: Figure 1

    【課題】本発明の少なくとも一つの実施形態は、大きい入出力電流を流すのに適した電池構造を有する第1電池と、大きい入出力電流を流すことはできないが寿命特性に優れる電池構造を有する第2電池とを、寿命化に適した位置に分離配置して駆動用電池を長寿命化することを目的とする。【解決手段】記駆動用電池は、第1電池と第2電池の2種類の電池からなり、第1電池23は前記第2電池25より大きい入出力電流を流すことができる電池構造を有し、第2電池は前記第1電池よりも大きい入出力電流を流すことはできないが寿命特性に優れる電池構造を有し、第1電池は、外気導入により冷却可能に車両の前方部分に配置され、第2電池は、前記第1電池とは分離して車室内に配置されることを特徴とする。【選択図】図1
