PROBLEM TO BE SOLVED: To provide a battery controller for vehicle capable of increasing the power storage capacity that can be used in the whole battery pack, while facilitating the mounting on a vehicle.SOLUTION: In a vehicle VE, a first battery pack 2 is placed in a high temperature region HT, and a second battery pack 3 is placed in a low temperature region LT. Multiple temperature sensors 7 detect a temperature Tb1 of the first battery pack 2 and a temperature Tb2 of the second battery pack 3, respectively. An energization detector 82 calculates a resistance value Rb1 of the first battery pack 2 and a resistance value Rb2 of the second battery pack 3, from the detected temperatures Tb1, Tb2, and a temperature resistance characteristics map stored in a characteristics map storage section 81. A temperature control section 83 calculates a target temperature Tbt of the first battery pack 2 so as to equalize the resistance values Rb1, Rb2, on the basis of the temperature resistance characteristics map. The temperature control section 83 adjusts an ambient temperature of the first battery pack 2 by operating a temperature regulator 9, so that the temperature Tb1 of the first battery pack 2 becomes the target temperature Tbt.SELECTED DRAWING: Figure 1

    【課題】組電池全体において使用可能な蓄電容量を増大させることができるとともに、車両への搭載を容易にする車両用電池制御装置の提供。【解決手段】車両VEにおいて、第1組電池2は高温領域HTに配置され、第2組電池3は低温領域LTに配置されている。複数の温度センサ7は、第1組電池2の温度Tb1および第2組電池3の温度Tb2をそれぞれ検出している。通電検出部82は、検出された温度Tb1、Tb2と、特性マップ記憶部81に記憶された温度抵抗特性マップとから、第1組電池2の抵抗値Rb1および第2組電池3の抵抗値Rb2を算出する。温調制御部83は、温度抵抗特性マップに基づいて、抵抗値Rb1、Rb2を互いに等しくするために、第1組電池2の目標温度Tbtを算出する。温調制御部83は、第1組電池2の温度Tb1を目標温度Tbtにするため、温調装置9を作動させて第1組電池2の周辺温度を調整する。【選択図】図1
