To shorten the charging time at low temperature in a commercial electric vehicle.SOLUTION: A vehicle 12 includes a battery control device 34 for controlling charging and discharging for a battery 32 for power. The battery control device 34 includes a charge/discharge control unit 40 for controlling charge/discharge so that an electricity storage amount of the battery is within a predetermined management range, an outside temperature acquisition unit 46 for acquiring the outside temperature, and an upper limit electricity storage amount setting unit 42. In a case where the acquired outside temperature is lower than a predetermined temperature, the upper limit electricity storage amount setting unit 42 sets an upper limit electricity storage amount, which is an upper limit value of the management range of the electricity storage amount, to an upper limit electricity storage amount at low temperature which is lower than the upper limit electricity storage amount when the outside temperature is higher than the predetermined temperature. The battery control device further includes a lower limit electricity storage amount setting unit 44. In the case where the acquired outside temperature is lower than the predetermined temperature, the lower limit electricity storage amount setting unit 44 sets a lower limit electricity storage amount, which is a lower limit value of the management range of the electricity storage amount, to a lower limit electricity storage amount at low temperature which is lower than a lower limit electricity storage amount when the outside temperature is higher than the predetermined temperature.SELECTED DRAWING: Figure 3
【課題】商用電動車両において、低温時の充電時間を短くする。【解決手段】車両12は、動力用の電池32に対する充放電を制御する電池制御装置34を備える。電池制御装置34は、電池の蓄電量を所定の管理範囲内となるように充放電を制御する充放電制御部40と、外気温を取得する外気温取得部46と、取得した外気温が所定気温より低いとき、蓄電量の管理範囲の上限値である上限蓄電量を、外気温が所定気温より高いときの上限蓄電量より低い低温時上限蓄電量に設定する上限蓄電量設定部42とを有する。さらに、取得した外気温が所定気温より低いとき、蓄電量の管理範囲の下限値である下限蓄電量を、外気温が所定気温より高いときの下限蓄電量より低い低温時下限蓄電量に設定する下限蓄電量設定部44を有する。【選択図】図3
