To make sure that electricity charge does not fluctuate according to the amount of a charging current.SOLUTION: At a vehicle base 40, a charging device includes a plurality of chargers 10-1 to 10-3 that charge an in-vehicle battery of an EV bus by at least one of two charging methods (quick charging, normal charging), and a charge control device 20 to which a current is supplied to charge each in-vehicle battery with multiple chargers, and determines a charging method such that the total current for charging the plurality of in-vehicle batteries does not exceed an upper limit (contract current) that is the basis for calculating the power charge.SELECTED DRAWING: Figure 1
【課題】充電電流の量に応じて電力料金が変動しないようにする。【解決手段】車両基地40において、充電装置は、少なくとも二つの充電方式(急速充電、普通充電)のいずれかでEVバスの車載電池を充電する複数の充電器10−1〜10−3と、複数の充電器で各車載電池を充電するための電流が供給され、複数の車載電池に充電する電流の総和が、電力料金を算出する基礎となる上限値(契約電流)を超えないよう、充電方式を決定する充電制御装置20とを備える。【選択図】図1
