To calculate a charging fee which reduces unfairness for each vehicle without loading a watthour meter.SOLUTION: A vehicle charger for charging a vehicle comprises: current measuring means for measuring charging current; detection means capable of detecting that the charging current has exceeded a set first threshold value and that it has become lower than the value; time-measuring means which measures a first time being a time from detecting that the charging current has exceeded the first threshold value to detecting that it has become lower than the first threshold value; and a control device which utilizes a maximum value of the charging current measured by the current measuring means and the first time measured by the time-measuring means, for calculating a charging fee.SELECTED DRAWING: Figure 6
【課題】電力量計を搭載せずに、車両毎の不公平感を軽減する充電料金を算出すること。【解決手段】車両を充電する車両用充電器であって、充電電流を計測する電流計測手段と、設定した第1の閾値を充電電流が上回ったことと下回ったことを検知可能な検知手段と、充電電流が第1の閾値を上回ったことを検知してから第1の閾値を下回ったことを検知するまでの時間である第1の時間を測定する計時手段と、電流計測手段が計測した充電電流の最大値と、計時手段により測定された第1の時間を充電料金の算出に利用する制御装置と、を備えた構成とする。【選択図】図6
