To provide a battery charger of a vehicle and method for determining a vehicle model of a charge vehicle.SOLUTION: A battery charger 1 for charging a vehicle includes current measurement means for measuring a charging current. A vehicle model is determined by using a frequency or a continuous time of one of three times. The three times include: the first time being the time from the time when it is detected that a charging current exceeds a set first threshold to the time when it is detected that the charging current becomes lower than the first threshold; the second time being the time from the time when it is detected the charging current becomes lower than a second threshold, which is set to be larger than the set first threshold and to be smaller than a peak current, to the time when it is detected that the charging current becomes lower than the first threshold; and the third time being the time from the time when the charging current becomes lower than the set first threshold to the time when the charging current exceeds the first threshold.SELECTED DRAWING: Figure 12

    【課題】充電車両の車種を判定する車両用充電器及び方法を提供する。【解決手段】車両を充電する車両用充電器1であって、充電電流を計測する電流計測手段を備え、充電電流が、設定された第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、充電電流が、設定された第1の閾値よりも大きくかつピーク電流よりも小さく設定された第2の閾値を下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2の時間、充電電流が、設定された第1の閾値を下回ってから、第1の閾値を上回るまでの時間である第3の時間、の何れかの時間の回数や連続時間を用いて車種の判定を行う。【選択図】図12
