きる。In the battery charger for an electric vehicle having the above structure, the first charger 17 and the second charger 1 are used regardless of whether or not the night battery 15 is charged during the night time.
Both 8 use cheap night power. When the night battery 15 has charging power in the daytime, the night battery 15 is connected to the first battery charger 17 side which is in a position where it is easy to charge, and the second battery charger 18 is connected to the daytime battery power side. Therefore, the nighttime electric power charged in the night battery 15 is preferentially used when charging one electric vehicle, and the daytime electric power is used by the second charger 18 only when simultaneously charging two electric vehicles. To be done. Only when there is no charging power for the night battery 15 in the daytime,
Both the first charger 17 and the second charger 18 use daytime electric power. Therefore, the nighttime electric power is preferentially used in the nighttime period, the nighttime electric power stored in the nighttime is preferentially used in the daytime period, and only the daytime electric power is used only when the nighttime electric power is not stored. The battery can be charged at low cost by night power, the demand for leveling the power can be met, and the charging equipment at the service station can be efficiently used, so that the equipment can be miniaturized.

力の平準化の要請に対応できる効果がある。As described above, according to the present invention, the battery switching section selectively switches the switches for the daytime battery and the nighttime battery according to the charge amount and the operating time period and supplies them to the charger. In addition, the battery switching unit preferentially uses the night battery side during nighttime use and the nighttime battery side during nighttime use when the nighttime battery is charged, according to the output of the measurement control unit. If switched so, there is an effect that charging can be efficiently performed without waste and a request for leveling the power can be met.
