きる。In the battery charger for an electric vehicle having the above-described structure, the first charger 17 and the second charger 1 can be used at night regardless of whether or not the battery 15 has a charge.
8 both use inexpensive nighttime electricity. Also, when there is charging power for the night battery 15 during the daytime, the night battery 15 is connected to the first charger 17 located at a position where charging is easy, and the second charger 18 is connected to the day power. Therefore, when charging one electric vehicle, the nighttime power charged in the night battery 15 is preferentially used, and only when charging two electric vehicles at the same time, the daytime power is used by the second charger 18. Is done. Only when there is no charging power for the night battery 15 during the daytime,
Both the first charger 17 and the second charger 18 use daytime power. Therefore, nighttime power is used preferentially during nighttime, nighttime power stored at nighttime is used preferentially during daytime, and only daytime power is used only when there is no nighttime power storage. In addition to being able to charge the battery at low cost with nighttime power, it is possible to meet the demand for power leveling, and the charging equipment at the service station can be used efficiently, and the equipment can be downsized.

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 unit selectively supplies the daytime battery and the nighttime battery to the charger by selectively switching the switches according to the charge amount and the use time zone. In addition, the battery switching unit uses the output of the measurement control unit to preferentially use the night battery during night use and the night battery when there is a storage amount of the night battery during day use. Such switching has an effect that charging can be efficiently performed without waste, and a request for power leveling can be met.
