Abstract

To reduce the size and weight of a vehicle including a battery and a charger, which is not mounted on the vehicle, for charging the battery with a charging current supplied from a power source.

A vehicle 1 includes a battery 3 for discharging electricity to an electric motor 2 for driving the vehicle 1 to run. A charger 10 that is not mounted on the vehicle 1 is provided. The charger 10 can charge the battery 3 with a charging current supplied from a power source 8. At least one of the vehicle 1 and the charger 10 includes a charging storage device 18, 20 for storing charging history of the battery 3. The battery 3 is charged via the charger 10 based on the charging history stored in the charging storage device 18, 20.

Claims

1. A charging control device for a vehicle, the vehicle including a battery for discharging electricity to an electric motor for driving the vehicle to run, and a charger, which is not mounted on the vehicle, for charging the battery with a charging current supplied from a power source,

characterized in that at least one of the vehicle and the charger includes a charging storage device for storing charging history of the battery, so that the battery is charged via the charger based on the charging history stored in the charging storage device.

2. The charging control device for a vehicle according to claim 1, wherein a data signal representing the charging history stored in the charging storage device can be output to a display device to display the charging history on the display device.

3. The charging control device for a vehicle according to claim 1 or 2, wherein the vehicle is a golf cart.
