Description

technical field

[0001] The present invention relates to an electric device such as an electric vehicle such as an electric two-wheeled vehicle or an electric wheelchair using electric energy of a battery as a power source, a charging device for charging the battery unit thereof, and a method for charging and discharging the battery unit. Background technique

[0002] Like an electric two-wheeled vehicle or an electric wheelchair, there is an electric vehicle equipped with a storage battery pack composed of a plurality of storage batteries as a power source. Among such electric vehicles, there are vehicles that drive the electric motor with electric energy (electric power) from a mounted battery pack and run only by the driving force, or vehicles that run by the combined force of the driving force of the electric motor and human power, or A vehicle, etc. that switches between the driving force of the gasoline engine and the driving force of the electric motor.
