Abstract

An electric vehicle is disclosed. The battery unit of the electric vehicle comprises a stationary battery and a removable battery which needs to be exchanged at a battery exchange station. Temporary power shortage problems caused by power supply through a single stationary battery or a single removable battery are solved by power supply through each of or both of the stationary battery and the removable battery.

Claims

1. An electric vehicle, comprising a battery unit, wherein the battery unit includes

a stationary battery installed in the electric vehicle and directly charged in the electric vehicle by a power source connected with the electric vehicle;

and

a removable battery installed in the electric vehicle and replaced with a fully-charged removable battery in a battery exchange station.

2. The electric vehicle according to claim 1 whose battery unit includes a plurality of removable batteries.

3. The electric vehicle according to claim 2, wherein the battery unit is electrically connected with a residual capacity display device, and wherein the residual capacity display unit further includes a first residual capacity display device electrically connected with the stationary battery and a second residual capacity display device electrically connected with the removable battery.

4. The electric vehicle according to claim 3, wherein a switching module is electrically connected with the stationary battery and a removable battery, and wherein the switching module is a switch selectively switching the stationary battery, the removable battery, or both of the stationary battery and the removable battery to power the electric vehicle.

5. The electric vehicle according to claim 4, wherein a charging jack is electrically connected with the stationary battery.

6. The electric vehicle according to claim 5, wherein the first residual capacity display device and the second residual capacity display device are liquid crystal display devices, light emitting diode display devices, or indicator devices.
