Abstract

An electric vehicle equipped with an automotive battery. The automotive battery has a charging unit on the left side surface, discharging units on the right side surface, and a battery-side power supply terminal on the lower surface. The automotive battery drives an electric motor when the vehicle is moving, supplies power to external electrical products when the vehicle is not moving, and is configured so as to be usable at all times.

Claims

1. An electric vehicle including a vehicle body, an on-board battery mounted on the vehicle body, and an electric motor supplied with an electric power from the on-board battery, the electric vehicle being driven by the electric motor to travel,

wherein the vehicle body includes a battery receiving portion for releasably receiving the on-board battery, the battery receiving portion having vehicle-body-side feeding terminals disposed on a bottom thereof for supplying an electric power of the on-board battery to a vehicle body side,

wherein the on-board battery has battery-side feeding terminals disposed on a bottom surface thereof for mating with the vehicle-body-side feeding terminals of the battery receiving portion, wherein the on-board battery has a charge portion disposed on one lateral surface thereof for allowing an external power supply to charge the on-board battery, the one lateral surface facing one of left and right sides of the vehicle body, wherein the on-board battery has a discharge portion disposed on an opposite lateral surface for supplying an electric power of the on-board battery to an outside, the opposite lateral surface facing the other of the left and right sides of the vehicle body, and wherein the on-board battery has a transformer incorporated therein for transforming an electric power and/or converting a DC to an AC, and

wherein the vehicle body includes lateral surfaces having a charge side opening for allowing a plug or a connector to pass through the charge side opening into connection to the charge portion, and a discharge side opening for allowing a plug or a connector to pass through the discharge side opening into connection to the discharge portion.

2. The vehicle of claim 1, wherein the on-board battery has a raised or recessed portion formed on a surface thereof, and the battery receiving portion has a recessed or raised guide for guiding the raised or recessed portion of the on-board battery.

3. The vehicle of claim 1, wherein the battery receiving portion is provided with a locking mechanism for preventing the on-board battery received in the battery receiving portion from coming out of the battery receiving portion.

4. The vehicle of claim 1, wherein the vehicle-body-side feeding terminals protrude upwardly from the bottom of the battery receiving portion.

5. The vehicle of claim 1, wherein the charge side opening and the discharge side opening are closed by lids each movable between an open position and a closed position.

6. The vehicle of claim 3, wherein the vehicle body further includes a receptacle disposed behind the battery receiving portion and the receptacle receives an operational lever of the locking mechanism.

7. The vehicle of claim 1, wherein the bottom of the battery receiving portion has a drainage port formed therethrough.

8. The vehicle of claim 2, wherein the battery receiving portion is provided with a locking mechanism for preventing the on-board battery received in the battery receiving portion from coming out of the battery receiving portion.
