Abstract

A system for recording a charging history of a battery is mounted on a hybrid vehicle or an electric vehicle. The battery is charged from an outside power source through a plug. The recording system includes a receiver for receiving signals from satellites of a global positioning system, a memory medium and a display device. Every time the battery is charged, a position where the battery is charged is recorded in the memory medium. The position is detected based on the signals from the satellites. A date and time when the battery is charged may be included in the charging-history. The recorded charging history is read-out from the memory medium upon request and displayed on the display device. Thus, the past charging-history is traced. The charging-history may be transmitted to an outside server located at a police station or a charging-service provider to prevent power stealing or to improve services.

Claims

1. A system for recording charging-history of a battery that is rechargeable from an outside power source and supplies electric power to an electric motor for driving an automotive vehicle, the system comprising:

a position detector for detecting a present position of the vehicle;

means for determining whether the battery has been charged; and

means for recording the charging history of the battery, wherein the recording means records the present position of the vehicle where the battery is charged when the determining means determines that the battery has been charged.

2. The recording system as in claim 1, further including means for detecting a date and time, wherein the recording means further records the date and time when the battery is charged when the determining means determines that the battery has been charged.

3. The recording system as in claim 1, wherein:

the position detector includes a receiver for receiving signals from satellites of a global positioning system; and

the present position of the vehicle is detected based on the signals.

4. The recording system as in claim 2, wherein:

the position detector includes a receiver for receiving signals from satellites of a global positioning system; and

the date and time when the battery is charged is detected from the signals.

5. The recording system as in claim 1, further including a display device for displaying information and means for finding whether a request for reading-out the charging history recorded in the recording means is inputted, wherein the charging history is read-out and displayed on the display device when the request for reading-out is inputted.

6. The recording system as in claim 1, further including means for communicating with outside devices, wherein the charging-history recorded in the recording means is read-out and transmitted to the outside devices through the communicating means when a request for transmitting the charging-history is inputted.

7. The recording system as in claim 1, further including means for communicating with outside devices, wherein, when a new record of the charging-history is added to the recording means, the new record is automatically transmitted to the outside devices through the communicating means.
