Abstract

A data collection system that collects information indicating a status of a battery mounted on a vehicle from the vehicle after shipment from a factory, includes a battery information collection server that is configured to periodically receive information of the battery and identification information, with which it is possible to identify the vehicle, that are transmitted wirelessly from a computer that is mounted on the vehicle and is configured to acquire and store the information of the battery mounted on the vehicle. The data collection system may further include a battery information analysis section that is configured to display a result of associating the information of the battery received by the battery information collection server with each vehicle using the identification information.

Claims

1. A data collection method of collecting information indicating a status of a battery mounted on a vehicle from the vehicle after shipment from a factory, comprising:

acquiring and storing the information of the battery mounted on the vehicle in a computer of the vehicle; and

periodically transmitting the information of the battery stored in the computer from the vehicle to a battery information collection server wirelessly.

2. The data collection method according to claim 1, wherein

when the information of the battery is transmitted, identification information, with which it is possible to identify the vehicle, and the information of the battery are transmitted to the battery information collection server, and

the data collection method further includes storing, in the battery information collection server, the information of the battery in association with the vehicle using the identification information.

3. The data collection method according to claim 2, wherein

the identification information is stored in a battery monitoring control unit incorporated into a battery pack having the battery, and

when the information of the battery is transmitted, the identification information and battery information, in which variation in the status of the battery during a specified period is recorded, are read from the battery monitoring control unit and transmitted to the battery information collection server.

4. The data collection method according to claim 3, further comprising;

referring to the identification information, the information of the battery corresponding to the identification information, replacement history of the battery monitoring control unit, and replacement history of the battery incorporated into the battery pack, to extract the information of the battery corresponding to the battery monitoring control unit; and

processing and displaying the extracted information.

5. A data collection system that collects information indicating a status of a battery mounted on a vehicle from the vehicle after shipment from a factory, comprising:

a battery information collection server that is configured to periodically receive information of the battery and identification information, with which it is possible to identify the vehicle, that are transmitted wirelessly from a computer that is mounted on the vehicle and is configured to acquire and store the information of the battery mounted on the vehicle.

6. The data collection system according to claim 5, wherein

the battery information collection server is configured to store the information of the battery in association with the vehicle using the identification information.

7. The data collection system according to claim 5, further comprising

a battery information analysis section that is configured to display a result of associating the information of the battery received by the battery information collection server with each vehicle using the identification information.

8. The data collection system according to claim 7, wherein

the vehicle is equipped with a battery pack including the battery and a battery monitoring control unit that is configured to monitor the battery;

and

the battery information analysis section is configured to refer to the identification information, the information of the battery corresponding to the identification information, replacement history of the battery monitoring control unit, and replacement history of the battery incorporated into the battery pack, to extract the information of the battery corresponding to the battery monitoring control unit, and process and display the extracted information.
