20150035486 | CHARGE CONTROLLER FOR VEHICLE - An electric vehicle is able to be charged from a power source via a supply side controller. The supply side controller retrieves and acquires vehicular information from the electric vehicle as an electric connection is established with the electric vehicle. The supply side controller stores the retrieved vehicular information. The vehicular information may contain charging information used for a charging control and non-charging information not used for the charging control. An information device, such as a smart phone, requests to supply the vehicular information. In response to the request, the supply side controller supplies the stored vehicular information to the information device without accessing the battery charger and the vehicular functional device. Accordingly, it is possible to supply the vehicular information without rebooting the controller on the vehicle in response to the request from the information device. | 02-05-2015 |
