  • Patent number: 10286790
    Abstract: 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.

  • Patent number: 10291047
    Abstract: Systems and methods may place a battery in a first constant voltage charging mode and monitoring a diminishing current of the battery while the battery is in the first constant voltage charging mode. Additionally, the battery may be placed in a constant current charging mode when the diminishing current falls to a first predetermined threshold. In one example, a rising voltage of the battery is monitored while the battery is in the constant current charging mode and the battery is placed in a second constant voltage charging mode at an end of the charge cycle in response to the rising voltage reaching a second predetermined threshold. Moreover, a charge current corresponding to the constant current charging mode may be adjusted based on a charge capacity of the battery.
