Abstract: A converter is to convert at least one of a first voltage output from a first energy storage device and a second voltage output from a second energy storage device. A detector is to detect the first voltage and a current flowing between the first energy storage device and the second energy storage device. Circuitry is configured to control the converter to perform a first constant current control in which a first constant current flows from one of the first energy storage device and the second energy storage device to another of the first energy storage device and the second energy storage device. The circuitry is configured to determine a state of the first energy storage device based on the first voltage and the first constant current while the first constant current control is performed.

Abstract: A computer implemented method is provided. The method includes detecting, by a computer of a charging unit (CU), a connection of a charging connector of the CU to a vehicle charge port of an electric vehicle (EV). The detecting of the connection includes processing a data exchange between electronics of the EV and the computer of the CU. The method includes receiving, by the computer of the CU, charge status of the EV while the charging connector is connected to the CU. The received charge status of the EV changes as charge is provided from the CU to a battery of the EV. The method includes sending a notification by server to a user account that was used to obtain charge for the EV at the CU. The notification provides data for a graphical user interface that shows the charge status of the EV. The method includes receiving instructions from a device associated with the user account, to make payment of a fee or receive a fee charge, to instruct the CU to indicate an in progress or in-use state even when the EV is at a full level of charge while the EV is occupying the CU and is preventing others from access to the CU that is provided for public use of users with user accounts. The method includes sending data by the server to the computer of the CU to display an in progress or in-use state, wherein the server communicates over the internet with the device.

Abstract: A battery pack includes a plurality of rechargeable batteries, a sensor, and a battery manager. The sensor obtains motion information of the rechargeable batteries. The motion information includes at least one of first information obtained by sensing whether the rechargeable batteries are in a movement state or in a standstill state or second information on a state in which the rechargeable batteries are inclined. The second information may be obtained based on a change in angle when the rechargeable batteries are in the movement state. The battery manager control charging or discharging of the rechargeable batteries in a charge mode or a discharge mode based on the motion information.

Abstract: An electric vehicle includes a battery modules electrically connected in parallel and having the same nominal module voltage, a determination device for determining a battery state parameter representing a state of charge of the battery module; a switching system to switch current paths of the battery modules to be conducting or blocking; an energy management system configured to, if a battery module has a state of charge that is noticeably lower than a state of charge of another battery modules, switch the current path of the battery module with the lower state of charge to be blocking during a driving mode until the charging state of the battery module with the higher state of charge is balanced with the charge state of the battery module with the lower state of charge, and then switch the current path of the battery module with the lower state of charge to be conductive.
