  • Patent number: 9735601
    Abstract: Systems and techniques are disclosed for individually controlling energy storage devices in an array of devices. An energy storage regulation unit (ESRU) is described that enables the connection of an energy storage device to a system load bus and a charging/diagnostic bus such that the energy storage device may be individually charged and/or disconnected for maintenance. The ESRU comprises switches for selectively connecting the system load bus circuit, charging circuit, or a bypass circuit. An energy storage regulator is further described for enabling the control of one or more ESRUs. A regulator controller may receive sensor or measurement data from the ESRUs connected to the energy storage regulator, and may also issue control instructions that control the switches of the individual ESRUs. Measurement data can include, for example, voltage, current, or temperature information relating to a specific ESRU.

  • Patent number: 9711979
    Abstract: In a power supply system using various kinds of storage batteries such as a large capacity storage battery or a small capacity storage battery, an electric power path is complicated, which may increase failures such as a short circuit trouble. There is a problem in that, when a short circuit trouble between storage batteries occurs, damage to a smaller capacity storage battery is serious. Accordingly, in a power supply system according to the present invention, the relationship among voltages, current capacities, and electric power capacities of various kinds of storage batteries such as a large capacity storage battery or a small capacity storage battery is defined so that damage to the storage batteries may be minimized even when malfunction occurs in, for example, switching a switch, and energy transfers from a higher voltage storage device.
