  • Patent number: 9620975
    Abstract: A battery characteristic converter comprises an interface to a battery and to an electronic device to be powered with energy supplied by the battery. The interface to the battery and the interface to the electronic device are connected using a bidirectional voltage ratio converter. The bidirectional voltage ratio converter is controlled so that the characteristics at the interface to the electronic device are adapted to the electronic device, independently of the battery characteristics. Energy may flow to the electronic device to power the electronic device or from the electronic device to the battery to charge the battery, depending on a comparison of the characteristics at the interfaces.
    Type: Grant

  • Patent number: 9118198
    Abstract: Systems and techniques for parallel battery balancing are described. A battery assembly comprises a first battery interface and a second battery interface; the first battery interface may connect to a first battery exhibiting a first voltage profile and the second battery interface may connect to a second battery exhibiting a second voltage profile. The battery assembly further comprises a current flow control mechanism to direct current flow to, from, and between the first battery and the second battery, with current directed to each battery being adapted so as to be compatible with the voltage profile of the battery.
