  • Battery capacity estimation device, battery capacity estimation method, and computer program product
    Patent number: 11486931
    Abstract: A battery capacity estimation device in an embodiment includes one or more hardware processors configured to: acquire an alternating current power or an alternating current energy that is input to and output from a storage battery system via a direct current-alternating current converter, the storage battery system being capable of controlling charge and discharge; acquire a state of charge (SoC) of the storage battery system; and estimate a battery capacity of the storage battery system based on the acquired alternating current power or the acquired alternating current energy and the acquired SoC.
    Type: Grant
    Filed: July 23, 2020
    Date of Patent: November 1, 2022
    Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATION
    Inventors: Masako Kiuchi, Mami Mizutani, Kenji Mitsumoto, Noriyuki Yamagishi, Toshiyuki Seto, Kenichi Wakasugi
  • Reducer
    Patent number: 11131365
    Abstract: A reducer includes a fixed housing, a rotation housing, and multi-stage planetary gear mechanisms. The fixed housing contains a motor in the fixed housing. The rotation housing is rotatably supported by the fixed housing via a bearing at an outer surface of a one-end wall of the fixed housing. The multi-stage planetary gear mechanisms are configured to decelerate a rotation of the motor and transmit the rotation that has been decelerated to the rotation housing. The multi-stage planetary gear mechanisms include a final-stage planetary gear mechanism located at a downstream position in a direction in which motive power is transmitted. The final-stage planetary gear mechanism include a planetary gear rotatably supported by a planetary gear shaft that is supported at one end of the planetary gear shaft by the one-end wall of the fixed housing.
