Patent number: 11221367Abstract: According to one embodiment, an evaluation device includes first processing circuitry and second processing circuitry. The first processing circuitry calculates a feature value of an energy storage device based on voltage values measured from the energy storage device being subjected to charge-discharge-control according to charge-discharge command values. The second processing circuitry derives an evaluation function of a degradation state of the energy storage device according to a difference between a distribution of the charge-discharge command values and a reference distribution. The second processing circuitry evaluates the degradation state of the energy storage device, based on the evaluation function and the calculated feature value.Type: GrantFiled: September 11, 2019Date of Patent: January 11, 2022Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Takahiro Yamamoto, Hisaaki Hatano, Masatake Sakuma, Kenichi Fujiwara, Takenori Kobayashi, Tomohiro Toyosaki, Yoshiyuki Sakamoto

Patent number: 10205335Abstract: According to one embodiment, a storage battery management device includes a chargeable/dischargeable capacity table, a controller, and a communication controller. The chargeable/dischargeable capacity table stores therein in advance a chargeable/dischargeable capacity corresponding to a temperature, a state of charge (SOC), a required charge rate or discharge rate, and a battery degradation rate of a secondary battery. The controller calculates an actual chargeable/dischargeable capacity by referring to the chargeable/dischargeable capacity table based on the temperature, the SOC, the required charge rate or discharge rate, and the battery degradation rate of the secondary battery. The communication controller informs a host device about the chargeable/dischargeable capacity of the secondary battery.Type: GrantFiled: February 24, 2015Date of Patent: February 12, 2019Assignee: Kabushiki Kaisha ToshibaInventors: Yasuji Sakata, Mami Mizutani, Takenori Kobayashi, Tomohiro Toyosaki
