Patent number: 10135267Abstract: Provided is a secondary battery system capable of suppressing degradation of a battery capacity. When it is determined that a battery pack is brought into a non-use state, a battery state detection unit in a battery controller compares an SOC of the battery pack calculated by a battery state operation unit and a standard SOC. When the SOC of the battery pack is higher than the standard SOC, the battery state detection unit in the battery controller calculates a capacity value in which the SOC of the battery pack becomes lower than the standard SOC, from a difference of the SOC of the battery pack and the standard SOC, and transmits the calculated capacity value to a cell controller. The cell controller discharges the battery pack, on the basis of the capacity value transmitted from the battery state detection unit.Type: GrantFiled: May 28, 2014Date of Patent: November 20, 2018Assignee: Hitachi Automotive Systems, Ltd.Inventor: Hironori Sasaki

Patent number: 8994322Abstract: Since in existent charge-discharge control the battery direct current resistance of a lithium ion battery increases at a low temperature or in a low SOC, the battery voltage may possibly exceed greatly the maximum allowable voltage instantaneously due to over-voltage during charging or may possibly decrease greatly to less than the minimum allowable voltage during discharging. If the lithium ion battery continuously lies in such a state the battery performance is degraded abruptly. The battery resistance of a lithium ion battery module is estimated in accordance with SOC and temperature of the lithium ion battery module, and current to charge is set properly based on the estimated battery resistance.Type: GrantFiled: June 28, 2012Date of Patent: March 31, 2015Assignee: Hitachi, Ltd.Inventors: Hironori Sasaki, Tsunenori Yamamoto
