Patent number: 11047917Abstract: A power supply system is provided with a secondary battery, a memory unit, a calculation unit and a SOC characteristics acquiring unit. The memory unit stores initial characteristics data having a relationship between the open circuit voltage and the capacity for the secondary battery before being deteriorated. The calculation unit utilizes the initial characteristics data to calculate a deteriorated characteristics data which is a relationship between the open circuit voltage and the capacity of the deteriorated secondary battery. The SOC characteristics acquiring unit acquires the relationship between the open circuit voltage and the state of charge of the deteriorated secondary battery by dividing the capacity value included in the deteriorated characteristics data by the fully charged capacity of the deteriorated secondary battery.Type: GrantFiled: September 3, 2019Date of Patent: June 29, 2021Assignee: DENSO CORPORATIONInventors: Yoshikazu Kusano, Koji Ohira

Patent number: 10901040Abstract: A battery state estimating device periodically estimates a battery state of a secondary battery. The battery state estimating device has a current amount acquiring section, a threshold amount memory, a current amount comparing section, a cycle setting section, and a battery state estimating section. The current amount acquiring section acquires a current amount flowing in the secondary battery. At least one current threshold amount is stored in advance in the threshold amount memory. The current amount comparing section compares the current amount acquired by the current amount acquiring section with the current threshold amount stored in the threshold amount memory. The cycle setting section sets an estimation cycle for estimating the state of the secondary battery based on this comparison result. The battery state estimating section periodically estimates the battery state of the secondary battery based on the estimation cycle set by the cycle setting section.Type: GrantFiled: March 14, 2018Date of Patent: January 26, 2021Assignee: DENSO CORPORATIONInventors: Yoshikazu Kusano, Koji Ohira, Naomi Awano
