Patent number: 10605871Abstract: A method for determining a state of a rechargeable battery includes obtaining a complex impedance measured by applying AC voltage or AC current to a rechargeable battery that is subject to determination and determining a state of the rechargeable battery based on the obtained complex impedance. The determining a state of the rechargeable battery includes determining whether or not a first capacity shift is occurring based on a comparison of a value of the complex impedance at a predetermined frequency with a first determination value used to determine a negative electrode capacity shift, and when determined that the first capacity shift is not occurring, determining whether or not a second capacity shift is occurring based on a comparison of a gradient of the complex impedance with respect to a real axis in a diffusion resistance region with a second determination value used to determine a positive electrode capacity shift.Type: GrantFiled: September 6, 2018Date of Patent: March 31, 2020Assignees: PRIMEARTH EV ENERGY CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroshi Matsuno, Shinichiro Ito, Yasushi Nakagiri, Daisuke Koba, Tamotsu Fukuma, Junta Izumi, Kazuya Kodama, Masahiko Mitsui
