Publication number: 20230176134Abstract: An inspecting step includes a first period after a cooling step ends and a second period after the first period ends. Variations in a voltage drop value per unit time in a nonaqueous electrolyte rechargeable battery are smaller in the second period than in the first period. The cooling step cools the battery in a state where the electrode body is directly or indirectly pressurized and restrained in a thickness direction with a smaller pressure than that in the inspecting step or in a state where the electrode body is not restrained. The voltage value of the battery is measured when a specified time has passed after the voltage value of the battery was measured in the second period. The battery is determined as being normal when the voltage drop value per unit time based on the measured voltage value is less than or equal to a threshold value.Type: ApplicationFiled: November 30, 2022Publication date: June 8, 2023Applicants: PRIMEARTH EV ENERGY CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHA, PRIME PLANET ENERGY & SOLUTIONS, INC.Inventors: Shusaku GOTO, Hiroaki IKEDA
