| titleOfInvention | Deterioration estimation device |
| abstract | PROBLEM TO BE SOLVED: To provide a technique for more accurately estimating a deteriorated state of a secondary battery. A deterioration estimation device disclosed here includes a map information storage unit, a resistance acquisition unit, and a deterioration state estimation unit. Here, the above map information is stored in a secondary battery for testing under a predetermined temperature environment of 70 ° C. or higher, or tested under predetermined conditions under a predetermined temperature environment of 70 ° C. or higher. The test secondary battery is energized, and during the storage or energization period, the test secondary battery has a predetermined SOC of 10% or more and 30% or less, and a predetermined temperature of 0 ° C. or less. It is based on the resistance value and battery capacity of the test secondary battery obtained by adjusting to the environment and measuring. In the map information, the resistance increase rate decreases with respect to the decrease in the capacity retention rate for a certain period from the storage of the test secondary battery or the start of the energization, and then the resistance increase rate increases. Trends are included. [Selection diagram] Fig. 1 |
