Document Type and Number:
Japanese Patent JP7097336
Kind Code:
B2
Abstract:
A method of estimating the temperature of a secondary battery module comprises: a step for acquiring charging feature data including a current and a voltage supplied to the secondary battery module and a charging time during charging; and a step for estimating the temperature of a secondary battery constituting the secondary battery module by collating the charging feature data with correlation data between existing charging feature data stored in a database and the temperature. Accordingly, even when temperature information of the secondary battery constituting the secondary battery module cannot be obtained, the temperature of the secondary battery can be estimated.
