Abstract
A battery state is estimated with high accuracy from battery data including a large amount of missing section. In a battery analysis system, a data acquisition unit acquires battery data of a secondary battery from at least one apparatus (for example, an electric car or a charging stand) via a network. A log type determination unit chronologically classifies acquired battery data including a log missing section of a specific secondary battery into a log section of even charge and discharge, a log section of excessive charge, and a log section of excessive discharge.
Claims12
A battery analysis system comprising:
- a data acquisition unit configured to acquire, from at least one apparatus via a network, battery data items of a secondary battery in the at least one apparatus;
- and
- a log type determination unit configured to, when the battery data items obtained by the data acquisition unit include a log missing section, chronologically classify each of the battery data items into any of a log section of even charge and discharge, a log section of excessive charge, and a log section of excessive discharge.
A battery analysis method comprising:
- a step of acquiring, from at least one apparatus via a network, battery data items of a secondary battery in the at least one apparatus;
- and
- a step of, when the battery data items include a log missing section, chronologically classifying each of the battery data items into any of a log section of even charge and discharge, a log section of excessive charge, and a log section of excessive discharge.
A battery analysis program that causes a computer to perform types of processing below:
- processing of acquiring, from at least one apparatus via a network, battery data items of a secondary battery in the at least one apparatus;
- and
- processing of, when the battery data items include the log missing section, chronologically classifying each of the battery data items into any of a log section of even charge and discharge, a log section of excessive charge, and a log section of excessive discharge.
