  • Publication number: 20250052823
    Abstract: In a battery abnormality detection system, a data acquirer acquires a current flowing through a battery and a temperature of the battery. A determiner determines presence or absence of abnormal heat generation of the battery based on a relation between an amount of the current flowing through the battery in a certain period and a temperature rise of the battery in the certain period. The determiner determines the presence or absence of the abnormal heat generation of the battery based on the current and the temperature of the battery in a charging period in which the temperature of the battery exceeds a set temperature.

  • Patent number: 12196812
    Abstract: When a use range of an SOC (State Of Charge) of a secondary battery is expanded, the use range of the SOC is expanded by increasing an upper limit value or decreasing a lower limit value of the use range of the SOC. The increasing the upper limit value or decreasing the lower limit value of the use range of the SOC is determined to a side causing a smaller increase in a degradation rate of the secondary battery, based on at least one of a cycle degradation characteristic that defines a cycle degradation rate in accordance with the use range of the SOC and a current rate of the secondary battery and a storage degradation characteristic that defines a storage degradation rate in accordance with the SOC and a temperature of the secondary battery, and a typical use condition of the secondary battery based on a use history of the secondary battery.

  • Publication number: 20230391221
    Abstract: A path finder sets a plurality of nodes in a state of charge (SOC) zone that is between a target SOC, which is set when a secondary battery provided in an electric moving body is charged, and a present SOC, and sets a plurality of nodes in a chargeable time period that is between a charging start time and a charging end time. A cost assigner refers to at least one of storage degradation characteristics, charge cycle degradation characteristics, or a time-of-use electricity fee table to assign a cost of a degradation amount or an electricity fee to each path between nodes. The path finder finds the charging path that minimizes a total cost of the paths between the nodes. A charging plan creator creates a charging plan based on the charging path found.
