Abstract: A control method of a secondary battery in which malfunction is less likely to occur and abnormality detection can be performed with high accuracy is provided. A charge state estimation device of a secondary battery including a device which generates electromagnetic noise, a first detection means which measures a voltage value of a secondary battery electrically connected to the device, a second detection means which measures a current value of the secondary battery electrically connected to the device, a correction means which extracts a causal relationship between electromagnetic noise and a driving pattern from data including multiple electromagnetic noise obtained using the first detection means or the second detection means, and an arithmetic means which calculates a charge rate using a regression model based on data after data correction.

Abstract: A highly safe power storage system is provided. If n (n is an integer over or equal to three) secondary batteries are used in a vehicle such as an electric vehicle, a circuit configuration is used with which the condition of each secondary battery is monitored using an anomaly detection unit; and if an anomaly such as a micro-short circuit is detected, only the detected anomalous secondary battery is electrically separated from the charging system or the discharging system. At least one microcomputer monitors anomalies in n secondary batteries consecutively, selects the anomalous secondary battery or the detected secondary battery which causes an anomaly, and gives an instruction to bypass the secondary battery with each switch.
