Abstract

A converter is to convert at least one of a first voltage output from a first energy storage device and a second voltage output from a second energy storage device. A detector is to detect the first voltage and a current flowing between the first energy storage device and the second energy storage device. Circuitry is configured to control the converter to perform a first constant current control in which a first constant current flows from one of the first energy storage device and the second energy storage device to another of the first energy storage device and the second energy storage device. The circuitry is configured to determine a state of the first energy storage device based on the first voltage and the first constant current while the first constant current control is performed.
