Abstract:
An internal impedance of an electrical storage device is measured by using a signal of a frequency which ions in the electrical storage device are difficult to follow (e.g., a frequency equal to or higher than 10 kHz), and an internal temperature of the electrical storage device is calculated from a measured value of the internal impedance.
