ELECTRICAL STORAGE DEVICE AND ELECTRONIC CIRCUIT DEVICE USED FOR SAME

摘要

Provided are a battery, which can highly accurately detect the state of the battery, and an electronic circuit device used for the battery. The electronic circuit device has: a measuring section (121) which measures the voltage, current and temperature of a battery module (110); an operating section (122) which calculates the estimated values of the battery module (110) in the charged state and the degraded state, based on the measurement information obtained by the measurement performed by the measuring section (121); and a measurement parameter setting section (124) which sets parameters that indicate measurement conditions in the measuring section (121). The measurement parameter setting section (124) determines the state of a system wherein the battery module (110) is mounted as a power supply, and corresponding to the determined state of the system, the measurement parameter setting section sets measurement parameters.
