Title:
POWER STORAGE DEVICE AND METHOD FOR OPERATING POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/084368
Kind Code:
A1
Abstract:
The power consumption of a power storage device is reduced. A safe power storage device is provided. Furthermore, the safety of a battery monitored by a semiconductor device is improved. Moreover, power consumption, for example, power in a dormant state is reduced. Furthermore, a time or energy for processing for returning to a normal state from a dormant state is reduced. Provided is a power storage device comprising the battery, a control circuit, and a converter circuit. The converter circuit has the function of applying a voltage to the battery. The control circuit has the function of measuring data on the battery voltage and the function of holding the data on the battery voltage.
