How to operate a power storage device

Abstract

To reduce the power consumption of energy storage devices, or to provide energy storage devices with high safety. This enhances the safety of batteries monitored by semiconductor devices, or reduces power consumption. For example, reducing power consumption during hibernation, or the processing required to return from hibernation to normal operation. To reduce time or energy consumption. [Solution] The system comprises a battery, a control circuit, and a conversion circuit, the conversion circuit supplying voltage to the battery. The control circuit has the function of measuring the battery voltage data, and the battery voltage data A power storage device having the function of holding [something].

Claims

[Claim 1] It has a battery, a control circuit, and a conversion circuit. The control circuit comprises a processing unit including a processor core, a first sample-and-hold circuit, and a second sample-and-hold circuit. The first sample-and-hold circuit has a first transistor having an oxide semiconductor in the channel formation region, The second sample-and-hold circuit has a second transistor having an oxide semiconductor in the channel formation region, The processing apparatus is electrically connected to the gate of the first transistor and the gate of the second transistor, The processing unit provides signals to the gates of the first transistor and the second transistor, turning on the first transistor and the second transistor. The conversion circuit supplies voltage to the battery, The voltage data of the battery is supplied to one of the source and drain of the first transistor, and the current data of the battery is converted to a voltage and supplied to one of the source and drain of the second transistor. A method for operating an energy storage device, wherein the processing device supplies signals to the gates of the first transistor and the second transistor, thereby turning off the first transistor and the second transistor.
