Document Type and Number:
WIPO Patent Application WO/2024/009185
Kind Code:
A1
Abstract:
Provided is a novel energy storage system. This system comprises a secondary battery and a differential stage. The differential stage is provided with a register; the differential stage functions to convert a first voltage of the secondary battery into first voltage data by analog-to-digital conversion; the differential stage functions to measure time required for the first voltage to change by a first voltage value; the register functions to hold second voltage data that is higher than the first voltage data by a data value that is equivalent to the first voltage value; and the differential stage functions to halt power supply to the register during an interval until the first voltage changes by the first voltage value.
