Document Type and Number:
WIPO Patent Application WO/2022/201913
Kind Code:
A1
Abstract:
This battery device comprises a storage unit, a calculation unit, a level shifter, and an A-D conversion unit. The storage unit stores battery information including the closed circuit voltage of a plurality of battery cells that are electrically connected. The calculation unit sets an acquisition range for closed circuit voltage on the basis of the battery information. The level shifter and the A-D conversion unit convert closed circuit voltage into a digital signal, in the acquisition range set by the calculation unit. If the closed circuit voltage is outside the acquisition range, the calculation unit changes the acquisition range.
