Document Type and Number:
WIPO Patent Application WO/2022/154441
Kind Code:
A1
Abstract:
A battery management device, according to one embodiment of the present invention, comprises: a measurement unit for measuring, for every cycle, the voltage of a battery after discharging of the battery ends at a preset discharge end voltage; and a control unit for receiving, for every cycle, voltage information about the battery from the measurement unit, calculating a first voltage deviation of the battery on the basis of a preset first reference voltage and the voltage of the battery, calculating, at each cycle, a second voltage deviation between the first voltage deviation and a preset second reference voltage, and adjusting the discharge end voltage on the basis of a reference deviation set to correspond to the current cycle and the second voltage deviation calculated in the current cycle.
