Title:

BATTERY MANAGEMENT DEVICE, BATTERY MANAGEMENT METHOD, AND BATTERY PACK

Document Type and Number:

WIPO Patent Application WO/2020/153637

Kind Code:

A1

Abstract:

Provided are a battery management device, a battery management method, and a battery pack. The battery management device generates a first data set including a first current value, a first voltage value, and a first temperature value which represent the current, voltage, and temperature of a battery. The battery management device generates a second data set from the first data set by using an error generator. The battery management device determines a first candidate value, a second candidate value, and a third candidate value with respect to a state of charge, from each of the first current value, the first data set, and the second data set. If a second difference value between the first candidate value and the third candidate value is less than a first difference value between the first candidate value and the second candidate value, a control unit updates a correction value.
