Abstract

This application provides a method and a device for estimating a remaining charging time of a battery, and a battery management system. The method includes: determining a minimum charging time of each type of battery cell at a Kcharging phase based on a charge request current value of each type of battery cell at the Kcharging phase; and determining the remaining charging time of the battery when the Kcharging phase of any type of battery cell in the battery is a target state-of-charge phase, where the remaining charging time of the battery is a smallest one of accumulation values, each accumulation value being an accumulation of minimum charging times of a type of battery cell in the battery at all charging phases.
