Abstract: A method for determining a remaining charging time of a battery. The method includes obtaining a first charging current and a second charging current. The first charging current is a present charging current of the battery, and the second charging current is a charging current of the battery when the battery is fully charged. The method further includes determining an average charging current value based on the first charging current and the second charging current, and determining the remaining charging time based on the average charging current value.
