Abstract

A method of discharging a battery assembly includes detecting, with aid of a timer, when the battery assembly is not in use for a threshold length of time, where the battery assembly is configured to power at least a part of a movable object. The method further includes initiating a controlled self-discharge of the battery assembly when the battery assembly is not in use for the threshold length of time; and during the controlled self-discharge of the battery assembly, in response to detecting that the battery assembly is activated or detecting that the movable object is powered on or detecting that current is flowing from the battery assembly, terminating the controlled self-discharge of the battery assembly regardless whether the battery assembly voltage drops to a threshold voltage value.
