1. A method of discharging a battery assembly used to power at least part of an object, the method comprising:
detecting, with aid of one or more processors, when power to the object is turned off;
detecting, with aid of a timer, an amount of time elapsed since the power to the object is turned off;
initiating, with aid of the one or more processors, a controlled self-discharge of the battery assembly when the amount of time exceeds a threshold length of time, wherein the controlled self-discharge of the battery assembly is performed by a self-discharging circuit electrically coupled to the battery assembly;
terminating, with aid of the one or more processors, the controlled self-discharge of the battery assembly when the voltage reaches a threshold voltage value; and
controlling, with aid of the one or more processors, the battery assembly to enter a hibernation mode subsequent to terminating the controlled self-discharge of the battery assembly, wherein the hibernation mode is a low power consumption mode monitoring whether the battery assembly is in use again.
