Method and apparatus for testing battery conditions
First Claim
1. A method of testing a battery of a device, comprising:
- receiving a testing command for the battery;
in response to receiving the testing command, causing the battery to enter into a testing mode in which the battery and a power supply of the device concurrently provide power to the device, a first voltage provided by the battery being greater than a second voltage provided by the power supply and a first current provided by the battery being less than a second current provided by the power supply; and
determining a condition of the battery by monitoring current outputted by the battery, wherein determining the condition of the battery comprises;
determining that the first current is in a range limited by a lower-limit threshold current and an upper-limit threshold current, andin response to the first current being above the upper-limit threshold current, adjusting the first current to be in the range by lowering the first voltage while keeping the first voltage above the second voltage.

Abstract
Embodiments of the present disclosure provide a method and apparatus for testing a condition of a battery. In one embodiment, a testing instruction for the battery is received from a controller of a device. In response to reception of the instruction, the battery is caused in a testing mode in which the battery and a power supply of the device concurrently provide power to the device, a first voltage provided by the battery being greater than a second voltage provided by the power supply. A condition of the battery is determined by monitoring an output current of the battery. Through the method and apparatus of the embodiments of the present disclosure, consumption for battery test may be reduced without a need of interrupting operations of the apparatus.
