POWER SUPPLY APPARATUS AND CONTROLLING METHOD OF THE SAME
First Claim
1. A power supply comprising:
- a power supply circuit configured to receive a first power from an external power source, to receive a battery power, and to output a second power comprising at least one of the first power or the battery power to an external load; and
a battery pack coupled to the power supply circuit, the battery pack comprising a plurality of batteries, which are arranged into a plurality of battery groups comprising a first battery group and a second battery group, and configured to provide the battery power,wherein the battery pack is configured to selectively supply a power of the first battery group or a power of the second battery group as the battery power to the power supply circuit according to at least one of a status of the external power source, a status of the external load, a status of the first battery group, or a status of the second battery group.
