POWER SUPPLY APPARATUS
First Claim
1. A power supply apparatus comprising:
- a rechargeable battery; and
a battery management system (BMS) for managing charging and discharging of the battery,wherein the power supply apparatus is configured tosupply an operating power to the BMS from an external power of an external power source when the external power source is in a normal state and is capable of supplying the external power to a load through the power supply apparatus, andsupply the operating power to the BMS from electric energy stored in the battery when the external power source is in a state different from the normal state and is not capable of supplying the external power to the load through the power supply apparatus.

Abstract
A power supply apparatus is disclosed. The power supply apparatus includes a rechargeable battery and a battery management system (BMS) for managing charging and discharging of the battery. The power supply apparatus is configured to supply an operating power to the BMS from an external power of an external power source when the external power source is in a normal state and is capable of supplying the external power to a load through the power supply apparatus. The power supply apparatus is further configured to supply the operating power to the BMS from electric energy stored in the battery when the external power source is in a state different from the normal state and not capable of supplying the external power to the load through the power supply apparatus.
