Emergency power supplies, as the name suggests, are devices that provide electrical energy in emergency situations. They typically serve as backup power, quickly activated when the main power source fails or malfunctions to ensure the continuous operation of critical equipment or systems.
Energy storage power supplies, on the other hand, are devices capable of storing electrical energy and releasing it when needed. They can not only serve as backup power but also charge during off-peak hours and discharge during peak hours, thus balancing grid load and improving energy efficiency.
