What is the difference between UPS power supply and battery

UPS power supply is a kind of power supply equipment that can provide continuous, stable, and uninterrupted power. The most notable feature is that it can continuously output pure sine wave alternating current with zero interruption. When the mains grid is abnormal, it can also effectively purify the quality of mains, such as voltage mutation, voltage fluctuation, voltage drop, pulse interference, etc.

The battery is just one of the batteries, its function is to store the DC energy and release it to supply electricity when needed. The generation of batteries was originally based on the characteristics of alternating current, which could not be stored. The amount of power that the power plant sent every day had to be consumed. Even if it was not used up, it could not be recycled and reused, causing a lot of waste. The excess AC power is pumped and stored in a high-level reservoir, and is released to generate electricity again in the dry season or when the water volume is small in winter. Store it at the place and use it as a supplement when the water is insufficient. In fact, this is a helpless move. Later, with the development of DC technology and the emergence of batteries, people converted excess or specialized AC power into DC power and stored them in the battery for various purposes, such as emergency use in places where there is no power or no AC power. The application characteristics of direct current are also becoming more and more prominent, which is the reason why the application of batteries is becoming more and more extensive.
