UPS as a core tool to ensure the operation of critical equipment, has been widely used in various industries. It is not only found in data centers, telecom base stations, but also in an increasing number of traditional industrial enterprises，For enterprises, how to maintain and manage UPS, in case of accidents, is crucial. When the mains power unexpectedly shut down, the UPS immediately start。
In general, the key components and performance of the UPS include static transfer switches, inverters, batteries, and ground performance. Multiple types of automatic power switches provide seamless power supply between the downstream power supplies of the UPS system, with power start-up times as fast as 4 milliseconds，The fast power supply process ensures the normal operation of the enterprise system and avoids economic losses。A normal battery will go through the cycle of use, deterioration, scrap. As the battery capacity gradually decreases, the internal resistance of the battery will change during the deterioration stage, and the battery voltage will only really show up when the battery is dead, too late。
When facing a battery with "good" voltage, engineers can already know what the battery resistance is, and lock the potential battery in advance to be more targeted。
In fact, battery management system (BMS) is a good solution. BMS are used to monitor key battery parameters such as internal resistance, voltage, temperature, leakage, and group current in real time to detect potential faults and send alarms to guide maintenance personnel to correct handling and avoid unnecessary accidents，The first time to understand the actual performance data of the battery, and can accurately assess the health of the battery, to obtain the effective basis for battery replacement and step use. It not only reduces the system risk of using battery, but also avoids unnecessary waste of resources。
