What is UPS battery (Uninterrupted Power Supply)

UPS battery (Uninterrupted Power Supply) refers to the device which could provide short-term power supply in the event of sudden power failure to prevent damage to the back-end equipment and cause losses. The UPS mainly relies on the battery to discharge.

According to the business manager of Better Technology Group Limited, in the UPS power supply system, most of the batteries are maintenance-free batteries. The main function of the maintenance-free battery in the UPS power supply system is to store electrical energy. Once the mains power is interrupted, the battery will be discharged to supply the inverter, and the inverter will convert the DC power released by the battery into sinusoidal AC power to maintain the power output of the UPS and ensure the load consumes electricity normally within a certain period of time.

When the mains supply is normal, the battery stores electric energy in the rectifier-charging circuit, and at the same time it plays the role of smoothing and filtering the DC circuit, and acts as a buffer when the inverter is overloaded.

Its functions mainly include two aspects: to achieve the continuity of power supply when the power supply of mains and diesel generators fluctuates, interruptes instantaneously or even interrupts. In the process of seamless switching of the power supply, it can ensure that the power supply to the device will not be interrupted for more than 10mins, and ensure that the device will not lose power.

After the power supply of the mains and oil generators is interrupted, it is used as a backup energy for a limited time to ensure that the load can use electricity normally within a certain period of time. It is the last energy guarantee for the emergency power supply of the AC UPS system, and its role mainly depends on the discharge current and capacity of the maintenance-free battery pack.

In daily work, people tend to think that maintenance-free batteries are maintenance-free without paying attention. However, due to the unreasonable use of the battery, problems such as electrolyte drying, thermal runaway, early capacity loss, and internal short circuit of the battery have occurred, which seriously affect the reliability of the power supply system. Some data show that the proportion of UPS host failure or abnormal operation caused by battery failure is about 60%. It can be seen that the correct use and maintenance of UPS batteries has an increasingly important significance for extending the service life of maintenance-free batteries and reducing the failure rate of UPS power supply systems. At present, UPS emergency power supply, as a backup power supply, plays an important role when the grid voltage is interrupted and has become an indispensable part of our life.
