Application of Lifepo4 battery in energy storage system
UPS can provide energy to the load when the mains is abnormal or power outage, and it is widely used in communication, electric power, petroleum, finance and other industries. The energy storage system of UPS is usually lead-acid battery. However, lead-acid batteries not only have low energy density, large volume, large weight, and narrow temperature range, but also require high ambient temperature and pollute the environment. Lithium battery is the battery with the best performance at present. Using lithium battery as the energy storage device of UPS can greatly improve its performance. Therefore, based on lithium battery technology, this paper designs a set of lithium iron phosphate battery UPS system, which greatly improves the performance of UPS.
Application scenarios of lithium iron phosphate batteries in UPS
1. Industrial equipment
The UPS power supply floats the battery during normal time. When the industrial equipment suddenly loses power, the emergency power supply starts to work. When the mains returns to the power supply, the UPS battery returns to the floating state to ensure the necessary backup power supply capacity.Due to uncertain interference factors such as power failure, voltage sag and surge, continuous undervoltage and overvoltage, and frequency fluctuation during the supply of AC mains, these factors will affect the continuous operation of industrial equipment, and even affect the operation of industrial equipment. damage to the state of the device. Lithium battery UPS power supply has become a way to adjust voltage changes, eliminate various electrical disturbances, and provide high-quality power supply.
2. Communication base station
The power supply of the base station is introduced through the mains, and then converted into a 48V DC power supply through the inverter system of the UPS to supply power for the communication equipment. When the mains power is interrupted, the battery pack provides uninterrupted power supply to the base station to ensure the normal operation of the base station; when the mains power is restored, the UPS battery stops supplying power and restores the inverter function.
3. Data center
The data center must ensure the continuity of power supply and the safety of the power supply system. In the information center room of the data center, lithium battery UPS uninterruptible power supply is generally used as an important safety guarantee. UPS is a kind of uninterruptible power supply with energy storage device and inverter as the main component. When the mains power supply is interrupted, the UPS can ensure the continuity of the output power supply.
