　　6. There is no memory effect. No matter what state the lithium iron phosphate battery is in, it can be charged and used at any time. There is no need to discharge it completely before charging.

　　7. Market advantages. The lithium battery UPS market has begun to take shape in the country (accounting for more than 65% of the international market). The withdrawal of lead-acid batteries from the historical stage has created unparalleled opportunities for the development of environmentally friendly lithium power sources. Electric vehicle battery replacement has emerged in various places. It is expected that lithium battery UPS power supply will explode in the next two years and become a giant in the battery industry.

　　The main application scenarios of lithium batteries in UPS power supplies:

　　1. Industrial equipment

　　When the UPS power supply is in normal operation, the lithium battery is float-charged. When the industrial equipment suddenly loses power, the emergency power supply starts working. When the mains power is restored, the UPS battery returns to the float-charge state to ensure the necessary backup power supply capability. During the AC power supply process, there may be uncertain interference factors such as power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations. These factors will affect the continuous operation of industrial equipment and even affect the operation of industrial equipment. equipment causing damage. Lithium battery UPS power supply has become a way to adjust voltage changes, eliminate various electrical interference, and provide high-quality power supply.

　　2. Communication base station

　　The power supply of the communication base station is introduced through the mains power, and then converted into 48V DC power supply through the rectification system to power the communication equipment. When the mains power is interrupted, the lithium battery pack supplies uninterrupted power to the base station to ensure normal operation of the base station; when the mains power is restored, the UPS lithium battery stops supplying power and is powered by the mains power.

　　3. Data center

　　The data center must ensure the continuity of power supply and the safety of the power supply system. UPS power supply is generally used in the information center computer room of the data center as an important safety guarantee. UPS is an uninterruptible power supply that contains an energy storage device and is composed of an inverter as the main part with stable voltage and frequency. When the mains power supply is interrupted, the lithium battery UPS can ensure the continuity of the output power supply. Lithium battery is a key component of the UPS power system. As the final guarantee of power supply, the lithium battery pack is undoubtedly the last insurance in the UPS power supply. It needs to be maintained and managed. Its condition is directly related to whether the UPS in the data center is normal or not. Work.

　　4. Computer room system integration

　　The power supply and distribution system of computer room equipment has very high power supply quality requirements. Lithium battery UPS uninterruptible power supply should be used to ensure the stability and reliability of power supply. The power supply of the auxiliary power supply and distribution system is directly supplied by the city power. Compared with traditional batteries, the use of lithium battery UPS power supply can greatly improve the quality of power supply. The power supply will not be interrupted when the power is switched, nor will there be strong arc interference. The computer will not lose information and data, and it protects computer equipment, especially the hard drive, from scratches caused by power outages.

　　5. Special modified vehicles

　　The communication command vehicle uses advanced high-power broadcast command system, modern wireless communication technology, computer technology, image acquisition and transmission technology, strong light lighting technology, etc. to realize communication between the command vehicle and on-site staff, on-site command and dispatching and other functions. It is a command center for large-scale scenes, mass evacuation, rescue and comprehensive movement for public security, fire protection and other departments.
