Characteristics of lithium battery pack

The impact of lithium battery packs on high-speed rail: At this stage, the world's first new energy technology air rail processing line has already been put into trial operation in Chengdu. According to reports, the design method for this air-to-rail detection connection line is at a speed of 60 kilometers per hour, a carriage is 18 meters long, 20 meters wide, and has a capacity of 120 people. The total length of the test route is 1461 meters. All test system software consists of the tourist station, the main track prefabricated box girder (including bridge piles), the right track prefabricated box girder (including bridge piles), and the turning section (the minimum road turning radius is 30 Meters), up and down slopes (maximum inclination 60‰), passenger car compartment, static regulation storage (charging head), high-power lithium battery battery pack and other modules. It means that our country has become the third country to master the technology of dual-track transportation suspension after France and Japan. In addition, because this test route uses lithium battery packs instead of high-voltage towers for suspension train traction belts for the first time in the world today, it has a completely independent patent in the relevant technology in my country. It is a major independent innovation in my country's urban rail industry. Why do air irons use lithium battery packs, and what characteristics of lithium battery packs make air iron interior designers choose it, let us discuss the advantages of lithium battery packs below. Characteristics of lithium battery packs: 1. Specific energy: Under the same volume, the specific energy of lithium batteries is 3 to 4 times higher than that of lead-acid batteries, twice as high as nickel-cadmium batteries, and twice as high as nickel-hydrogen rechargeable batteries. If the battery power is the same, the lithium battery will be smaller and lighter than the lead-acid battery, nickel-cadmium battery and nickel-hydrogen rechargeable battery. 2. Long life: The cycle time of lead-acid battery is about 300 times. However, the power lithium battery of a lithium iron phosphate battery charged at 1C at room temperature has a single volume of more than 80% after 2000 cycles, and the service life of the 3C cycle system reaches more than 800 times. Lead-acid batteries have very high requirements for working temperature. When the working temperature is high, their service life does not exceed five years. Under the same standard, the service life of the lithium iron phosphate battery rechargeable battery is longer. 3. Excellent high temperature characteristics: The maximum value of lithium iron phosphate electric heating reaches 350~500℃, and the operating temperature range is wide (-20~+75℃), and it can still release 100% of the volume at high temperature (60℃). 4. Polymer battery charging and discharging: The charging and discharging curve of the lithium iron phosphate battery rechargeable battery on the graph can still achieve 90% even when the charging and discharging ratio is 4C. 5. Fast charging: fast charging and charging and discharging can be a large current of 2C, and the battery can be charged in 40 minutes under the special charging head to fill the rechargeable battery, and the starting current can reach 2C, while the lead-acid battery does not have this kind of characteristics at this stage . 6. Safety: Safety comes from the reliability of battery cathode materials and reliable safety factor design methods. Lithium iron phosphate batteries thoroughly deal with the safety risks of lithium cobalt oxide and lithium iron phosphate. Lithium cobalt oxide and lithium iron phosphate are strong The impact will cause ***, and the lithium iron phosphate battery has long been based on rigorous safety detection, even in a strong impact, it will not cause ***. 7. Ecological and environmental protection: The raw materials of lithium iron phosphate battery do not have all heavy metals and non-ferrous metals. No matter whether it is processed or used, it has zero pollution and conforms to European RoHS regulations. It is an emerald green battery. However, lead-acid batteries contain a lot of lead. If the waste is not properly resolved, it will still cause secondary pollution to the natural environment. 8. No memory: When the rechargeable lithium battery is often working under the condition of battery charging, the battery charging capacity will quickly drop below the short-circuit capacity. This type of condition is called memory. For example, nickel-hydrogen rechargeable batteries, nickel-cadmium batteries, lead-acid batteries, etc. have memory capacity, while lithium iron phosphate batteries have no condition. Regardless of the situation, the rechargeable battery can be used at any time without putting it out first. Backlash. For air iron, the lithium battery pack can store electromagnetic energy during the low tide of electricity consumption at night, which is low-carbon and environmentally friendly. In fact, the advantages of lithium battery packs go far beyond empty iron. Lithium battery packs are also commonly used in many other industries. Scope of application: small and medium mainframe rooms, weak current installation rooms, outdoor new energy technology stations, communication base stations, no central air-conditioning stations outside the room, no one station for TV broadcasting, military, crude oil, climate, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
