Technical advantage


1. High monomer capacity

The power battery must have enough capacity and voltage to ensure the mileage of the electric vehicle at one time, and the key factor is the specific energy of the battery. At present, the mass ratio of power battery for electric vehicles used in the domestic and foreign markets is about 130Wh/kg. However, the mass specific energy of the high energy battery is more than 220Wh/kg, which is 1.7 times that of the LiFePO4 battery, 3-4 times of the Ni MH battery and 8-10 times of the lead-acid battery.

2. Long cycle life

The cycle life of long-life lead-acid battery is about 300 times, the highest is 500 times. The loop life of the battery is 2000 times, and the standard charge (5 hours rate) can reach 2000 times. The same quality lead-acid battery is "new half year, half a year, maintenance and maintenance for half a year", most of which will be 1~1.5 years. The life of the ring high-tech battery will be 7~8 years under the same conditions. In comprehensive consideration, the performance price is more than 4 times that of the lead-acid battery in theory. High current discharge can be used for fast charging and discharging of 2C at large current. Under the special charger, 1.5C can charge 40 minutes to make the battery full, and the starting current can reach 2C, but lead-acid battery has no such performance.

3. Large capacity

A charge is often not in the pool full of out of work under capacity will rapidly below the rated capacity value, this phenomenon is called memory effect. Like Ni MH and Ni Cd batteries, there is memory in the battery. However, the battery doesn't have this phenomenon. No matter what the battery is in, it can be used with charge, and it doesn't need to be discharged before it is recharged.

4. Light weight

The volume of the battery with the same size is 1/3 of the size of the lead-acid battery, and the weight is the 1/3 of the lead-acid battery.

5, environmental protection

The loop battery is generally considered to be free from any heavy metals and rare metals (nickel hydrogen batteries need rare metals), non-toxic (SGS certification), no pollution. It is in line with the European RoHS regulations, and is the absolute green battery certificate. So the reason why lithium battery is favored by the industry is mainly environmental considerations. Therefore, the battery has been included in the "863" national hi tech development plan during the "fifteen" period, and has become a national priority support and encouragement development project. With China's entry into the WTO, the export volume of electric bicycles in China will increase rapidly, and the electric bicycles in Europe and America have been required to be equipped with non polluting batteries.

6. High mass is higher than energy

The power battery must have enough capacity and voltage to ensure the mileage of the electric vehicle at one time, and the key factor is the specific energy of the battery. At present, the mass ratio of power battery for electric vehicles used in the domestic and foreign markets is about 130Wh/kg. However, the mass specific energy of the high energy battery is more than 220Wh/kg, which is 1.7 times that of the LiFePO4 battery, 3-4 times of the Ni MH battery and 5-8 times of the lead-acid battery.
