Car Battery With High Quality Maintenance Free Car Starting Batteries
Product feature
1. Ultra long service life, the best battery cycle life of lithium iron phosphate power battery can reach more than 2000 times, and the standard charging (5-hour rate) can reach 2000 times. Lithium iron phosphate batteries have undergone strict safety tests and will not explode even in the worst traffic accidents.
2. High temperature resistance, lithium iron phosphate electric heating peak can reach 350 ℃ ~ 500 ℃
high-capacity.
3. No memory effect.
4. Small size and light weight.
Power battery group technology
1. High energy density
Deepen the systematic and integrated design of power battery modules, improve the existing group production process, and then improve the safety and reliability of group power batteries. The technical requirements of group power batteries are as follows.
2. Lightweight design
Improve the energy density of the power battery pack to meet the driving mileage of electric vehicles. There are two ways to improve the energy density of power battery pack: one is to improve the group efficiency, and the other is to use cells with higher energy density. At present, the square cell will mainly promote products with energy density of 230 ~ 240wh / kg, the soft package will mainly promote products with energy density of 240 ~ 260wh / kg, 18650 cell will launch products with energy density of 3.2 ~ 3.4ah, and 21700 cell will launch products with energy density of 4.8 ~ 5.0ah.
