Modification of the car battery Lithium iron phosphate batteryIt cannot be said that it is absolutely stable. The following is for reference only:
This car has. a big problem, that is, it is a ternary battery. Technically speaking, the current lifespan of ternary batteries is only 500 to 800 weeks, which is half of the lifespan of lithium iron phosphate which is 1000 to 1500 weeks. Therefore, the battery life of this car is about 100,000 kilometers, and the 120,000-kilometer car warranty confirms this. If it is replaced with a lithium iron phosphate battery, judging from the current battery performance, there will be no big change in the car data, and the battery life will reach 200,000 kilometers .
The current energy density of lithium-based passenger car systemsium iron phosphate is 140 wh/kg, which is not wrong compared to the common energy density of ternary battery system passenger cars of 140 wh/kg.
It can also achieve 40.5 kW/h storage capacity, but it increases the quality of the car and doubles the life of the car battery.
For extended range electric vehicles, a range of more than 150 km is sufficient, and the vehicle battery life is very important at this time.
The lifespan of most family cars exceeds 100,000 kilometers but rarely exceeds 200,000 kilometers.
