The light-duty vehicle has the characteristics of small body, affordable price, economy and practicality, and does not have high requirements for speed and driving range.
At present, the single energy density of LiFePO4 can reach about 180-200Wh/kg, although it can not be compared with the 260-300Wh/kg of NCM batteries, but the mini-electric vehicles equipped with LiFePO4 could reduce motor power to realize continuous driving distance 300 kilometers. In other words, the use of LiFePO4 for light-duty vehicles can satisfy market demand in terms of driving range.
As the battery capacity of the light-duty vehicle is relatively small, the time required to complete a charging cycle is also much shorter. At present, LiFePO4 battery’s cycle life could reach more than 2000 times, while that of NCM battery could only do about 800-1000 times. Since the service life of the power battery basically determines the service life of the electric vehicle, the use of LiFePO4 in the light-duty vehicle can greatly extend the service life of the vehicle and effectively improve the cost performance. Therefore, for a light-duty vehicle with a short cruising range, LiFePO4 battery is advantageous.
Why is the light-duty vehicle more suitable for LiFePO4?
1. Price: For the power battery, the cost of the power battery occupies about half of the price of the whole car. Taking the Chery eQ1 mini car of about 60,000 yuan as an example, the battery capacity is 30.6kWh. Judging from the price of the existing ternary lithium battery, the battery costs more than 39,000 yuan, and the cost of the LiFePO4 battery is lower than that of the ternary lithium, which is about five to six hundred yuan.
2. Battery capacity: a cost of about 24,000 yuan is required. From the cost point of view, there is a difference of 10,000 to 20,000 yuan. For the highly competitive electric vehicle market, the saved cost can be used in the market for More improvements are made to the vehicle. Secondly, because the light-duty vehicle does not need to be too high in the vehicle's capacity density, it can meet the daily mobility.
3. The safety and stability of the battery: the structure of LiFePO4 is more stable than that of NCM.
In summary, LiFePO4 is more suitable for light-duty vehicles with shorter driving mileage requirements, no matter from cost, service life or safety.
