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 needs more than 39,000 yuan, and the cost of the lithium iron phosphate battery is lower than that of the ternary lithium, which is about five to six hundred yuan.
2. Battery capacity: It takes about 24,000 yuan, which is 10,000 to 20,000 yuan different from the cost point of view. For the highly competitive electric vehicle market, the saved cost can be used for vehicles in the market. More improvements, and secondly, because the mini scooter does not need to be too high in the vehicle's capacity density, it can meet the daily mobility.
3. Battery safety and stability: Lithium iron phosphate batteries have an advantage. Regardless of the cost of the vehicle or the safety performance, for small cars, the use of lithium iron phosphate batteries will be more suitable.
Lithium iron phosphate batteries are used in miniature electric vehicles to meet the vehicle's driving mileage requirements, reduce vehicle manufacturing costs, extend vehicle life, and increase vehicle cost performance. In addition, the lithium iron phosphate battery has higher safety performance and supports large rate charge and discharge, so it is more suitable for equipping miniature electric vehicles than ternary lithium batteries.
