What are the influencing factors of electric vehicle batteries?

Electric vehicles are popular among consumers because of their convenience and environmental protection. Electric vehicle batteries are the power source of electric vehicles. So, what are the factors that affect electric vehicle batteries? 　　1. Reasons for lower temperature 　　 (1) Battery temperature effect-the colder the weather, the lower the battery capacity. Example: The capacity is only 85% at zero degrees. Chemical reactions occur during battery charging and discharging. The lower the temperature, the lower the activity of the active material, the higher the internal resistance and viscosity of the electrolyte, the more difficult it is for ion diffusion, and the difficulty of battery charging and discharging, which affects the mileage. After the winter, the climate will pick up and the battery mileage will rise. this is normal phenomenon.　　 (2) The effect of vehicle efficiency-the colder the weather, the lower the vehicle efficiency. Example: The efficiency of the vehicle drops by 5% at zero degrees. In the process of riding the whole vehicle, the battery converts chemical energy into electrical energy, the electrical energy is converted into mechanical energy through the motor, and the mechanical energy is converted into kinetic energy through the transmission mechanism, and the vehicle starts to run. The conversion efficiency of the motor and the transmission mechanism will be affected by the ambient temperature. this is normal phenomenon.　　 (3) Vehicle load impact-the colder the weather, the more clothes consumers wear, the heavier the vehicle load is, and the more power it consumes. This is an inevitable phenomenon.　　　　 2. Reasons for battery aging. 3. Reasons for improper charging and discharging: improper charging and discharging will make the battery age faster.　　Four. Reasons for excessive load: Excessive load will speed up the power consumption and reduce the cruising range.　　 5. Reasons for insufficient tire pressure: If the tire pressure is insufficient, it will increase the resistance of the electric vehicle to move forward, consume limited electric energy in vain, and reduce the cruising range.　　 There are many influencing factors of electric vehicle batteries. Here are just a few common problems, I hope it will be helpful to everyone. Previous: How to change the battery of an electric car?
