What are the factors that affect the service life of electric vehicle batteries?

In general, the factors affecting the service life of electric vehicle batteries can be divided into the following four aspects: First, the performance and quality of the battery itself, that is, the brand and quality of the battery purchased by the user, and the battery life of some brands can be guaranteed. Second, the user’s riding habits are also a major factor affecting the battery life. For example, users know how to cherish the battery, if they know how to drive uphill, do not discharge to the end frequently, start slowly, do not slam the switch, etc. Effectively extend battery life. Third, the matching of the battery and the electric vehicle motor and controller has two most important factors affecting the service life of the battery in the electric vehicle system: one is the efficiency state of the motor; the second is the design of the charger. If the motor efficiency range is narrow, on the one hand, the power consumption level will increase, and on the other hand, it will often work in the low-efficiency area. The inside of the motor is prone to heat. When the temperature is too high, the magnetic material will be irreversibly demagnetized. Over time, the efficiency will be further improved. This electric car will become an electric tiger in a sense, even if the battery is replaced, it will not help. In addition, the factors that cause the motor to reduce the efficiency are: excessive wear of the brushes and plane commutation. The wear of the motor, the wear of the deceleration system, etc. Therefore, customers should choose a motor with better performance and pay attention to maintaining contact with maintenance services and replacing worn parts when they are due to help make good use of the electric vehicle. Fourth, more important than the above 3 points is the statement on the performance of the on-board charger: Some pictures and content of the articles published on this site are from the Internet.
