Background
The battery is a main driving motor of the new energy automobile, the ternary lithium battery is one of the main batteries of the new energy automobile, and the service life and the replacement time of the ternary lithium battery are determined by the following elements.
Firstly, the starting habit of a driver of the new energy automobile is that the new energy automobile is fast to accelerate, the discharge multiplying power is high due to the fact that the driver steps on the new energy automobile too fast, the service life of the battery is shortened, and if the driver slowly accelerates, the method is helpful for prolonging the service life of the battery of the new energy automobile.
Secondly, in order to prolong the service life of the battery, the battery is not charged until the electric quantity is less than 20%, the electric quantity is controlled between 25% and 75% as much as possible, the battery attenuation can be reduced, the service life of the battery is related to the cycle number, the cycle number is calculated from 0 electricity to full electricity once, and if the battery is full from 50%, the cycle number is calculated once after charging twice.
Again, if the vehicle is parked for a long time and not charged, the service life of the new energy battery is adversely affected, many new energy automobile users may use the vehicle frequently not very much, the vehicle is put for a few months or the battery is not charged at regular intervals, and of course, the situation that the electric load is overlarge is caused when the charging is not carried out for a long time, and the service life of the battery is reduced when the charging is carried out for a long time.
Finally, the temperature of the working environment of the new energy battery has great influence on the battery, the battery is not required to be driven or charged in the environment higher than 60 ℃, the heat dissipation of the battery is influenced by the excessively high temperature, the fire disaster is caused by more serious explosion, the new energy vehicle is not required to be charged when the temperature is lower than-5 ℃, and the battery can be self-protected when the temperature is too low.
Generally, when the maximum capacity of a ternary lithium battery is reduced to eighty percent of the maximum capacity in a factory state, the battery should be replaced. However, in actual use, people do not determine the number of remaining charge cycles between the current time and the time when the maximum capacity of the ternary lithium battery is reduced to eighty percent of the maximum capacity of the factory state, so that the battery replacement time cannot be effectively grasped.
