Daily use habits and maintenance precautions for pure electric vehicles

The biggest difference between pure electric vehicles and traditional fuel vehicles is the drive system. If you want to maintain a pure electric vehicle and keep it in peak condition, you must maintain its three-electric system, especially the power battery. Next, we will focus on the daily maintenance of the power battery.

Slow charging as the main function, fast charging as the auxiliary function

Fast charging can cause great damage to power batteries, after all, it is a high-current charging method. Therefore, the charging strategy for pure electric vehicles should be based on slow charging and supplemented by fast charging. In other words, if there are conditions for installing charging piles at home, it is better to charge as needed.

Maintain good driving habits

Reducing the frequency of fast charging is to reduce the occurrence of power battery overcharging, and maintaining good driving habits is to avoid the problem of power battery over-discharge as much as possible. For example, in normal driving, try not to accelerate or decelerate suddenly, and don't drive on the highway, that is, to minimize the problem of power battery over-discharge. Try to avoid driving on potholes, which may cause the power battery to be hit.

Avoid deep feeding

If the car is parked for a long time, it is necessary to recharge the power battery regularly. In normal use, before going out, you should also plan your driving route and try not to allow the car to be in a deep charging state. If the power battery is often in a deep charging state, it will have a great impact on its service life.

Try to avoid charging in extremely cold environments.

The working principle of the power battery is as follows: when charging, the Li+ in the positive electrode and the Li+ in the electrolyte gather toward the negative electrode, gain electrons, and are reduced to Li embedded in the carbon material of the negative electrode. When discharging, the Li embedded in the carbon material of the negative electrode loses electrons and enters the electrolyte, and the Li+ in the electrolyte moves toward the positive electrode. Under extremely cold conditions, the activity of the power battery will be greatly reduced. Simply put, it affects the activity and movement speed of lithium ions, thereby affecting the charging efficiency and causing greater damage to the battery. This is similar to the fact that the battery of mobile phones is not durable in winter.

summary

The maintenance of power batteries is crucial for pure electric vehicles. During normal use, you need to maintain good driving habits, try to avoid charging in extremely cold environments, and use slow charging as the main method and fast charging as the auxiliary method. When parking for a long time, you should also regularly recharge the electric vehicle to avoid deep feeding.
