The biggest difference between pure electric vehicles and traditional fuel vehicles is the driving system. In order to maintain the pure electric vehicle and keep the pure electric vehicle in a peak state, the three electric systems, especially the power battery part, are required to be maintained. In the following, we make an important introduction for the daily maintenance of the power battery.
Slow charge is mainly and fast charge is auxiliary
The damage to the power battery caused by the quick charge is still very large, and after all, the battery is charged with large current, so that the battery supplementing strategy for the pure electric vehicle is mainly and quickly charged. That is, if the charging pile is installed in the home, the charging pile is better when the charging pile is used.
Keep good driving habit
The frequency of quick charge is reduced in order to reduce the occurrence of overcharge of the power battery, and the problem of overdischarge of the power battery is avoided as much as possible while maintaining good driving habits. If the driver does not need to accelerate and decelerate rapidly as much as possible in the usual driving process, and does not need to run up at a high speed, namely the problem of overdischarge of the power battery is reduced as much as possible. Avoiding the possibility of the power battery being impacted when the vehicle runs on the hollow road surface as much as possible.
Avoiding the occurrence of deep feed conditions
If the vehicle is parked for a long time, the power battery needs to be charged regularly, and in the normal use process, a driving path is planned before going out, so that the deep feeding state is avoided as much as possible. The power cells are often in a deep feed state and the effect on their useful life is still significant.
Avoiding charging in extremely cold environment as much as possible
The working principle of the power battery is as follows: during charging, li+ in the positive electrode and Li+ in the electrolyte are gathered to the negative electrode, electrons are obtained, and Li is reduced to be embedded in a carbon material of the negative electrode. During discharge, li embedded in the cathode carbon material loses electrons, enters electrolyte, and Li+ in the electrolyte moves to the anode. Under extremely cold conditions, the activity of the power battery can be greatly reduced, and the activity and the moving speed of lithium ions are influenced simply, so that the charging efficiency is influenced, and the battery is greatly damaged. The electric quantity of the mobile phone is not durable in winter, and the principle is different in size.
Those matters to be noted when the new energy electric automobile is used:
first: the charging mode is to pay attention to that the new energy electric automobile is charged without being used normally. During charging, two modes of fast charging and slow charging are selected. Many owners use quick charge regardless of time. This is not true. Charging is the infusion of energy into a power battery. In the fast charge mode, the flow rate of electrons is increased, which may cause the temperature of the battery to rise too fast, thus causing some unfavorable situations. For example, the charge cannot be balanced, and a common 'virtual electricity' condition can occur. The long-term use also has an influence on the service life of the battery. The slow charging voltage is small, and the charging time can be long, but the power battery cannot be damaged. The correct charging method should be: when the driver does not drive the time, the electric quantity is supplemented in a slow charging mode as much as possible. The quick-charging is only used for emergency. This reduces the extra loss to the power cell.
New energy automobiles are contraindicated for overcharge, overdischarge and undercharge, which all shorten the service life of the battery. In the use process, the charging time and the charging frequency are determined according to the actual vehicle condition, if the indicator lamp of the electricity meter is lighted, the electricity meter is charged as soon as possible, otherwise, the service life is influenced by the overdischarge of the storage battery.
And the charging time is not too long, otherwise, overcharge is formed, so that the storage battery heats. If the temperature of the storage battery exceeds 65 ℃ in the charging process, the charging should be stopped immediately so as not to be dangerous.
Second,: the maintenance of vehicles is important to the construction of new energy automobiles and is different from that of fuel automobiles, and there are many differences in maintenance projects. Like our familiar oil change. The electric automobile is not needed at all. Many conventional maintenance projects for electric vehicles are based on inspection and detection. Some car owners feel that the maintenance material is not replaced, and the inspection is not important. Such an idea is wrong and dangerous. The new energy electric automobile mainly works in a linked manner by a circuit, so that the circuit is complex, and the automobile is used for a period of time. Some safety hazards may also occur. Each maintenance inspection is to eliminate the potential safety hazards, so that maintenance is important.
Third,: it is clear that the environment influences the new energy electric automobile to use is mostly a ternary lithium battery. In a low temperature environment, it can go out of the attenuation phenomenon. The external environment temperature is low in winter, and the chemical reaction of the power battery of the electric automobile can be slowed down. The charging speed of the electric automobile is reduced, the endurance mileage is shortened, the external temperature is about 10 ℃ below zero, and the power battery can attenuate 30% of the endurance mileage. And the lower the temperature, the more attenuated. Therefore, when the electric automobile is used in winter, the automobile strength is reasonably arranged in consideration of the attenuation condition of the power battery. When long distance bus is needed, the pure electric vehicle is preferably not used.
The application realizes the comprehensive health management of the batteries of the electric vehicles through the comprehensive management system, provides powerful technical support for the development of the electric vehicle industry, and also provides technical reference for the automation of future unmanned vehicles.
