Precautions for using the power battery of new energy electric vehicles: 1. Remember to avoid collision with the battery pack. The power battery pack of electric vehicles is generally arranged at the bottom of the load-bearing body. When the vehicle passes through some bumpy roads, remember to pay attention to the collision of the chassis, as the collision of the chassis may damage the power battery pack.
In addition, after a vehicle collision accident, it is necessary to check the degree of damage to the power battery pack in a timely manner. Otherwise, the power battery pack is likely to deform due to the collision, causing internal short circuits in the power battery pack, ultimately leading to local overheating and causing the vehicle to self ignite.
2、 Remember that when cleaning electric vehicles, the power battery pack should not be exposed to water. Although the waterproof and sealing properties of the car are very good, it is best not to directly clean the power battery with a high-pressure water gun when cleaning electric vehicles. Otherwise, it is likely that water and short circuits may occur due to poor sealing of individual components, which can lead to serious consequences. Therefore, during the cleaning process of electric vehicles, pay attention to the pressure of the cleaning area and the high-pressure water gun.
3、 Pay attention to the operating temperature of electric vehicles. The optimal operating temperature for electric vehicles is between 10-30 ℃, and ensure good ventilation and heat dissipation.
If the ambient temperature is too low, it can lead to insufficient charging of the power battery, a decrease in capacity, and a decrease in battery life during discharge.
At the same time, if the ambient temperature is too high, it is easy to cause the power battery to overheat and lose control. During the charging process, the battery will overheat and expand, damaging the power battery.
4、 Avoid excessive discharge and pay attention to the battery level display on the instrument panel. Electric vehicles should pay more attention to the battery level display on the instrument panel during daily use.
It is best not to wait for the power battery to run out of battery before charging, as excessive discharge of the power battery can greatly affect its service life.
At the same time, attention should also be paid to the remaining driving distance of the power battery on the instrument panel. It is best not to exceed 2/3 of the longest driving distance in a fully charged state (for example, the best driving distance for a vehicle in a fully charged state of the power battery is 150 kilometers, and it is best not to let the vehicle travel more than 100 kilometers) before charging.
5、 Avoid long-term storage of electric vehicles. Try to avoid storing electric vehicles for a long time, as long-term storage can reduce the service life of the power battery due to insufficient charging.
So when storing electric vehicles, it is necessary to ensure that the power battery is in a fully charged state, and to ensure that the power battery is recharged every month.
6、 When there is an overheating alarm for the power battery, it is important to remember to park the car for cooling. The driving computer of the electric vehicle has done a very good job in protecting the power battery from overheating.
Therefore, when the vehicle experiences an overheating alarm for the power battery, it is important to stop the vehicle and provide sufficient heat dissipation for the power battery.
Don’t act recklessly. If the power battery overheats and the alarm still goes off, it is likely to cause the power battery to overheat or even the vehicle to self ignite.
7、 Firefighting equipment is indispensable, and the accuracy of charging equipment is high. Both gasoline powered and electric vehicles have a certain risk of spontaneous combustion, especially in the hot summer. Therefore, vehicles should be equipped with fire-fighting equipment, fire extinguishers, escape hammers and other fire-fighting equipment, which should be kept in the vehicle regularly to prevent accidents.
In addition, the charging accuracy of electric vehicle charging devices must be high, and it is best to use original charging equipment for charging. High charging accuracy has great benefits for power batteries.
