The battery of new energy vehicles needs to be stored after sufficient power and replenished once a month to maintain the healthy state of the battery and avoid long-term power loss resulting in sulfation of the battery plates. The longer the vehicle is idle, the more damaged the battery will be.
1. Remember to avoid battery pack collisions.
The power battery pack of electric vehicles is generally arranged at the bottom of the load-bearing body, and when the vehicle passes through some potholes, remember to pay attention to the scratches of the chassis, because the scratches of the chassis are likely to hurt the power battery pack. In addition, after the vehicle crashes, it is necessary to check the damage degree of the power battery pack in time, otherwise the power battery pack is likely to be deformed due to the collision, resulting in a short circuit inside the power battery pack, and eventually causing local overheating and causing spontaneous combustion of the vehicle. Do not charge during thunderstormsRain is often accompanied by thunder, do not charge at this time, so as not to be struck by lightning, causing combustion accidents, resulting in certain property losses.
2. Remember that when the electric vehicle is cleaned, the power battery pack cannot enter the water.
Although the waterproofness and sealing of the car are very good, when cleaning the electric vehicle, it is best not to clean the high-pressure water gun directly against the power battery, otherwise it is likely to be short-circuited due to the poor sealing of individual components, and the consequences may be very serious, so in the process of cleaning the electric vehicle, pay attention to the pressure of the cleaning part and the high-pressure water gun.
3. Pay attention to the use temperature of electric vehiclesThe best use temperature of electric vehicles is 10-30, and ensure good ventilation and heat dissipation. If the ambient temperature is too low, it will lead to insufficient charging of the power battery, the capacity will decrease, and the life of the battery will be reduced during the discharge process. At the same time, the ambient temperature is too high, which is easy to cause the power battery to overheat and runaway, and the battery will overheat and expand during the charging process, damaging the power battery.
Do not charge immediately after high temperature exposure After long exposure, the temperature of the power box of new energy electric vehicles climbs, causing the temperature of the battery in the car to rise. If you charge it immediately at this time, it will accelerate the aging and damage of the wiring in the car. (The maximum charging temperature of the battery pack should be less than 55°C).
4. Avoid over-discharge and pay attention to the battery level display of the instrument.
When electric vehicles are used in daily use, they should pay more attention to the battery level display of the meter. It is best not to wait for the power battery to lose power before charging, because the over-discharge of the power battery will greatly affect the service life of the power battery. At the same time, it should also be noted that the remaining mileage of the power battery on the instrument, the mileage should not exceed 2 3 of the longest mileage in the fully charged state (for example, the best mileage of the vehicle in the full state of the power battery is 150 kilometers, it is best not to let the vehicle travel more than 100 kilometers) and then charge.
5. Do not drive the air conditioner and other in-car equipment when charging.
Turning on air conditioning and other equipment when charging new energy vehicles will increase the sound charge load in the on-board battery, accelerate the battery attenuation of the power battery pack, and reduce the service life of the battery.
6. Avoid long-term storage of electric vehicles.
Try to avoid storing the electric vehicle for a long time, because long-term storage will reduce the service life of the power battery due to long-term insufficient charging. Therefore, when storing electric vehicles, it is necessary to ensure that the power battery is in a fully charged state, and ensure that the power battery is replenished and charged every month. It is best to arrange charging every day for normal use, and when the fuel gauge shows low power, it should be charged as soon as possible to avoid over-discharging the battery; The fuel gauge shows that it is fully charged, and charging should be stopped to avoid overcharging. Over-discharge, over-charge, and under-charging will affect battery performance, shorten battery life, and cause safety risks in serious cases.
7. When the power battery overheating alarm, remember to stop the car to dissipate heat.
The overheating protection of the power battery of the electric vehicle trip computer is very well done. Therefore, when the vehicle has an overheating alarm for the power battery, remember to stop and fully dissipate the heat from the power battery. Don't insist on going your own way, the power battery overheating alarm is still driving, in that case, it is likely to cause the power battery to overheat and even the vehicle to spontaneously combust.
8. Fire-fighting equipment is indispensable, and the charging equipment has high precision.
Both fuel vehicles and electric vehicles have a certain risk of spontaneous combustion, especially in the hot summer, so the car should be equipped with fire-fighting equipment, fire extinguishers, escape hammers and other fire-fighting equipment should always be in the car in case of accidents. In addition, the charging accuracy of the charging device of the electric vehicle must be high, and it is best to use the original charging equipment for charging, and the high charging accuracy is of great benefit to the power battery.
9. Choose a charging pile that meets national standards.
Develop a good habit of checking the appearance of the vehicle and the charging equipment such as the charging port before charging, and ensure that the charging environment is ventilated and dry when charging in winter. This not only protects the car's battery, but also protects its own safety.
New energy vehicles are the development trend of the future automotive industry, and the biggest advantage of electric vehicles lies in its environmental protection and economy. In the process of using electric vehicles, you should pay attention to the above seven aspects of precautions, in order to better drive the vehicle, extend the service life of the power battery, and protect the safety of your family and yourself, I hope today's content can help you.
