With the popularity of new energy vehicles, more and more car owners are beginning to enjoy the convenience of green travel. But in summer, extreme weather such as high temperature, heavy rain, and exposure to the sun frequently occurs, and the charging safety and battery life of new energy vehicles face multiple tests. If you are not careful, the battery may be damaged, and even cause safety hazards. The following summer charging precautions must be remembered by new energy vehicle owners!
1. Avoid charging immediately after high temperature exposure
Avoid charging immediately after high temperature exposure. The outdoor temperature in summer often exceeds 35C. After the vehicle is exposed to the sun for a long time, the battery temperature may soar to more than 50C. If you charge immediately at this time, the chemical reaction inside the battery will be more intense, which will not only accelerate the aging of the battery, but also trigger the vehicle’s overheating protection mechanism due to excessive temperature, resulting in a significant decrease in charging speed and even safety risks.
It is recommended to let the vehicle cool naturally for 30 minutes to 1 hour after parking, and then charge after the battery temperature drops. If conditions permit, try to park the vehicle in a cool place such as an underground parking lot or under the shade of a tree to reduce the exposure time. This can protect the battery and improve charging efficiency.
2. The charging environment should be ventilated and away from flammable materials
Whether it is a home charging pile or a public charging station, ensure that the environment is well ventilated when charging. In hot weather, the battery will generate heat during the charging process. If the charging environment is closed, the heat cannot be dissipated in time, which can easily cause local overtemperature and affect battery performance and safety.
At the same time, the charging area should be away from flammable and explosive items, such as cartons, plastics, etc. Some car owners have a lot of debris at their charging locations, which is very dangerous. Once a short circuit or other faults occur during the charging process, sparks can easily cause a fire. Therefore, when choosing a charging location, be sure to keep the surrounding environment clean and safe.
3. Be cautious about outdoor charging in rainy weather
There are frequent rainstorms in summer. If the outdoor charging piles and charging interfaces are not properly protected, water can easily enter and cause short circuits. Before charging, carefully check whether the surface of the charging pile is damaged or water ingress is present, and whether the charging interface is dry and clean. If the outer shell of the charging pile is found to be damaged or there are water stains inside, do not use it, and contact the relevant department for repair in time.
For the charging interface of the vehicle, although some models have a certain waterproof level, they should not be taken lightly. When plugging and unplugging the charging gun, try to shield it with your body or other objects to avoid splashing rain. If you encounter heavy rain during charging, stop charging immediately to ensure safety.
4. Reasonably control the charging time and avoid overcharging
The batteries of new energy vehicles have a certain charge and discharge cycle life, and overcharging will accelerate battery aging. When charging in summer, do not keep the vehicle in a fully charged state for a long time in pursuit of higher power. Generally speaking, when the power is charged to 80%-90%, the charging efficiency is the highest and the loss to the battery is the smallest.
Now many new energy vehicles support the charging setting function, and the charging upper limit can be set through the vehicle’s central control screen or mobile phone APP. It is recommended to set the charging upper limit to about 90%, which can not only meet daily travel needs, but also effectively protect the battery. If you are using fast charging, you should pay more attention to controlling the charging time. Although fast charging is fast, frequent excessive fast charging will cause certain damage to the battery.
5. Check charging equipment and lines regularly
In summer, it is hot and rainy, and charging equipment and lines are prone to aging, breakage and other problems. Car owners should regularly check whether the lines of home charging piles are exposed or broken, and whether the interface of the charging gun is loose or deformed. If the line is found to be aging or the charging gun is damaged, it should be replaced in time to avoid dangers such as leakage and short circuit caused by line failure.
For public charging piles, a simple inspection should also be carried out before use to check whether the indicator light of the charging pile is normal and whether the charging cable is worn. If during the charging process, the charging pile is found to have abnormal conditions such as abnormal noise, smoke, and heat, immediately press the emergency stop button on the charging pile, cut off the power supply, and stay away from the scene, and contact the staff in time for processing.
6. Avoid using high-power vehicle-mounted equipment during charging
During the charging process of the vehicle, try not to use high-power equipment such as vehicle air conditioning and heated seats. Because the operation of these devices will increase the load on the battery, it will not only prolong the charging time, but also may cause the battery to overheat, affecting charging safety and battery life.
If you really need to wait for charging in the car, you can turn off unnecessary equipment, choose natural ventilation or use a low-power vehicle-mounted fan to cool down. At the same time, avoid using the vehicle’s entertainment system for a long time while charging to reduce additional battery consumption.
The battery of a new energy vehicle is like its “heart”. Only by doing a good job of charging protection in summer can this “heart” beat more healthily and last longer.
