Now, with the continuous support of the state for new energy electric vehicles, and the news report that some European countries announced that they would stop selling fuel vehicles around 2035, more and more car owners began to choose new energy electric vehicles as the second car in their families. But as a new thing, many people do not know how to maintain new energy electric vehicles. In fact, when it comes to maintenance, new energy electric vehicles mainly focus on battery maintenance.
1: How to charge
During normal driving, if the red light and yellow light of the electricity meter are on, it should be charged; If only the red light is left on, stop the operation and charge as soon as possible, otherwise excessive discharge of the battery will seriously shorten its life. The charging time should not be too long, otherwise it will cause excessive charging and the battery will heat up. Overcharging, overdischarging and undercharging will shorten the battery life. Generally, the average charging time of the battery is about 8-10 hours. The ambient temperature range for vehicle charging is 0C-45C. When the ambient temperature is lower than 0C or higher than 45, please try not to charge the vehicle.
2: How to maintain the battery
One is the need for regular deep discharge, which is conducted once every 2 months, which is conducive to activating the battery properties and slightly improving the battery capacity, which is very beneficial to the battery. The second is that it is better to charge every day. After the indicator shows that most chargers are fully charged, the actual charge is about 97%~99%. Although the difference of 1%~3% of the charge has little effect on the continuous ability, it will form under charge accumulation. So when the battery indicator shows that the battery is fully charged, try to charge it as much as possible. And charging every day can make the battery in a shallow cycle state, which is conducive to extending the battery life.
In addition, when charging or maintaining, we should strictly refer to the battery operation manual. We should not charge the battery with mismatched charging lines, nor modify charging equipment without permission. After 2-3 months of normal use, you should perform a regular maintenance on the battery and check the performance of the battery pack.
3: What should I do if the car is not used for a long time
The battery will discharge itself slowly when it is not used for a long time, until it is scrapped. Therefore, the vehicle should be started every once in a while to charge the battery. If you find this troublesome, remove the two electrode wires on the battery. At this time, you should pay attention to removing the positive and negative electrode wires from the electrode posts. Remove the negative wire or the connection between the negative wire and the chassis, and then pull out the other end with the positive sign.
The battery has a certain service life, and should be replaced after a certain period of time. The above sequence shall also be followed during replacement, while the reverse sequence shall be followed when connecting the electrode wires. Connect the positive electrode first, and then the negative electrode.
4: Avoid high current discharge
When starting, carrying people and going uphill, electric vehicles should not step on the accelerator as hard as possible. Instantaneous high current discharge will produce lead sulfate crystals, which will damage the physical performance of the battery plates.
5: What are the symptoms of battery problems
If the running range of the electric vehicle suddenly drops by a large margin of more than ten kilometers in a short time, it is likely that at least one battery in the battery pack has a problem. At this time, you should go to the 4S store for inspection, repair or assembly in time. This can relatively extend the life of the battery pack and save your expenses to the greatest extent.
Summary:
Of course, we should also pay attention to develop a good habit of using cars to prevent problems before they occur. Good driving habits are also a way to maintain and prolong the life of batteries. In addition, we should pay attention to the dryness and ventilation of the charging environment, avoid the rain and sun, let the batteries run or charge in a good environment, and reasonably control the charging time.
In general, we should carefully understand the performance of new energy electric vehicles, especially the battery performance, clearly grasp the charging time, maintenance date, and take measures to extend the battery life and achieve real green travel!
