1、 Charge in time
For pure electric vehicles, the biggest impact of using vehicles in winter is the battery life. Presumably, you have also experienced this experience. Every winter, especially outdoors, the cell phone battery will power down very quickly, and the power will rise again after returning to the house for a while. Similar problems will occur in pure electric vehicles after entering winter. In fact, the key reason for such problems is related to the reduction of battery activity. When the external temperature is getting lower, the activity of particles in the battery will be reduced, and finally the problem of halving the endurance will occur. In addition, the reduction of battery activity will also lead to problems such as slow charging and insufficient charging, so in order to ensure battery overflow, it is necessary to appropriately delay the charging time or preferably choose to charge in the indoor parking lot.
2、 Pay attention to the charging time
We all know that correct use and maintenance of batteries can effectively prolong the service life of batteries. The characteristic is that in winter, due to the influence of temperature, the battery life is short, and the charging cycle and times will become more frequent. According to the household 220V voltage, charging in low battery mode should be controlled at 6-10 hours. If the charging time is too long, the battery performance will be reduced. At present, most pure electric vehicles can use mobile phone APP to view the current charging progress and other information. At this time, pay attention to the battery temperature during charging. If the charging temperature is too high, power off immediately to avoid damage to the battery.
3、 Check battery and charging port
At present, most of the batteries carried by the common new energy vehicles on the market are ternary lithium-ion batteries. Although this lithium-ion battery has the advantages of light weight and large capacity, it also has a fatal defect, that is, it is very easy to ignite and burn. Once the outer package of the battery is damaged or deformed, the internal lithium-ion battery will easily ignite. Therefore, after entering the winter, it is also very important to check whether the battery is deformed or leaking. Once a problem is found, it should be repaired at the 4S store in time. In addition, there is a lot of snow in the north in winter, and the water from melting snow is likely to flow into the charging port. It is suggested to do a good job of cleaning before each charging to avoid unnecessary trouble after melting snow.
4、 Idle vehicles should be properly stored
Nowadays, many families who buy new energy vehicles are already the second car. Generally, considering the winter endurance of pure electric vehicles, they simply choose not to drive and use another fuel version. While storing pure electric vehicles in winter, we should also find a good place for them. It is better to park them in the underground garage, so that the temperature will not be too low to affect the battery. In addition, the vehicles parked for a long time should be charged regularly to keep the battery capacity above 30%, otherwise the battery life will be affected if the battery loses power.
Although the battery of pure electric vehicles has its own thermostatic system, the battery can not reach the best working temperature quickly when it is used in winter, so the pure electric vehicles also need to be hot. Moreover, the power system, circuit and motor in the pure electric vehicle must reach a certain temperature to enter the most ideal working environment. Therefore, you can start the vehicle remotely and turn on the air conditioner at the same time to warm the vehicle first, so that you will have a comfortable environment after getting on the vehicle and can start straight.
5、 Pay attention to driving style/optimize route
When the vehicle is just starting, it should drive slowly and guard against rapid acceleration, otherwise the instantaneous switch will cause the vehicle to form a large current discharge, and the range will naturally be reduced. Generally, it is better to keep driving at 50-80 km/h in urban areas, and try to use economic mode. In addition, for pure electric vehicles, the biggest anxiety in winter comes from the range mileage, so we must control the driving distance according to the current range mileage and optimize the route in advance, otherwise when the power is used up, we will have to wait for the trailer rescue.
