As the temperature drops, the cruising range of new energy vehicles is more or less affected. Although the phenomenon in this industry has been accepted by consumers, how much do you know about how to effectively extend the cruising range of new energy vehicles in winter? In fact, through good car usage habits, driving a new energy car in winter can be as handy as possible.
Winter endurance, battery performance is the key
To extend the range of electric vehicles, first you need to know the main influencing factors. Experts explained that the cruising range of electric vehicles will decrease to a certain extent in low temperature environments. The key reason lies in the power supply principle of the power battery. When the temperature is higher, the battery`s vitality is stronger, and the battery`s charge and discharge performance is better. On the contrary, when the temperature is lower, the battery`s activity is affected and the charge and discharge performance will decrease. This is the same as when we use other electronic products in winter. reason. For example, when we travel to cold regions such as the Three Eastern Provinces in winter, we need to hold the digital camera in our arms for a while, otherwise the camera will automatically shut down and be unable to take pictures; iPhone, as the absolute overlord of the mobile phone industry, is used outdoors in winter There will also be situations such as sudden loss of power or increased power loss.
On the other hand, in winter, the frequency of using air-conditioning hot air in the cabin has increased significantly, and the battery energy for heating the cabin has caused a reduction in the energy to drive the vehicle, which generally affects the cruising range in winter. The data shows that the range of the cruising range of new energy vehicles in winter is generally reduced by 10-20%, which is equivalent to about 15km-30km. It is a common normal phenomenon that the cruising capacity of other seasons is different. This is not only in my country's new energy The automobile industry also exists in the European and American giants of electric vehicle companies, and experts say that domestic companies have high levels of batteries and electrolytes, and some are even better than foreign countries. Consumers do not need to worry about the quality of their cars.
Good car use habits help long-term battery life
Although the current battery performance is inevitably affected in winter, with the continuous advancement of battery technology at home and abroad, the problem of battery low-temperature performance degradation will continue to be improved. As for consumers themselves, they also need to pay attention to their daily car usage habits and pay attention to the protection of batteries.
Mr. Wang, the driver who has been driving for 8 years, is an electric taxi driver. During the long professional driving, Mr. Wang also summed up some of his own experience of driving new energy vehicles in winter. He mentioned that the battery performance of new energy vehicles in winter will be affected by the temperature, and charging on-the-fly is a good way to improve the performance of the power battery and extend the cruising range. For this reason, Mr. Wang has developed the habit of charging immediately after receiving the car every day, and at the same time restarting the charging 1-2 hours before leaving the car every day. Because the charging is started again, the vehicle charging system will heat up the battery, which can improve the low-temperature performance. "It should also be noted that the vehicle is charged during driving." Mr. Wang added, "The temperature of the battery of the new energy vehicle increases after a certain distance. At this time, timely charging can increase the charging speed and ensure Effective charging of the vehicle."
For Mr. Wang's approach, industry experts agree that the performance of the battery is closely related to the way the car owner uses it. Good car usage habits play an important role in extending the range of electric vehicles. Based on Mr. Wang's car experience, experts have even put forward some tips that ordinary users don't know. For example, before driving, the user should turn on the warm air for 10 minutes to accelerate the increase in battery temperature, and then plug in the gun for charging, which will greatly increase the charging speed and improve the charging performance. Because the vehicle is charged when the battery temperature is low, the vehicle charging system will heat up the battery until it reaches a certain temperature, which will extend the charging time and reduce the charging performance. Owners can also try to adjust the temperature to the highest when heating, and the wind speed to 2 or 3 gears, which can save battery energy consumption while heating. This is because the warm air of a pure electric vehicle is heated by electricity. The longer the warm air is used, the faster the energy consumption will be, which will affect the cruising range to a certain extent.
Ouyang Minggao, executive vice chairman of the China Electric Vehicle Association of 100, demonstrated this view from the perspective of electrochemical characteristics: batteries are electrochemical power sources, and they have many characteristics different from those of engines. There are changes in spring, summer, autumn and winter, and performance will decrease when the temperature is low. , Will affect battery life. The driving style is different, the driving range will also change. If you slam on the accelerator and the discharge rate is quite large, the amount of power released will be less. The bigger the electric vehicle, the greater the change. For example, if the Tesla is driven in a sport mode, it would have a range of 480 kilometers, but the sport mode would only have a range of more than 200 kilometers. This is the characteristic and law of the electrochemical power source itself.
In addition, experts have also done research on the attenuation of batteries or vehicles during normal storage. The results show that even when the vehicle is not running and stored statically, the battery power will gradually decay. Therefore, it is necessary to correctly understand the performance of the electric vehicle and pay attention to the maintenance and use during use to achieve the most ideal cruising range.
