What should I do if the battery of the electric car in winter is not enough?

As the temperature decreases, the mileage of new energy vehicles is affected more or less. Although the phenomenon in this industry has been accepted by consumers, how much do you know about how to effectively extend the mileage of new energy vehicles in the winter? In fact, through good car habits, it is equally easy to open a new energy car in winter.

Battery life is the key to winter battery life

To extend the cruising range of an electric car, you first need to know the main factors. Experts explained that the cruising range of electric vehicles in low temperature environment will be reduced to a certain extent the key reason is the power supply principle of the power battery. When the temperature is higher, the battery is more energetic, and the battery's charge and discharge performance is better. On the contrary, when the temperature is lower, the battery activity is affected, and the charge and discharge performance will decrease. This is a case where we use other electronic products in winter reason. For example, when we travel to cold regions such as the Eastern Three Provinces in winter, the digital camera takes a few shots and will take it to your arms for a while, otherwise the camera will automatically shut down and cannot shoot; the iPhone is the absolute overlord in the mobile phone industry, when used outdoors in winter. There will also be sudden sudden blackouts or increased power outages.

On the other hand, the frequency of using air-conditioning hot air in the cabin in winter is greatly increased. The battery energy causes the energy of the driving vehicle to decrease, which makes the cruising range in winter generally affected. The data shows that the range of new energy vehicles in winter is generally 10-20%, which is equivalent to 15km-30km. It is a common normal phenomenon to differ from other seasons. This is not only the new energy in China. The automobile industry also exists in the giant electric vehicle companies such as Europe and the United States, and experts say that domestic companies are very high in terms of batteries and electrolytes, and some are even better than foreign countries. Consumers do not have to worry about the quality of the car itself.

Good car habits help long-lasting life

Although the current battery performance is inevitable in the winter, with the continuous improvement of battery technology at home and abroad, the problem of low-temperature performance degradation of the battery will be continuously improved. For the consumers themselves, it is also necessary to pay attention to the car habits on weekdays and pay attention to the protection of the batteries.

Mr. Wang, a driver who has been driving for 8 years, is an electric taxi driver. In the long-term professional driving, Mr. Wang also summarized some of his own little experience in driving new energy vehicles in winter. He mentioned that the battery performance of new energy vehicles in winter will be affected by temperature. The use of charging is a good way to improve the performance of the power battery and extend the cruising range. To this end, Mr. Wang developed the habit of charging immediately after receiving the car every day, and started charging again 1-2 hours before the daily departure. Since the charging is started again, the vehicle charging system will heat up the battery to improve the low temperature performance. “There should be attention to the charging of the vehicle during the driving process,” Mr. Wang added. “The battery temperature of the new energy vehicle increases after a long journey. At this time, the charging can increase the charging speed and ensure the charging speed effective charging of the vehicle."

For Mr. Wang's approach, industry experts agree that the performance of the battery is closely related to the owner's method of use. Good car habits play an important role in extending the cruising range of electric vehicles. In Mr. Wang’s car experience, the experts also put forward some tips that ordinary users don’t know. For example, before the user drives, fully open the warm air for 10 minutes, accelerate the battery temperature increase, and then insert the gun to charge, which will greatly improve the charging speed and improve the charging performance. Because the vehicle is charged when the battery temperature is low, the vehicle charging system heats up the battery and can be charged after reaching a certain temperature, which will prolong the charging time and reduce the charging performance. The owners can also try to adjust the temperature to the highest when heating, and the wind speed is adjusted to 2 or 3, which can save battery energy 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 affect the cruising range to a certain extent.

Ouyang Minggao, executive vice president of China Electric Vehicles 100-members, argued from the perspective of electrochemical characteristics: the battery is an electrochemical power source, and it has many characteristics that are different from those of the engine. There are changes in spring, summer, autumn and winter, and the performance is degraded when the temperature is low will affect battery life. The driving style is different and the driving range will change. If you step on the gas pedal and the discharge rate is quite large, the power will be released. The bigger the electric car the bigger the change is. For example, Tesla, if it is driven by motion, it will last for 480 kilometers, and the sport mode can only last for more than 200 kilometers. This is the characteristics and law of the electrochemical power source itself.

Also, experts have studied the attenuation of batteries or vehicles during normal storage. The results show that the battery's power will gradually decrease even if the vehicle is not running statically. Therefore, it is necessary to correctly understand the performance of the electric vehicle, and pay attention to the maintenance and use methods during use to achieve the optimal cruising range.

At present, China has long-lasting mileage technology, but from the perspective of China's transportation system, China's electric vehicles do not have to extend more than 500 kilometers of pure electric vehicles like the United States, which is not suitable for domestic development from the perspective of popularization. "Approximately 300 kilometers of electric vehicles will be a normal state by 2020. But it must be mentioned that the battery life is 500 kilometers, which can be realized technically, but it will increase the cost. For every 100 kilometers of battery life, the price will increase by at least 10,000 yuan. The above, it is difficult to reduce the price of the car, which increases the difficulty of promotion." Ouyang Minggao, executive vice president of the China Electric Vehicle 100-members, does not advocate excessive requirements for pure electric vehicles.

I believe that in the near future, more and more owners will join the ranks of new energy vehicles. Really understanding new energy vehicles and mastering the right methods will help consumers to better use their cars, improve driving pleasure and ride experience, and enjoy convenient car life.
