How to use new energy vehicles is reliable?

In recent years, with the rapid development of new energy vehicles, the global sales of electric vehicles have continued to grow. According to the latest production and sales data of China Automobile Industry Association, in February this year, the production and sales of new energy vehicles in China reached124,000 and 1 1000 respectively, increasing by 7.2 times and 5.8 times year-on-year, setting a new production and sales record.

At the first Green Car Conference and Green Life Week, when people buy new energy vehicles, the most concerned issue is still battery and battery life.

According to statistics, by the end of this year 1, 936 1 new energy vehicles have been included in the safety early warning platform of new energy vehicles of China Automotive Engineering Research Institute. The platform relies on emerging technologies such as big data, cloud computing and artificial intelligence. And through the real-time monitoring of vehicles, the three-level hierarchical alarm of vehicle faults is realized, making vehicles safer.

According to the analysis of vehicle fault alarm connected to the safety early warning platform of new energy vehicles, the most common vehicle fault alarm is "single battery overvoltage alarm".

How to scientifically use new energy vehicles to ensure longer battery life?

Zhang Yu, an engineer in the data center of China Automotive Engineering Research Institute, gave these suggestions:

● When charging

The charging of new energy vehicles should be mainly based on slow charging, supplemented by fast charging, which can effectively extend the battery life. When charging new energy vehicles, avoid battery Wally, and the battery charging amount should be controlled at about 90%; Wally once a month, so that the battery management system can correct itself.

When charging a vehicle in cold weather in winter, if the vehicle itself does not have a thermal management system, it should be warmed up before charging the vehicle.

● When driving.

Try to avoid stepping on the accelerator to accelerate when driving, and avoid irreversible damage to the battery caused by large current discharge.

When it is found that the continuous mileage drops by more than ten kilometers in a short time, it may be that the battery is damaged and should be repaired in time.

Regular maintenance, especially when the chassis has friction, should go to a regular 4S shop for inspection as soon as possible. Pay attention to the inspection of the charging port after the vehicle experiences heavy rain and outdoor bumps.

● When the vehicle is placed for a long time.

The battery has self-discharge. If you don't drive for a long time, you should pay attention to keeping the vehicle battery above 30%. If the vehicle battery is in a zero state for a long time, it will cause damage to the battery.

After buying a new energy vehicle, how can I apply for installing charging pile equipment in my parking space?

"I want to change new energy vehicles, but I am afraid of the trouble of installing charging piles." At the exhibition site, the installation of charging piles has also become a concern of many citizens.

In this regard, the State Grid staff introduced that the installation applicant must first prepare the original and photocopy of the resident ID card of the parking space owner, the original and photocopy of the fixed parking space title certificate, the certification materials issued by the property agreeing to use the charging and replacing facilities, and the charging pile nameplate information. In addition to the above materials, the agent's ID card and the power of attorney of the property owner are also required.

After that, you can apply through the State Grid APP, or you can apply in the State Grid Business Hall. After receiving the application, the power company will send personnel to the site to have a look and install the electric meter. After that, the applicant installs the purchased charging pile equipment, and finally, the power department carries out acceptance and electrification.

The battery of the electric car is running out. How to find a nearby charging pile?

Drive the charging car on the road. The battery in the car is dying. Can you find the charging pile in time? Can you charge when you run at high speed?

For the charging and battery life of new energy vehicles that many citizens care about, Mr. Qu, the owner of new energy vehicles, said that when the battery of new energy vehicles is running out, a charging alarm reminder will be sent to the owner. Car owners can find nearby charging piles to charge their cars through mobile navigation.

According to the data from State Grid Chongqing Electric Power Company, as the earliest, largest and most functional vehicle-pile integration platform in China, by the end of 20 19, "e Chongqing" had connected more than 40 new energy vehicle brands, more than 50,000 vehicles, more than 70 charging operators and more than 3,000 charging piles, making it convenient for new energy vehicles to find nearby charging piles in time for battery life.

In addition, Chongqing has built more than 100 expressway charging stations around the city, Chongqing-Chengdu, Chongqing-Shanghai, Chongqing-Sui, Chongqing-Kunming, Chongqing-Neighboring, Chongqing-Guizhou, Jiang Yan, Baomao and Blue Ocean, which is convenient for new energy owners to charge for a long time.

In order to help consumers better understand and choose new energy vehicles when buying a car, Chongqing's first Green Car Conference and Green Life Week came into being. According to the relevant person in charge of the event organizer, more than 30 new energy vehicles of 13 brand were displayed at the Green Car Conference, and the car prices ranged from 70,000 yuan to 600,000 yuan.

In addition to understanding the new energy vehicles of Mercedes-Benz, BMW, Audi, Weilai, Tesla, BYD, Tucki, Euler, Wuling, Geometry, Lectra, Chevrolet and other brands, there are also professionals who provide on-site consultation to help choose cars and bargain.

The first Green Car Conference also set up a gift punching session. Visitors only need to visit three new energy vehicle booths and stamp them, and they will have the opportunity to randomly select exquisite gifts such as Singapore Commune home art paintings, pillows, Tesla customized T-shirts, and environmental protection bags.

In order to let visitors know more about new energy vehicles, we consulted the automobile inspection experts of China Automotive Engineering Research Institute on the spot, and gave professional answers on battery safety, energy efficiency evaluation, common faults and other issues.
