Development of new energy vehicles must be complemented by battery technology shortcomings

With the promotion of policies and the release of market demand, new energy vehicles have seen a boom in production and sales in China in recent years. However, in the eyes of some consumers, new energy vehicles are just “looking beautiful.” They are discouraged by factors such as high car prices, difficulty in charging, safety and driving performance and the gap between traditional fuel vehicles. In this regard, some insiders suggested that the promotion of new energy vehicles must break the battery technology shortcomings.

Development of new energy vehicles must be made up Battery technology short board

When the reporter saw the Wuhan citizen Hui Yucheng, he was leading a second-hand car agent to inspect the car. He plans to sell a new energy car. “There is no place to charge at home and in the unit. It is always too much trouble to charge outside. It costs more than 20 yuan for a charge. It takes too much time for a slow charge to take four or five hours.”

July 2017 Hui Yucheng heard that buying new energy vehicles can enjoy national and local financial subsidies, and exemption from taxation and bridge and tunnel ETC tolls. Hui Yucheng and his wife decided to buy a pure electric vehicle as a means of transportation, and buy a car and insurance. It cost more than 70,000 yuan. “The merchant promised to send the charging pile and find someone to install it for us. At that time, I wanted to install it in the community or the unit. I didn’t expect the unit and the community to say that other owners had opinions that they disagreed with the installation. Now they can only sell it.” Hui Yucheng said.

Mr. Chen, the owner of Wuhan New Energy Vehicles, also spit out. Although it only costs a few cents to charge at home, it is inconvenient to install parking spaces and charging piles in older districts. At one time, the electricity was 1.5 yuan, and the charge was 30 yuan. Once calculated, the advantage of low cost of using new energy vehicles is not obvious.

The reporter found that compared with gasoline vehicles of the same price, the details of “appearance of the vehicle”, “work in the interior space” and “mainstream configuration” directly affected consumers’ evaluation of new energy vehicles.

Yang Weimin, a citizen of Wuhu, Anhui Province, is a logistics company employee with a traditional fuel vehicle and a domestic new energy vehicle. Because the logistics company has charging piles, Yang Weimin now basically opens new energy vehicles every day. But the Peugeot car he still has to keep. “Returning to the old home has to open a fuel car.” Comparing the two cars, Yang Weimin feels that the driving experience and safety performance of the new energy car are relatively poor.

“The speed is about sixty kilometers per hour, and there is no sustained acceleration in the back of the gasoline car. There is no power in the speed of eighty or ninety kilometers.” He said that for the pursuit of driving experience. For young people, the performance appeal of new energy vehicles is now relatively low. Most of the colleagues around him drive new energy vehicles, but no one dares to drive high speed. “The motor is noisy, and it is worried that the battery life is not enough. If you open it, you can’t get back.”

At present, the mileage of pure electric new energy vehicles is generally less than 400 kilometers, and the cruising range of most models is less than 300. Kilometers, most of the winter cruising range will be greatly reduced. “The battery life is 300 kilometers, the winter is warm, and the battery life is half.” A Beijing car owner spent about 150,000 yuan at the beginning of this year to purchase a pure electric car with “smart temperature control system”, but “end of life” and “warm” “Can’t have both.

It is understood that there are still a large number of new energy vehicles using lead-acid batteries, which are traditional batteries, because the energy density is small, to ensure a certain endurance capacity, the volume and quality should be made very large. . Therefore, users often encounter the dilemma of having to push the cart when the battery is low. But now, ternary lithium batteries with higher energy density have gradually replaced lead-acid batteries as the mainstream of new energy vehicle power batteries, but considering the high cost of ternary lithium batteries, some auto manufacturers still maintain their cruising range at three. About four hundred kilometers.

In addition, new energy vehicles often encounter some “unacceptable” situations during their use.

When the reporter drove a new energy-strapped car with a green card in Chengdu, he encountered a situation in which some new energy vehicles in the parking lot could not enter. The parking lot charge said that the license plate recognition system is still unable to identify the new energy car number plate.

Shenzhen Changying is a smart license plate recognition system service provider. The person in charge of the company’s technical staff introduced that to solve this problem, we must wait for the original system to be upgraded and optimized.
