“After releasing the restrictions on licensing, the sales of new energy vehicles are satisfactory, and there are also unsatisfactory places. The satisfaction is that the speed of the overall work is good, and the unsatisfactory place is the demands of the people and the government’s requirements. There is still a gap.On the layout of charging piles, consumer awareness of electric vehicles and the degree of supporting policies need to be further improved. "There are leaders of relevant departments of new energy vehicles who are unwilling to be named are interviewed by "Securities Daily" reporters. Said. At present, the problem of charging piles plaguing the development of new energy vehicles is still a long-standing problem. "At the moment, it is still a charging pile problem," he said frankly.
New Energy Vehicle Quality Improvement
"Anything from scratch, there is always a perfect process, and it is impossible to have no shortcomings when it comes up. In the manufacturing of new energy vehicles, car companies are still active, and they also listen to opinions and suggestions from all sectors of society. In terms of improvement, my overall feeling is that the quality of the car is getting better and better, "said the above sources.
It is understood that in the "Innovation journey - 2014 New Energy Vehicle Miles" campaign led by the Ministry of Science and Technology, supported by the Shanghai Science and Technology Commission, and led by SAIC, each new energy vehicle has undergone a "quality test". .
Among them, besides BAIC and BYD's new energy vehicles, SAIC's Roewe 550PLUG-IN, Roewe E50 and Roewe 750 fuel cell sedan participated in the event, starting from Shanghai to enter Beijing via various road conditions.
It is understood that the Roewe 550PLUG-IN plug-in hybrid sedan is the first mass-produced triple-core plug-in hybrid vehicle in China, achieving a fuel consumption of 2.3 liters per 100 kilometers. Under the comprehensive conditions, the vehicle's pure electric cruising range is 58 kilometers, and the integrated cruising range of oil and gas is 500 kilometers.
Roewe E50 is a purely electric vehicle independently developed by SAIC and has a cruising range of 120 kilometers and a top speed of 130 kilometers per hour. The Roewe 750 fuel cell car adopts hydrogen as fuel, and has arranged two hydrogen bottles with a hydrogen storage capacity of up to 4.34 kilograms. This ensures that the vehicle's constant driving range can reach 400 kilometers and can be started at minus 20 degrees Celsius.
It can be said that the above activities are a good test of the performance of the three Roewe cars. “The entire parade will last for three months and will pass through 25 cities in 14 provinces, municipalities and autonomous regions across the country, and will hold events in 15 cities. The itinerary plans to exceed 10,000 kilometers across the country, including various terrains, to fully test new energy vehicles. A variety of climate, road conditions, altitude and other natural environment adaptability and component performance and technical indicators. "Relevant activities, said the person in charge.
Perfecting the package is still a top priority
"We can't design a perfect thing in the early design process. It always needs a process." The person in charge of the above-mentioned new energy vehicle department told reporters that the government's policy has also been supported, but not enough. "Like charging, the development of new energy vehicles will require the construction of more charging piles in public areas."
So, why is the construction of charging piles not to force? "Social investment is not enough, and investment is not enough because the investors can't see the benefits. The main reason for not seeing the benefits is that the policies are not enough. From this perspective, the improvement of supporting facilities also requires government support, making social funds willing to invest." Indicated.
He said frankly that the prospect of developing charging piles is good, but there is no local construction is still a key issue and the business model has not been well thought out. "From the perspective of work promotion, it is positive. From the perspective of final performance, it is still not enough. We are dreaming about this matter and we hope to quickly promote the construction of the charging pile."
Product modeling and design ability has been greatly improved, but after the completion of product design, before mass production, we must make samples to express the design idea, quickly obtain the feedback information of product design, and evaluate and demonstrate the feasibility of product design. In today's increasingly fierce market competition, time is benefit. In order to improve the competitiveness of the product market, the whole process from product development to mass production is urgently required to reduce the cost and improve the speed. The emergence of rapid prototyping technology provides an effective way to solve this problem, and has attracted much attention at home and abroad
