Pure electric development platform of struggle: to improve or build a new tradition

"SAIC pure electric cars are developed on a new platform." November 20, vice president and general manager of SAIC Passenger Vehicle Company Xiaoqiu said in an interview with 21st Century Business Herald reporter interviewed, although higher input costs to develop new platform , development time is also longer, but in the long run, this is the road we must take the development of high performance electric vehicles.
State support the attitude of the new energy vehicles become increasingly clear that the Guangzhou auto show has become a new energy, "Feast." Especially the autonomous car prices, almost every family announced its own new energy plan, the basic plug-in contains a strong mix of pure electric vehicles.
Plug-strong mixing due to the battery occupied less space, and also have the traditional car features, so almost every family has launched, and the products are developed on a conventional car platform. The pure electric car, then gradually develop into new platforms and prototype development of a traditional car two routes.
Xiaoqiu think development of new platforms, in order to constantly improve the performance of pure electric seamless. And with Beijing Automotive, JAC, Chery car prices, represented by its pure electric products, basically we have a prototype.
Deputy general manager of JAC marketing company Zhangjin Han believes that the popularity of the electric car is the most crucial cost and development in the production prototype, based on energy cost optimization. If electric cars can not share parts and mass production car, the size is difficult to expand in the long term disadvantage.
There is also the route in between. Geely Institute president Feng Qing Feng told reporters: "Geely high-end electric cars in the Imperial platform development, and the development of small electric vehicles is a new platform."
250 km endurance requires a new platform?
"SAIC electric car in 2017 before listing, but we hope to be able to become the benchmark after it listed." SAIC insiders told reporters that the enterprise pure electric vehicle positioning, namely the outset targeting the high-end.
Although SAIC Roewe e50 currently only an electric car, but because of the overpriced, sales are not mainstream, but SAIC layout of the electric car is not slack. In its pure electric vehicle product plan, the pure electric SUV, A-class cars and high-performance SUV has a plan. Wherein the high-performance SUV will rival directly at the Tesla. However, only the performance of the standard, the price will be lower than a lot of Tesla.
"Now a new pure electric car project, if the mileage is not more than 250 km, do not dare come out." Deputy director of the technical center of SAIC Passenger Vehicle Company, Dresdner Zhu, general manager, said more than 250 km Mileage , we must develop a new platform in order to truly solve the limitations of the development of pure electric vehicles in the traditional car platform.
If the development of higher mileage of pure electric vehicles in the traditional car platform, because the higher the mileage, the more battery usage, while traditional vehicles vulnerable to various expansion chassis space restrictions, it is possible to have a seat ground clearance is too short, head space is too small, or the trunk is reduced and other issues.
Tesla now better sales, the BMW i3, high mileage of electric vehicles, are developed on a new platform.
Traditional platforms can quickly reduce costs?
"Developing a new platform and platform developed using existing models are not antagonistic." Zhangjin Han told reporters, just choose between the two different development methods.
JAC iev5 pure electric vehicles, for example, although it is a tradition in the development of the JAC unlisted A-class car platform, but because of the electric car and the traditional characteristics of different car, so the car has also been tuned chassis, in full accordance with the positive process development .
"Compared with the traditional car, bearing a pure electric vehicle around a more uniform, the electric steering does not require intake and exhaust, the car is completely different with the traditional arrangement, with wading, thermal management and other systems, with fuel vehicles is completely different, so the positive Developer is required. "Zhangjin Han said.
JAC electric cars also have to share the platform with the traditional car. For example, the car looks, if separate development, not only face high design, tooling costs, and cost-sharing products is also high, is not conducive to price of electric cars will become closer.
The cross-car prices also mostly take the electric car and the traditional car sharing platform. Such as the Nissan Leaf, and Tiida same platform as the VW Golf places prototype build e golf.
Zhangjin Han think, from the trend, the competitiveness of electric vehicles is reflected at the end of subsidies, are there markets. If the mileage of 300 km of electric vehicles, in the absence of subsidies, the prices of control in less than 100,000 yuan, the future will be highly competitive market.
Judging from the mileage, although Mr.zhang agree a new platform to have more space for the battery, but he thought of as a meet consumer demand for the use of the electric car, only need to meet a week on one charge, about 300 km Mileage enough.
"Battery technology advances, the ability to quickly upgrade density, such as JAC iev5 use batteries, has gone from 180 watt-hours per kilogram before the upgrade to 240 watts, that is, the same weight of batteries, mileage increase of three per kilogram one-half. "Mr.zhang he said.
President of Geely Automobile Research Institute Feng Qing Feng told reporters: "The existing platform development of electric vehicles affected are mainly lightweight work, the other is not much change." He believes that the development of the new platform, the greater significance is reduced costs, the use of new materials. For example, Tesla uses aluminum body, the BMW i3 use of carbon fiber materials.
However, Xiaoqiu do not think the new development platform will be weakened SAIC in the cost competitiveness. In his view, the electric car and the traditional car, the key to competitiveness lies in scale, SAIC was willing to put real money to develop a new platform made electric car, a very important reason is optimistic about the future of the electric car market.
"The future of the relationship between electric vehicles and conventional vehicles, like the relationship between the lighters and matches." Xiaoqiu slightly humorous to say that SAIC was willing to generous investment from the outset, because I believe the future of electric cars just as the popularity of lighter, pre- cost development platform entirely be apportioned out.
