      4. Technology development is the proportion of power consumption and battery kilometer subsidy standards meet the right direction of electric cars
        2018.10.10 Pageview:353

        2016 announced the first two batches of new energy vehicles to promote the application of the recommended directory, including passenger cars and commercial vehicles, including a total of 466 models to enter the directory. But does not contain a pure electric vehicle models.

        In the previously announced the 6 batch of purchase tax exemption list, a total of 362 pure electric vehicles, including special transport vehicles up to 219, the special class of special vehicles up to 143. And the corresponding to meet the new energy vehicles, trucks recommended models technical requirements of only 36 models, the standard rate of only 10%. Among them, special vehicle models only 21 models, special transport vehicles 15. (source: first electric network, Liu Wanxiang, 2016-04-01)

        Suzhou DSM Green Power Co.Ltd. chairman and chief technology officer Dr. Wu Deping (Dr. Walter Wu),said that this is which is the countries are expected to take to promote the pure electric vehicle special vehicle factory to strengthen technology development results, the lack of technical capacity only by increasing the battery capacity to achieve mileage requirements of the car factory in support of the exclusion list. In order to meet these new requirements, lightweight design and development of the body will play a major role, but only a few domestic car plant has the relevant technology. For most cars, the other way is to reduce the battery capacity, but will continue to drive a sharp reduction in mileage, making the mileage anxiety problem even worse. An economically viable solution is to reduce the battery capacity by adding a small, economical and reliable vehicle mounted DC power generation system (range extender).

        Compared with the pure electric vehicle, the range extender has a lot of advantages for pure electric drive vehicles:

        1, “Completely solve the use of pure electric vehicles mileage anxiety";

        2, When in summer, open air conditioning, is no longer worried about the impact of driving range;

        3, When in winter, battery discharge capacity decreased sharply, driving range can be reduced by about 50%. At the same time warm air will further reduce the mileage, a range extender will not have to worry about these problems;

        4, The market is now on the car with the lithium battery warranty for 5 years or more, but most of the battery PACK in fact, the technical level is very low, 2-3 years may need to be replaced. This involves the replacement of the battery of the risk (no subsidy), is a lot of car plants do not want to face. The addition of extender will greatly prolong the service life of battery (to reduce the large current discharge, ensure that the battery will not be released).

        Dr. Wu Deping pointed out that: electric cars since it is a tool to make money, turn out rate is the main competition index. The installation of a range extender electric car, the driving rate will be greatly improved, the market will welcome! Now most of the car factory are concentrated on electric cars, but because of subsidies after the purchase cost is low, the user will not be too much concerned about the future of the car when using the driving rate problem. But once the user really use them, driving rate is more and more obvious indicators!

        As the first electric analysis, the majority of electric vehicles will not meet the new national standards for subsidies and subsidies, so that the current stage of these vehicles into an embarrassing situation. Adopting what kind of technical route to meet the new standards will affect the development and even survival of most car factories in 2016, which need to be paid enough attention to.
