At present, the growth rate of the domestic auto market has gradually slowed down, but the performance of new energy vehicles has been noticeable since the beginning of this year, and all car companies have also expounded their swords and launched new products in the new energy auto market.
Industry insiders pointed out that with the favorable policies, auto manufacturers will be more pragmatic in product development, and the introduction of home-based or mid-to-high-end products for different groups of people will continue to subdivide the categories.
New energy vehicles enter the first year of development
According to data from the China Association of Automobile Manufacturers, sales of new energy vehicles have increased nearly threefold in the first three quarters of this year, and sales are expected to exceed 50,000 units this year. The development of new energy vehicles seems to have become a bright spot in the development of the industry this year.
It is reported that domestic production of new energy vehicles mainly include pure electric, plug-in hybrid two categories. The relevant government departments are making greater efforts to introduce a series of policies and regulations that are favorable to the development of new energy vehicles. Following the introduction of the “Catalog of New Energy Vehicles Exempted from Vehicle Purchase Taxes†(first batch) at the end of August, the “Catalogue of New Energy Vehicles Exempted from Vehicle Purchase Taxes†(second batch) was issued at the end of October. New energy passenger cars, including electric hybrids and plug-in hybrids, already have 51 models (23 in the first batch and 28 in the second batch) being included in the scope of free vehicle purchase. At the same time, the state and local subsidies for the purchase of new energy vehicles also allow consumers to gradually avoid the price concerns.
From the perspective of the new energy market, JAC, BAIC, BYD, Dongfeng Nissan Kai Chen, and SAIC Roewe have all given “big strokes†this year and have launched new new energy vehicles or upgraded their technologies on the basis of the original. Jianghuai further upgraded the Yueh series, and on the basis of the launch of iEV4 this year, it actively planned to promote the new iEV5. In addition, BYD Qin, e6, Beiqi's new EV200, Dongfeng Nissan Kai Chen e30, Zhongtai Zhidou and other subdivided new models continuously improved the technical configuration to meet the travel needs of different groups of people.
Good performance of core components
The engine is the core component of the traditional car, but the core component of the new energy car is the battery system. To this end, Jianghuai Yuet iEV4 R & D team uses lithium iron phosphate batteries. It is understood that lithium iron phosphate battery as a new generation of lithium battery cathode material, many car companies are using, is currently the mainstream of electric vehicles supporting batteries. The advantages of lithium iron phosphate are very obvious, long life, large charge-discharge rate, good safety, good high temperature, harmless elements, and low cost. For long-term maintenance, the warranty period for iEV4 batteries, motors and electronic control systems is 5 years or 100,000 kilometers.
The life of the battery is the cycle life. The cycle life of the battery is closely related to the cycle state of the battery, such as discharge rate, charge rate, and temperature. The cycle life of the battery laboratory data is usually obtained at a constant charging and discharging rate of 0.3C at a constant temperature of 20 degrees. From the above experimental data, it can be seen that the cycle times of the lithium iron phosphate battery are greatly advanced. Lead-acid batteries, even compared to ordinary lithium-ion batteries 600-1000 cycles, there are obvious advantages. JAC and Wyatt IEV4 electric vehicle core electric drive components warranty for 5 years or 100,000 kilometers, the actual vehicle test 100,000 kilometers after the battery attenuation within 20%, almost the same as the entire vehicle life.
Practical cost control concept
For electric vehicles, cruising range is the key to the problem and an important indicator that consumers value. “The length of the cruising range should be based on the specific market conditions. At present, R&D personnel are targeting sales targets at a daily life radius of approximately 15 to 20 kilometers. Therefore, there is no need to achieve the ultimate in cruising range. The capacity can be controlled. At the same time, the reduction of the battery weight will also greatly reduce the design difficulty and manufacturing cost of the suspension and steering mechanisms, which will help control the cost of the vehicle.†Jianghuai R&D personnel said.
Fast multi-port charging
In charging time, it takes 8 hours for the Heyue iEV4 electric car to charge using a slow charging port, and 2.5 hours for a fast charging port. At the same time, in order to meet the requirements of different charging piles, the iEV4 is equipped with two types of charging cables, which can meet the two charging methods of the national grid charging pile and household 220V air conditioning socket.
Low price policy support
In the country, we can enjoy both national and local double subsidies as well as a series of local subsidy measures for electric vehicles. Taking the Beijing area as an example, the Heyue iEV4 electric vehicle enjoys dual subsidies from the state and Beijing. The subsidy amount is 95,000 yuan, which means that your car purchase price is 74,800 yuan after subtracting the subsidy amount. Moreover, according to the latest policy of New Energy, the car purchase tax can be exempted for the car purchase. Finally, because it is a new energy model, it is possible to obtain a separate Yaohao qualification in Beijing, and the probability of winning this Yaohao is far greater than that of ordinary household cars.
