From the R&D layout in 2008 to 20 14, new energy vehicles began to enter the family, and now new energy vehicles have been accepted by more people, and their sales account for an increasing proportion.
The emergence of this list is logical, which is also a milestone in the new energy industry. So what is the value of this list from the perspective of ordinary consumers? Different from the very mature "Top Ten Engines" list, the author thinks that the significance of the "Top Ten New Energy" list to consumers is more to convey the development trend of new energy technologies. Then, let's take a look at the new energy power on the list. Which power has the highest gold content?
Pure electricity is dominant, supplemented by mixing.
First of all, we can intuitively see the choice of new energy industry. Among the top ten new energy power systems, seven are pure electric, three are hybrid, and the three hybrid can be divided into two types: plug-in hybrid and 1 extended range hybrid. It can be seen that in the current layout of new energy industry, pure electricity occupies an absolute dominant position, and pure electricity is also considered by more enterprises as the main direction of new energy.
At the same time, hybrid power also occupies a significant proportion in the list. This high probability is caused by the imperfection of pure electric technology at present. Because the cruising range is not enough to support a trip, the charging time even exceeds the time required for eating a meal. Therefore, although the current pure electric vehicle can meet the needs of urban commuting, it is not convenient for long-distance self-driving. Therefore, the hybrid that can eliminate mileage anxiety is regarded by many manufacturers as the best choice in the transition period, and some manufacturers think that hybrid is the best choice.
In the mixed-race camp, it is divided into several small branches. One is plug-in hybrid, which is also the choice of most hybrid manufacturers; The second is the extended-range hybrid, and the models still on sale come from two manufacturers; Third, there is a strong mixture of oil and electricity, mainly led by Toyota and Honda, and other manufacturers rarely participate.
Next, let's take a look at these new energy sources and their highlights on the list.
The first paragraph
Hongqi FME 1.0 pure electric platform system;
Recommended model: Hongqi E-HS9
Highlight technology:?
Equipped with this system? Hongqi E-HS9 is a high-performance, large-size flagship pure electric SUV built by its own brand, and its performance parameters are also very good. With the support of front and rear double motors, its acceleration time of 100 kilometers is only 4.8 seconds, and the cruising range of NEDC with high endurance is 5 10km. But technically, this power platform uses the mature products of the upstream industrial chain, and there is no core self-developed technology. ?
Second paragraph?
BYD integrated intelligent drive system;
Recommended model: BYD? Han EV
Highlight technology: blade power supply?
BYD's integrated intelligent drive system should be the most distinctive of the top ten new energy sources on the list. Instead of using the mainstream ternary lithium battery in the industry, the packaging process of lithium iron phosphate battery was optimized and named as blade battery. The problem of low energy density of lithium iron phosphate battery is improved, and the cruising range of Korean electric vehicles equipped with blade batteries reaches 605km. Not only the technology is unique, but also the performance is excellent. ?
Third paragraph?
GAC New Energy is the world's first "three in one" electric drive system.
Recommended model: Ian v.
Bright spot technology: intelligent battery temperature control system
Aian V equipped with this system is also a star product, and its overall design is very distinctive. Although the core components such as the drive motor and the power battery pack all come from the upstream supply chain, GAC New Energy has also laid out a self-developed intelligent battery temperature control system in the whole electric drive system. This technology is of great help to the safety of the whole electric drive system. In the system with ternary lithium battery as power battery, high temperature and low temperature are both unfavorable factors affecting battery performance. With the intelligent battery temperature control system, the whole electric drive system will work more safely and efficiently. ?
The fourth paragraph?
Jiang Qichun electric drive system
Recommended model: Si Hao E50A
Highlight technology:?
Relatively speaking, the pure electric drive system in Jiang Qi doesn't have many bright technologies worth reading. Although its power density reaches 1.7kW/kg, its core components all come from the upstream industrial chain without exception. The technical level is good, but it is not independent research and development. ?
Section 5?
Dongfeng Peugeot High Performance Electric Drive System
Recommended model: e2008
Highlight technology:?
Although it comes from a joint venture brand, Dongfeng Peugeot's high-performance electric drive system still does not have many exclusive patented technologies, and the core components are still purchased from the industrial chain. The design of e2008 has many bright spots, for example, it uses lighter materials, thus improving the maneuverability and cruising range.
Section 6?
XP-POWER？ 3.0
Recommended model: Tucki P7
Highlight technology: NEDC has a longest cruising range of 706km.
Tucki P7 is a very interesting car with long cruising range and excellent performance. But like most new energy vehicles, the components used in its electric drive system come from the upstream industrial chain. What is commendable is that it uses high-end products from the upstream industrial chain, so its cruising range and performance are excellent. Especially the acceleration performance, the acceleration time of 100 kilometers is only 4.3 seconds. ?
Section 7?
HozonEPT2.0 system
Recommended model: Nezha U? U chuangban
Highlight technology:?
Nezha U is a product that is very close to the people, and its overall pricing is not high, so it is a relatively entry-level product. In terms of core product technology, its electric drive system also comes from the upstream industrial chain, among which the 8 1 1NCM battery of Contemporary Amp Technology Co., Ltd. is the highlight, with the energy density as high as 180wh/kg. However, like most similar products, manufacturers have not mastered more unique self-developed technologies. ?
Section 8?
Tengshi plug-in hybrid power system
Recommended model: the new Tengshi X plug-in hybrid SUV
Highlight technology: electronically controlled four-wheel drive
The core technology of Tengshi plug-in hybrid system comes from BYD. Similar to BYD's plug-in hybrid vehicle, the engine and the driving motor are connected in parallel, so the engine can only drive the front wheel and the rear wheel is equipped with a motor, thus realizing the electrically controlled four-wheel drive. Although such a four-wheel drive structure is unlikely to improve off-road performance, it can effectively improve the driving stability of paved roads. ?
Section 9?
Buick Emotional Plug-in Hybrid Power System
Recommended model: Buick? Light blue 6 plug-in hybrid vehicle
Highlight technology: E-CVT gearbox integrates dual-drive motors and dual-row planetary gear sets.
Buick eMotion plug-in hybrid power system is a representative new energy technology in the joint venture brand, which is characterized by directly integrating two drive motors into the gearbox, so that the engine and the drive motors can simultaneously contribute. This is why it only uses a naturally aspirated engine of 1.5L, but its power performance is very strong. ?
Section ten?
Ideal extended range power system
Recommended model: Li Yi.
Highlight technology: extender mixing
In the whole new energy industry, Ideal is a very maverick, because only a few companies in the whole industry are doing extended-range mixing, and only two are still selling. Its concept, like plug-in hybrid, is to solve mileage anxiety. But its mechanical structure is simpler, and it is essentially a pure electric vehicle, only with an engine for generating electricity. So power matching is much more convenient. Like other new energy brands, its core components such as engines and batteries still come from the upstream industrial chain.
Let's talk about it finally.
From the list of new energy power systems, the development of new energy technologies is diversified at present. Many manufacturers of independent brands, such as BYD, have mastered more important core technologies, but at the same time, we can also see that the upstream industrial chain has a great influence on the whole new energy industry. Most enterprises have not mastered their own core patents in new energy technology, and the procurement and assembly of core components are still the mainstream.
This is not to say that such an industry is not ecologically good. Just like the smart phone industry, whether the operating system or CPU architecture, or even the mainstream CPU is in the hands of 1 or a few enterprises, what downstream enterprises need to do becomes simple, and they can make products with good performance without too high a threshold. For example, hammer mobile phone, Lao Luocan made mainstream products in just a few months. The current new energy automobile industry also has such a situation.
But this is a double-edged sword, highly dependent on the industrial chain. Downstream enterprises have little say in the development of the whole industry. How to develop the industry in the future has become an arbitrary thing for upstream enterprises. At the same time, the homogenization of products is very serious, and the whole automobile market will gradually lose its diversified characteristics.
Therefore, from the author's personal point of view, I still hope that car companies can make more efforts in research and development and make more differences in technology!
