At the 2014 Road Transport Exhibition, the pure electric buses exhibited exhibited two characteristics: First, the three types of charging models, fast charging, slow charging, and power changing, co-existed, among which the fast-charging passenger cars appeared together and occupied half of the total number of pure electric buses; The second is that small and medium-sized pure electric passenger cars with a height of 8 meters are rising. Keywords: pure electric passenger car new energy bus 2014 Road Transport Exhibition, the exhibition of pure electric passenger vehicles presents two characteristics: First, fast charging, slow charging, changing the three types of charging modes coexist, including fast charging passenger cars to make a debut, occupy Half of the total number of pure electric passenger vehicles is exhibited; the second is that small and medium-sized pure electric passenger cars with a height of 8 meters are rising.
What are the specific parameters of these pure electric buses? Can these two features become the future development trends of pure electric buses? Please see the report brought by the reporter.
Three charging modes coexist sought <br> <br> fast charging electric bus based on the current market products, the pure electric bus charging mode can be divided into three types: slow charging, fast charging, the battery pack is quickly replaced. The charging time in the slow charging mode is 5-8 hours, and some even reach 10-20 hours. Fast charging charges the battery with a large current for 2 hours. The rapid replacement of the battery pack is accomplished by professionals using mechanical equipment to quickly complete battery replacement, charging, and maintenance.
Vehicles adopting these three types of charging modes have appeared in this year's road transport exhibition. Looking closely, among the 10 pure electric buses on display, 5 are fast-charging pure electric buses with fast-charging lithium batteries, and all of them are 8 meters or less.
Among them, Yutong, Xiamen Jinlong, Futian Ouhui held a press conference to promote their fast-charged new products and exhibited them as the main product of the exhibition. As always, Hengtong Electric supports fast charging technology and exhibits two fast-charging pure electric passenger cars of 6 meters and 8 meters. The collective high-profile debut of fast-charging pure electric buses has caused a lot of attention in the industry. It also seems to convey a signal that the fast-charging mode or the development of pure electric buses will become a major trend in the future.
First of all, Yutong, its E7 fast-charging pure electric bus, has a cruising range of 80-150 kilometers. Under a voltage of 380V, it can be filled with 1 hour of fast charge, and slow charging takes 3 hours. E7 also supports 220V civilian voltage charging, but the charging time will be extended to 8-10 hours.
Xiamen Golden Dragon XMQ6641AGBEV and Fotonauhui BJ6650 are also fast-charging pure electric buses. In the fast charge mode, the former can be fully charged in 15 minutes, while the latter is fully charged in 8-15 minutes. Both have a single charge mileage of about 100 kilometers. .
In addition to these three companies, Hengtong Electric Co., Ltd., which has been relying mainly on fast charging mode, has naturally not lagged behind. It has exhibited two pure electric buses, the 6-meter CKZ6621BEV and the 8-meter CKZ6812HBEV, all adopting fast charging mode. The single charge cruising range of these two vehicles is 80-100km, that is, they need to be quickly recharged for 15 minutes in order to meet all-day operation.
Except for these 5 fast-charged pure electric buses, the remaining 5 models are slow charging and power-changing models using lithium iron phosphate batteries, exhibited by Xiamen Jinlong, Ankai, Nanjing Jinlong and Changlong, and their bodies are all over 10 meters. , And the appearance is quite similar. It is worth mentioning that the 10.7-metre pure electric passenger car displayed by Xiamen Golden Dragon adopts a short rear suspension and battery rear design, which improves the space inside the car and raises the wading depth to 80-100cm. It is a major bright spot design.
The rise of small and medium sized electric buses <br> <br> analyzes the development trend of pure electric bus charging technology, exhibitors look at pure electric passenger car models exhibited in length characteristics: the rise of small and medium sized electric buses.
While battery life still restricts the development of pure electric buses, domestic bus companies are also seeking their own solutions. Is it still insisting that a battery with a weight of more than 10 meters will carry more than 220 kilometers of batteries? Is it still possible to develop small- and medium-size passenger vehicles with a short distance of 6-8 meters to allow them to shuttle freely in the micro-circulation of small areas? Or both go hand in hand to develop together?
At this road transport exhibition, seven bus companies gave their own answers. Ankai, Nanjing Jinlong, Changlong and Yi have chosen the first method. Yutong, Futian Ouhui and Hengtong Electric chose the second way. Xiamen Golden Dragon chose both. From a quantitative point of view, there are 4 pure electric buses over 10 meters in length, and 6 cars under 8 meters in size, which prevails.
Observing the companies exhibiting small and medium-sized pure electric vehicles carefully, Yutong has no need to say that it has occupied the top spot for passenger car sales all the year round. Xiamen Jinlong is also among the top three bus sales. Futian Ouhui and Hengtong Electric both occupy the mainstream bus market in the city. It can be said that the sales of such small and medium-sized electric buses are not a problem for these four bus companies.
On the other hand, under the pressure of 500,000 new energy vehicles, it seems that the promotion of such small and medium-sized passenger vehicles everywhere is also easier. Therefore, such small and medium-sized pure electric buses appear to have certain advantages in marketing. Having said that, the proportion of such small and medium pure electric buses in the future pure electric passenger car market will depend on their specific market performance.
To sum up, the model of pure electric bus displayed at this year's road transport exhibition covers four levels of 6 meters, 8 meters, 10 meters, and 12 meters, and it almost covers the models of conventional power buses, fast and slow charging. The models for the three-electricity change model have also been exhibited, and the trend of diversification and segmentation of pure electric buses is even more pronounced.
At the same time, more than 10 meters of pure electric buses will use multiple battery packs to ensure cruising range of more than 200 kilometers, and use the night slow charge or daytime power exchange mode development; 8 meters and below will use fast charge mode for short-range micro-cycle operation .
The number of buses displayed does not represent market sales, but it has certain reference significance to the market trend. In the end, whether the models pushed by various companies at the auto show can become the mainstream of the market remains to be further observed.
