Shanghai Shenlong’s lightweight hybrid buses, launched in April 2009, have shown great momentum at the Asia Expo. After launching the SLK6121UF1EV Battery + Capacitor Powered Buses, the prelude to the development of purely electric buses was unveiled. This is also the young Shanghai Shen Long for the first time involved in the research and development of pure electric passenger cars, becoming one of the few companies in China that are qualified to carry out new energy bus R&D.
With the global energy supply tending to be tight and the human living environment deteriorating, the international market and the domestic high-end market are in urgent need of bus products with low energy consumption and low emissions. This year, the state has invested a large amount of funds for new energy development and the promotion and application of energy-saving and emission-reduction projects. At the same time, the 2010 Shanghai World Expo also requires the use of energy-saving and environmentally-friendly buses. The state attaches great importance to the urban environment, and the urban environment of major domestic cities such as Beijing and Guangzhou. Governance is also in progress. In such a situation, the number of hybrid electric buses for pure electric vehicles, fuel cells, and diesel vehicles will surely increase significantly. As a result, many star stars of new energy buses have emerged.
In such a domestic and international environment, Shanghai Shen Long, the rising star of the passenger car industry, decided to take the development of new energy buses as its important mission. According to the company's annual development plan, on the basis of existing products, increase technology research and development to fill gaps in existing products, and proceed to develop 12-meter electric bus products. Finally, under the birth of this good situation, Shanghai Shenlong Bus was born another star of environmental protection - SLK6121UF1EV battery + capacitor power bus.
The car adopts a lithium battery + super capacitor power system independently developed by Shanghai Ruihua Group. The super capacitor has the advantages of quick charge, no memory charge/discharge, high number of charge/discharge cycles, and no secondary pollution, but has the disadvantage of rapid discharge; the lithium battery has the advantages of large storage capacity and long storage time, but the charging time is compared. long. This set of power system not only takes the length of the two, but also achieves an effect of 1+1 greater than 2. In addition to the advantages of "electrical oil replacement" and "zero emission" of conventional pure electric vehicles, it also increases driving range, increases vehicle speed, and significantly increases energy recovery during driving.
Matching its superior power system, the vehicle adopts a full-loaded body structure to form a closed structure for the entire vehicle structure, and the strength and rigidity of the entire vehicle are increased, which satisfies the requirements of poor bus operation, severe overload, ordinary start-up and braking. The vehicle body structure also reduces the floor height, makes it easy for passengers to get in and out of the car at a low step, and increases the net height in the vehicle, which effectively increases the flow space in the vehicle, which is beneficial to the air flow in the vehicle and also reduces the passengers' ride time. The reduced space created by the narrowness of the space; the increase in the area of ​​the side windows has widened the passengers' vision. With the improvement of the city's beautification, the bus is like a mobile viewing platform in the middle of the city. It is not only a tool for people to travel, but also the value of “guides†that other modes of transport do not have.
The structure of the vehicle has been optimized to reduce the overall vehicle maintenance quality. The vehicle is more agile, smooth, comfortable and safe, coupled with its low floor design, humanized configuration, low emissions, environmental protection, and passengers. The advantages of large space not only embody the humanistic concept of "technology leadership, people-oriented" advocated by modern society, but also implement the concept of "energy saving and emission reduction". It is precisely this combination that is good at finding a balance between various factors, creating a unique R&D concept and product advantages for Shenlong Bus.
