In order to welcome the Youth Olympic Games, the Shenhua Bus New Energy Bus held an exhibition with the theme of “Green Youth Olympics and Green Dynamics†in Nanjing. It showed the 12-meter pure electric bus and the 12-meter hybrid of Shenwo. Power buses and other new energy products.
Pure electric buses have obvious advantages over traditional buses:
Non-pollution, low noise: Electric vehicles have no exhaust gas produced during the operation of an internal-combustion engine, and do not produce exhaust pollution. They are very beneficial to environmental protection and air cleanliness, and are almost “zero pollutionâ€. It is well-known that pollutants such as CO, HC and NOx, particulates, odors, etc., in the exhaust gas of internal combustion engines form acid rain mists and photochemical smog. Electric cars have no noise from internal combustion engines, and motor noise is also smaller than internal combustion engines. Noise is also harmful to the human auditory, nervous, cardiovascular, digestive, endocrine and immune systems.
The structure is simple and maintenance is convenient: the electric vehicle has a simpler structure than the internal combustion engine, and the operation and transmission components are small, and the maintenance workload is small. When using AC induction motor, the motor does not need maintenance, and more importantly, the electric vehicle is easy to operate;
High energy conversion efficiency: At the same time, braking and downhill energy can be recovered, and energy utilization efficiency can be improved;
The most worrying aspect of an electric bus is how many kilometers of electric energy can it take to recharge it? Wei Wei said that according to their tests, pure electric buses can carry passengers between 100 and 120 kilometers when fully charged. However, during the interview, the reporter learned that the current mileage of a bus is about 250 kilometers, and a pure electric bus can only carry passengers between 100 and 120 kilometers at a time. From the data point of view, it is impossible to satisfy the one-day driving mileage of a bus after it is filled with electricity. How can this problem be solved?
At the scene, the reporter saw a pure electric city bus. If light looks like a car, it's exactly the same as a regular car. "It's the most important core is hidden in the bottom of the carriage." Wei Wei, deputy chief engineer of Shanghai Shenwo Bus Co., Ltd. introduced that the pure electric bus replaced a fuel tank with a new control system compared to the traditional diesel bus. The function of the engine and the operating system, and 9 groups of batteries constitute a large energy, so as to ensure the normal operation of electric buses.
At the same time, Yu Weifeng also told reporters that he could use the time of the evening's low electricity to charge the vehicle. Each electric vehicle has a charging socket, and it can be directly connected to the power supply. The entire vehicle is charged for 3 hours and the vehicle is fully charged.
Every winter, due to the relatively low temperatures, buses that have already appeared early need to be warmed up in advance. Sometimes, because the temperature is too low, even the phenomenon of no fire can occur. In contrast, pure electric buses will have the same situation? "Pure electric buses will not be affected by temperature." Wei-Feng Feng told reporters that from the current data point of view, in the range of minus 15 °C to 50 °C above zero are in line with the required temperature, will not let pure electric buses appear Bad phenomenon.
Not only does the outside world have little effect on it, pure electric buses also have a series of advantages. For example, the battery life of the vehicle can reach 500,000 kilometers, the economic speed is 70km/h, and the maximum climbing grade is not less than 20 degrees, and energy recovery is achieved during taxiing. Compared with traditional fuel vehicles, the energy-saving advantages of pure electric buses are obvious. Their core values ​​are: the substitution of traditional energy sources and the environmental effects of zero emissions.
