Other new energy automobile includes the use of super capacitors, flywheels and other high efficiency energy storage vehicles. At present in China, the new energy vehicles mainly refers to pure electric vehicles, extended range of electric vehicles, plug-in hybrid vehicles and fuel cell electric vehicles, conventional hybrid cars are divided into energy-efficient cars.
Classification of Goods
Hybrid Vehicle
Hybrid Vehicle is the type of vehicle that uses conventional fuel and is equipped with a motor / engine to improve low speed power output and fuel consumption. According to the different types of fuel, the main can be divided into two kinds of hybrid gasoline and diesel hybrid. The domestic market, the mainstream of hybrid vehicles are gasoline hybrid, while the international market, diesel hybrid models are also developing very fast.
Battery Electric Vehicle
Battery Electric Vehicle is the name of the main use of electric vehicles, most of the vehicles directly motor drive, a part of the vehicle to install the motor in the engine compartment, there are some directly to the wheels as four motor rotor, the difficulty lies in the power storage technology.
Fuel Cell Vehicles
Fuel cell vehicles refers to the hydrogen, methanol and other fuel, through the chemical reaction to generate current, rely on motor-driven vehicles. The energy of the battery is through the hydrogen and oxygen chemical, rather than through the combustion, directly into electrical energy. Fuel cell battery chemical reaction process does not produce harmful products, so the fuel cell vehicles are pollution-free vehicles, fuel cell energy conversion efficiency than the internal combustion engine to 2 to 3 times higher, so from the energy use and environmental protection, the fuel cell vehicle is An ideal vehicle.
Hydrogen Powered Car
Hydrogen powered car is a real zero-emission vehicle, the discharge is pure water, which has no pollution, zero emissions, rich reserves and other advantages, therefore, hydrogen-powered vehicles is the ideal alternative to traditional cars. Compared with the traditional power car, hydrogen-powered car costs at least 20% higher. China Changan Automobile in 2007 completed China's first highly efficient zero-emission hydrogen internal combustion engine ignition, and in 2008 Beijing auto show on the independent research and development of China's first hydrogen power concept sports car "hydrogen."
Natural gas car
Gas composition is single, high purity, can be mixed with air and combustion completely, CO and particulate emissions are low, the engine at low temperature when the start and run performance is better. The disadvantage is its poor transport performance than liquid fuel, the engine volumetric efficiency is low, the fire delay is longer and the power is reduced. This type of vehicle uses a dual fuel system, a compressed natural gas or liquefied petroleum gas system and a gasoline or diesel combustion system, which can easily transition from one system to another, mainly for urban buses.
Methanol Fuel Vehicle
A car that replaces petroleum fuels with methanol.
Aerodynamic vehicle
The use of air as an energy carrier, the use of air compressors to compress the air to more than 30MP, and then stored in the gas tank. Need to start the car when the compressed air is released to drive the starter motor. Advantages are no emissions, less maintenance, the disadvantage is the need for power, air pressure (energy output) with the mileage lengthened, high-pressure gas safety.
Flywheel energy storage car
The use of flywheel inertia energy storage, storage of non-full load when the engine capacity and the vehicle grows downhill, slow down the energy when driving to a generator power generation, and then drive or accelerate the flywheel rotation. The flywheel uses a magnetic levitation method that rotates at a high speed of 70000r / min. In the hybrid car as a supplement, the advantage is to improve energy efficiency, high light energy storage, energy and quick response, maintenance of long life, the disadvantage is the high cost of motor vehicles will be affected by the impact of flywheel gyro effect.
super capacitor car
super capacitor is a capacitor that utilizes the electric double layer principle. The opposite charge is formed at the interface between the electrolyte and the electrode under the action of the electric field generated by the charge on the two electrodes of the supercapacitor to balance the internal electric field of the electrolyte. This positive charge and negative charge are between two different phases Of the contact surface, with positive and negative charge between the very short gap in the opposite position, the charge distribution layer called double layer, so the capacitance is very large. (2010 Shanghai World Expo Park Expo line has been using this car)
