New energy is also called unconventional energy. Refers to various forms of energy other than traditional energy. Refers to the energy that has just been developed or actively studied and needs to be popularized, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, nuclear fusion energy and so on.
The new energy vehicle refers to an automobile that uses unconventional vehicle fuel as the power source (or conventional vehicle fuel and new vehicle power device), integrates the advanced technology of vehicle power control and driving, and has advanced technical principles, new technologies and new structures.
Extended data
The characteristics of new energy are as follows:
1, which is rich in resources, generally has renewable characteristics and can be used by human beings forever. For example, it is estimated that the exploitable wind energy resources on land are 253 GW, but only 0.57 GW has been developed and utilized by 2003.
2, the energy density is low, and more space is needed for development and utilization;
3. It contains almost no carbon and has little impact on the environment;
4. Wide distribution, which is conducive to small-scale decentralized utilization;
5, intermittent supply, large fluctuations, which is not conducive to continuous energy supply;
6. Except hydropower, the development and utilization cost of renewable energy is higher than that of fossil energy.
The characteristics of new energy vehicles are:
1. After adopting hybrid power, the maximum power of internal combustion engine can be determined according to the average required power. The engine is relatively small and works under the best working conditions of low fuel consumption and less pollution. Because the internal combustion engine can work continuously and the battery can be charged continuously, its journey is the same as that of an ordinary car.
2, because of the battery, it is very convenient to recover kinetic energy when going downhill.
3. In busy urban areas, the internal combustion engine can be turned off and driven only by batteries to achieve "zero" emissions.
4. With the internal combustion engine, it is convenient to solve the high energy consumption problems such as air conditioning, heating and defrosting encountered by pure electric vehicles.
