New energy vehicles include blade electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy vehicles, etc.
Hybrid Electric Vehicle
Hybrid Electric Vehicle means consists of two or more single drive trains that can operate simultaneously, the driving power of the vehicle is provided by a single drive system alone or multiple drive systems based on the actual vehicle driving state. due to different components, layout and control strategies, there are many forms of hybrid cars.
Advantage
1. After the use of hybrid power, the maximum power of the internal combustion engine can be determined according to the average power required, relatively small engine(downsize）, at this time, it is working under the optimal conditions of low fuel consumption and low pollution. because the internal combustion engine can work continuously, the battery can be continuously charged, so its itinerary is the same as a regular car.
2. Because of the battery, can easily recover kinetic energy when downhill.
3. In the bustling downtown, the Internal combustion engine can be shut down, individually driven by battery, achieving “zero” emissions.
4. With the internal combustion engine, it is very easy to solve the problems encountered by pure electric vehicles such as air-conditioning, heating, and defrosting, which consume large amounts of energy.
5. Can use existing gas stations for refueling, no need to invest again.
6. Keeps the battery in good working condition, no overcharge or over-discharge, prolong its service life and reduce costs.
7. Vehicle due to multiple power sources can work simultaneously, excellent vehicle dynamics.
Disadvantage
Relatively complex system structure; the fuel-saving effect of long-distance high-speed driving is not obvious.
