Preliminary understanding of new energy vehicles

Preliminary understanding of new energy vehicles

New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. A new energy vehicle refers to a vehicle that adopts a new power system and is completely or mainly driven by new energy. At present, there are four main types: hybrid vehicles, natural gas vehicles, pure electric vehicles and fuel vehicles.

Hybrid electric vehicle;

Hybrid electric vehicle (HEV) is a brand-new concept car, which uses internal combustion engine and motor as hybrid power source, which not only solves the problem of short battery life, but also reduces environmental pollution, and does not need an external charging system. The small battery pack greatly reduces the manufacturing cost and weight of the hybrid electric vehicle, and at the same time, the power of the engine and the motor can complement each other during driving, and the motor power can work at a lower speed. Wuling Star Hybrid Edition launched by Wuling Hong Guang is an example.

Natural gas vehicles:

Natural gas vehicles use sulfide-free and lead-free clean energy. Many countries, including China, are developing natural gas vehicles. Because the cost of natural gas is much lower than that of gasoline, and the engine uses natural gas, it can be used for passenger transportation and reduce the operating cost of vehicles. At the same time, the safety of natural gas is higher than gasoline. Xpeng Motors' G9 series is just like this.

Pure electric vehicle:

Pure electric vehicle is a kind of vehicle with electricity as energy source. Compared with other vehicles, pure electric vehicles have the least impact on the environment, but they are powered by renewable batteries. Due to technical reasons, it has some shortcomings, such as short service life, large volume and overall size, and long charging period. Tesla ModelX is the most widely used pure electric vehicle in the market.

Fuel truck:

Compared with traditional cars, the structure of fuel cell cars is different from that of conventional cars. The internal combustion engine is no longer used in traditional automobiles, and fuel cells are generally hydrogenated. Due to the high technical requirements, fuel cell vehicles are generally limited to the industrial field.
