What are new energy vehicles?
New energy vehicles refer to all other energy vehicles except those that use fossil energy such as gasoline, diesel and natural gas as engine fuel.
These include pure electric vehicles, hybrid vehicles, fuel cell vehicles and solar cars.
1. Pure electric vehicle: Pure electric vehicle is, as the name implies, a vehicle driven purely by electric energy.
It must be charged using a special charging post or a special charging place to drive.
The typical example is.
Its advantages are simple structure, less maintenance items, low cost;
The disadvantages are short battery range and battery life, temperature has a very large impact on battery capacity, and the convenience of charging is not good.
Due to the wide range of sources of electricity, there will be cleaner electricity generation in the future, so pure electric vehicles are the ultimate development trend in the future.
2. Hybrid Electric vehicles A hybrid electric vehicle is a vehicle that has at least two power sources and uses one or more of them to provide part or all of its power.
General power source using gasoline engine and motor hybrid drive, it can be in pure electric mode, pure oil mode and oil electric hybrid mode under three states.
Hybrid electric vehicles can be classified as regular hybrid electric vehicles, plug-in hybrid electric vehicles and extended-range hybrid electric vehicles.
(1) Ordinary hybrid power Ordinary hybrid vehicles are mainly driven by engines in the normal running process.
Only when the vehicle is starting or driving at low speed, it is driven by the motor. When it meets the ramp or rapid acceleration, the engine and the motor jointly drive the vehicle.
It uses excess power from the engine to recharge the battery while the car is moving, so it doesn’t need an external power source.
But its pure electric range is extremely short, usually no more than 5 kilometers.
Typical examples are hybrid models such as the Toyota Corolla.
The average hybrid is essentially a gasoline car, but it allows the gasoline engine to spend more time in the efficient range.
