Advantages and disadvantages of hybrid cars

The advantages and disadvantages of hybrid vehicles are as follows:

I. Advantages of hybrid vehicles

1. Hybrid models can be refueled at gas stations just as traditional fuel vehicles can be, and the government and corporations need not spend money on building charging stations to promote hybrid models.

2. Hybrids have excellent fuel economy and a very smooth ride, moving seamlessly between fuel and pure electric modes.

3. Hybrid models have better power than purely combustion-engine vehicles of the same displacement, and the electric motor can effectively make up for the internal combustion engine's lack of low-speed torque power during startup acceleration.

4. Because hybrids rely on electric motors to drive them at the start, the NVH inside the car is better.

Two, the shortcomings of hybrid vehicles

1, the overall price of hybrid models is high, after all, the cost of two sets of electric motor and combustion engine power system is much higher than the cost of a set of power system.

2, high-speed driving as well as driving at a constant speed is not fuel-efficient, hybrid fuel consumption advantages rely mainly on potential energy accumulation power energy saving, the more frequent braking and deceleration, or frequent starting and stopping will be relatively more energy-efficient. If you are traveling at a constant speed for a long time, the energy saving effect will be reduced accordingly.

Hybrid Electric Vehicle Working Principle

At the beginning of the vehicle driving, the battery is in a state of full power, its energy output can meet the requirements of the vehicle, the auxiliary power system does not need to work. When the battery power is lower than 60%, the auxiliary power system starts: when the vehicle energy demand is large, the auxiliary power system and the battery pack provide energy for the drive system at the same time.

When the vehicle's energy demand is low, the auxiliary power system provides energy for the drive system and at the same time charges the battery pack. Thanks to the battery pack, the engine operates at a relatively stable operating condition, resulting in improved emissions.
