What are the advantages and disadvantages of hybrid vehicles?

1, the power of engine and motor can be complementary, and the motor can be used for low-speed driving.

2. The miniaturization of battery pack makes the cost and weight lower than that of electric vehicle.

3. There is no need for an external charging system, and the problems of driving range and infrastructure can be solved with one charge.

4. The internal combustion engine mainly works near the best working point, with full combustion and clean exhaust gas; No idle start (idle stop).

5. Compared with the traditional car, the internal combustion engine always works in the best working condition, and the fuel consumption is very low.

Second, shortcomings.

1, the cost of hybrid cars is high.

2. There are fewer models to choose from.

3, the maintenance cost is high, especially the battery, once it is damaged after the warranty period, the maintenance price is expensive.

4. If there are more batteries, the weight of the car will increase, which will affect the braking performance.

5, the battery will increase security risks, such as impact combustion.
