What are the advantages of a hybrid car with gasoline and electricity? What are the disadvantages

Advantages of hybrid cars:

1. Compared with conventional cars, fuel consumption is very low because the internal combustion engine always works at the optimum working condition.

2. The internal combustion engine mainly works near the optimal working condition point, combustion is full, and the emission gas is cleaner; there is no idling at the start (idling stop).

3. No external charging system is required, and issues such as mileage on a single charge and infrastructure are resolved.

4. Miniaturization of the battery pack makes the cost and weight lower than that of electric vehicles.

5. Engine and motor power can be complementary; at low speeds, the vehicle can be driven by an electric motor.

Under the current technological level and application conditions, hybrid vehicles are the most promising models for industrialization and marketization among electric vehicles. Hybrid vehicles use internal combustion engines and electric motors as hybrid power sources, which have the advantages of good power, fast response and long working time of fuel engines, and the benefits of non-polluting and low-noise electric motors, achieving the best match between engines and electric motors.

Disadvantages of hybrid cars:

1. Expensive. Due to the high manufacturing cost of current battery technology, the hybrid version is expensive for the same car performance.

2. Less range. Pure use of electricity, the current technology is limited, domestic manufacturers of new energy vehicles range kilometers more difficult to break through 100KM.

3. Maintenance costs are expensive. Relative to the traditional engine, more than the battery a piece of maintenance, and the current cost is not low.

Expanded information

Development status:

The concept of hybrid technology and patent authorization of the public, the earliest in China's National Patent Office to achieve. At the end of the 1990s, the development of electric vehicle bicycle applications in China had just begun. The bottleneck in EV technology was first exposed, namely the limited energy of the battery, resulting in extremely limited power and driving range of the vehicle.

Currently, China's major automobile groups are carrying out research and development of hybrid electric vehicles, most of which are based on hybrid electric buses, and this direction of research and development is in line with China's national conditions and is conducive to the research and development of electric vehicles in China. At the same time, new energy vehicles as the main direction of future automobile development, the state has always given support and encouragement. Such as "Automobile Industry Development Policy", "Eleventh Five-Year" Automobile Industry Development Plan and other policies and documents to encourage the development of clean cars, alternative fuels and automotive fuel-efficient technologies.
