1.Core differences: technical principles determine "character"

Pure electric vehicles: rely on battery-driven to obtain electricity from charging piles or home sockets, just like a "mobile terminal carrying a power bank". The advantage is fast power response, quiet driving, and zero exhaust emissions; the disadvantage is that the endurance is limited by the battery capacity, and the endurance is easy to be discounted when driving at low temperatures and high speeds in winter.

Hybrid car (HEV/PHEV): Combined with a fuel engine and an electric motor, the engine can directly drive the wheels or generate electricity.

•HEV (oil-electric hybrid): cannot be charged externally, relying on brake recovery and engine excess power charging, suitable for urban congested road conditions, fuel-saving but not pure electric long-lasting.

•PHEV (plug-in hybrid): rechargeable, pure electric range generally 50-200 kilometers, long-distance switching fuel mode, taking into account the characteristics of pure electric economy and fuel-powered vehicles without anxiety.

Extended range electric vehicles: the engine does not directly drive the wheels, but only the power supply is used, similar to the "power bank with its own generator". Pure electric range is generally more than 200 kilometers. After there is no power, it relies on the engine to generate electricity to avoid mileage anxiety, but the engine efficiency is low under high-speed working conditions.

2.Usage scenarios: commuting, long-distance and charging conditions are the key

• Daily commuting ≤50 kilometers, fixed charging pile: pure electric vehicles are the best choice. The charging cost of Gudian at night is low, which is suitable for urban walking. For example, BYD Dolphin and Wuling Bingguo have a range of more than 400 kilometers, covering a week's commuting.

• Commuting + medium and short-distance self-driving tour:plug-in hybrid (PHEV) more flexible. For example, BYD Tang DM-i pure electric range of 112 kilometers meets daily needs, full fuel and full battery range of more than 1,000 kilometers, and there is no pressure on weekend driving; although Honda CR-V Rui·Hybrid cannot be charged externally, the comprehensive fuel consumption is 4-5L/100km, which is suitable for users who often run in the suburbs.

• Long-distance demand is high, and charging is inconvenient: it is safer to choose extended range vehicles or oil-electric hybrids. The Lixiang L7 pure electric range is 210 kilometers, and the comprehensive range after the intervention of the range extender is more than 1,300 kilometers; the fuel consumption of the M5 range-extended version is about 7L, which is slightly saving than that of fuel vehicles of the same class, and is suitable for users who often travel across cities.

3.Special needs: these factors should also be considered.

• Charging convenience: There is no charging pile in the community/company, so choose the pure electric car carefully; hybrid and extended range can be refueled for emergency.

• Winter car environment: In the extremely cold areas of the north, the pure electric range may be 50% off, and the hybrid and extended range are more stable.

• Driving experience preference: Pursue extreme quietness and acceleration, choose pure electric; get used to the driving feeling of fuel vehicles and choose hybrid; want to take both into account,extended range is a compromise plan.

4.Summary: There is no "best", only "most suitable"

• Pure electricity is suitable for users who are convenient to charge and travel short distances, and enjoy a low-cost and intelligent experience;

• Hybrid is suitable for families with limited budgets and occasional long distances, taking into account economy and practicality;

• Range increase is suitable for people who are sensitive to endurance anxiety and pursue pure electric driving experience.

Before buying a car, you might as well test drive different types of models, and combine your commuting distance, charging conditions and budget range to find a "green partner" that really meets your needs.
