Both range extender hybrid and plug-in hybrid have their own advantages. The following is a comparative analysis of the two:
1. Power system structure and driving mode:
Range extender hybrid: mainly composed of a range extender, generator, battery, and drive motor, with two modes: pure electric and range extender. The engine does not directly drive the vehicle, but charges the battery, which then drives the motor.
Plug in hybrid: Combining the engine and electric motor, the power system structure is relatively complex. When the battery is depleted, the engine can directly drive the vehicle, with more flexible and variable driving modes that can automatically switch according to road conditions and driving needs.
2. Performance and battery life:
Extended range hybrid: In pure electric mode, the range is longer, but fuel consumption may be higher at high speeds. Because it is mainly driven by an electric motor and there is no gearbox, the speed can only be increased by increasing the motor speed, which may increase energy consumption.
Plug in hybrid: Although the range in pure electric mode is not as good as that in extended range, the engine has high thermal efficiency and low overall fuel consumption. Plug in hybrid can automatically switch driving modes according to actual conditions, providing stronger power and better fuel economy.
3. Purchase and usage costs:
Extended range hybrid: The purchase cost is relatively high, with a price range of over 300000 yuan. But in daily use, fuel consumption is lower, especially in urban working conditions where it performs better. Post maintenance mainly focuses on the battery and motor transmission system, and most electric vehicle manufacturers have established convenient battery replacement and repair networks in major cities, making maintenance more convenient.
Plug in hybrid: The purchase cost is relatively affordable, with a price range of 150000 to 300000 yuan. In terms of usage cost, plug-in hybrid may have more advantages in high-speed operating conditions. However, the construction of plug-in hybrid systems is relatively complex, and if the system is damaged, the later maintenance costs may be higher.
Both range extender hybrid and plug-in hybrid have their own advantages. If pure electric range and daily fuel consumption cost are more important, range extender hybrid may be more suitable; If pursuing a wider range of usage scenarios, stronger power, and better fuel economy, plug-in hybrid has more advantages. The final choice still needs to be determined based on individual needs and usage scenarios.
