What does an extended-range electric vehicle mean?
1 Answers
An extended-range electric vehicle is directly driven by an electric motor, with the engine not participating in the drive and no mechanical devices such as clutches or transmissions. When the battery power is insufficient, the engine is used to generate electricity to charge the battery, operating within the optimal speed range, and the battery then provides energy to the motor that directly drives the vehicle. Extension: Advantages of extended-range electric vehicles: 1. Can operate in pure electric mode, requiring a small battery capacity, low cost, and no risk of running out of power. 2. Can operate in plug-in hybrid mode, further improving fuel efficiency on top of hybrid technology. 3. Small battery charging power, eliminating the need for large charging infrastructure. 4. Battery charging and discharging can be shallow, which is beneficial for battery lifespan. 5. Features external charging methods, allowing for charging during low-cost off-peak hours. 6. Simple structure with direct motor drive, making it easy to maintain and industrialize. 7. Energy-saving: The engine always operates at optimal conditions, with high efficiency and low emissions. 8. Emission reduction: High comprehensive fuel-saving rate, with existing technology capable of saving over 50% on fuel.
