What Does Extended-Range New Energy Vehicle Mean?
2 Answers
Extended-range new energy vehicles refer to cars that are based on pure electric vehicles but have an added gasoline engine. The primary function of the gasoline engine is to either charge the vehicle's battery or directly power the vehicle's motor to extend the driving range. The powertrain of an extended-range electric vehicle mainly consists of four components: the power battery system, the power drive system, the range extender, and the vehicle control system. The power battery system provides energy for the motor drive system while also supplying reverse current to start the range extender engine. Typically, extended-range electric vehicles have power batteries with sufficient stored energy, so the motor is primarily powered by the battery. Within a certain driving time frame, the vehicle's driving characteristics are identical to those of a pure electric vehicle.
I've driven an extended-range electric vehicle (EREV), which is primarily an electric car but equipped with a small engine acting as a generator. This means it uses the battery to power the electric motor for driving, and when the battery runs low, the engine starts to generate electricity to recharge the battery, without directly driving the wheels. This extends the range, making long trips worry-free, like easily covering 300 kilometers back to my hometown without charging. It perfectly solves the range anxiety of pure electric vehicles, offering cost-effective and eco-friendly city driving with electricity, and stress-free highway driving with fuel. For example, driving the Li ONE, my daily commute is low-cost using electricity, and weekend trips are smooth with fuel. This type of vehicle combines the advantages of electric and fuel-powered cars, offering high flexibility in real-world driving. With low charging frequency, it's especially suitable for frequent travelers, eliminating the hassle of finding charging stations while maintaining efficient travel.
