How to distinguish between pure electric, hybrid, plug-in hybrid, and extended range vehicles?
1. Pure electric vehicle (BEV): completely dependent on battery and electric motor drive, without relying on fuel engines. Its advantages lie in low energy loss, diverse power sources, ability to optimize grid demand, low noise and vibration, and simple structure. Disadvantages include immature charging technology, limited battery life, battery life and cost issues, and battery pollution.
2. Hybrid Electric Vehicle (HEV): Combining a fuel engine and an electric motor, without the need for external charging. Its advantages include no range anxiety, low fuel consumption, smooth and quiet low-speed operation, and the added battery can improve handling. But the disadvantages are that the fossil fuel problem has not been fundamentally solved, the intervention of internal combustion engines may affect the smoothness of driving, limited performance potential, and complex technology.
3. Plug in hybrid electric vehicle (PHEV): capable of external charging, combined with a fuel engine and electric motor. The advantages include the use of new energy license plates, the transition from fuel vehicles to electric vehicles, superior power performance, and comfortable handling. But the disadvantage is that pure electric battery life is relatively short and requires frequent charging.
4. Extended Range Electric Vehicle (EREV): Charging the battery through a fuel engine and driving the vehicle with an electric motor. Its advantages include no range anxiety, the ability to use small capacity batteries, light weight, and low cost. But high-speed fuel consumption is high, and it cannot provide power at the same time as HEV.
5. Fuel cell vehicles (FCVs): convert chemical energy from hydrogen fuel into electrical energy, driven by an electric motor. Its advantages include no battery life and energy replenishment issues, no large capacity battery problems, low energy consumption, near zero emissions, and a wide range of hydrogen sources. But the disadvantages include low comprehensive energy conversion rate, complex technology and high cost, lack of hydrogenation infrastructure, high promotion resistance, as well as high cost and complex structure of fuel cell engines.
When choosing new energy vehicles, each type has its unique characteristics and applicable scenarios, which makes consumers face multiple considerations when choosing. Pure electric vehicles, plug-in hybrid vehicles, hybrid vehicles, extended range electric vehicles, and fuel cell vehicles each have their own advantages, and decisions need to be made based on individual needs and preferences.
