What is a Range-Extended Electric Vehicle?
2 Answers
Range-extended electric vehicles (REEVs) refer to electric vehicles that, based on pure electric vehicles, add an internal combustion engine to charge the power battery or directly drive the motor to extend the driving range, thereby overcoming the short driving range of pure electric vehicles. Additional information: 1. Advantages of range-extended electric vehicles: The advantages of range-extended electric vehicles include eligibility for green license plates, good power performance at medium and low speeds, relatively lower fuel consumption compared to traditional fuel vehicles, and no range anxiety. 2. Disadvantages of range-extended electric vehicles: As for the disadvantages, there is an inequivalence between charging efficiency and power output requirements. Currently, the maximum speed of high-voltage DC fast charging is 80 kWh, while the power generation efficiency of the range extender usually does not exceed 40 kWh, with most staying within 30 kWh. However, the energy required during initial acceleration often exceeds 30 kWh, and even 80 kWh may not be sufficient during high-speed overtaking.
When I first bought an extended-range electric vehicle, I was also puzzled by what the term meant. After driving it for half a year, I finally figured it out. Simply put, it's an electric car with a small fuel-powered generator added. When the battery is almost out of power, the engine automatically starts to generate electricity and recharge. Normally, it drives like a pure electric car, super quiet, and for long trips, you just need to refuel without queuing for charging. My car can run 1,200 kilometers on a full charge and full tank of gas, and pure electric power is enough for daily commuting in the city. Recently, with rising fuel prices, my colleagues spend 2,000 yuan a month on gas for their fuel cars, while I only spend 500 yuan on charging and a small amount of fuel. This car is especially suitable for cities where charging stations are not yet widespread, completely eliminating the worry of queuing at charging stations.
