What are the range-extended electric vehicles?
1 Answers
Range-extended electric vehicles include Li ONE, Buick Velite 5, Chevrolet Volt, GAC Trumpchi GA5, and BMW i3, among others. The positioning of range-extended electric vehicles is relatively ambiguous and can be considered as a transitional model between pure electric vehicles and hybrid vehicles. The powertrain of a range-extended electric vehicle mainly consists of a range extender, motor, battery, and vehicle controller. Compared to pure electric vehicles, the main difference is the addition of a range extender. The range extender is essentially an engine. In most cases, the vehicle operates in pure electric mode. When the battery energy is insufficient to provide power, the range extender kicks in. Here, the engine does not directly drive the motor but instead drives a generator to produce electricity, which is then transmitted to the motor. The motor then converts this electrical energy into mechanical energy to drive the vehicle.
