新能源汽车以其低油耗、低排放以及能量来源形式多样等优点，已成为目前汽车发展的重要方向。目前，主流的汽车制造商均已进行新能源汽车的研发和制造。虽然纯电动汽车具有低噪声、零排放、零污染的优点，但是由于动力电池组的技术短板，其存在着单次充电续航里程短、车辆制造成本高等缺点。常规混合动力汽车虽可以达到节能减排的目的，但仍主要通过燃油来提供动力，能量转换效率低且排放效果较差。With the advantages of low fuel consumption, low emission and various forms of energy sources, new energy vehicles have become an important direction of current automobile development. At present, mainstream automobile manufacturers have all carried out research and development and manufacturing of new energy vehicles. Although pure electric vehicles have the advantages of low noise, zero emissions, and zero pollution, due to the technical shortcomings of the power battery pack, they have disadvantages such as short mileage on a single charge and high vehicle manufacturing costs. Although conventional hybrid vehicles can achieve the purpose of energy saving and emission reduction, they are still mainly powered by fuel, with low energy conversion efficiency and poor emission effect.

增程式电动汽车综合了纯电动汽车和混合动力汽车的优点，其既可以通过纯电动模式行驶，满足人们日常的通勤需求。也可以通过增程模式行驶，摆脱动力电池容量和充电条件的限制，延长了续驶里程，同时通过控制电机将发动机调节在最佳经济区域，优化了能量经济性和排放性。Extended-range electric vehicles combine the advantages of pure electric vehicles and hybrid vehicles, which can be driven in pure electric mode to meet people's daily commuting needs.
