1, Low energy conversion efficiency: extended range new energy vehicles at work will first be powered by the engine to the battery, and then the battery to the motor power supply, need to go through multiple energy conversion to complete the vehicle drive, and during this period there will inevitably be energy loss, the energy conversion efficiency of the model is not as good as other direct drive models.
2, The model choice is less: the current model on the domestic market is relatively small.
3, Does not count fuel economy: the extended-range model is not only equipped with a large-volume battery pack, the car is also equipped with an extended-range system composed of the engine, fuel tank and other components, so the extended-range car is generally heavier than other models, and the fuel consumption performance of the vehicle is relatively worse.
