These data can only be achieved under specific conditions and do not have universal significance. They are all provided by car companies to the government. CUHK once had an electric bus with a claimed driving range of 500 kilometers. It even conducted an experiment and drove it from Beijing to Tangshan and back without charging. Many experts, academicians and reporters were invited to witness the bus. The bus did drive a round trip, but after You can tell by looking inside the car. They removed all the seats and installed batteries. How do you think of promoting such a car? The current bottleneck is mainly in batteries, which are too expensive, require high maintenance costs, and have immature supporting facilities. In addition, there are many technical solutions for electric vehicles that are still in the demonstration stage, especially in terms of safety, reliability and electromagnetic compatibility, which are much higher than ordinary cars. This is equivalent to a high-voltage distribution box running on the street, which is slightly worse. Flaws, that's no joke.
