What's the difference between a traditional car and a pure electric car?

The difference between traditional cars and pure electric cars is as follows: 1. Structurally: (1) The pure electric vehicle cancels the traditional mechanical transmission system layout, and adds a power battery pack and electronic control equipment, so that its deformation posture and mechanical characteristics are different from those of traditional vehicles during collision; (2) The rigidity of the lower body of the electric vehicle in the battery layout area is low, and it cannot be optimized due to human-machine and battery space. In order to reach the level of traditional cars, it is necessary to strengthen the front shock absorber and the rear shock absorber spring; (3) Due to the low energy storage and endurance of pure electric vehicles at present (due to time) and the weight of battery pack reaching hundreds of kilograms (due to weight), the demand for lightweight body design is stronger than that of traditional vehicles. 2. Environmental protection: (1) New energy vehicles are quieter than traditional vehicles because the main noise of fuel vehicles comes from over-oiled engines, so replacing fuel vehicles with electric vehicles is a major way to reduce urban noise pollution; (2) New energy vehicles are environmentally friendly, unlike traditional vehicles, which will emit a lot of carbon monoxide, carbon dioxide, hydrocarbons and other waste gases, which will seriously affect the urban road environment and reduce air quality.
