What are the differences between traditional cars and pure electric vehicles?
1 Answers
Traditional cars and pure electric vehicles differ in the following aspects: 1. Structure: (1) Pure electric vehicles eliminate the traditional mechanical transmission system layout and add a power battery pack and electronic control equipment, which makes their deformation posture and mechanical characteristics in collisions different from those of traditional cars; (2) The stiffness of the lower body of electric vehicles in the battery layout area is relatively low, and due to factors such as human-machine interface and battery space, it cannot be optimized. To achieve a level comparable to traditional cars, reinforcement is needed at the front shock absorber and rear suspension spring areas; (3) Due to the current limitations in energy storage and range (time factor) and the weight of the battery pack reaching several hundred kilograms (weight factor), the demand for lightweight body design is stronger in electric vehicles than in traditional cars. 2. Environmental protection: (1) New energy vehicles are quieter than traditional cars because the main noise source in fuel-powered vehicles is the combustion engine. Therefore, replacing fuel-powered cars with electric vehicles is a primary method to reduce urban noise pollution; (2) New energy vehicles are environmentally friendly, unlike traditional cars that emit a large amount of carbon monoxide, carbon dioxide, hydrocarbons, and other exhaust gases, which can severely impact urban road environments and reduce air quality.
