What is the Structural Principle of Electric Vehicles?

[DonovanRose]

Electric vehicles operate on the structural principle that they are composed of four main parts: the engine, chassis, body, and electrical equipment. These are further divided into three major modules: the onboard power source module, the main electric drive module, and auxiliary modules. The energy in an electric vehicle is primarily transmitted through flexible wiring rather than rigid couplings and drive shafts, allowing for great flexibility in the arrangement of its components. The layout of an electric vehicle's drive system varies significantly depending on the configuration, such as independent four-wheel drive systems or in-wheel motor drive systems. The type of motor used can affect the weight, size, and shape of the pure electric vehicle, as can the type of energy storage device employed, which also influences the vehicle's weight, dimensions, and form.
