What parts does a pure electric vehicle consist of?

Pure electric vehicle consists of four parts, namely: power battery, chassis, body and electrical appliances. The new energy electric vehicle consists of four parts: power battery, chassis, body and electrical appliances. As an important part of electric vehicle, power battery is divided into four main parts: battery module, battery management system, thermal management system and electromechanical system. The chassis consists of four parts: drive motor and control system, running system, steering system and braking and energy recovery system.

Pure electric vehicle refers to a vehicle powered by on-board power supply and driven by motor, which meets the requirements of road traffic and safety regulations. Because it has less impact on the environment than traditional cars, its prospect is widely optimistic, but the current technology is not mature. Battery electric vehicle (BEV) is a kind of vehicle driven by rechargeable batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries or lithium-ion batteries). Although it has a long history of 134 years, it has been used only in some specific fields and the market is small. The main reason is that all kinds of batteries generally have serious shortcomings such as high price, short life, large volume and weight, long charging time and so on.
