Abstract

Since the birth of automobile, after more than 100 years of development, it has become an indispensable means of transportation in people's daily life. Electric vehicles have gone through key technological breakthroughs, prototype, prototype development, regional trial and small batch practical application, and are now close to commercial production. Compared with traditional vehicles, the most prominent advantage of electric vehicles is to achieve regenerative braking, that is, when electric vehicles brake or decelerate, the kinetic or potential energy of vehicles is stored in energy storage devices in the form of electric energy. Pure electric vehicles use power batteries as power sources, and their electric control systems are relatively simple and can basically work in high-efficiency intervals. From the perspective of battery technology, battery, as the power source of electric vehicles, has become the key to the development of electric vehicles. Based on the principle of auxiliary braking, this paper analyzes the typical regenerative braking system structure of 4WD electric vehicle and introduces the regenerative braking control strategy of 4WD electric vehicle.
