What Is An Electric Vehicle

Electric vehicle (BEV) refers to a vehicle that is powered by an on-board power source and uses an electric motor to drive its wheels, meeting various requirements of road traffic and safety regulations. Due to its relatively small impact on the environment compared to traditional cars, its prospects are widely optimistic.
Working principle: Battery - current - power regulator - electric motor - power transmission system - driving the car.
In September 2022, scientists from Harvard University developed a new type of solid-state lithium-metal battery for electric vehicles (EVs). 
In December 2022, the new generation of electric vehicles was selected as one of the "Top 10 Global Engineering Achievements of 2022"
