Stagnation period
1920 - 1990: With the development of Texas oil and the improvement of internal combustion engine technology, electric vehicles gradually lost their advantage after 1920. The automotive market is gradually being replaced by internal combustion engine-driven vehicles. Only a small number of cities retain very few trams and trolleybuses, as well as very limited battery cars (using lead-acid battery packs, used in golf courses, forklifts, etc.).
The development of electric vehicles has been stagnant for more than half a century. As oil resources flow to the market, people almost forget the existence of electric vehicles. Relatively used in electric vehicles: electric drive, battery materials, power battery packs, battery management, etc. can not be developed or used.
Recovery period
1990 - to date: the declining oil resources, the serious pollution of the atmospheric environment, and the electric vehicles that people are paying attention to. The use of electric vehicles before 1990 was mainly dominated by the private sector. For example, the NGO academic organization established in 1969: World Electric Vehicle Association. Every year and a half, the World Electric Vehicle Association holds professional electric vehicle academic conferences and exhibitions Electric Vehicle Symposium and Exposition (EVS) in different countries and regions around the world. Since the 1990s, major automobile manufacturers have begun to pay attention to the future development of electric vehicles and have begun to invest capital and technology in the field of electric vehicles. At the Los Angeles Auto Show in January 1990, GM's president introduced the Impact electric car to the world. In 1992, Ford used Ecostar for calcium and sulfur batteries, Toyota used RAV4LEV for nickel-hydrogen batteries in 1996, Clio of Renault in France in 1996, and Toyota's Prius hybrid car in 1997. In 1997, Nissan was the world's first car. The electric car Prairie Joy EV with lithium-ion battery, Honda released and sold Hybrid Insight in 1999.
