【正文】 as a major transportation tool and widely used in the society for local transportation improved from horse carriages. Until 1930, electric vehicle leadership was overtaken by gasoline vehicle development and was never able to reclaim the status for following reasons: Maturity of Gasoline vehicle and can be mass produced at a reasonable cost. With the mass production of Model T amp。 Gasoline vehicle took over as the leader and surpass electric vehicle both in performance and cost. Infrastructure improvement and demand of intercity travel required a longer travel distance that was never able to exploit by electric vehicle before. Lacking of charge infrastructure development, reliable electricity transmission and limited travel distance, electric vehicle no longer suited for consumer demand and lost the edge to regular gasoline vehicle. Limited or no electrical infrastructure support forced the resignatio n and abundance of earlier electric vehicle. Widely discovery of gasoline in the sate and ready availability of cheap fuel also contributed the spread of gasoline vehicle. Petrol in the 1930s provided a direct cheap source of energy for vehicle transportation. It could be carried around by container which enabled and extended the mobility of owning a vehicle. B. Midterm development (1930s1980s) Electric vehicle production and development came to a halt as personal transportation after bustion engine took over in 1935.

Government and environmentalist reintroduced tougher fuel efficient standard for the industry and ignited a board interest in electric vehicle in the period. Energy crisis in early 70s driven the US postal service placed a large order of 350 EV test fleet. It is the highest node of midterm development. However, partly due to limited performance, other governmental priorities, lack of board infrastructure support and range of corporation participation, the development quiet down quickly during this period. C. Modern Development Modern EV development was dominated by EV1 who produced by GM for fleet application. Following a program funded by Department of Energy, Ford developed EV Ranger pick up truck, Toyota provided Rav4 EV and Honda had an EV available as well during late 1990s and early 2020s. Unfortunately, this short surge of EV availability did not realized into mercial production because of a plicated issue of politics, economic, education and technology that includes vehicle production cost and safety concerns. EV1, Ranger, Rav4 and Honda EV were intended for fleet test only, almost all the vehicles has been discontinued, destroyed and recycled. Only a handful of electric vehicles were survived under
