This document discusses electric vehicle mechanisms. It begins by defining electric vehicles and noting they use electric motors powered by batteries or solar panels rather than gasoline. It then covers the history of electric vehicles dating back to 1827 and discusses how they gained more popularity in the early 1900s but declined due to battery limitations. The main sections summarize the working of electric vehicle components like induction motors, inverters, and lithium-ion batteries. It compares electric vehicles favorably to internal combustion engines in aspects like direct rotational motion, uniform power output, and higher power-to-weight ratios. The conclusion discusses the need to improve batteries and charging to make electric vehicles more viable and reduce pollution from gasoline vehicles.
