Electric vehicle 101.

An electric car is any vehicle that is powered by a battery that has been charged by an external electricity source. Electric cars have been in existence as long as gasoline-powered cars, but have often been more expensive than conventional gas powered cars.

Modern interest in electric vehicle technology started in the 1970s as gas prices increased, leading Congress to pass the Electric and Hybrid Vehicle Research, Development, and Demonstration Act in 1976. In the 1990s, concerns about transportation emissions led to manufacturers modifying models for electric charging as well as the development of GM’s EV1 electric vehicle. However, high costs prevented these vehicles from becoming commercially viable.

Today, concerns about rising greenhouse gas emissions and a desire to save money at the gas pump have led more manufacturers to focus on fuel efficiency and electric vehicle technology. Since the release of the Toyota Prius in the early 2000s, companies such as Tesla, Chevrolet, and Nissan have all released cars with electric vehicle technology.

There are several different types of EVs that you’ll see on the road today: BEVs, PHEVs, and HEVs. Read on to learn more about these different types.
