  • Heat is wasted energy (known as i2r loss), and in an electric car, that matters. The induction motor is also not as efficient at low speeds as some.

    An electric motor's efficiency is measured by electrical power in / work produced. . The Tesla uses Wh/mile of energy (85kWh/ miles) The gas powered.

    Tesla made a significant change to its electric motor strategy with the of the performance and efficiency, the permanent magnet machine.

    They do indeed have slip. Toyota Motor Company News Release. Transportation Research Part D: Lighter materials in motor construction, new alternative solutions for rare-earth magnets, and optimized overall performance characteristics for different vehicle demands are all very much in the crosshairs of automotive engineers. Model S aerodynamics are so optimized that the total aerodynamic drag force experienced by the car — which is significantly larger in frontal area — is almost the same as a Roadster for a given speed.

    An electric car also battery electric car or all-electric car is a plug-in electric automobile that is propelled by one or more electric motors , using energy typically stored in rechargeable batteries.

    Since , a renaissance in electric vehicle manufacturing occurred due to advances in batteries, concerns about increasing oil prices , and the desire to reduce greenhouse gas emissions. Charging an electric car can be done at a variety of charging stations , these charging stations can be installed in both houses and public areas.

    Electric cars are a variety of electric vehicle EV. The term "electric vehicle" refers to any vehicle that uses electric motors for propulsion, while "electric car" generally refers to highway-capable automobiles powered by electricity. Low-speed electric vehicles, classified as neighborhood electric vehicles NEVs in the United States, [17] and as electric motorised quadricycles in Europe, [18] are plug-in electric-powered microcars or city cars with limitations in terms of weight, power and maximum speed that are allowed to travel on public roads and city streets up to a certain posted speed limit, which varies by country.

    While an electric car's power source is not explicitly an on-board battery, electric cars with motors powered by other energy sources are typically referred to by a different name. An electric car carrying solar panels to power it is a solar car , and an electric car powered by a gasoline generator is a form of hybrid car. Thus, an electric car that derives its power from an on-board battery pack is a form of battery electric vehicle BEV. Most often, the term "electric car" is used to refer to battery electric vehicles , but may also refer to plug-in hybrid electric vehicles PHEV.

    In , over 20 years before the Ford Model T , Thomas Parker built the first practical production electric car in London using his own specially designed high-capacity rechargeable batteries.

    In , electric cars found their first commercial use in the US. Based on the design of the Electrobat II , a fleet of twelve hansom cabs and one brougham were used in New York City as part of a project funded in part by the Electric Storage Battery Company of Philadelphia. Unlike gasoline-powered vehicles, the electric ones were less noisy, and did not require gear changes. Advances in internal combustion engines ICE in the first decade of the 20th century lessened the relative advantages of the electric car.

    Their much quicker refueling times, and cheaper production costs, made them more popular. However, a decisive moment was the introduction in of the electric starter motor which replaced other, often laborious, methods of starting the ICE, such as hand-cranking. Six electric cars held the land speed record. In the early s, the California Air Resources Board CARB began a push for more fuel-efficient, lower-emissions vehicles, with the ultimate goal being a move to zero-emissions vehicles such as electric vehicles.

    These early cars were eventually withdrawn from the U. California electric automaker Tesla Motors began development in on what would become the Tesla Roadster , which was first delivered to customers in Tesla global sales passed , units in September Many countries have set goals to ban the sales of gasoline and diesel powered vehicles in the future, notably; Norway by , China by , India by , Germany by , France by , and Britain by or As of [update] , electric cars are less expensive to run than comparable internal combustion engine vehicles due to the lower cost of repairs and energy.

    Several national and local governments have established incentives to reduce the purchasing price of electric cars and other plug-ins. When designing an electric vehicle, manufacturers may find that for low production, converting existing platforms may be cheaper as development cost is lower, however, for higher production, a dedicated platform may be preferred to optimize design, and cost.
