These batteries are usually composed of nickel- iron, nickel-zinc, zinc-chloride, and lead acid. One challenge that designers face is in the design of the electric car and its weight. The battery and electric propulsion system consist of 40% of the weight of the car, whereas in a gas-powered vehicle, the engine, coolant system, and other exclusive powering devices are only about 25% of weight of the car. The electric car has two sources of power, one electric and the other an internal combustion engine. The electrical power is consumed for stop-and-start driving at low speeds, whereas the gasoline propulsion is mainly used for highway speeds and mileage. The electric motor preserves gasoline and lessens pollution, and the gas-powered component makes undesirable recharging stops less …show more content…
Audi, Porsche, and Mercedes – Benz are spending greatly in battery – electric cars as opposition for the Tesla Model S, which costs anywhere between $70,000 and $105,000. However, as more electric cars are manufactured, prices are more likely to drop. In about 10 years, the price of an electric vehicle will be approximately the same price as the price a similar size gasoline vehicle. The price of batteries are also decreasing, and the price of motors and controllers and all the unique components used to manufacture electric vehicles are decreasing considerably, which will eventually cause the price of the electric car to also decrease. The want for electric vehicles is increasing around the world. In 2014, there were more than 320,000 new electric vehicles registered in 2014. The United States specifically saw a great increase in the demand for electric cars. The growth rate in the United States increased about 128% from 2012 to 2014. The global market saw a growth of about 76% between 2012 and 2014. The U.S. Energy Department is requesting the nation’s electric utility industry to help with reinforcing the growth in the electric vehicle
