An electric car is car that is driven by one or more electric motor, using electrical energy stored in batteries or another energy storage device. The idea of electric cars is not new; people have been using them for decades now. Earlier, the idea of electric cars was not popular as they were expensive to buy and maintain. Also the technology for large capacity power supply didn’t exist. But today, with the increasing global warming and rising petroleum prices, people are now valuing the concept of electric vehicles.
