The very main difference between an electric vehicle and a gasoline driven car is its power plantAn electric car uses an electric motor to generate torque to move the vehicle while a conventional car uses an internal combustion engineAn electric motor does use gasoline for power, instead it uses electric currentTo supply the power to the motor, a series of batteries are usedAn electric vehicle (EV) would need up to 15 to 20 units of batteryOn a full charge, the EV would able to cover approximately 150 milesUnfortunately, after some time, the battery would lose its storing capability therefore reducing the EV mileageWhy does a battery efficiency drops after some time? This article will provide some information on the subject.

Most batteries are made up of plates inside, that when left in an undercharged state becomes sulfatedThat means that they develop a layer of sulfate crystals on the surface of the platesWhen the plates are covered by the sulfate, there are less surface contact between the metal and the distilled waterThis will restrict the flow of electron in the batteryWhen the plates are fully covered by crystallized sulfate, there is no electron movement at all therefore killing the battery.

Apart from the electric motor, the battery bank is one of the biggest expenses in a Do It Yourself (DIY) electric car conversion projectThere are ways where you can recondition a dead battery for EVThe process can be dangerous and would be a better idea to outsource it to a professional.
