It is unclear who the first inventor was, but Ányos Jedlik of Hungary built a small model of a working electric car in 1828. In the 1830's Robert Anderson of Scotland, Professor Stratingh of Holland and Thomas Davenport, a blacksmith from Vermont all built electric vehicles. Davenport is said to be the inventor of the DC electric motor. In 1865, Gaston Plante of France made a better battery. In 1886, the inventor Frank Sprague of Connecticut made important changes to the electric motor.
