The invention provides a novel electrocar. The novel electrocar comprises a three-speed motor and a three-gear relay. A coil of the motor comprises three gears, namely a high-speed gear, a middle-speed gear and a low-speed gear. The three-gear relay comprises two independent relays integrated inside a shell, one of the two relays is provided with a common end and the other is not provided with the common end, and a normally closed contact of the former relay is connected with a movable contact of the other relay. By adopting the three-speed motor and the three-gear relay to control the speed of the electrocar, the rotative speed difference among the three gears is small, and the shifting effect is stable and comfortable. Due to the fact the three-gear relay adopts two existing relays which are integrated inside the shell, one common end is saved, and the wire arrangement is well-ordered and well-organized. Compared with the two independent relays, the space is saved, and the wiring is convenient during the utilization.
