A slice-groove type new energy vehicle consists of a power receiving slice which is automatically and intelligently controlled and a charging groove on a midline of a road, wherein the charging groove on the midline of the road does not occupy too much space on the road and not affect the traffic and the appearance of a city; and the charging groove is a large power supply unit consisting of numerous small power supply units. When the slice-groove type new energy vehicle runs at the middle of the charging groove, a charging groove tracking indicator light in a cab is automatically turned on, and the power receiving slice is automatically inserted into the charging groove for charging. When the slice-groove type new energy vehicle leaves the charging groove or changes lanes to left or right, the power receiving slice is automatically controlled to be in a storage state. The slice-groove type new energy vehicle is subjected to processes of identification, charging, billing and accumulating when passing each of the small power supply units. The time at which the slice-groove type new energy vehicle runs on the charging groove on the midline of the road is the time of charging, and crowded motor vehicles on urban roads are like an "oversized parking lot". The slice-groove type new energy vehicle makes full use of valuable resources of the urban roads and converts disadvantages into advantages; in addition, not only the working efficiency and charging effect of the slice-groove type new energy vehicle but also the economic efficiency is improved.
