The invention relates to a method and a system for providing driving route information of an electric vehicle. The method and the system implemented for providing driving route information of an electric vehicle to a telematics terminal by a telematics server may include checking a driving pattern of a driver corresponding to the electric vehicle; checking information on a current position and a destination of the electric vehicle; calculating at least one candidate route from the current position to the destination; calculating expected power consumption corresponding to each of the at least one candidate routes based on the driving pattern, the current position, and the destination; and transmitting information on the at least one candidate route and the expected power consumption corresponding thereto to the telematics terminal.
