The invention provides a charging pile navigation method and system, and belongs to the field of vehicles. The charging pile navigation method comprises the following steps of: when the battery capacity of a vehicle is detected to be lower than a threshold value, enabling the navigation function of a navigation platform, and sending the information of distance per charge which can be maintained bythe battery capacity to the navigation platform; obtaining the information of charging piles in the driving range of the vehicle, which is calculated by the navigation platform according to the information of distance per charge; obtaining the status information and location information of applicable charging piles in the driving range of the vehicle, and sending the status information and location information to a vehicle-mounted information entertainment main machine; displaying the status information and the position information, and receiving the input first navigation information of a first target charging pile or first reservation information; transmitting the first navigation information to the navigation platform so as to obtain a corresponding navigation route, or transmitting the first reservation information to a charging pile management platform so as to reserve the first target charging pile. The invention also provides a corresponding charging pile navigation system. Thecharging pile navigation method and system can be used for finding the charging pipes meeting the requirements rapidly and accurately.
