Electric vehicle navigation method and system based on power guidance of energy-storage charging pile

摘要

An electric vehicle navigation method based on power guidance of an energy-storage charging pile. An electric vehicle selects, according to location information of charging piles and real-time stored power information of energy storage modules of the charging piles, a charging pile nearby that can meet own charging power demand and moves thereto for charging. The system using the method comprises a charging pile provided with a control module, a positioning module, an energy storage module, and a communication module; the electric vehicle is provided with a communication unit; the control module separately acquires the location information of the charging pile and real-time stored power information, and sends the information to the communication unit of the electric vehicle by means of the communication module. The navigation method and system can reasonably guide the electric vehicle to charge according to the distribution of charging piles and the stored power, and can dynamically plan a charging scheme for the electric vehicle, thereby preventing the electric vehicle from stop on the way due to no power and long-term inefficient waiting for charging, so that the stored power of the charging pile can be reasonably distributed and used, and energy idleness and waste are avoided.
