Embodiment Construction

[0038] The charging path planning method for electric vehicles based on the intelligent transportation system proposed by the present invention, its system block diagram is as follows figure 1 As shown, the method includes the following steps:

[0039] (1) The electric vehicle sends the electric vehicle information to the traffic control center. The electric vehicle information includes: starting point A, destination B, initial power state E soc0 , battery capacity E B , departure time t 0 , The maximum mileage d of electric vehicles ran and KPGe per unit of electric energy travel; the traffic control center selects the shortest path between A and B according to the received electric vehicle information, and the distance of the shortest path is recorded as d ABmin , select the charging station T closest to destination B, and the shortest path distance between destination B and charging station T is denoted as d BTmin ; The traffic control center judges the electric energy ...

Abstract

The invention relates to an electromobile charging path planning method based on an intelligent transportation system, belonging to the technical field of operation and control of electric systems. The electromobile charging path planning method comprises the following steps of: firstly, a traffic control center judges whether an electromobile needs to be charged according to information of the electromobile; if necessary, an owner is prompted to charge the electromobile; the traffic control center searches all charging stations in the maximum range of the electromobile as candidate charging stations and calculates the charging probability of the electromobile in each charging station; a charging load is predicated according to the charging probability and is transmitted to an electric system scheduling center, and the electric system scheduling center calculates the allowable maximum charging power of each charging station and transmits the allowable maximum charging power to the traffic control center; and the traffic control center transmits traveling and charging total time sequence obtained according to the maximum charging power to the owner. The electromobile charging path planning method provides an optimal charging path for the owner of the electromobile and improves the traveling efficiency of the owner. In addition, the operation requirements of the electric system are sufficiently considered in the selection of the charging stations, and therefore the safe operation of the electric system is guaranteed.

Description

technical field [0001] The invention relates to a method for planning an electric vehicle charging path based on an intelligent transportation system, and belongs to the technical field of power system operation and control. Background technique [0002] The internationally accepted SAE J1772-2010 standard specifies three charging methods: "AC level 1" for slow charging, and "AC level 2" and "DC charging" for fast charging. Slow charging is mainly carried out at charging piles, and the charging time is 6 to 8 hours, which is suitable for electric vehicles that have been parked for a long time. Fast charging is mainly carried out at the charging station, and the charging time is 15 minutes to 2 hours. It is used for emergency charging of the electric vehicle on the way. The owner hopes that the charging power provided by the charging station is the maximum power that the electric vehicle can accept, so that it can be completed as soon as possible. Charge. However, EV chargi...
