However, it is obvious that this way of self-determination has obvious randomness and non-repeatability
At the same time, the charging scheduling and guidance in the existing market is basically in a blank state
This undoubtedly makes the charging process of electric vehicles extremely chaotic, and it is almost impossible to achieve the global optimum, which seriously affects the efficiency of the system.

Embodiment Construction
[0031] like figure 1 Shown is a schematic flow chart of the method of the present invention: the time-sensitivity-based electric vehicle charging guidance method provided by the present invention includes the following steps:
[0032] S1. Obtain the attributes and current status of charging piles in the area to be analyzed;
[0033] S2. Construct the calculation model of the user's overall charging time consumption; specifically, the following steps are used to construct the model:
[0034] A. Use the following formula to calculate the driving time T of the i-th electric car i,drive :
[0035]
[0036] where S i,d is the driving distance of the i-th electric vehicle; K i,drive is the congestion coefficient of the i-th electric vehicle, defined as the ratio of the length of the lane section during the charging process of the i-th electric vehicle to the traffic flow at this time; V i,car is the driving speed of the i-th electric vehicle;
[0037] B. Use the following f...

The invention discloses a time-sensitivity-based electric vehicle charging guidance method, which includes acquiring the properties and current status of charging piles in the area to be analyzed; constructing a user's overall charging time-consuming calculation model; solving the calculation model and calculating the user's charging pile Selection effect; charging guidance for vehicles in the area to be analyzed. The time-sensitivity-based electric vehicle charging guidance method provided by the present invention realizes the guidance optimization of the overall electric vehicle charging pile in the area through accurate modeling and calculation, and has high reliability, good practicability, and can realize global Charging schedule.
Description
technical field [0001] The invention belongs to the field of electrical automation, and in particular relates to a charging guidance method for electric vehicles based on time sensitivity. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source for people's production and life. With the increasing environmental problems, electric vehicles are becoming more and more popular. With the popularization of electric vehicles, the charging problem of electric vehicles is becoming more and more important. [0003] At present, when an electric vehicle owner needs to go to a charging pile for charging, the owner often obtains the status of the current nearby charging pile through the existing app, makes a decision by himself, and drives to the corresponding charging pile for charging. However, it is obvious that this way of self-determination has ...
