Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] A multi-factor charging method for electric vehicles considering energy information in intelligent transportation, the implementation steps are as follows:

[0027] Step 1: The electric vehicle sends a query request to the RSU within the communication range, and predicts the probability of the electric vehicle obtaining information when the electric vehicle communicates with the RSU. The simplified scene diagram of the information acquisition probability under the communication coverage of two RSUs is shown in Figure 4 shown. When the electric vehicle communicates with the first RSU, the probability that the electric vehicle obtains is P f , such as formula (1).

[0028]

[0029] When the electric vehicle leaves the first RSU and drives to the second RSU, the probability of obtaining information when the electric vehicle communicates with the second RSU i...

Abstract

The invention belongs to the field of electric vehicle charging scheduling and discloses an energy information considered electric vehicle multi-factor charging method for intelligent transportation.The method includes: step one, a vehicle sends a query request to RSU in a communication radius of the vehicle to acquire charging station state information in a traveling process; step two, after theRSU receives the query request from the electric vehicle, cached charging station state information is released; step three, after charging station selection related factors are obtained according tothe method, an optimal charging station is selected according to a multi-factor optimal charging station selection strategy; step four, whether to update appointment or not is determined according tonewly acquired information in a process of a vehicle node traveling to the selected charging station. The optimal charging station selection method based on multiple factors including travel lastingtime, energy, distance and the like is provided and has certain practical significance to relieve problems of range anxiety.

Description

technical field [0001] The invention relates to the field of electric vehicle charging scheduling, in particular to a multi-factor charging method for electric vehicles considering energy information in intelligent transportation. Background technique [0002] In recent years, due to people's growing living needs, more and more motor vehicles have appeared in the middle of the roads in various cities. They have brought convenience to human life, but also brought great challenges to the living environment of the earth. . Many large and medium-sized cities are shrouded in suffocating smog, which has brought unprecedented damage to the human body. Electric vehicles are being promoted by more and more governments and individuals as clean energy vehicles. However, because the development of battery technology cannot meet the long-term driving needs of electric vehicles, electric vehicles need to be charged multiple times during the journey. Each charge takes a certain amount of...
