specific Embodiment approach 1

[0025] Specific implementation mode 1. Electric vehicle charging route selection method, which includes the following steps:

[0026] Each electric vehicle equipped with wireless communication equipment is recorded as a node APa, and the communication radius ra of each node AP is set;

[0027] Configure each charging pile with a wireless communication device, and set the communication radius ra of the charging pile;

[0028] For each node APa, if it intends to initiate the communication process of finding a charging pile, the following steps are performed:

[0029] Step 1: Mark the node AP that initiates communication as the initiating node;

[0030] Step 2: The initiating node broadcasts a request data packet within its communication radius, and the request data packet includes: its own ID, a request to find a charging pile, and a minimum threshold of relay signal strength;

[0031] Step 3. Other nodes APa within the communication radius of the initiating node receive the request data p...

specific Embodiment approach 2

[0045] Embodiment 2 This embodiment is a further limitation of the electric vehicle charging route selection method described in Embodiment 1. The value of M ranges from 3 to 5.

specific Embodiment approach 3

[0046] Embodiment 3 This embodiment is a further limitation of the electric vehicle charging route selection method described in Embodiment 1. In step 13, if the user does not make a selection within the time t, the route selection is directly ended.

Abstract

The invention discloses an electric vehicle charging route selection method, which relates to the electric vehicle charging route selection technology. The electric vehicle charging route selection method aims to solve the problem of low operating efficiency of an electric vehicle due to waiting caused by the existing field-arrival-type electric vehicle charging method. According to the electric vehicle charging route selection method, intensities of routing nodes are screened during the route selection process of the electric vehicle, and the nodes not meeting intensity requirements are abandoned; the summarized nodes are screened again by a charging pile, and first M routers with the fastest speed are reserved and serve as relays, thereby achieving the reliability of communication; meanwhile, by adopting a screening mechanism of the electric vehicle charging route selection method, more nodes no longer participate in the whole communication process, thereby greatly saving spectrum resources. The electric vehicle charging route selection method achieves the effect of searching the charging pile quickly by the electric vehicle, can make a reservation for the charging process, avoids the field waiting process, and improves the operating efficiency of the electric vehicle. The electric vehicle charging route selection method is applicable to occasions in which the electric vehicle searches for the charging pile for charging.

Description

Technical field [0001] The invention relates to an electric vehicle charging route selection technology. Background technique [0002] As a new energy vehicle, electric vehicles are produced and used on a large scale. The electric vehicles are often equipped with wireless communication equipment for real-time and remote communication. [0003] Supporting electric vehicles are charging piles. Charging piles are used to charge various types of electric vehicles according to different voltage levels. The charging piles are used in sequence according to the on-site sequence or card swiping sequence. When the charging pile is fully used, the subsequent electric vehicles must be in a waiting state until the preceding electric vehicle is fully charged. With the increasing number of electric vehicles, this method will cause a lot of waiting time, resulting in lower operating efficiency of electric vehicles. Summary of the invention [0004] The invention aims to solve the problem that th...
