Description

Technical Field

[0001] The present invention relates to the field of electric vehicle charging and billing, and in particular to an ETC billing control system based on a vehicle charging pile. Background Art

[0002] With the rapid development of electric vehicles in the transportation industry in recent years, the corresponding charging piles have also developed rapidly and their number has increased rapidly. They can already be seen in many public places such as public parking lots, highway service areas and some gas stations.

[0003] Most of the existing public electric vehicle charging equipment uses card swiping or mobile phone scanning to pay for charging, and these require users to select the corresponding charging and payment methods themselves, and they need to operate again after charging is completed. This makes the charging payment operation process too cumbersome. In order to enable users to complete charging with simple operations, a new charging consumption method is needed to solve this problem.

[0004] Through the understanding of ETC related technologies, ETC is the electronic non-stop toll collection system for highways. When a vehicle passes through a highway toll station, the vehicle identification and information writing are realized through the on-board equipment, and the corresponding funds are automatically deducted from the pre-bound IC card or bank account. Based on the advantages of ETC, one car, one card and one label, if this technology is applied to the charging and payment process of electric vehicles, it can realize automatic deduction of fees after charging is completed, and the vehicle can go immediately after charging, which further improves the charging efficiency and realizes the control and management of intelligent interconnection of charging piles. It is more adaptable to the environment than card payment and mobile phone code scanning payment, and can quickly and reliably identify vehicle information in various harsh environments. Summary of the invention

[0005] In view of the shortcomings and deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an ETC charging control system based on a car charging pile.
