Problems solved by technology
[0004] At present, there is a reservation mechanism for electric vehicles, but when the current reservation plan is technically implemented, it is generally to initiate a reservation command, then charge in sequence, and deduct fees after charging, etc., without considering how to optimize the reservation, how to achieve it in the shortest time To achieve fast charging, when there is a breach of contract, it will lead to inaccurate display information, affect the overall charging efficiency, and cannot eliminate the impact of breach of contract in time. In short, the current charging method cannot achieve efficient and fast charging technically.

Embodiment 1
[0046] This embodiment discloses a reservation-default charging method for electric vehicles. In an implementation example, reservation charging can be realized based on a cloud platform. Specifically, the cloud platform is composed of an information layer, a computing layer, and a decision-making layer. The reservation based on the cloud platform The system can obtain information covering all electric vehicles and fast charging stations in the area and give charging appointment and scheduling suggestions after calculation and processing. The principle of appointment charging is first come first served. During the operation of the appointment system, the cloud platform always maintains smooth information communication with the fast charging stations under its jurisdiction, and updates the real-time electricity price and pile position status of each charging station in real time. As an intelligent system that collaboratively considers the grid-road network, the cloud platform r...

The invention provides an electric vehicle reservation-default charging method and system. The method comprises the steps: initiating an appointment charging request, and selecting target electric quantity; after a charging reservation request is received, according to the real-time position of an electric vehicle, reading remaining electric quantity and battery health state information of the vehicle, providing a reservable charging station scheme, solving an optimal reservable charging station which comprises the distance, the arrival time and the in-station waiting time, and listing corresponding detailed information for selection; after a charging station scheme is determined, enabling the charging station to judge whether the reservation is accepted or not according to in-station energy storage, pile position use and reservation conditions; and performing two-way selection and mutual confirmation between a charging request initiator and the charging station so as to finish the reservation. According to the technical scheme, the charging efficiency can be improved.
Description
technical field [0001] The disclosure belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle reservation-default charging method and system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Under the background of the depletion of fossil energy and the increasing pressure of global warming, electric vehicles (electric vehicles, EVs) are being used more and more due to their outstanding advantages such as zero exhaust emissions, low maintenance costs, and high controllability. Issues such as the interaction between EVs and the power grid that have emerged also need to be resolved urgently. [0004] At present, there is a reservation mechanism for electric vehicles, but when the current reservation plan is technically implemented, it is generally to initiate a reservation command, then ...
