Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a non-stop mobile cabin charging system and a charging method for an electric vehicle. Background Art

[0002] Electric vehicles are vehicles driven by electric motors. Compared with fuel vehicles, electric vehicles have four main components, including drive motors, speed controllers, power batteries, and on-board chargers. Compared with gas stations, they have public ultra-fast charging stations. The quality of electric vehicles depends on these four components, and their value also depends on the quality of these four components. The purpose of electric vehicles is also directly related to the selection and configuration of the four components.

[0003] With the popularity of electric vehicles, the problem of charging electric vehicles is also a constant problem for users. When users finally find a public charging station, they often find that the public charging pile is broken or cannot be used directly, which further deepens the user's "range anxiety"; especially in winter when the temperature drops, the driving distance of electric vehicles is greatly shortened, and the charging piles are still very tight in a short period of time, and need to be charged and rescued at any time.

[0004] At present, there are charging rescue schemes for prohibited vehicles, for example, a "mobile charging system and method for orderly charging of multiple stationary electric vehicles" disclosed in Chinese patent documents, with the announcement number CN107627879A, which includes the user sending a charging request; the main control system receiving the charging request instruction and performing charging sequencing; the main control system sending an orderly charging instruction to the charging system; the charging system receiving the charging instruction and transmitting it to the automatic navigation vehicle; the automatic navigation vehicle driving to the location of the electric vehicle to be charged for charging. The target of this scheme is prohibited vehicles, which are often vehicles that have run out of power and stopped on the road. For these vehicles, traffic congestion is usually caused, and a lot of waiting time is required. It is impossible to arrange time reasonably, and the charging efficiency is low. Summary of the invention

The isolation wall is two 50mm thick partition walls, with a 1000mm deep space between the partition walls, which can be used to place the control box. Passage doors are set on both sides of the mobile box.

[0013] A method for charging an electric vehicle in an uninterrupted power supply mobile cabin comprises the following steps: S1: Each uninterruptible power mobile cabin receives a charging request from an electric vehicle and sends the charging request and status information to a central dispatch server; S2: The charging requests sent by the same electric vehicle to different uninterruptible power mobile cabins are grouped into the same request set, and the uninterruptible power mobile cabins corresponding to the request set are screened and sorted according to the status information and the charging request pairs; S3: dispatching commands and charging strategies in sequence according to the order of the uninterruptible mobile cabins corresponding to each charging request set.

A method for charging an electric vehicle in an uninterruptible mobile cabin, using an uninterruptible mobile cabin charging system for an electric vehicle as claimed in any one of claims 1 to 4, characterized in that: The following steps are involved: S1: Each uninterruptible power mobile cabin receives a charging request from an electric vehicle and sends the charging request and status information to a central dispatch server; S2: The charging requests sent by the same electric vehicle to different uninterruptible power mobile cabins are grouped into the same request set, and the uninterruptible power mobile cabins corresponding to the request set are screened and sorted according to the status information and the charging request pairs; S3: dispatching commands and charging strategies in sequence according to the order of the uninterruptible mobile cabins corresponding to each charging request set.

6. The method for charging an electric vehicle in an uninterrupted mobile cabin according to claim 5, characterized in that: If the electric vehicle is in a moving state, the route that the electric vehicle intends to travel is obtained, and the position that the electric vehicle can reach is estimated based on the remaining power of the electric vehicle, and the route information of the electric vehicle is intercepted; each coordinate point on the route information is taken as the center of the circle, and the rated radius is set to obtain the range of sending the charging request; If the electric vehicle is stationary, the coordinate position of the electric vehicle is taken as the center of the circle, the rated radius is set, and the charging request sending range is obtained; All uninterrupted power mobile cabins within the charging request sending range can receive the charging request sent by the electric vehicle.

7. A method for charging an electric vehicle in an uninterrupted mobile cabin according to claim 5 or 6, characterized in that: The charging request includes the coordinates of the electric vehicle, the number of electric vehicles and the power demand; the status information of the uninterruptible power mobile cabin includes real-time power information, coordinate information and working status information, and the working status information includes the idle and busy status of the charging pile.

8. The method for charging an electric vehicle in an uninterrupted mobile cabin according to claim 7, characterized in that: In step S2, the uninterruptible mobile cabin screening process with only one request set includes: For all charging requests in the request set, find out the status information of the uninterruptible mobile cabin corresponding to the charging request; Eliminate the uninterruptible mobile cabins whose remaining power in the status information is not enough to meet the power demand of the charging request and their corresponding charging requests in the request set; For the uninterrupted power mobile cabins in the same request set, they are sorted from small to large according to the sum of the moving distance of the electric vehicle and the moving distance of the uninterrupted power mobile cabin.

9. The method for charging an electric vehicle in an uninterrupted mobile cabin according to claim 7, characterized in that: In step S2, the screening process for the uninterruptible mobile cabin with multiple request sets includes: All request sets are traversed in pairs to determine whether the uninterruptible mobile cabins received by the charging requests in the two request sets overlap; if so, the overlapping uninterruptible mobile cabins are selected for optimal screening; otherwise, the corresponding uninterruptible mobile cabins in the other request set are used to determine whether they can supply power to the electric vehicles in this request set; The remaining driving range of the electric vehicle is estimated based on the remaining power of the electric vehicle, and the energy consumption cost of the target uninterruptible power mobile cabin and the electric vehicle is calculated. If the energy consumption cost is less than the set energy consumption threshold, and the remaining power of the target uninterruptible power mobile cabin meets the sum of the power demand of all charging requests it has received, then the target uninterruptible power mobile cabin is added to the uninterruptible power mobile cabin corresponding to the current request set, otherwise, it remains unchanged until all the target uninterruptible power mobile cabins corresponding to the request combination are traversed; Calculate the charging energy consumption cost of each charging strategy respectively, sort them from low to high according to the charging cost, and select the best one.

10. A method for charging an electric vehicle in an uninterrupted mobile cabin according to claim 8 or 9, characterized in that: Determine whether the number of electric vehicles that need to be charged in the same uninterruptible power mobile cabin at the same time exceeds the upper limit of the number of charging piles; If so, sort by distance, remove the electric vehicle request farthest from the uninterruptible mobile cabin, and return to recalculate the charging strategy; otherwise, proceed to step S3 to perform mobile power station scheduling.
