The direct current one-machine-multiple-charging ordered charging control system according to claim 5, wherein the charging distribution module comprises an information acquisition unit, an inlet unit and a distribution unit, the information acquisition unit is used for realizing the collection of user information, the electric car enters a charging area by controlling the operation of the inlet unit, and the distribution unit distributes the charging module group to charge the electric car.
7. The direct current one-machine-multiple-charge ordered charge control system according to claim 6, wherein the step of the information acquisition unit acquiring user information includes: the information acquisition unit scans codes through a program, authorizes to acquire personal information, obtains the contact information of the user, acquires the contact information of the user through the separation prompting unit after the charging state is disconnected for a set time, prompts the separation of the client, starts the additional money deduction system if the client does not leave, and stops timing money deduction of the additional money deduction system until the vehicle information of the user passes through the exit unit mark.
8. The direct current one-machine-multiple-charge-ordered charge control system according to claim 6, wherein the step of assigning the position of the charge module group by the assigning unit comprises: the distribution unit is used for calling the use power of the power distribution plate A and the power distribution plate B, distributing corresponding charging module groups according to the use power, recording the positions and the numbers of the charging module groups, sending the positions and the numbers of the charging module groups to the client, and conducting code scanning charging and timing by a user.
9. The direct current one-machine-multiple-charge ordered charge control system of claim 7, wherein the operation steps of the additional deduction system comprise:
acquiring the time h of disconnection of the charging state, judging the interval range where the disconnection time h is located, and setting four range values of h1, h2, h3 and h4, wherein h1 is less than h2 is less than h3 is less than h4;
if h < = h1, the extra money deduction system deducts money p=0;
if h1<h<The separation unit performs separation on the user according to the contact way of the user, and if the exit unit detects that the vehicle is separated, the extra money deduction system deducts money P=0; if the exit unit does not detect the vehicle driving away, h2<h<=h3, extra money-deducting system deducts moneya. b and c are set parameter values;
if h3<h<The exit detection unit detects that the car is away, and the additional money deduction system deducts money if the exit detection unit detects that the car is awayIf the exit unit does not detect the vehicle driving away, h>h4, extra money-deducting system deducting money +.>
