Detailed Description
The invention discloses a bus priority charging method based on a cloud platform at a bus charging station, wherein the cloud platform is in communication connection with charging piles in the bus station, the charging piles on the bus station are divided into high-power output charging piles and low-power output charging piles, the output power of the high-power charging piles is 360KW, and the output power of the low-power charging piles is 240 KW.
The bus priority charging method specifically comprises the following working steps:
a) the method comprises the steps that the trip line, the battery capacity and the vehicle information of a bus charged at the bus charging station are recorded into a cloud platform, the cloud platform divides the charging priority of the bus into a high-priority bus and a low-priority bus according to the length of the trip line, the high-priority bus is charged in a matching mode through a high-power charging pile, and the low-priority bus is charged in a matching mode through a low-power charging pile;
b) after the bus enters a charging station and establishes charging connection with a charging pile, the charging pile sends the vehicle information to a cloud platform;
when the cloud platform confirms the battery capacity S of the bus according to the authentication analysis result Fruit of Chinese wolfberry And when the set threshold value F is less than or equal to the preset threshold value F, the cloud platform replies that the request charging is successful, and power supplement is started.
When the cloud platform confirms the battery power S of the bus according to the authentication analysis result Fruit of Chinese wolfberry When the charging request is greater than the set threshold F, the platform replies that the charging request fails, and the vehicle does not have the power supplementing requirement.
As a further explanation of the embodiment, the vehicle information in step a) includes a license plate number, a VIN code, and a vehicle number; the high-priority bus in the step a) is a bus with the number of round trip kilometers being more than or equal to 20, and the low-priority bus is a bus with the number of round trip kilometers being less than 20.
As a further explanation of this embodiment, when S Supplement device ≥S Consumption unit When the threshold value F = S in step b) Consumption unit (ii) a When S is Consumption unit ＞S Supplement device A threshold value in b)
