Hebei Xinda Changyuan Electric Power Technology Co., Ltd. has applied for a patent for an orderly charging method for electric vehicle charging stations based on smart queuing. This innovation is expected to significantly enhance charging efficiency.
As of May 17, 2025, information from the National Intellectual Property Administration indicates that the company submitted a patent titled “An Orderly Charging Method for Electric Vehicle Charging Stations Based on Smart Queuing”, with the publication number CN119975081A and an application date of March 2025. The patent abstract reveals that this invention outlines a method that involves:
- Receiving requests to join the charging queue remotely, extracting vehicle identification and current location data;
- Utilizing a sliding window mechanism to establish fixed time intervals, collecting data on traffic flow and charging point status changes, and updating queue information based on estimated wait times;
- Assigning charging spots using a priority queue algorithm, ensuring that vehicles closer to the station receive charging opportunities first, based on their distance and estimated wait time;
- Processing simultaneous entry requests from multiple vehicles using a timestamp sorting algorithm based on entry time to determine the order of access;
- Generating navigation paths from each vehicle’s current location to the assigned charging spot and sending this information to the vehicle’s onboard navigation system.
This innovative method is anticipated to greatly improve the efficiency of charging operations.
According to data from Tianyancha, Hebei Xinda Changyuan Electric Power Technology Co., Ltd. was established in 2009 and is located in Baoding City. The company primarily focuses on research and experimental development, with a registered capital of 45.0225 million RMB. The company has participated in 156 bidding projects and holds 15 trademark registrations along with 33 patents, in addition to possessing 8 administrative licenses.
