[0001] A SIMULATION SYSTEM

[0002] Technical Field

[0003] The present invention relates to a system which enables electric vehicles to perform simultaneous processes with a plurality of devices and to simulate various scenarios when their charging processes are being carried out.

[0004] Background of the Invention

[0005] Today, the rapid increase in the number of electric vehicles and charging stations increases the number of software development companies operating in this field. While charging processes of electric vehicles are carried out, the communication between the devices and the central system is carried out with the OCPP (Open Charge Point Protocol) protocol. This protocol defines the behavior and message structures of both the devices and the central system. It is critical for technology companies developing centralized systems to be able to effectively test the software they develop to improve system security and performance. Some charging device manufacturers may provide testing devices, however, situations such as limited test scenarios, device failures, connectivity issues and being limited to a single device may be encountered. In this context, the need for a user-friendly testing tool that can perform simultaneous processes with a plurality of devices and simulate various scenarios is gradually increasing.

[0006] For this reason, it is understood that there is a need for a system which enables electric vehicles to perform simultaneous processes with a plurality of devices and to simulate various scenarios when their charging processes are being carried out.The Korean patent document no. KR20240097268, an application included in the state of the art, discloses electric vehicle charger metering performance online detection system and method. The said invention discloses an electric vehicle charger metering performance online detection system and method and belongs to the technical field of electric vehicle charging equipment. The electric vehicle charger metering performance online detection system comprises a system master station, a direct current metering module, a power utilization data acquisition device, a direct current detection meter, a control management module, a metering error calculation module, an operation error monitoring module and an abnormity early warning and work order issuing module. Through continuous exploration and test, the metering error calculation module and the operation error monitoring module are arranged. By means of these modules, the working error, the indicating value error, the billing error and the clock error of the charger can be calculated according to data acquired by the power utilization data acquisition equipment. In this way, online detection of the metering performance of the direct-current charging station can be realized, the detection efficiency of the charger is effectively improved, and the detection cost is effectively reduced.
