Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy battery swap stations, in particular to a heavy truck battery swap station control system and method compatible with different battery swap modes. BACKGROUND

[0002] With the rapid development of the logistics transportation industry, heavy trucks as important transportation tools, their energy supply mode has gradually shifted from the traditional refueling mode to a more environmentally friendly and efficient battery swap mode. Battery swap stations, as a key facility to support this transition, are of great significance to heavy truck battery swapping.

[0003] Currently, the station control system of the battery swap station cooperates with devices such as Radio Frequency Identification (RFID), Telematics Box (TBOX), PLC controller (Programmable Logic Controller, PLC), and depth camera to realize unmanned intelligent battery swapping, significantly improving battery swap efficiency and reducing operating costs.

[0004] However, the current interactive mode of heavy truck battery swap stations has some problems. First, the interactive mode between the vehicle and the battery swap station is single, and a battery swap station can only support one interactive mode - station-to-vehicle or vehicle-to-station battery swap for vehicles. This situation leads to the need for two different control type battery swap stations to support two interactive modes for vehicle battery swap, resulting in a doubling of costs, and vehicles must go to a designated battery swap station for battery swap, affecting battery swap efficiency and user experience. Second, the vehicle-to-station mode has the problem of multiple vehicles connecting to the battery swap station at the same time. In this case, the battery swap station often has difficulty accurately distinguishing whether the vehicle parked in the battery swap area actually needs to be swapped, resulting in waste of battery swap resources and safety problems. Finally, for overhead battery swap stations, the descent height of the trolley set by the PLC controller is fixed, but battery swap vehicles using different interactive modes usually use different battery frames, and the required descent height is different. This difference prevents overhead battery swap stations from effectively swapping vehicles using different battery frames, thereby limiting their scope of application and battery swap efficiency. SUMMARY

[0005] To solve the above-mentioned problems of single battery swap interactive mode, inability to distinguish between battery swap vehicles when multiple vehicles connect to the battery swap station at the same time, and low battery swap efficiency, the present application proposes a heavy truck battery swap station control system and method compatible with different battery swap modes, which is compatible with different battery swap interactive modes, realizes full-automatic battery swap for vehicles, supports distinguishing between battery swap vehicles when multiple vehicles connect to the battery swap station at the same time, and effectively improves battery swap efficiency.
