Description

A heavy truck battery swap station control system and method compatible with different battery swap modes

[0001] The present application claims priority to the Chinese patent application No. 202410467010.X filed on April 18, 2024, and entitled "A heavy truck battery swap station control system and method compatible with different battery swap modes", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of new energy battery swap stations, and in particular to a heavy truck battery swap station control system and method compatible with different battery swap modes. BACKGROUND

[0003] With the rapid development of the logistics transportation industry, heavy trucks, as an important means of transportation, have gradually shifted from traditional refueling to more environmentally friendly and efficient battery swapping. Battery swap stations, as a key facility supporting this transition, are of great significance to heavy truck battery swapping.

[0004] Currently, the station control system of a battery swap station, through the cooperation with devices such as Radio Frequency Identification (RFID), Telematics Box (TBOX), Programmable Logic Controller (PLC), and depth camera, realizes unmanned intelligent battery swapping, significantly improves battery swapping efficiency, and reduces operating costs.

[0005] However, there are some problems in the current interactive mode of heavy truck battery swap stations. First, the interactive mode between the vehicle and the battery swap station is single, and a battery swap station can only support one type of interactive mode - station-connected vehicle or vehicle-connected station for battery swapping. This situation leads to the need for two different control type battery swap stations to support two types of interactive mode vehicles for battery swapping, resulting in a doubling of costs. Moreover, vehicles must go to a designated battery swap station for battery swapping, affecting battery swapping efficiency and user experience. Second, the vehicle-connected 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 swapping area truly needs to be swapped, leading to waste of battery swapping resources and safety problems. Finally, for overhead battery swap stations, the descent height of the trolley controlled by the PLC controller is fixed, but battery swap vehicles of 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 swapping efficiency.

[0087] In order to better understand the scheme of the present application, the technical scheme of the present application will be further described below in combination with an intelligent station control system of a heavy-duty truck battery swap station.

[0088] Embodiment 4

[0089] The embodiment provides an intelligent station control system of a heavy-duty truck battery swap station, which is used for realizing heavy-duty truck battery swap, as shown in FIG. 4, and includes a battery swap station station control device, a station control subsystem, a PLC control subsystem and a vehicle end controller, wherein:

[0090] Optionally, the station control subsystem can correspond to the station control system in the above embodiment; the PLC control subsystem can use a battery swap controller as a core component to perform a control task; the vehicle end controller can correspond to the vehicle controller in the above embodiment; the battery swap station station control device can be integrated with a radio frequency identification system, a vision system and a charger. The battery swap controller can be a PLC controller.

[0091] The battery swap station station control device is in communication connection with the station control subsystem, the battery swap station station control device is connected with the PLC control subsystem, and the battery swap station station control device is controlled by the PLC control subsystem;

[0092] The vehicle end controller is in communication connection with the station control subsystem, the PLC control subsystem is in communication connection with the station control subsystem, and when the vehicle end controller is disconnected from the station control subsystem during the heavy-duty truck battery swap process, the communication between the vehicle end controller and the station control subsystem is automatically reconnected through the PLC control subsystem.

[0093] In further embodiments, the heavy-duty truck battery swap includes the following links:

[0094] The vehicle end controller initiates vehicle authentication to the station control subsystem. After vehicle authentication is passed, the hand brake is checked, the vehicle state is checked, and the heavy truck starts battery replacement when the battery replacement condition is met. The heavy truck battery replacement includes vehicle position recognition, vehicle hand brake detection, high voltage state detection, grabbing the vehicle end battery, and placing the battery to the vehicle end.

The optical fiber line is used to connect the depth camera device and the station control subsystem, ensuring signal transmission and solving the problem.

[0108] The embodiment further provides the following content on the basis of Embodiment 4.

[0109] The battery replacement station station control device includes a battery replacement station charger (also the charger described in Embodiment 1). As shown in FIG. 9, the battery replacement station charger is in communication connection with the station control subsystem. The battery replacement station charger reports the battery code of the battery compartment to the station control subsystem to replace the empty battery code uploaded by the vehicle end controller.

[0110] In a further embodiment, the battery replacement station charger reports the battery code of the battery compartment to the station control subsystem, as shown in FIG. 10, specifically:

[0111] The battery replacement station charger reports the battery code of the battery compartment to the station control subsystem.

[0112] The station control subsystem requests the vehicle end state query from the vehicle end controller.

[0113] When the vehicle end controller receives the vehicle end state query, if the power is turned on after the battery replacement is completed, the battery code is returned to the station control subsystem. If the power is turned off after the battery replacement is completed, the vehicle end controller is disconnected from the station control subsystem, and the station control subsystem receives the empty battery code.

[0114] The battery code of the battery compartment is used to replace the empty battery code.

[0115] The embodiment solves the problem that the battery code cannot be obtained after the battery is installed during the battery replacement process because the high voltage is not turned on. The vehicle end controller cooperates with the battery replacement station charger to obtain the battery code, solving the problem.
