However, along with the increase of AGV car quantity, the management of battery charging becomes a big challenge in the factory automation operation.

[0003] The existing AGV charging management system usually adopts the one-to-one charging mode, that is, each AGV car is equipped with independent charging manager and charger, and this architecture can meet the basic charging demand, but there are the following problems:

[0004] For the factory with multiple AGV cars, the independent charging equipment of each AGV car will greatly increase the equipment investment cost.

[0005] The separate charging mode cannot fully utilize the resources of charging equipment, causes the charging equipment to be in the idle state in part of time, and affects the overall charging efficiency.

[0006] In the management of multiple devices, due to the lack of unified management coordination, it can cause charging conflict or battery identification error, increases the complexity and maintenance cost of device use.

[0007] Therefore, the market urgently needs a low-cost, high-efficiency and flexible charging management solution, which can realize the unified management and flexible charging of multiple AGV car batteries under the premise of ensuring safety SUMMARY

[0008] In order to solve the above problems, the utility model provides a low -cost efficient charging management system for automatic carrier can effectively solve the above -mentioned problems.

Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.

[0026] All features disclosed in this specification, or the steps in all disclosed methods or processes, can be combined in any manner, except where mutually exclusive.

[0027] Any feature disclosed in this specification, unless otherwise stated, can be replaced by an alternative feature or replaced by a feature having the same function. That is, each feature is only an example of a series of equivalent or similar features.

[0028] As Figure 1 As shown in the drawings, the present application provides a low-cost and high-efficiency charging management system for an automatic carrier, which aims to reduce the number of charging devices, improve the charging efficiency, and ensure the safety of the charging process through a reasonable design scheme. The core part of the system includes a charging manager, a charger, a relay module, a series charging structure and a charging interface module, has the ability of intelligent identification and flexible charging, can support multiple AGV vehicles to charge at the same time, and dynamically adjusts the charging mode according to the charging demand.

[0029] The charging manager in the charging management system communicates with the management systems of multiple AGV batteries through a CAN bus interface, obtaining the charging demand information of each battery. The task of the charging manager is to identify the unique factory serial number of each battery connected to the system, and to reasonably allocate the charging sequence according to the power situation and charging demand of these batteries. The CAN bus technology enables the charging manager to accurately obtain the status of each battery, thereby effectively avoiding the chaos of charging management and ensuring that the batteries will not be charged due to identification errors. Through this intelligent identification, the charging manager can effectively manage the batteries of up to four AGV vehicles without the need for a separate charging manager for each vehicle, greatly reducing the cost of the system.

[0030] The charger part adopts the design of positive and negative output terminals for providing dynamically adjustable charging voltage and current for connected batteries. The output terminals of the charger are connected to the charging interfaces of multiple AGV batteries through a relay module. The relay module includes at least four relays, and the charging manager controls the working state of each relay through the relay module, thereby controlling the electrical connection state between the charger and each charging interface. Under this design, the charger can dynamically adjust the output voltage according to different charging demands, ensuring the stability and efficiency of battery charging.

[0031] The design of the series charging structure enables multiple AGV batteries to be connected in series. Specifically, multiple charging interfaces are connected together through a relay module to form a battery series group. The charger adjusts the output voltage according to the number of series batteries through the control of the relay module. Since the series structure reasonably matches the charging voltage of the batteries, the charging efficiency is effectively improved, and the problem of voltage mismatch caused by simultaneous charging of multiple vehicles is avoided, ensuring the safety of the charging process.

[0032] The charging interface module is designed with multiple independent charging positions, each equipped with positive and negative interfaces for connecting with AGV batteries. Each charging position is equipped with an indicator light for real-time indication of the current charging status. When the charger is connected to a specific AGV vehicle, the indicator light can clearly show whether the charging is complete, thereby helping users to monitor the charging process in real time. This design enables multiple AGV vehicles to be charged simultaneously, and the charging process is more visualized, reducing the need for manual intervention.

[0033] In order to improve the charging efficiency and ensure safety, the charging manager also includes a battery detection unit, which can detect the voltage of each AGV car battery in real time, and feedback information to the charging manager. The charging manager adjusts the charging sequence and charging capacity through the relay module according to the detection result, so that the AGV car with low battery can be charged preferentially, and the AGV car in the factory can be restored to use in the shortest time. This function improves the availability of the factory AGV car, and avoids the problem of low production efficiency caused by the low battery of a car.

[0034] When multiple AGV cars are charging at the same time, the charging manager intelligently allocates charging priority through optimization algorithm. Specifically, when the charging manager detects that multiple charging interfaces are in working condition, it determines the charging priority according to the remaining battery capacity of each car, so that the AGV car with low battery capacity can be fully charged at the fastest speed. During the idle period of the factory, the charging manager can also choose to charge multiple AGV cars at the same time, maximize the use of charging equipment working time, and improve the charging efficiency and equipment utilization.

[0035] The output end of the charger is also provided with a voltage regulation module, which can dynamically adjust the charging voltage according to the number of series-connected batteries. When the system identifies that the number of connected batteries changes, the voltage regulation module will automatically adjust the voltage output to adapt to the charging needs of different battery packs. This design ensures the flexibility and adaptability of the charging voltage, effectively avoiding the problem of unstable charging caused by voltage mismatch.

[0036] The utility model discloses a reasonable combination of charging manager, charger, relay module, series charging structure and charging interface module and other components, realizes the efficient management and charging of multiple AGV car batteries, reduces the equipment investment cost, improves the charging efficiency, and ensures the safety and stability of the charging process through intelligent management. The charging management system not only solves the high cost problem in the prior art, but also provides an efficient, flexible and safe charging solution for factory automation operation.

[0037] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any change or replacement without creative labor should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited by the protection scope defined in the claims.
