[0016] Figure 1 FIG. 1 is a schematic diagram of an anti-reverse charging AGV charging circuit according to an embodiment of the present invention. DETAILED DESCRIPTION
[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and the present invention will be further elaborated.
[0018] First, in combination with Figure 1 An anti-reverse charging AGV charging circuit according to an embodiment of the present invention will be described, which is used to prevent the AGV from reverse charging and has a wide range of application scenarios.
[0019] As Figure 1 shown, the anti-reverse charging AGV charging circuit according to an embodiment of the present invention includes: an AGV charging contact 3, a charging control component 2, and an energy storage device 1.
[0020] Specifically, as Figure 1 shown, in this embodiment, the charging control component 2 and the energy storage device 1 are arranged inside the AGV; the positive pole of the AGV charging contact 3 is connected to the input end of the charging control component 2, the negative pole of the AGV charging contact 3 is connected to the negative pole of the energy storage device 1, and the output end of the charging control component 2 is connected to the positive pole of the energy storage device 1; the energy storage device 1 stores electric energy for the operation of the AGV, and the charging control component 2 controls the flow of electric energy. By the charging control component 2, it is ensured that the electric energy can only flow unidirectionally during the charging process, that is, only from the external power supply to the energy storage device 1. It effectively prevents the energy storage device 1 (such as a battery) from discharging reversely during the charging process, thereby protecting the safety of the circuit system and improving the charging efficiency and safety.
[0021] Further, as Figure 1 shown, in this embodiment, the charging control component 2 includes: a diode 21 and a high-current contactor 22; both ends of the high-current contactor 22 are respectively connected to the positive pole of the AGV charging contact 3 and the positive pole of the diode 21, and the negative pole of the diode 21 is connected to the positive pole of the energy storage device 1; the diode 21 and the high-current contactor 22 control the flow of electric energy. The reverse charging can be effectively controlled by the diode 21. When the high-current contactor 22 detects abnormal conditions such as overcurrent, overvoltage, or short circuit, the control circuit can quickly cut off the high-current contactor 22 to protect the safety of the circuit, and the structure is simple and practical.
[0022] Further, as Figure 1As shown, in this embodiment, it further includes: a charger 5 and a track charging plate 4; the track charging plate 4 is arranged on the external AGV track; the charger 5 is connected to the track charging plate 4, and the charger 5 is a constant voltage charger with large current, which is used to output electric energy, and the track charging plate 4 is used to connect the AGV charging contact 3 for electric energy transfer. The charger 5 is connected to the external commercial power supply AC380V. The overall charging is fast, efficient, flexible and convenient.
[0023] As Figure 1 shown, during charging, the AGV charging contact 3 is docked with the track charging plate 4, and the charging control component 2 controls the flow of current. The constant voltage charger with large current 5 delivers electric energy to the energy storage device 1 to achieve charging.

It has the anti-reverse charging function, with a simple circuit structure, strong practicability, high stability, high safety and flexible control.
