AGV automatic charging device, system, and method

Abstract

The invention provides an AGV automatic charging device, system, and method. The AGV automatic charging device includes an intelligent charging station body, one or more charging units, and one or more battery transfer devices, wherein the intelligent charging station body is used for forming a space for charging and replacing a to-be-charged AGV battery; the charging units are arranged in an intelligent charging station and electrically connected with a charging power source for charging the to-be-charged AGV battery; the battery transfer devices are mounted in the intelligent charging station for carrying the AGV battery between the AGV and the charging units.

Description

technical field [0001] The present disclosure relates to the field of warehousing and logistics, and more specifically, relates to an automatic charging device, system and method for AGV battery replacement. Background technique [0002] With the rapid development of artificial intelligence, the application of AGV (Automatic Guided Vehicle, automatic guided transport vehicle) is becoming more and more extensive. The current AGV operating power is generally a lithium-ion battery. Most AGVs do not have the function of automatically replacing the power supply when the AGV is running. After starting the operation, a small number of AGVs use manual battery replacement. [0003] In the process of realizing the disclosed concept, the inventors found that at least the following problems exist in the prior art: [0004] 1) In order to facilitate the charging of AGV cars, charging piles are generally installed near the car. The increase in the number of charging piles can certainly ...

AI Technical Summary

Problems solved by technology

[0004] 1) In order to facilitate the charging of AGV cars, charging piles are generally installed near the car. The increase in the number of charging piles can certainly improve efficiency, but since the charging piles are all open, there are great safety hazards in the charging process, especially In places with high fire protection level such as warehouses; and batteries are flammable and explosive items, there will be safety hazards if people frequently enter the charging area during the charging process;

[0005] 2) When the AGV car adopts the automatic charging method, the power supply is likely to generate a high temperature alarm when charging in a high temperature environment in summer, because the battery temperature will increase with the charging time and charging current during the charging process of the lithium battery. When the temperature rises to the set value After that, a high temperature alarm will occur; and when the ambient temperature is relatively low in winter, the lithium battery charging will be automatically cut off due to the low temperature, which will affect the charging efficiency and cause inconvenience in use;

[0006] 3) When the AGV battery power is low, the AGV car needs to run to a fixed charging point, and the operation can only be performed after the position is fully charged, so the waiting time for charging is long, which reduces the operating efficiency of the AGV;

[0007] 4) Using manual battery replacement will consume a lot of manpower, and personnel will also need to work 24 hours a day with the AGV car, and there will be man-machine mixed operations during the operation process, which is prone to safety accidents
