With the continuous development of automation technology, the application of AGV (automatic guided vehicle) in the field of industrial production and logistics is becoming more and more extensive. However, the design and selection of lithium battery system, one of the energy sources of AGV car, is crucial to its performance and stability. This paper will discuss the complete scheme of inspecting the lithium battery system of the AGV trolley, including lithium battery selection, battery management system, charging technology and other aspects, providing reference for the research and application in related fields.

1. Lithium battery selection:
   in the process of inspecting the lithium battery selection of the AGV car, the battery capacity, voltage, cycle life, safety and other factors need to be considered. Common lithium battery types include lithium iron phosphate battery (LiFePO4), lithium manganese oxide battery (LiMn2O4), lithium cobalt oxide batteries (LiCoO2), etc. Different types of lithium batteries have their own characteristics. For example, LiFePO4 batteries have high safety and cycle life, which is suitable for long-time operation scenarios; LiCoO2 batteries have high energy density, it is suitable for scenarios with high capacity requirements. Therefore, when selecting lithium batteries, it is necessary to comprehensively consider various factors according to actual needs and select the most suitable battery type.

2. Battery Management System Design:
   inspection of the battery management system of the AGV car is crucial to the service life and performance of the battery. A good battery management system can realize real-time monitoring of battery status, balanced charging and discharging, overcharge and overdischarge protection and other functions to ensure the safe and stable operation of the battery. In addition, the battery management system should also have remote monitoring, fault diagnosis and other functions, as well as data interaction with the vehicle control system of the AGV to realize the overall management and control of the battery status.

3. Application of charging technology:
   the application of charging technology of inspection AGV car is also an important link. Factors such as charging speed, charging efficiency and adaptability of charging equipment should be considered in the selection of charging technology. Common charging technologies include ordinary socket charging, fast charging technology, wireless charging, etc. When designing and inspecting the lithium battery system of AGV trolley, the layout of charging equipment and the design of charging interface should be considered to ensure the safety and efficiency of charging process and improve the working efficiency and reliability of AGV trolley.

Inspection lithium battery system of AGV trolley the complete scheme needs to comprehensively consider many aspects such as lithium battery selection, battery management system design and charging technology application. Through reasonable selection of lithium battery type,The excellent design of battery management system and the application of convenient and efficient charging technology can realize the performance optimization, endurance improvement and operation stability improvement of the inspection vehicle.
