　　With the development of science and technology, more and more places are using automatic handling robots, also known as AGVs, such as express delivery, warehouses, etc. There are so many AGV trolleys, not to mention the lithium batteries in the AGV power battery pack. So, how to choose the corresponding lithium battery pack is particularly important, so let's talk about the lithium battery manufacturer below

　　At present, the lithium batteries used in AGV power battery packs and small cars are mainly ternary lithium batteries and lithium iron phosphate. Here is a brief introduction to these differences. Relatively speaking, in monomers, ternary monomers have high voltage, light weight, and good low-temperature performance, but their disadvantages are short cycle life and poor stability. The rated voltage of its monomer is 3.6V, and the working voltage is 3.0V-4.2V. However, the advantages of lithium iron phosphate batteries are high safety and long cycle life. The disadvantage is low energy density and the entire battery pack is heavy. The rated voltage of its single unit is 3.2V, and the working voltage is 2.5V-3.65V. Not just individual units, some AGV shopping carts are also made using cylindrical units, which can be used even in narrow spaces.

　　Actually, many companies do not know whether to choose ternary lithium batteries first. Is it better to use lithium iron phosphate batteries? Lithium battery manufacturers suggest that battery specifications and models can be determined through a comprehensive consideration of battery communication protocol, voltage, weight, operating environment temperature, safety, and cycle life.

　　1. Communication protocol

　　At present, the communication protocols for AGV power battery packs are mainly RS485 and CAN. Select the BMS module for the battery based on the communication protocol.

　　2. Voltage

　　The nominal voltage is calculated based on the rated voltage of the machine and is the voltage at the output end. Like a 24V machine, if ternary is used, the rated voltage is 25.9V, and if lithium iron phosphate is used, the rated voltage of the battery is 22.4V.

　　3. Electricity consumption

　　Considering the size of capacity, the main factor to consider is the size of space. When space is limited, it is recommended to use a ternary lithium battery pack. The reason for this is as mentioned above, because the volume of ternary lithium is smaller than that of iron lithium.

　　4. Discharge power

　　This mainly determines the size of its protective board and the amount of overcurrent.

　　5. Usage environment

　　When working in environments with high temperatures or poor road conditions, lithium iron phosphate batteries can be used. Especially at low temperatures, ternary lithium batteries can be used.

　　6. Manufacturer

　　Considering the manufacturing costs, after-sales costs, and unexpected situations during transportation of lithium batteries in AGV power battery packs, it is necessary to choose a professional AGV battery manufacturer for customization. This type of AGV power battery pack mainly examines battery cells, BMS templates, especially assembly technology with communication protocols.
