How should I choose a lithium-ion battery for AGV trolleys?

When choosing AGV lithium-ion batteries, we can determine the battery specifications and models from the comprehensive considerations of the battery's communication protocol, voltage, weight, use environment temperature, safety, and cycle life. 1. Communication protocol At present, the important communication protocols of AGV trolley lithium-ion battery are: RS485, RS232, CAN, and the BMS module of the battery is selected according to the communication protocol. 2. Voltage Select the voltage and material of the lithium-ion battery according to the rated voltage and maximum voltage of the output terminal. The rated voltage of the lithium-ion battery should not be lower than the rated voltage of the motor; the full-charge voltage of the lithium-ion battery should not be higher than the maximum voltage of the device. Voltage. Therefore, we often see that the voltage of the AGV lithium-ion battery is a 12-string ternary lithium-ion battery with a full voltage of 50.4V, instead of the commonly used 24V or 48V. 3. Power consumption such as high power consumption or high-power discharge. Assuming that the capacity of the lithium-ion battery exceeds 1.5 kWh, if the weight and size can meet the conditions, and from the perspective of safety, it is recommended to use lithium iron phosphate batteries. 4. If the discharge power is above 120A, it is also recommended to use lithium iron phosphate batteries. 5. Operating environment If operating in high temperature or harsh road conditions, lithium iron phosphate batteries can be used, and AGV special ternary lithium ion batteries should be used in extreme low temperature conditions.
