At present, there are many varieties of AGV cars, and the choice of AGV battery is even more so. How to choose AGV lithium battery? In recent years, we have summarized the following points in cooperation with many AGV car customers, hoping to be helpful to you. Topband lithium battery will share with you:
At present, the lithium batteries used in AGV cars mainly include: ternary lithium batteries and lithium iron phosphate batteries. Here is a brief introduction to their differences: relatively speaking, ternary has the advantages of high monomer voltage, light weight, and good low temperature performance, while its 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. The advantages of lithium iron phosphate batteries are high safety and long cycle life. The disadvantage is that the energy density is low, and the whole battery is heavier. Its monomer rated voltage is 3.2V, and its working voltage is 2.5V-3.65V. Therefore, when choosing agv batteries, we can comprehensively determine the battery's communication protocol, voltage, weight, ambient temperature, safety, and cycle life. Battery specification model.
Protocol
At present, the communication protocols of AGV car battery mainly include: RS485, RS232, CAN. The BMS module of the battery is selected according to the communication protocol.
Operating Voltage
Here, the voltage and material of the lithium battery should be determined by considering the rated voltage and the maximum voltage of the output terminal. The rated voltage of the battery should not be lower than the rated voltage of the motor. However, the full voltage of the battery should not be higher than the maximum voltage of the device. Therefore, it is sometimes seen that the voltage of the agv battery is a 12-series ternary lithium battery with a full voltage of 50.4V, instead of the commonly used 24V or 48V.
Energy used
If the power consumption is large or high-power discharge, such as the lithium battery capacity exceeds 1.5 kWh, it is recommended to use iron-lithium batteries if the weight and size can be satisfied, because the safety of use must be considered.
Discharge power
If the discharge current is above 120A, it is also recommended to use iron-lithium batteries.
Use environment
If working in high temperature or harsh road conditions, lithium iron phosphate batteries can be used. Ternary lithium batteries can be used in extremely low temperature conditions.
Manufacturer
Considering the cost of AGV lithium battery, after-sales cost and unexpected conditions during transportation, it is necessary to choose a professional AGV battery manufacturer to customize. And this kind of agv battery mainly investigates the battery cell, BMS template (especially with communication protocol), and assembly process. Authentic battery cells and BMS solutions are selected from first-line manufacturers.
