　　Battery manufacturers teach you BMS fault analysis methods for 6LR61 alkaline battery

　　The battery manufacturer teaches you BMS failure analysis methods for 6LR61 alkaline battery. Lithium iron phosphate battery management system BMS, commonly known as battery nanny or battery butler, is an important link between vehicle power batteries and electric vehicles. The lithium iron phosphate battery management system is not only closely related to the battery, but also has various connections with the vehicle system. Among all faults, compared with other systems, battery management system faults are relatively high and difficult to deal with.

　　BMS is an indispensable and important component in power and energy storage 6LR61 alkaline battery, and its cost accounts for about 20% of the total cost of the battery pack on average. As far as power batteries are concerned, they account for 6%-10% of the total vehicle cost of new energy vehicles. The battery management system has low marginal costs and can increase product gross profit margins by expanding production scale and market share.

　　●Observation method

　　When communication interruption or control abnormality occurs in the system, observe whether there are alarms in each module of the system and whether there are alarm icons on the display screen, and then investigate the resulting phenomena one by one.

　　●Fault reproduction method

　　Lithium iron phosphate battery pack BMS vehicles have different faults under different conditions. If conditions permit, try to reproduce the fault under the same conditions as much as possible to confirm the problem point.

　　●Exclusion method

　　When similar interference occurs in the system, each component in the system should be removed one by one to determine which part is causing the impact on the system.

　　●Replacement method

　　When a module has temperature, voltage, control, etc. abnormalities, swap the positions of modules with the same number of strings to diagnose whether it is a module problem or a wiring harness problem.

　　●Environmental Inspection Act

　　When a system failure occurs, such as the system cannot be displayed, we should not rush to consider it in depth because we often overlook some details. First we should look at the obvious things: Is the power plugged in? Is the switch turned on? Are all the wiring connected? Maybe that's where the problem lies.

　　●Program upgrade method

　　When an unknown fault occurs after a new program is burned, causing system control abnormalities, the previous version of the program can be burned for comparison to analyze and handle the fault.

　　●Data analysis method

　　When a control or related failure occurs in the BMS of the lithium iron phosphate battery pack, the data stored in the BMS can be analyzed.

　　With the increase in the number of single lithium batteries, the problem of consistency between batteries has become more prominent. There is the problem of "barrel effect". Each battery needs to be better protected. At the same time, for the overall efficiency, BMS also needs to be improved. Active balancing to get the most out of your battery pack. As the functionality and complexity of lithium iron phosphate battery management systems increase, their value also grows from a few dollars to over tens of thousands of dollars at best.
