This study addresses the shortcomings of existing lithium-ion battery pack detection systems and proposes a lithium-ion battery monitoring system based on NB-IoT-ZigBee technology.
To verify the performance and measurement accuracy of the battery monitoring system, tests will be conducted on the data reception, data visualization, data storage, data fitting, and alarm functions. The collected values of the temperature, voltage, and current will be compared with those obtained from voltmeters, ammeters, and thermometers.
However, the current large-scale battery pack monitoring systems exhibit certain design flaws: (1) wired communication leads to cable harness problems such as connection failure, high cost, heavyweight, and complex design; and (2) insufficient monitoring data, preventing timely warnings [ 11, 12, 13 ].
Once the connection is successful, the operational data of the lithium-ion battery can be displayed not only on the local host computer, but also on the local monitoring center. Figure 11. Server program. Figure 12. Client program. 3.2.5. Warning Function
