Customer ServiceHowever, 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 ].
Since the battery has ohmic and polarization resistances, it has a minimum discharge voltage of 2.75 V, and after a period of standing, its voltage will gradually rise back up so that the minimum voltage in Figure 18 is 3.45 V. During the charging process, the voltage is recorded by both the monitoring platform and the charge-discharge instrument.
During the course of this study, the batteries used for testing were 18650 batteries manufactured by a company called Jiaozuo DFD. These batteries have a rated voltage of 3.7 V and a rated capacity of 2000 mAh. The maximum charging current is 2 A, and the maximum discharging current is 6 A.
The BMS is capable of monitoring individual batteries, collecting various parameter information of the battery pack, realizing the calculation of the battery charge state, and setting up a temperature management system and a three-level protection system to ensure the safe and reliable operation of electric vehicles.
Due to issues with lithium-ion battery materials, the voltage of a single lithium-ion battery is typically between 2.5 and 4.2 V [ 1 ]. Multiple single cells are connected in series and parallel to form battery modules, which meet practical usage requirements, and several battery modules compose larger battery packs connected to the grid [ 9, 10 ].
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.
