As reviewed in my earlier article, accurate monitoring of battery voltage, current and temperature is necessary to ensure the safe operation of battery-powered systems such as vacuum cleaners, power tools and e-bikes. In this article, I will focus on voltage monitoring of lithium-based batteries.
In this article, I will focus on voltage monitoring of lithium-based batteries. A key requirement of safety standards for lithium-based battery systems is that the cells should only operate within the specified voltage range provided by the cell manufacturer.
The detection method of battery parameters in battery management system is simple and the accuracy is limited [, , ], but the accuracy of parameters is the direct factor affecting the fault diagnosis results. Wang et al. proposed a model-based insulation fault diagnosis method based on signal injection topology.
The system uses wireless communication between a central monitoring device and individual battery measurement devices. The monitoring device sends voltage measurement commands to the battery devices at regular intervals. The battery devices measure voltage at those times.
