Abstract: The present disclosure provides a battery management system with protection and equalization functions including a dedicated battery management IC, a plurality of sampling circuits and a plurality of execution circuits. A battery protection module and an equalization module are integrated in the dedicated battery management IC. The sampling circuits and the execution circuits are coupled between the dedicated battery management IC and a lithium battery pack, respectively. The sampling circuit collects parameters including voltage, charge-discharge current and battery temperature of the lithium battery pack and inputs them into the dedicated battery management IC for analysis and processing. The dedicated battery management IC outputs control signals to the execution circuits according to a result of the analysis and processing of the parameters, to control the execution circuits to perform battery protection function and voltage equalization function of the lithium battery pack.
