Energy storage battery management system

Abstract

An energy storage battery management system comprising a power supply isolation unit, a high-voltage acquisition unit, and a communication isolation unit. The power supply isolation unit is configured to enable an initial low-voltage signal to sequentially undergo primary isolation of a first transformer and secondary isolation of a second transformer so as to obtain a second voltage, convert the second voltage into a target operating voltage, and provide the target operating voltage to the high-voltage acquisition unit. The high-voltage acquisition unit is configured to acquire battery cluster information, convert the battery cluster information into a digital signal form, and provide the battery cluster information in the digital signal form to the communication isolation unit. The communication isolation unit is configured to enable the battery cluster information in the digital signal form to sequentially undergo primary isolation of a third transformer and secondary isolation of a fourth transformer, and then transmit same to a microcontroller unit, so as to allow the microcontroller unit to generate a battery cluster control instruction on the basis of the battery cluster information.
