Battery monitoring circuit, battery monitoring power consumption balancing method, chip and daisy chain communication system

Abstract

The embodiment of the invention provides a battery monitoring circuit, a battery monitoring power consumption balancing method, a chip and a daisy chain communication system. The battery monitoring circuit comprises a signal communication module and a signal sending module, wherein the signal sending module is used for daisy chain communication; the communication statistical module is used for counting the communication power of the signal communication module of the current battery monitoring circuit; and the discharge control module is used for controlling the battery unit corresponding to the current battery monitoring circuit to discharge according to the communication power of the previous-stage battery monitoring circuit and the communication power of the current battery monitoring circuit. According to the application, the phenomenon that the voltage of each battery unit is inconsistent due to the inconsistent working duration of daisy chain communication of different battery monitoring circuits can be avoided.
