An energy storage device based on bus time division multiplexing

Abstract

The utility model relates to battery management technical field especially, more particularly to a kind of energy storage device based on bus time division multiplexing, it is applied to the battery pack with at least two energy storage components built-in, comprising: battery parameter acquisition module is set in the battery pack, with the energy storage component one-to-one correspondence, for the parameter data of the energy storage component is collected;Master module is set in the battery pack, for receiving the parameter data of the energy storage component;Time division multiplexing controller, with the master module and energy storage component one-to-one correspondence, with fixed period alternate switch power supply mode and communication mode;Time division multiplexing bus, respectively connect the time division multiplexing controller on the master module and energy storage component.The utility model aims to provide a kind of energy storage device based on bus time division multiplexing, using the technical scheme provided by the utility model solves the technical problem that multiple cable harness exists between current electric core and BMS to realize electric core data acquisition.
