Abstract

The invention relates to the technical field of lithium battery management. The lithium battery management circuit for the dust collector comprises a detection module, a main control module, a drivingmodule and a switch enabling module, the detection module, the driving module and the switch enabling module are all electrically connected with the main control module, and the switch enabling module is electrically connected with the detection module; the main control module is used for controlling the detection module, the driving module and the switch enabling module to work; the detection module is used for detecting an electrical signal and a charger state signal, and feeding back the detected electrical signal and the charger state signal to the main control module; the driving moduleis used for driving an external charging and discharging switch tube and driving an external indicating lamp to carry out fault indication. And the switch enabling module is used for controlling the power consumption of the main control module. The lithium battery management circuit for the dust collector is simple in structure, easy to implement and low in cost.

Description

technical field [0001] The invention relates to the technical field of lithium battery management, in particular to a lithium battery management circuit for a vacuum cleaner. Background technique [0002] Lithium batteries are currently the focus of the new energy industry, with the advantages of high energy density and small size, but due to stability and safety issues, lithium batteries need to increase battery management and protection. At present, cordless home appliances are the main trend at present, but the cost of the current analog front-end solution is relatively high, and the function of the hardware solution is insufficient. It needs to be equipped with an MCU to cooperate with it, which increases the complexity. Contents of the invention [0003] The invention provides a lithium battery management circuit for vacuum cleaners, which solves the problem of high cost and complicated lithium battery management in the related art. [0004] As an aspect of the prese...
