Abstract

The embodiment of the invention provides an inductive active equalization unit and a hardware indication circuit thereof, and belongs to the technical field of active equalization units. The hardware indication circuit comprises an on-off state detection circuit, the on-off state detection circuit comprises a first resistor, and one end of the first resistor is connected with one end of a first switch of the equalization unit. According to the inductance type active equalization unit and the hardware indication circuit thereof provided by the invention, the switch state detection circuit is connected with the equalization unit, the first NOT gate outputs the first switch indication signal, and the second NOT gate outputs the second switch indication signal; the charging and discharging state detection circuit determines the charging and discharging state of the equalization unit according to the first switch indication signal and the second switch indication signal, and finally the charging and discharging state of the equalization unit is displayed through the charging and discharging LED indication circuit, and the hardware indication circuit is high in portability and strong in applicability, and can accurately display the charging and discharging state of the equalization unit.

Description

technical field [0001] The invention relates to the technical field of active equalization units, in particular to an inductive active equalization unit and a hardware indicating circuit thereof. Background technique [0002] The active equalization technology based on inductive active equalization has been widely used in the battery management system (BMS). Active equalization is mainly to transfer the high energy of the single cell to the low capacity of the single cell, or supplement the lowest capacity of the single cell with the entire group capacity. [0003] However, when the balance unit is working, the working status of the balance unit can only be known by reading the corresponding variables from the program. This requires the owner of the BMS algorithm source code and familiarity with the meaning of the variables in the code. In the daily maintenance or teaching of the battery pack In demonstrations, such conditions are usually not present, so it is difficult to k...
