1. A power-supplying and driving circuit of an active equalization matrix switch of a battery management system, comprising a boost circuit, a constant current source circuit and a driver, wherein the boost circuit comprises a first input end and a first output end;
the constant current source circuit comprises a constant current driving signal output end;
the first input end of the boost circuit is connected to the positive pole of a battery pack of a matrix switch circuit;
the first output end of the boost circuit is connected to the constant current source circuit so as to provide high potential for the constant current source circuit to drive the matrix switch circuit;
the constant current driving signal output end of the constant current source circuit is connected to the matrix switch circuit so as to drive the matrix switch circuit; and
the driver is used for controlling the constant current source circuit to output a constant current driving signal.
