DRIVE
March 17, 2022
Disclosed is a power-supplying and driving circuit of an active equalization matrix switch of a battery management system of a vehicle. The power-supplying and driving circuit includes a boost circuit, a constant current source circuit and a driver. The boost circuit includes a first input end and a first output end; the constant current source circuit includes a constant current driving signal output end; the first input end is connected to the positive pole of a battery pack of a matrix switch circuit; the first output end is connected to the constant current source circuit to provide high potential for the constant current source circuit to drive the matrix switch circuit; the constant current driving signal output end is connected to the matrix switch circuit 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.
