“Fluxgate Current Sensor Based on H-Bridge” takes the H-bridge-based fluxgate current sensor technology as the core, aiming at the detection accuracy of electric vehicle BMS current sensor is not high enough to accurately measure large current and small current at the same time and sensor power supply and The single power supply mismatch technical problem of BMS provides a design scheme of a fluxgate current sensor with a single excitation core. Using H-bridge circuit to drive the excitation coil realizes single power supply and simplifies the design of sensor power supply; in addition, the excitation detection circuit with double measuring resistors is constructed to convert the excitation current ie flowing through the excitation coil into equivalently ie1 and ie2 the difference between the two currents, and calculate the average value of the excitation current through the difference equivalent current ie1-ie2 to eliminate the zero drift of the current sensor, thereby improving the small current recognition and measurement accuracy of the current sensor. Compared with traditional schemes, this design method is advanced and suitable for current monitoring needs in electric vehicle BMS.
