Current Sensing for Electric Vehicles
Since the current required to propel an EV can be in the order of 100’s of amps, current measurement can present a challenge for safety, accuracy, and thermal management. This article discusses current measurement techniques with an introduction to a new magneto-resistive sense technology.
Sensor technology company Crocus Technology has announced a new line of contactless current sensors it says have a signal-to-noise ratio as high as 77 dB and the capacity to measure currents between 500 mA and 1,800 A.

Today, several techniques able to convert a magnetic field to a proportional voltage are available. Magnetic sensors have been used in different applications across a variety of sectors, including magnetic encoders, e-compasses, absolute angle sensors, simple on/off switches, and current sensing.
