This paper from Texas Instruments compares shunt and hall-based isolated current sensing solutions in HEV/EV subsystems. Global market for Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) is rapidly growing as these vehicles offer higher fuel-efficiency and lower emissions compared to gasoline or diesel vehicles and use power from renewable energy sources.

To control energy flow and optimise efficiency in HEV/EV powertrain subsystems such as Traction Inverters, OnBoard Chargers (OBC), DC-DC converters, and Battery Management Systems (BMS), precise and accurate current measurement is essential.

These high-voltage subsystems need to measure large currents at high common-mode voltages. For technical and regulatory reasons, the current measurements require isolation as well as very high performance in harsh automotive environments
