EV power systems in battery electric and hybrid vehicles are rapidly advancing toward higher system voltages to support greater efficiency and increased power delivery. In these demanding applications, busbar shunts offer a highly reliable, accurate, and cost-effective solution for current measurement across the vehicle’s high current subsystems. Compared to alternatives such as Hall effect sensors, shunts provide a simple, direct, and linear method of current monitoring, making them an excellent choice for modern electrified vehicle designs.

Stackpole’s HCC series is available in resistance values of 100, 50, and 25 µOhm, enabling exceptionally high current handling of more than 1400 amps with minimal power loss. Its all-welded construction delivers a robust mechanical design along with a clean, linear output for precise current measurement. With multiple resistance values and package sizes available, the HCC provides the flexibility and scalability needed to support a wide range of EV and hybrid power system requirements. Stackpole’s vertically integrated manufacturing has the ability to provide custom sizes, shapes, and resistance values.

The HCC is well suited for critical current sensing and control functions throughout the modern electrified vehicle, including battery management systems (BMS), DC bus measurement, and inverter output current monitoring for propulsion motor drive systems.
