The transition to electric mobility places high demands on vehicle electronics. Accurate current measurements are crucial for safety, efficiency and longevity of battery packs and drive systems.
Open-loop Hall-effect sensors measure DC, AC and complex current shapes offer galvanic isolation and are compact, lightweight, have low power consumption, with fast response and linear characteristic over a wide temperature range. Ideal for traction inverters in electric vehicles.
For higher precision, Electrohms supplies closed-loop sensors, with accuracy down to 0.5%, measurement range up to 1000 A, low hysteresis and high thermal stability. They provide stable real-time current feedback under rapidly changing loads.
Sensors are also essential in on-board chargers and Battery Management Systems (BMS). They monitor charge and discharge currents, prevent overcharging and support accurate monitoring of State-of-Charge (SOC) and State-of-Health (SOH) of the battery pack, which extends service life and increases reliability.
Electrohms offers a broad portfolio - Hall effect, fluxgate and GMR - so engineers can achieve the optimal balance of performance, accuracy and cost for safe and efficient solutions in electric mobility.
