Current & Voltage Sensors for Electric Vehicles and Charging
From battery management systems to fast DC chargers, Contisys sensors deliver the precision, bandwidth, and isolation voltage required for next-generation electric mobility.
EV & Charging Measurement Challenges
EV platforms compress more power into smaller envelopes every year. Battery packs now operate at 400 V or 800 V DC, DC chargers push 250 A to 500 A in bus bars, and safety certification demands verified isolation. Sensors must deliver high accuracy across this dynamic range while surviving automotive-grade vibration and thermal cycling — all at a cost that scales to mass production.
Why Contisys for EV & Charging Infrastructure?
Wide Dynamic Range
Single sensor covers ±3× nominal current without saturation — ideal for battery charge/discharge profiles.
Automotive-Grade Testing
ISO 16750-2/3 electrical and mechanical stress compliance on qualified products.
Up to 8 kV RMS Isolation
Reinforced insulation suitable for 800 V battery architectures and DC fast charging.
Scalable Volume Supply
PCB-mount and bus-bar-mount variants designed for SMT assembly and automated production.
Key Use Cases
Battery Management (BMS)
Pack-level charge/discharge current monitoring for 400 V and 800 V battery platforms.
On-Board Charger (OBC)
AC input and DC output current measurement for 3-22 kW on-board chargers.
DC Fast Charger
High-current DC output sensing for 50-350 kW public charging infrastructure.
Traction Inverter
Phase current sensing for high-bandwidth permanent-magnet motor control.
