Client Profile
The client is a multinational automotive manufacturer renowned for its cutting-edge electric vehicles (EVs) and hybrid systems. As part of its commitment to sustainability and technological leadership, the company sought high-accuracy current sensors to enhance battery management efficiency and ensure safety in its next-generation EV platforms.
Challenge
The client faced critical challenges in their EV battery systems:
Precision Requirements: Existing Hall-effect sensors could not meet the stringent accuracy standards (±0.1% or better) required for real-time current monitoring.
Harsh Operating Conditions: Sensors needed to perform reliably in extreme temperatures (-40°C to +150°C) and electromagnetic interference (EMI)-heavy environments.
Supply Chain Complexity: As a global OEM, the client demanded a supplier capable of large-scale production, compliance with IATF 16949 standards, and flexible logistics for JIT (Just-in-Time) deliveries.
Solution
rongtech Power proposed its FG-800 Series Fluxgate Current Sensors, offering:
Ultra-High Accuracy: Achieved ±0.05% linearity error, enabling precise current measurement for battery state-of-health (SOH) and state-of-charge (SOC) calculations.
Robust Design: Enhanced EMI resistance and a wide operating temperature range (-40°C to +150°C) ensured durability in automotive environments.
Customization: Tailored form factors and communication interfaces (e.g., CAN FD, Analog Output) to integrate seamlessly with the client’s control systems.
Global Support: Agile production scaling (up to 500K units annually) and regional warehouses in Europe, North America, and Asia ensured on-time delivery.
Results
Enhanced Performance: The FG-800 sensors improved battery system efficiency by 15%, extending vehicle range by ~7% in prototype tests.
Zero Field Failures: Over 200k sensors deployed in 18 months reported 0ppm (parts per million) field failures, exceeding the client’s 50ppm target.
Cost Savings: rongtech’s localized warehousing reduced logistics costs by 22% versus competitors.
