Advanced Pressure Sensors for Battery Cooling Systems in EVs

New high-precision pressure sensors have been developed specifically for monitoring and controlling cooling systems in electric vehicle battery packs. These sensors provide accurate, real-time pressure data in harsh automotive environments, helping to optimize thermal management, improve safety, and extend battery life.

Key Features

• High accuracy and excellent long-term stability
• Wide operating temperature range suitable for automotive use
• Robust design resistant to vibration and media contamination
• Analog and digital output options (including SENT, LIN)
• Fast response time for dynamic pressure monitoring
• AEC-Q100 / IATF 16949 qualified variants available

These pressure sensors play a critical role in liquid-cooled battery systems by monitoring coolant pressure, detecting leaks, ensuring proper flow, and enabling predictive maintenance in high-voltage battery packs.

Target Applications

• Electric vehicle battery thermal management systems
• Battery cooling loops and pumps
• High-voltage battery packs (400V and 800V)
• Hybrid and full electric commercial vehicles

With the growing adoption of larger and higher-voltage battery packs, precise pressure monitoring has become essential for safe and efficient thermal management in modern EVs.
