Hella 012767371 Intelligent Battery Sensor (IBS) for GM Vehicles

The Hella 012767371 Intelligent Battery Sensor (IBS) is a precision OE-quality component designed to continuously monitor the state of your vehicle's 12V battery. Mounted directly on the battery's negative terminal, this sensor enables the vehicle's energy management system to make real-time decisions about charging behavior and electrical load distribution.

Key Features:

• Tri-Parameter Measurement: Accurately measures battery voltage, current, and temperature for comprehensive battery health monitoring
• Battery State Reporting: Provides continuous data on State of Charge (SOC), State of Health (SOH), and State of Function (SOF)
• LIN Protocol Communication: Communicates seamlessly with the vehicle's control unit via the standardized LIN (CI bus) interface
• Shunt-Based Current Measurement: Integrated shunt resistor attaches to the vehicle's load path for accurate indirect current measurement
• Cast Housing: Electronics housed in a durable cast enclosure with a plug connector for reliable, long-term performance in harsh under-hood environments
• OE-Grade Engineering: Manufactured to original equipment standards — Hella is the global market leader in intelligent battery sensor technology
• Compact Design: Low-profile form factor mounts directly on the negative battery terminal without requiring significant space

The Hella IBS plays a critical role in modern vehicle energy management. By supplying precise battery data to the vehicle's ECU, it supports intelligent alternator control, start-stop system optimization, and early detection of a weakening battery — helping reduce CO2 emissions and minimizing the risk of an unexpected no-start condition. This is a direct OE replacement sensor built with the same engineering standards as the parts originally installed at the factory.
