Hella 013288911 Intelligent Battery Sensor (IBS) for 12V Vehicle Battery Monitoring

The Hella 013288911 Intelligent Battery Sensor (IBS) is a precision-engineered battery monitoring device designed for modern vehicles equipped with advanced energy management systems. Mounted directly to the negative battery terminal, this sensor continuously measures and reports critical battery parameters to the vehicle's battery management system (BMS) or engine control unit (ECU).

Hella's IBS technology plays a vital role in vehicles with start-stop systems, regenerative braking, and other energy-saving features by providing real-time data on battery state-of-charge (SOC), state-of-health (SOH), and current flow. This allows the vehicle's control systems to make intelligent decisions about alternator output, idle stop activation, and electrical load management — helping to extend battery life and improve fuel efficiency.

Key Features:

• Measures battery voltage, current, and temperature in real time
• Provides state-of-charge (SOC) and state-of-health (SOH) data to the vehicle ECU
• Direct negative terminal mount for accurate current measurement via integrated shunt resistor
• Compatible with vehicles featuring start-stop, regenerative braking, and energy management systems
• OE-quality construction engineered to Hella's original equipment standards
• Communicates via LIN (Local Interconnect Network) bus protocol
• Plug-and-play design for straightforward installation

Hella is a globally recognized OEM supplier trusted by leading European and domestic automakers. The 013288911 IBS sensor is built to original equipment specifications, ensuring reliable integration with the vehicle's existing electrical architecture and battery management systems.
