Energy management at the highest level: The intelligent battery sensors (IBS) from HELLA do just that. They measure battery variables such as current, voltage, and temperature. The measured values provide information on the state of charge (SOC), aging (SOH), as well as the expected starting capability (SOF) of the battery. The intelligent battery sensors therefore permanently monitor key parameters and provide early warning of a weak or defective battery.
The HELLA IBS are designed to fit perfectly around the negative terminal of the battery. The mounting control is done via the pole terminal. As a measuring resistor for indirect current measurement, the shunt component of the battery sensors is attached to the vehicle’s load path, while the existing ground cable can simply be attached to the earthing bolt. The IBS electronics are located in a cast housing with a plug connector. Communication with the higher-level control unit related to the battery’s energy status is done via the LIN protocol.

Program Overview
| Operating voltage | Variant | Part number | Packaging unit |
|---|---|---|---|
| 6 – 16.5 V | Sensor 1 | 6PK 010 842-001 | 1 |

There are two variants of the intelligent battery sensor available. Sensor 1 is the basic version. When monitoring a second battery, sensor 2 is used in the same communication network. A battery pole for screwing on (battery pole adapter) can be ordered as an optional accessory.
