Intelligent battery sensors (IBS) 12 V, global (Generation 2)

Electrics and ElectronicsEnergy management

Optimal energy management passenger cars, EVs, agricultural vehicles, last mile vehicles, marine applications as well as motorhomes: made possible by the intelligent battery sensors (IBS), in their second generation from HELLA. They measure battery variables such as current, voltage, and temperature in 12 V electrical system environments. 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 HELLA IBS 12 V, second generation, are specially developed to meet the requirements for these applications. Their LIN (CI bus) communication interface passes on information such as battery charge status to the charging system.

 

The IBS are designed to fit precisely on the negative terminal of the battery. 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 ground cable can simply be attached to the earthing bolt. The IBS electronics are located in a cast housing with a plug connector.

Program Overview

Operating voltage Part number Packaging unit

6 – 16.5 V 6PK 013 824-007 100

The package space has been optimized in such a way that installation even in locations with difficult access, e.g. under a seat, is easily possible. Furthermore, this product variant has the latest algorithms for battery condition detection. Reliable statements on charge condition and aging are therefore possible even with higher quiescent currents such as can occur, for example, in mobile homes.
