4 Before starting the engine put a piece of back or tarpaulin on the both the batteries so that in case of accidental
explosion of battery nobody get injured. This is necessary precaution.
5 Start the engine when both the batteries are completely connected.
6 After the engine has started unfasten the jumper cable.

7 After starting the engine, give a sometime to charge the vehicle discharge battery. Let the engine run for at
least 15 minutes to charge.
IBS (Intelligent Battery System) system
The intelligent battery system (IBS) informs you about the current energy status, allowing you to plan your energy
supply. In order to carefully conserve the energy of the vehicle battery, it is necessary to know the state of charge,
ageing and any changes to the battery, as weak batteries are the main cause of vehicle breakdown.

Application of IBS
The intelligent battery sensor (IBS) from HELLA is the key element of vehicle energy management. The IBS
reliably and accurately measures the battery voltage, current and temperature parameters. Information on the
state of charge (SOC), state of health (SOH) and state of function (SOF) of the battery is calculated algorithmically
using these measurements. The IBS is designed to be used in starter, gel and AGM batteries to monitor in-vehicle
starter or consumer batteries. The IBS can be directly integrated into the vehicle’s electrical system with the
standardize LIN protocol. The IBS is attached directly to the negative pole of the battery via the pole terminal.
Alongside the terminal, the mechanical portion of the battery sensor consists of the shunt and grounding bolt. The
shunt is attached to the vehicle’s load path and is used as a measuring resistor to measure the current indirectly.
The ground cable can be conveniently attached to the grounding bolt, e.g. with the optionally deliverable battery
pole adapter. The electronics are located in a cast housing with a plug connector which functions as the interface
to the energy management system. The LIN protocol is the communication interface to the higher-level control
unit. The supply voltage, used simultaneously as the reference voltage for voltage measurement, is provided by
the connection to the positive pole of the battery.
