The technology will be available on a production vehicle in 2006, Bosch said in a statement, without giving details.


By measuring the temperature, current and voltage, the EBS system is used to determine the condition and capability of a car’s battery.


The data, transmitted through a LIN interface, works in conjunction with a car’s energy management system and can be used to ensure enough battery energy is preserved to guarantee a car starts every time it is turned on, even after long periods of non-use.


Information from the sensor also can help optimise alternator and engine functions, allowing for lower fuel consumption, less exhaust emission and a prolonged battery life cycle.
