Method and arrangement for determining the starting ability of a starter battery of an internal combustion engine
First Claim
1. A method of determining a starting ability of a starter battery of an internal combustion engine, comprising the steps of:
- determining a charge status of the starter battery, the charge status having an influence on the starting ability;
determining a temperature that has an influence on the starting ability;
one of calculating and determining an average voltage drop of the starter battery during a starting phase of a starter motor that is in an operative connection with the starter battery; and
estimating the starting ability of the starter battery by comparing the one of calculated and determined average voltage drop with a threshold value.

Abstract
A method of determining the starting ability of a starter battery of an internal combustion engine, according to which a charge status of the starter battery is determined, which has an influence on starting ability. Also determined is a temperature which has an influence on starting ability, in particular the temperature of the starter battery. Moreover, an average voltage drop of the starter battery during a starting phase is calculated or determined, in particular during a turn-over phase of a starter motor, which is in an operative connection with the starter battery. The starting ability of the starter battery is estimated by comparing the calculated or determined average voltage drop with a threshold value.
