<p>An improved method and arrangement for determining a resulting charging duration to be used for charging at least one starter battery in a dual battery system is disclosed. The dual battery system comprises at least one power battery being connected to an electrical system comprising a starter motor and battery charging means, and the at least one starter battery, being connectable in parallel with the at least one power battery. According to the invention, an initial charging duration is determined based on a temperature of the at least one starter battery and on a measure of a behaviour of a starter motor, when the starter motor is activated. Further, the resulting charging duration to be used for charging the at least one starter battery is determined, during charging of the at least one starter battery, based on the initial charging duration and on a relation between a nominal charging voltage and an actual charging voltage being used for charging the at least one starter battery. By the present invention, the resulting charging duration to be used can be determined very exactly by adapting it to the actual parameters having an influence on the quality and efficiency for charging of the starter batteries.</p> |
