摘要： 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.

摘要： A combustion engine (120) in a vehicle is started by means of a start system including an electric starter motor (110). The function of the start system is evaluated by means of a test system comprising measuring elements, a starter motor analyzer (160) and a control unit (170). The measuring elements measure a supply voltage to the electric starter motor (110) and an rpm of the combustion engine ( 120) when the starter motor (110) is activated. The starter motor analyzer (160) defines, based on the supply voltage and the rpm, a preliminary status (S) of the start system. Based on the preliminary status (S), the control unit (170) evaluates whether information in addition to the supply voltage and the rpm is needed. If such is the case, an interactive communication process is executed wherein an operator (OP) is called upon to input information (OPInp) to the control unit (170) in at least one process step. An expanded status message (TR) that defines a functional status for the start system is generated by the control unit (170) on the basis of the interactive communication process.
