摘要： A combustion engine (120) in a vehicle is started by means of an electric starter motor (110) which is diagnosed via measuring means (130, 140), a temperature measurement means (150) and a processor (160). The measuring means (130, 140) are configured to measure technical magnitudes related to the vehicle but representing only a supply voltage (U) to the starter motor and a rotation speed (RPM) of the engine (120). The temperature measurement means (150) is configured to measure at least one temperature (T) related to the vehicle. The processor (160) is configured to determine for the starter motor (110) a status indicator (S) which serves as a measure of the quality of the starter motor's performance. The status indicator (S) is based on the measured technical magnitudes and the at least one temperature (T) related to the vehicle.

摘要： An electric starter motor (110) is arranged so as to start a combustion engine (120). The function of the starter motor (110) is subject to diagnostics by means of measuring elements (130, 140) that measure a supply voltage (U) to the starter motor and an rpm (RPM) of the combustion engine. Based on the measured parameters (U, RPM), a processor (160) determines a status indicator (S) that provides a quality metric for the performance of the starter motor (110). A storage element (170) stores a respective value for the status indicator (S) in connection with a number of activations of the electric starter motor (110) in a data series (M). The processor (160) analyzes the data series (M) and determines, on the basis thereof, whether the function of the electric starter motor (11) is acceptable and, if the function is not determined to be acceptable, generates an error code (E).

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.

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： The present invention relates to a method for providing a dual battery (2) unit,eg for starting batteries for a vehicle, eg a truck, engine, including the steps of arranging two batteries together and clamping the batteries for fixing in a desired mutual position. The method is especially characterized in the further steps of -arranging the batteries (2) lying on one of their sides (3), the battery terminals (5) facing each other on each side of an insulating member (7), -applying a clamping device (8) onto the insulating member between the batteries, and -expanding the clamping device towards each battery by means of two clamping members (9), one against each battery, forcing the batteries against opposing end stops (20, 21). The present invention also relates to a dual battery device and a vehicle.
