Abstract

The invention provides a method (100), a testing arrangement (1) and a vehicle (5) for performing a diagnostic test of an alternator (2). The method (100) comprises: operating (101) an engine (6); providing (102) a signal indicative of a predetermined environmental condition to the alternator (2); providing (102) a signal to the battery (3) based on the predetermined environmental condition 103) output voltage and output current; determining (104) at least one of the following parameters: full battery voltage, voltage and current load of the corresponding battery cell; comparing the determined battery voltage with a predefined and comparing (105) the reference voltage with the reference voltage; and outputting (106) an approved test result if the difference between said determined battery voltage and said predefined reference voltage falls within a predetermined range.

Description

technical field [0001] Embodiments herein relate to a method for performing a diagnostic test of an alternator of a vehicle. Embodiments herein also relate to a test arrangement for performing a diagnostic test of an alternator of a vehicle and a vehicle comprising such a test arrangement. Background technique [0002] Vehicles equipped with an internal combustion engine typically include an alternator and a battery. In operation, the internal combustion engine drives an alternator, and the alternator is arranged to charge the battery. Batteries can be used to power some power consumers such as spark plugs, headlights, climate control systems, entertainment systems, and external chargers. [0003] When a component of the alternator-battery-chain fails, the consumer may not receive enough power to function properly. For example, the alternator may not be able to charge the battery, the battery may not be able to store power in one or more cells long enough, and / or connecti...
