A capacitor module for a vehicle, wherein the module includes a capacitor having a plurality of capacitor cells operatively connected to each other, a first port for being connected to a power supply arrangement, a second port for being connected to an electric machine for cranking an internal combustion engine, and a third port for being connected to ground. The capacitor module includes a first electrical device connected between the first port and the capacitor and that the first electrical device is adapted for allowing a current to flow out from the capacitor module via the first port for providing power to at least one load during operation in case of a sudden voltage drop in the power supply from the power supply arrangement.

A method for determining a status of a vehicle battery includes determining an initial temperature and an initial state of charge of the battery, determining a current threshold value based on the initial temperature and the initial state of charge of the battery, starting the vehicle engine, charging the battery for a predetermined charging period t, measuring two charging currents, Iand I, to the battery at two predetermined points in time during the charging period t, determining an expected current value at a time t=t+tbased on the measured charging currents, comparing the expected current value with the current threshold value, and determining the battery is faulty if the expected current value is lower than the current threshold value.
