Abstract: Provided is a method of operating an electrical system including a first battery, a second battery coupled in series with the first battery, and a battery equalizer coupled to the first battery and the second battery and configured to supply an equalizing current to the first battery. The method includes monitoring a level of the equalizing current, determining, based on monitoring of the level of the equalizing current, that the equalizing current is saturated, and reducing a level of current supplied at a positive terminal of the first battery in response to determining that the equalizing current is saturated. The methods may take an action to reduce the demand for current that is supplied by the first battery.

Abstract: A vehicle power supply system (100), comprising: —a vehicle battery (111) with a charging voltage, —a DC-to-DC converter (130) comprising two first connection terminals (110) connected to the vehicle battery (111) and two second connection terminals (120) for connecting an external charger to recharge the vehicle battery (111) or for connecting an external battery to be recharged, wherein, in a first mode in which an external charger is connected to the two second connection terminals (120), the voltage V2 between the two second connection terminals (120) is an input voltage of the converter and the voltage V1 between the two first connection terminals (110) is an output voltage of the converter, wherein, in a second mode in which an external battery to be recharged is connected to the two second connection terminals (120), the voltage V1 between the two first connection terminals (110) is an input voltage of the converter and the voltage V2 between the two second connection terminals (120) is an output volta
