An electrical power converter unit () includes: a first connection interface () comprising two leads () forming a DC input/output interface for connecting a first electrical device to the power converter unit, a three-phase rectifier power converter circuit () and a second connection interface () for connecting a second electrical device to the power converter unit. The second connection interface includes a switching unit () adapted to switch between:&#x2014;a DC input/output mode, in which first, second and third arms of the power converter circuit () are electrically connected together, forming one DC input/output; and&#x2014;an AC input/output mode, in which the arms are disconnected from each other, forming separate input/outputs for a three-phase AC voltage.

A vehicle includes an air compressor system for supplying compressed air to an air consuming circuit, wherein the vehicle includes an arrangement for determining that the vehicle is coasting. The compressor system is controllable to deliver compressed air at a first power rate and at least at a second higher power rate, and it is controlled to deliver compressed air at the second higher power rate when it is determined that the vehicle is coasting. A method for operating an air compressor system for such a vehicle is also provided.

A method is provided for controlling a power supply system of an automotive vehicle that includes at least one battery and at least one associated battery managing unit adapted to monitor the state of charge of the battery. During an off state of the vehicle, the state of charge level of each battery is monitored by the battery managing unit. If the state of charge monitored reaches a low state of charge threshold, an on-board communication device adapted to emit a critical state of charge level alarm to be received by an off-board reception device is activated. The power supply system includes a battery managing unit per battery and an alarm to emit a critical state of charge level alarm.
