Abstract: The application relates to charging a maintenance battery pack of a vehicle, which also comprises a propulsion battery pack, comprising, when the vehicle is inactive: providing a predetermined threshold SOC/SOH1Threshold value when charging is activated and a predetermined threshold SOH2Threshold value when charging is terminated; continually measuring maintenance battery pack voltage, current, and temperature; calculating State Of Charge SOC, as number of ampere hours possible to discharge before the maintenance battery pack is discharged; calculating State of Health SOH, as number of ampere hours possible to discharge if the maintenance battery pack was fully charged; calculating a battery charge quota SOC/SOH; comparing SOC/SOH with the SOC/SOH1Threshold value; if SOC/SOH<SOC/SOH1Threshold, checking the condition of the propulsion battery pack, and if condition is satisfactory, activating the propulsion battery pack to charge the maintenance battery, comparing SOC/SOH with the SOC/SOH2Threshold value; a

Abstract: The present application relates to a power supply circuit of a vehicle, which power supply circuit comprises a first side (A) comprising a power source (14), a first battery pack (12) and first power consumers (16), a second side (B) connected in series with the first side (A), the second side (B) comprising a second battery pack (18) and second power consumers (20), an overload current breaker (22) provided between the first and the second side, said overload current breaker (22) having a pre-determined threshold breaking current (IThreshold) value, at which value the circuit is broken; a controller (24) connected to said power source for regulating voltage from said power source (14), the controller (24) being provided with said threshold breaking current (IThreshold) value, the controller further being operatively connected to devices (26, 28) providing information related to a current (Ich) through said overload current breaker (22).

Abstract: A method for determining the association of a sensor device with a battery unit. A first circuit includes a first battery unit. A second circuit includes a second battery unit. An electric current limiting device connects the circuits to one another. A first sensor device detects a voltage or a current associated with one of the first and second battery units while a second sensor device detects a voltage or a current associated with the other one of the first and second battery units. The method includes activating an electrical energy consumer or an electrical energy producer of the first circuit, and upon detection of a voltage change or a current change by one of the first and second sensor devices, determining that the one of the first and second sensor devices which detects a voltage change or a current change is associated with the first battery unit.

Abstract: An arrangement for preventing access to live parts in charging contact sockets of a hybrid or electrified vehicle having a plurality of such sockets each connectable to an external source of electric energy through a switch in an electric vehicle supply equipment station by inserting an electric plug in a socket for providing electric energy to batteries comprises blind plugs insertable into the sockets and the sockets are connected to each other and the batteries. A device is configured to sense presence of either an electric plug or a blind plug in each socket and the switch will be closed under the condition that either an electric plug or a blind plug is sensed by the device for all sockets and at least one of these plugs is an electric plug.

Abstract: An arrangement for controlling a disconnector arranged between power batteries and a consumer side of an electric system of a motor vehicle comprises a maneuver switch to be manually operated and configured to connect a control unit for the control of the disconnector to a conducting line on the battery side of the disconnector. The maneuver switch is configured to in a first position by movable contact members thereof connect each of two fixed output contacts to a different of two fixed input contacts than in a second position. A parameter is sensed on at least one input line from the maneuver switch to the control unit for determining which of the first and second position is assumed by the maneuver switch.
