1. A method for configuring on-board chargers in an electrically-driven vehicle, the method comprising the steps of:
- querying a proxy resistor of a charging socket of the vehicle to determine if the presence of the proxy resistor is detectable with respect to a first on-board chargers, the proxy resistor adapted for use to detect when a charging plug is attached to the charging socket of the vehicle for enabling electrical power to be delivered to the vehicle;
querying the proxy resistor to determine if the presence of the proxy resistor is detectable with respect to a second on-board charger, wherein the proxy resistor is configured such that the presence of the proxy resistor is detectable by one of the first on-board charger or the second on-board charger;
configuring the first on-board charger as a master on-board charger if the presence of the proxy resistor is detectable with respect to the first on-board charger; and
configuring the second on-board charger as a slave on-board charger if the presence of the proxy resistor is not detectable with respect to the second on-board charger.

Abstract
A method is provided for setting up an on-board charger in an electrically driven vehicle with the following features: a proxy resistor of a charging socket of the vehicle is queried (44, 68); if the proxy resistor is present (46), a master configuration (48, 50, 52) of the on-board charger is carried out; and if the proxy resistor is not present (70), a slave configuration (72, 74, 76) of the on-board charger is carried out.

10. An apparatus for configuring on-board chargers in an electrically-driven vehicle, the apparatus comprising:
-
means for querying a proxy resistor of a charging socket of the vehicle to determine if the presence of the proxy resistor is detectable with respect to a first on-board chargers, the proxy resistor adapted for use to detect when a charging plug is attached to the charging socket of the vehicle for enabling electrical power to be transferred from the charging plug to the charging socket; means for querying the proxy resistor to determine if the presence of the proxy resistor is detectable with respect to a second on-board charger, wherein the proxy resistor is configured such that the presence of the proxy resistor is detectable by one of the first on-bard charger or the second on-board charger; means for configuring the first on-board charger as a master on-board charger if the proxy resistor is detectable with respect to the first on-board charger; and means for configuring the second on-board charger as a slave on-board charger if the proxy resistor is not detectable with respect to the second on-board charger. - View Dependent Claims (11, 12)

13. A non-transitory machine-readable storage medium having a computer program for configuring on-board chargers in an electrically-driven vehicle, the storage medium comprising logic for:
-
querying a proxy resistor of a charging socket of the vehicle to determine if the presence of the proxy resistor is detectable with respect to a first on-board chargers, the proxy resistor adapted for use to detect when an external charging plug is attached to the charging socket of the vehicle to allow electrical power to be delivered to the vehicle; querying the proxy resistor to determine if the presence of the proxy resistor is detectable with respect to a second on-board charger, wherein the proxy resistor is configured such that the presence of the proxy resistor is detectable by one of the first on-board charger or the second on-board charger; configuring the first on-board charger as a master on-board charger if the proxy resistor is detectable with respect to the first on-board charger; and configuring the second on-board charger as a slave on-board charger if the proxy resistor is not detectable with respect to the second on-board charger. - View Dependent Claims (14, 15, 16, 17, 18, 19)
