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.

Claims

1. A method for setting up an on-board charger in an electrically driven vehicle, comprising:

querying whether a proxy resistor of a charging socket of the vehicle is present,

carrying out a master configuration of the on-board charger if the proxy resistor is present; and

carrying out a slave configuration of the on-board charger if the proxy resistor is not present.

2. The method of claim 1, further comprising:

activating a programmable logic controller of the on-board charger if the master configuration is carried out; and

deactivating the programmable logic controller if the slave configuration is carried out.

3. The method of claim 2, further comprising:

using the on-board charger to configure a CAN matrix stored in the on-board charger during the master configuration or the slave configuration; and

using the on-board charger to configure a history memory of the on-board charger during the master configuration or the slave configuration.

4. The method of claim 3, further comprising:

transmitting a signal from the on-board charger via a CAN of the vehicle and waiting for a confirmation of the signal by a further on-board charger for a predefined period after the master configuration; and

using the on-board charger to configure itself for individual operation if the confirmation is absent over the period; and

making a diagnosis during individual operation.

5. The method of claim 4, further comprising:

using the further on-board charger to configure itself for paired operation if the further on-board charger receives the signal inside the period and transmitting the confirmation via the CAN; and

receiving the confirmation by the on-board charger and configuring the paired operation in the vehicle.

6. The method of in claim 5, further comprising:

using the on-board charger to adjust a charging power calculation to the paired operation after the on-board charger has configured the paired operation;

carrying out a parameterization for the paired operation; and

initiating a communication via the CAN and storing settings in the on-board chargers.

7. The method of claim 1, further comprising:

preparing the on-board charger to receive a signal via a CAN of the vehicle after the slave configuration; and

waiting for a predefined period.

8. An apparatus for carrying out the method of claim 1, comprising:

means for querying a proxy resistor of a charging socket of a vehicle;

means for the master configuration of an on-board charger of the vehicle if the proxy resistor is present; and

means for the slave configuration of the on-board charger if the proxy resistor is not present.

9. A computer program that is set up to carry out all steps of the method of claim 1.

10. A machine-readable storage medium having the computer program of claim 9 stored thereon.
