## Abstract

A method for operating a battery charging assistance system external to a motor vehicle involves the motor vehicle transmitting a charging request and an actual position of the motor vehicle to the battery charging assistance system. Depending on the position and the charging request, the battery charging assistance system chooses one battery charging station and the one battery charging station is reserved from the battery charging assistance system by transmitting a reservation signal to the one battery charging station. If the one battery charging station is occupied by a further electrical operated motor vehicle, a leaving message is computed and transmitted to the further motor vehicle in order to ask the further motor vehicle to leave the one battery charging station and if the further motor vehicle is leaving a compensation action for the further motor vehicle is initiated.

## Claims

### Claim 1

A method for operating a battery charging assistance system external to an at least partially electrically operated motor vehicle, the method comprising:
monitoring, by an electronic computing device of the at least partially electrically operated motor vehicle, a state of charge of a battery of the at least partially electrically operated motor vehicle;
transmitting, by the at least partially electrically operated motor vehicle and depending on the monitored state of charge of the battery of the at least partially electrically operated motor vehicle, a charging request to the battery charging assistance system, wherein the charging request is transmitted when a predefined state of charge threshold of the state of charge of the battery is reached and monitored by the electronic computing device, wherein the predefined state of charge threshold is a value corresponding to a critical state of charge of the battery;
receiving, by battery charging assistance system from the at least partially electrically operated motor vehicle via a first communication network, the charging request and an actual position of the at least partially electrically operated motor vehicle;
determining, by the battery charging assistance system, that a battery charging station at the actual position of the at least partially electrically operated motor vehicle is occupied;
identifying, by the battery charging assistance system, a plurality of battery charging stations at a different position than the actual position and that the at least partially electrically operated motor vehicle can reach with the state of charge of the battery;
choosing, by the battery charging assistance system, one battery charging station out of the plurality of battery charging stations at a location different than the actual position, depending on the actual position and the charging request;
reserving, by the battery charging assistance system, the chosen one battery charging station for a future time corresponding to a time for the at least partially electrically operated motor vehicle to reach the chosen at least one charging station, by transmitting a reservation signal to the one battery charging station via a second communication network;
if the chosen one battery charging station is occupied by an other at least partially electrically operated motor vehicle, a leaving message is computed from the one battery charging station or the battery charging assistance system and the leaving message is transmitted to the other at least partially electrically operated motor vehicle in order to ask the other at least partially electrically operated motor vehicle to leave the chosen one battery charging station; and
initiating, by the battery charging assistance system, a compensation action for the other at least partially electrically operated motor vehicle if the other at least partially electrically operated motor vehicle is leaving the chosen one battery charging station
wherein a connection sensor of at least the chosen one battery charging station detects a connection or a disconnection of the other motor vehicle at the chosen one battery charging station,
wherein a connection status of the chosen one battery charging station is transmitted to the battery charging assistance system, and
wherein, depending on the connection status, the compensation action is initiated for the other at least partially electrically operated motor vehicle.

### Claim 2 (depends on 1)

The method of claim 1, wherein an actual route of the at least partially electrically operated motor vehicle, which is provided by a navigation device of the at least partially electrically operated motor vehicle, is taken into consideration by choosing the one battery charging station out of the plurality of battery charging stations by the battery charging assistance system.

### Claim 3 (depends on 1)

The method of claim 1, wherein the compensation action
covers a payment for the other at least partially electrically operated motor vehicle,
is a cheaper charging fee for a current charging or a future charging for the other at least partially electrically operated motor vehicle, or
is a discount on a system for the battery charging assistance system for the other at least partially electrically operated motor vehicle.

### Claim 4 (depends on 1)

The method of claim 1, wherein, after the leaving message is transmitted to the other at least partially electrically operated motor vehicle, a user of the other at least partially electrically operated motor vehicle is asked to confirm the leaving and the confirmation is transmitted to the battery charging assistance system.

### Claim 5 (depends on 1)

The method of claim 1, wherein a reservation confirmation is transmitted to the at least partially electrically operated motor vehicle after a reservation of the chosen one battery charging station.
