Abstract

A method for charging a plurality of motor vehicles, in particular hybrid electric/electric vehicles, at a plurality of public charging stations, having the steps of: determining release times at which the respective charging stations are released for charging; determining arrival times at which the respective motor vehicles can arrive at the respective charging stations; calculating intervals of time between the respective determined release times and the respective determined arrival times as required waiting times for charging the respective motor vehicles at the respective charging stations; deciding, on the basis of the calculated waiting times, which of the charging stations will be approached by the respective motor vehicles for charging, with the proviso that an actual total waiting time, which forms a sum of actual waiting times for charging the respective motor vehicles at the respective charging stations, is minimized.

Claims

1. A method for charging a plurality of motor vehicles, at a plurality of public charging stations comprising:

determining release times at which the respective charging stations are released for charging;

determining arrival times at which the respective motor vehicles can arrive at the respective charging stations;

calculating intervals of time between the respective determined release times and the respective determined arrival times as required waiting times for charging the respective motor vehicles at the respective charging stations; and

deciding, on the basis of the calculated waiting times, which of the charging stations will be approached by the respective motor vehicles for charging, with the proviso that an actual total waiting time, which forms a sum of actual waiting times for charging the respective motor vehicles at the respective charging stations, is minimized.

2. The method as claimed in claim 1, further comprising:

determining energy requirements of the respective motor vehicles for approaching the respective charging stations; and

comparing the determined energy requirements with one another;

wherein the deciding step also provides for a decision to be made, on the basis of the comparison result between the determined energy requirements, as regards which of the charging stations will be approached by the respective motor vehicles for charging.

3. The method as claimed in claim 1, further comprising:

determining ranges of the respective motor vehicles;

wherein the deciding step also provides for a decision to be made, on the basis of the determined ranges, as regards which of the charging stations will be approached by the respective motor vehicles for charging.

4. The method as claimed in claim 1, further comprising:

determining possible driving routes to destinations which have to be approached by the respective motor vehicles;

wherein the deciding step also provides for a decision to be made, on the basis of the determined driving routes, as regards which of the charging stations will be approached by the respective motor vehicles for charging.

6. The method as claimed in claim 2, further comprising:

determining ranges of the respective motor vehicles;

wherein the deciding step also provides for a decision to be made, on the basis of the determined ranges, as regards which of the charging stations will be approached by the respective motor vehicles for charging.

7. The method as claimed in claim 1, wherein the motor vehicles are hybrid electric/electric vehicles.

5. A system for charging a plurality of motor vehicles, at a plurality of public charging stations, comprising:

at least one first determination arrangement for determining release times at which the respective charging stations are released for charging;

at least one second determination arrangement for determining arrival times at which the respective motor vehicles can arrive at the respective charging stations;

at least one calculation arrangement for calculating intervals of time between the respective determined release times and the respective determined arrival times as required waiting times for charging the respective motor vehicles at the respective charging stations; and

a decision-making arrangement for deciding, on the basis of the calculated waiting times, which of the charging stations will be approached by the respective motor vehicles for charging.

8. The system as claimed in claim 5, wherein the motor vehicles are hybrid electric/electric vehicles.
