Device for Charging and Discharging a Drive Energy Store of a Hybrid or Electric Vehicle, and System for Managing a Plurality of Hybrid or Electric Vehicles

A device for charging and discharging a drive energy store of a hybrid or electric vehicle, the device comprising:

• a frequency measurement module which is configured to measure a network frequency of an energy supply network;
• a control module which is configured to control, on the basis of the measured network frequency, charging of the drive energy store from the energy supply network or discharging of the drive energy store into the energy supply network in order to provide a regulating power;
• and
• a first communication module which is configured to communicate, as a master, with the hybrid or electric vehicle for providing the regulating power.

A system for managing a plurality of hybrid or electric vehicles which are configured to provide a regulating power for an energy supply network, the system comprising:

• a second communication module which is configured to receive, from a candidate vehicle of the plurality of hybrid or electric vehicles, state data relating to the candidate vehicle;
• and
• a computing module which is configured to determine, on the basis of the state data relating to the candidate vehicle, whether the candidate vehicle is intended to be permitted to provide the regulating power,
• wherein the second communication module is further configured to transmit a standby message to the candidate vehicle if it has been determined that the candidate vehicle is intended to be permitted to provide the regulating power, in order to change the candidate vehicle to a standby mode in which the candidate vehicle communicates, as a slave, with a charging station.

A method for charging and discharging a drive energy store of a hybrid or electric vehicle by via a charging station, the method comprising:

• using the charging station to measure a network frequency of an energy supply network;
• and
• using the charging station to control charging of the drive energy store from the energy supply network or discharging of the drive energy store into the energy supply network in order to provide a regulating power,
• wherein the charging station communicates, as a master, with the hybrid or electric vehicle.

A method for managing a plurality of hybrid or electric vehicles which are configured to provide a regulating power for an energy supply network, the method comprising:

• receiving state data from at least one candidate vehicle of the plurality of hybrid or electric vehicles in a backend;
• using the backend to determine whether the candidate vehicle is intended to be permitted to provide the regulating power on the basis of the state data relating to the candidate vehicle;
• and
• transmitting a standby message from the backend to the candidate vehicle if it has been determined that the candidate vehicle is intended to be permitted to provide the regulating power, in order to change the candidate vehicle to a standby mode in which the candidate vehicle communicates, as a slave, with a charging station.
