Methods and systems for allocating charging resources to electric vehicles

A method for allocating charging resources to a plurality of electric vehicles, comprising:

• a central control system storing a respective default charging profile for each of a plurality of electric-vehicle supply equipment, EVSEs, in a capacity group, the capacity group being associated with a capacity group maximum amount of charging resources, the capacity group maximum amount defining a maximum amount of charging resources that can be provided to the capacity group, wherein each respective default charging profile defines a respective maximum amount of charging resources that a respective said EVSE may provide to the electric vehicle charging with the respective EVSE;
• the central control system sending a first charging profile to a first control system of a first said EVSE of the plurality of EVSEs, via a communication connection between the central control system and the first control system, the first charging profile defining a first maximum amount of charging resources that the first EVSE may provide to one said electric vehicle charging with the first EVSE, the first charging profile defining a first expiry time after which the first charging profile is no longer valid;
• the central control system determining that the first charging profile has expired and that no new charging profile has been sent to the first control system of the first EVSE before the first charging profile expired;
• and
• based on this determination, the central control system determining a second charging profile defining a second maximum amount of charging resources that a second said EVSE in the capacity group may provide to one said electric vehicle charging with the second EVSE, the second maximum amount being based on the default charging profile stored for the first EVSE and the capacity group maximum amount, and sending the second charging profile to a second control system of the second EVSE.
