## Abstract

A method for providing charging resources to electric vehicles comprising a control system of an electric vehicle supply equipment, EVSE, storing a default charging profile. The default charging profile defines a first maximum amount of charging resources that the EVSE may provide to charging electric vehicle(s). The control system receiving from a central control system, via a communication connection, a charging profile that defines a second maximum amount of charging resources that the EVSE may provide to charging electric vehicle(s). The control system effectuates the received charging profile by causing the EVSE to provide at most the second maximum amount of charging resources to charging electric vehicle(s). The control system determining that the communication connection is broken and, based on this determination, effectuating the default charging profile causing the EVSE to provide at most the first maximum amount of charging resources to the charging electric vehicle(s).

## Claims

### Claim 1

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with the first EVSE, the first charging profile defining a first expiry time after which the first charging profile is no longer valid;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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the central control system determining that no new charging profile has been sent to the first control system of the first EVSE before the first charging profile expired is indicative of said communication connection between the first control system and the central control system being broken.

### Claim 3 (depends on 1)

The method of claim 1, wherein, at any given time, a sum of the respective maximum amounts does not exceed the capacity group maximum amount, and wherein each said respective maximum amount is larger than or equal to some minimum amount required to charge one said electric vehicle at least part of the time.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
the central control system determining a third charging profile, the third charging profile defining a third maximum amount of charging resources that the second EVSE may provide to said electric vehicle charging with the second EVSE, the third charging profile being different from the second charging profile, and either
the central control system sending the third charging profile to the second control system, after sending the first charging profile to the first control system and before determining that the first charging profile has expired, wherein the third charging profile is based on the first charging profile for the first EVSE and on the capacity group maximum amount; or
the central control system, before sending the first charging profile to the first control system, determining the first charging profile based on the third charging profile and on the capacity group maximum amount.

### Claim 5

A method for providing charging resources to an electric vehicle, the method comprising:
a control system of an electric-vehicle supply equipment, EVSE, storing a default charging profile, the default charging profile defining a default maximum amount of charging resources that the EVSE may provide to said electric vehicle during at least part of a time period defined by the default charging profile;
the control system of the EVSE receiving from a central control system, via a communication connection between the control system and the central control system, a first charging profile, the first charging profile defining a first maximum amount of charging resources that the EVSE may provide to said electric vehicle, the first charging profile defining a first expiry time after which the first charging profile is no longer valid;
the control system effectuating the first charging profile causing the EVSE to provide at most the first maximum amount of charging resources to said electric vehicle;
the control system determining that no new charging profile has been received before the first expiry time defined by the first charging profile; and
based on this determination, the control system effectuating the default charging profile causing the EVSE to provide at any given time at most the default maximum amount of charging resources as defined for that given time by the default charging profile to said electric vehicle.

### Claim 6 (depends on 5)

The method of claim 5, wherein said default maximum amount is larger than or equal to some minimum amount required to charge said electric vehicle at least part of the time.

### Claim 9 (depends on 5)

The method of claim 5, further comprising:
