Claim 9:
10. A method of charging an electric vehicle (EV) at a plurality of EV chargers, comprising:
a. determining a total amount of current being drawn by all EV chargers in the plurality of EV chargers;
b. determining if a first EV charger is available in the plurality of EV chargers:
i. if the first EV charger is available in the plurality of EV chargers, authenticating a first user; and
ii. if no EV charger is available in the plurality of EV chargers, allowing the first user to reserve a first time slot at a remote server;

c. when the total amount of current being drawn is below a threshold and the first user is authenticated, enabling a relay of a first EV charger to commence charging process of a first EV of the first user;
d. determining if a second EV charger is available in the plurality of EV chargers:
i. if the second EV charger is available in the plurality of EV chargers, authenticating a second user; and
ii. if no EV charger is available in the plurality of EV chargers, allowing the second user to reserve a second time slot at the remote server;

e. when the total amount of current being drawn is below the threshold and the second user is authenticated, enabling a relay of a second EV charger to commence charging process of a second EV of the second user; and
f. when the total amount of current to be drawn is above the threshold:
i. disabling the relay of the first EV charger to stop the charging process of the first EV; and
ii. disabling the relay of the second EV charger to stop the charging process of the second EV;

wherein the plurality of EV chargers are configured to communicate with the remote server.
