Methods and systems for distributing electricity to multiple loads based on a scheduler and ammeter measurements

A method of charging a electric vehicle (EV) at a plurality of EV chargers, comprising:

• a. determining a total amount of current being drawn by the plurality of EV chargers at a first time period;
• b. authenticating a first user;
• c. when the total amount of current being drawn is below a first threshold, allowing a first EV charger to charge the first user's EV;
• d. authenticating a second user;
• e. when the total amount of current being drawn is below the first threshold, allowing a second EV charger to charge the second user' EV;
• f. when determined an estimated total amount of current to be drawn is above the first threshold:
• i. stopping the first EV charger to charge the first user's EV;
• ii. when the total amount of current being drawn is below the first threshold, allowing a second EV charger to charge the second user' EV;
• and
• wherein the plurality of EV chargers is capable of communicating with a remote server wirelessly.

A system of charging an electrical vehicle (EV) at a plurality of EV chargers, comprising:

• one or more network interfaces;
• one or more processing units;
• and
• one or more non-transitory computer readable storage mediums storing program instructions executable by the one or more processing units for:
• a. determining an estimated amount of current to be drawn by the plurality of EV chargers at a first time period;
• b. allowing a first user to reserve a first EV charger of the plurality of EV chargers at a remote reservation server if the estimated amount of current to be drawn is below a first threshold at the first time period;
• c. restricting the number of EV chargers to be reserved by users if the estimated amount of current to be drawn is above the first threshold at the first time period;
• d. during the first time period, after the first user is authenticated, charging the first user's EV via the first EV charger;
• and
• wherein each of the plurality of EV chargers is capable of communicating with the remote reservation server wirelessly.
