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

A system for scheduling electricity supply at a time scheduler to a plurality of electric vehicle (EV) chargers, comprising:

• a network interface;
• a processing unit coupled to the network interface;
• a non-transitory computer readable storage medium coupled to the processing unit and storing program instructions configured to cause the processing unit to perform the steps of:
• a. authenticating a user through an authentication server;
• b. when there is not enough electricity capacity to allow all EV chargers in the plurality of EV chargers to charge a plurality of electric vehicles simultaneously, determining whether to allow an EV charger in the plurality of EV chargers to be a scheduled EV charger for charging an EV associated with the user based on an amount of electricity available to all EV charges in the plurality of EV chargers;
• and
• c. when the user is authenticated and there is enough electricity capacity to allow the EV charger to charge the EV of the user:
• i. determining a location of the EV charger and making a reservation of the first EV charger for the user;
• ii. informing the user of the location of the EV charger;
• iii. when charging has not commenced at the EV charger within a first time limit, sending an alert to the user;
• iv. after the sending the alert to the user, when the charging has still not commenced at the EV charger within a second time limit, canceling the reservation;
• v. when the charging has commenced and is about to be completed, sending an about-completion-message to the user;
• and
• vi. reporting an amount of electricity used after completion;
• wherein:
• the EV charger is coupled to the relay;
• and
• when the relay is disabled, the EV charger is not capable of charging the EV associated with the user.
