Electric vehicle charging master controller

An electric vehicle charging master controller, comprising:

• an instruction processing unit configured to transmit information and receive information;
• a user interface module configured to receive information from the instruction processing unit and transmit information to the instruction processing unit;
• and
• a charging interface module configured to receive information from the instruction processing unit and transmit information to electric vehicle charging equipment that is external to the electric vehicle charging master controller;
• wherein:
• the instruction processing unit is configured to transmit a first set of information to the charging interface module designed to cause the electric vehicle charging equipment to direct a first charging current to a first electric vehicle of a plurality of electric vehicles coupled to the electric vehicle charging equipment;
• the instruction processing unit is configured to transmit a second set of information to the charging interface module designed to cause the electric vehicle charging equipment to stop the first charging current to the first electric vehicle when a first charging cessation criterion has been met;
• the instruction processing unit is configured to transmit a third set of information to the charging interface module designed to cause the electric vehicle charging equipment to direct a second charging current to a second electric vehicle of the plurality of electric vehicles;
• and
• the instruction processing unit is configured to transmit a fourth set of information to the charging interface module designed to cause the electric vehicle charging equipment to stop the second charging current to the second electric vehicle when a second charging cessation criterion has been met.
