Sequential Charging of Multiple Electric Vehicles
First Claim
1. An apparatus for sequential charging a plurality of electric vehicles, comprising:
- a socket connector configured to couple with an electrical socket;
a first power conduit having a first end connected to the socket connector and a plurality of distal ends, the first power conduit configured to convey a voltage from the electrical socket to the plurality of electric vehicles;
a first relay placed inline with the first power conduit and configured to control the voltage along the first power conduit;
a control circuit connected to the first power conduit and configured to generate signals corresponding to the voltage along the first power conduit;
a plurality of vehicle connectors each connected to a respective one of the plurality of distal ends of the first power conduit and configured to connect to a respective one of the plurality of electric vehicles; and
a second relay placed inline with the first power conduit and configured to control the voltage to the vehicle connectors to sequentially charge the plurality of electric vehicles.

Abstract
An apparatus and method for sequentially charging multiple electric vehicles. The apparatus including an electric vehicle supply equipment (EVSE) having an electrical plug connected to a power cord. The power cord is connected to a housing containing a number of electrical components configured to control the power flow to an electric vehicles to recharge the vehicles'"'"' batteries. The power cord is divided into multiple power cords that extend from the housing and connect to standard electric vehicle connectors compatible with battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV). The EVSE determines, based on a number of possible criteria, which of the multiple electric vehicles to charge at a given time.

16. A method for sequential charging of multiple electric vehicles, comprising:
-
detecting if multiple vehicles are connected to an electric vehicle supply equipment (EVSE); determining a priority for providing charging power to a battery of a first or a second electric vehicle of the multiple electric vehicles via a processor based on information received from the first and second electric vehicles or from a user input via an input device; providing charging power to the battery of the first or second electric vehicle via a respective vehicle connector based on the priority determination by the processor; monitoring the charge level of the battery of the first or second electric vehicle via the processor; determining, via the processor, whether to discontinue charging the battery of the first priority electric vehicle being charged; and determining whether to provide charging power to the battery of the second priority electric vehicle of the multiple electric vehicles via the processor. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
