Managing and optimizing energy supply from grid and renewable source with electric vehicle supply equipment

An electrical supply system for an electric vehicle (EV), the system comprising:

• an electric vehicle supply equipment (EVSE) charging station including a meter, a switch, a controller and a wireless communication unit, the EVSE charging station configured to couple to the EV for electrically charging a battery of the EV, the wireless communication unit is configured to communicate with a wireless communication device that is configured to communicate with a EVSE server and a utility server, the EVSE server is configured to communicate with a user communication device,
• wherein the meter is operable to receive charging information from one or more sources and provide metering information of a first power source and a second power source by measuring values of at least one of charge current and charge voltage and calculate one or more energy usage parameters including charge power usage or charge energy usage from the measured values of charge current and/or charge voltage,
• wherein the switch is configured to couple to the first power source and the second power source, the first power source to receive energy from a renewable power source to charge the battery of the EV and the second power source to receive energy from a power grid to charge the battery of the EV, the switch is operable to switch between the first power source and the second power source,
• wherein the controller is configured to control the switch by switching between the first power source and the second power source based on a time of use or real-time energy pricing data from a utility and based on the charging information from one or more sources and the metering information associated with the first power source and the second power source,
• wherein the second power source is used during selected hours and periods when the first power source is unavailable,
• wherein the time of use or real-time energy pricing data is a set peak demand limit for a load center,
• wherein the set peak demand limit is established by a do not exceed energy demand limit value to keep the energy demand of the load center and the EV at or below the set peak demand limit,
• wherein the EVSE charging station is configured to monitor and measure power used by the EV from the first power source and power used by the EV from the second power source,
• wherein the EVSE charging station is configured to control a flow of renewable power between the power grid, the EV and any loads on the load center, and
• wherein the EVSE charging station is configured to communicate real time data corresponding to power source selection of the EVSE charging station to other smart devices coupled to the load center or other loads capable of receiving communication wirelessly for allowing lowering or increasing a power consumed by the smart devices and other loads.
