Abstract: An energy aggregation system comprises a bus configured to receive power from one or more power sources and to deliver power to a grid connected to the bus; at least one energy storage system connected to the bus and configured either to draw power from the bus or discharge power to the bus; at least one electric vehicle charging stall connected to the bus and configured to deliver power, from an electric vehicle load connected to the at least one electric vehicle charging stall, to the bus; and at least one control module configured to monitor power on the bus and control delivery of power from the bus to the grid.

Abstract: An electric vehicle charging station comprises a direct current (DC) bus configured to receive DC power from multiple power sources including at least one battery energy storage system (BESS); at least one electric vehicle charging stall connected to the DC bus and configured to charge an electric vehicle load; and a controller configured to monitor and control power flow from the DC bus to the at least one electric vehicle charging stall and to monitor and control power flow between the BESS and the DC bus.

Abstract: An electric vehicle charging depot comprises a direct current (DC) bus configured to receive DC power from one or more power sources, the one or more power sources at least including a public transit light rail and/or subway power source; at least one electric vehicle charging stall connected to the DC bus and configured to charge an electric vehicle load; and at least one control module configured to monitor and control power flow from the DC bus to the at least one electric vehicle charging stall.
