Control system for electric vehicle charging station and method thereof
First Claim
1. A control system for an electric vehicle charging station (EVCS) including a plurality of electric vehicle supply devices including a first electric vehicle supply device, the plurality of electric vehicle supply devices being structured to charge a plurality of electric vehicles, the control system comprising:
- a central controller configured to receive an ancillary service order from a power grid structured to request ancillary service during an ancillary service period, generate a plurality of coordinated ancillary service orders including a first coordinated ancillary service order, and distribute the plurality of coordinated ancillary service orders to a plurality of local controllers including a first local controller;
wherein the plurality of local controllers are each configured to control the plurality of electric vehicle supply devices in real time using the plurality of coordinated ancillary service orders so as to coordinate ancillary service to the power grid during the entire ancillary service period,wherein each coordinated ancillary service order includes an ancillary service providing time period and a battery charging time period, andwherein the ancillary service providing time period of the first coordinated ancillary service order includes a first time period during which the first local controller operates the first electric vehicle supply device so as to prepare for future ancillary service by regulating energy in a battery of an electric vehicle and a second time period during which the first local controller operates the first electric vehicle supply device so as to provide ancillary service following the first time period.

Abstract
A control system for an electric vehicle charging station (EVCS) is provided, the control system comprises: a central controller configured to receive an ancillary service order from a power grid and distribute the ancillary service order to one or more local controllers periodically; and the one or more local controllers configured to control a plurality of electric vehicle supply devices based on the distributed ancillary service order in real time. The method controlling the electric vehicle charging station (EVCS) is also provided.

17. A method for controlling an electric vehicle charging station (EVCS) including a plurality of electric vehicle supply devices each structured to charge an electric vehicle, comprising:
-
receiving an ancillary service order from a power grid structured to request ancillary service during an ancillary service period; generating a plurality of coordinated ancillary service orders using the received ancillary service order; distributing the plurality of coordinated ancillary service orders to a plurality of lower level controllers periodically; and controlling, in real time, a plurality of electric vehicle supply devices, with the plurality of lower level controllers, based on the plurality of coordinated ancillary service orders, so as to coordinate ancillary service during the entire ancillary service period; wherein each coordinated ancillary service order includes an ancillary service providing time period and battery charging time period; and wherein the ancillary service providing time period of one coordinated ancillary service order includes a first time period during which the lower level controller that received the one coordinated ancillary service order prepares for ancillary service by regulating energy in a battery of an electric vehicle and a second time period during which the lower level controller provides ancillary service. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
