Claim 10:
11. A method for network-based energy management of electric vehicle (EV) charging network infrastructure, the method comprising:
providing a gateway including one or more of an electric vehicle supply equipment (EVSE), a building automation system and an additional independent gateway controller,
wherein the gateway is configured to access all EVSEs in a local network and gather status as well as send commands individually,
wherein the gateway is configured for performing charging authorization, load management and/or demand response on an EVSE network using more than one communication channels including remote and/or local modes,
wherein the EVSE network includes two or more components from a group of components including a first EVSE, a controller, a second EVSE, the building automation system, a local server, a remote server and other energy management device,
wherein the first EVSE selects a command from one or more remote or local commands, and further issues commands to one or more EVSEs in a network such that the network is modelled using a parent—child structure/configuration in that a regular sync-up can be done from a server to send load balancing profiles to a parent unit that can be converted to local commands for child units,
wherein a parent EVSE acts as a network access point to a child EVSE as the parent EVSE is connected to the child EVSE via a network connection on a paired wireless network, a personal area wireless ad hoc network or a client-server wired network, and
wherein the parent EVSE can process multiple energy management commands received to derive a charging profile and also act as a pass through medium to the child EVSE through its network connection.
