1. A system for controlling a plurality of chargers for electric vehicles, the system comprising:
a first server comprising an Open Charge Point Protocol (OCPP) server, said server being for communicating with said plurality of chargers using a first communications protocol, said first server also being for communicating with a controller component using a second communications protocol;
a second server comprising a MODBUS TCP/IP server, said second server being for communicating with a controller server using a third communications protocol, said controller server being for controlling a plurality of industrial equipment using a fourth communications protocol; and
a conversion module comprising a programmable logic controller (PLC), said conversion module being for converting communications between said third communications protocol and said fourth communications protocol, said conversion module being coupled to a piece of industrial equipment;
said piece of industrial equipment receiving control commands from said controller server using said fourth communications protocol;
wherein said first communications protocol is for controlling said plurality of chargers;
said second communications protocol is for communicating with web-enabled clients;
said controller component communicates with said controller server using said fourth communications protocol and said controller component is for controlling said plurality of industrial equipment through said controller server; and
said first server and said second server communicate with each other to pass commands and data between one another to thereby pass said commands and data to and from said plurality of chargers;
wherein said first communications protocol is an Open Charge Point Protocol (OCPP) communications and control protocol;
wherein said third communications protocol is a MODBUS TCP/IP communications and control protocol;
wherein said fourth communications protocol is an Open Platform Communications (OPC) communications and control protocol.
