EV charging communication network with redundancy protocol and associated methods
An Electrical Vehicle (EV) charging station and communication network with redundancy protocol including a network server, a plurality of gateways with at least a first and second gateway, and a plurality of EV charging stations structured to be in WiFi communication with the plurality of gateways. First gateway, by default is the primary gateway and structured to be in cellular communication with the network server via first cellular communication provider. Second gateway by default is available as a charger, but in standby and structured to be in cellular communication with the network server via second cellular communication provider. The plurality of EV charging stations is structured to send and receive charging information via WiFi first gateway when it is the active primary gateway. They are structured to switch to second gateway when it has become the primary gateway due to communication failure of the first gateway with the network server.
1 . An EV charging station and communication network with redundancy protocol comprising
a network server;
a plurality of gateways including at least a first gateway and a second gateway;
a plurality of Electrical Vehicle (EV) charging stations configured to be in WiFi communication with the plurality of gateways;
wherein the first gateway is configured to be in cellular communication with a first cellular communication provider;
wherein the second gateway is configured to be in cellular communication with a second cellular communication provider that is different from the first cellular communication provider;
wherein the plurality of EV charging stations is configured to send and receive EV charging information via WiFi communication to the first gateway, defined as the primary gateway, which is active by default;
wherein the first gateway is configured to send and receive the EV charging station information to the network server via the first cellular communication provider by default;
wherein the plurality of EV charging stations is configured to send and receive information via WiFi communication to the second gateway when the plurality of EV charging stations has determined that communication has failed with the network server via the first gateway;
wherein the second gateway is configured to switch from dormant to active to become the primary gateway for communication with the network server via the second cellular communication provider when communication with the network server has failed via the first gateway.
