Abstract

Systems and methods for establishing mesh connectivity among electric vehicle (EV) chargers within a network, leveraging Sub-GHz networking for enhanced communication. The method involves configuring a mesh network architecture connecting existing EV charging units, a host application, and a user application. Load balancing mechanisms consider the building's power usage beyond EV charging units, ensuring efficient energy distribution in real-time. Power allocation to EV chargers is dynamically adjusted based on load balancing metrics. The mesh network is seamlessly integrated with an internet backbone, facilitating communication with user devices such as smartphones and vehicles. This enables efficient communication between charging stations and a hosting application, allowing real-time monitoring and management of the charging network's power supply. The user application offers remote monitoring, scheduling of charging sessions, and billing functionalities, enhancing user experience and system efficiency. Some example embodiments include programs to connect the user application, host application, and mesh network.

A non-transitory computer-readable storage medium including one or more programs of a host application on a server configured to be executed by one or more processors, the one or more programs configured for use with an internet backbone and a user device, the one or more programs configured for communicating with electric vehicle (EV) charging units, a user application, and a management system for a facility containing the EV charging units, the one or more programs including instructions for:

executing, by the server, instructions that cause the server to communicate with the EV charging units within the facility using a mesh network, the communications comprising transmitting and receiving control and status data between the server and the EV charging units via the mesh network;
executing, by the server, instructions that cause the mesh network to communicate among the EV charging units utilizing Sub-GHz networking, the Sub-GHz networking comprising a Wi-SUN™ radio frequency protocol, the mesh network having a mesh network architecture that is connected to the internet backbone and that communicates with the user device;
and
executing, by the server, instructions that cause the host application to remotely monitor and manage the EV charging units, including dynamically adjusting network parameters of the mesh network or charging parameters based on received control and status data, and to display in real-time in the host application a total power supply available to the EV charging units;
and
performing, by the server, load balancing using actual element data from at least one electrical element using facility power, the at least one electrical element being different than the EV charging units,
wherein the load balancing uses actual load data from the EV charging units in real-time, and wherein the load balancing is used to control at least one variable frequency drive (VFD), wherein the VFD connects to at least one heat pump in a heating, ventilation, and air conditioning (HVAC) system.
