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. ## Claims ### Claim 1 A non-transitory computer-readable storage medium including one or
