Has anyone implemented smart EVSE solutions to optimize home charging schedules relative to dynamic time-of-use electricity rates? I am particularly interested in open-source or standards-based systems (e.g., OCPP, ISO 15118) that integrate with utility demand response programs and provide vehicle-to-grid (V2G) capability.
What are the current technical challenges in achieving reliable load shifting and grid interaction using commercially available smart EVSEs, especially regarding interoperability between chargers, vehicles, and home energy management systems? Additionally, what security and data privacy considerations should be prioritized when deploying such systems in residential settings?
