What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12584647B2 for a novel method and system for the joint control of electric vehicle (EV) and building heating, ventilation, and air conditioning (HVAC) systems. The patent, assigned to TATA CONSULTANCY SERVICES LIMITED, addresses limitations in current energy management approaches for multi-input, multi-output systems like EV-HVAC. It proposes a scalable solution that leverages EVs as energy buffers, respecting both HVAC thermal constraints and EV state of charge (SoC) requirements.

This patent grant is primarily informational and does not impose new regulatory obligations on regulated entities. However, companies involved in smart grid technology, building energy management, EV charging infrastructure, and HVAC system development may find the patented technology relevant for future product integration or licensing considerations. The filing date for this patent was May 9, 2024, with the grant date of March 24, 2026.

Abstract

Current approaches for minimizing energy requirement of buildings are not designed to handle multi-input multi-output systems, such as electric vehicle-heating, ventilation, and air conditioning (EV-HVAC) system. Further, scalability of the solutions is another challenge. Present disclosure provides method and system for jointly controlling EV-HVAC system of a building. The system utilizes the potential of electric vehicle (EVs) in building energy management by treating EVs as buffers with random availability. The system performs EV-HVAC joint control that scales seamlessly with increasing EVs while respecting both thermal constraints of HVAC and state of charge (SoC) constraints of EV users.
