MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631003910 A) filed by National Institute Of Technology, Rourkela, Orissa, on Jan. 14, for 'system and method for power management in dc microgrid with efficient electric vehicle charging.'
Inventor(s) include Varma, Mr. Katru Vikash; Pattnaik, Dr. Monalisa; and Sarkar, Dr. Indrajit.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a power electronic system (100) and method (300) for charging an electric vehicle (EV) battery (4) in a direct current microgrid (DCMG). The system (100) integrates a photovoltaic (PV) array unit (1) and a battery storage unit (2) as distributed power sources supplying a DC bus (3). A non-isolated bidirectional DC-DC converter regulates the DC bus voltage while balancing power between PV generation and load demand. A dual active bridge (DAB) converter unit (5) interfaces the DC bus with the EV battery (4) and operates using an extended phase shift (EPS) control scheme to provide efficient power transfer. The EPS control achieves constant current charging with substantially reduced backflow power compared to single phase shift operation, enhancing charging efficiency and microgrid stability under variable conditions. The present invention is applicable to renewable-integrated EV charging infrastructures and distributed DC microgrids."
