Mangaluru: Two electrical engineers from Mangaluru have developed and patented a groundbreaking fast-charging system for electric vehicles (EVs) and battery-powered devices. The system, which features internal recharging and a dual or multiple battery split-charging mechanism, promises to tackle major challenges in the EV sector such as long charging times, limited range, and dependence on external charging infrastructure.
The innovation was developed by Kishore Bhat M and Shashikumar R, who have named their invention “Electrically operated device with an internal battery refilling and split fast-charging system.” The patent-pending system aims to revolutionise electric mobility and power management by allowing continuous operation without the need for external charging.
Addressing EV limitations with internal recharging
Speaking about the concept, Bhat explained that the growing adoption of electric vehicles and battery-operated gadgets has highlighted the need for sustainable and efficient energy solutions. “The growing use of EVs and battery-powered devices is important to bring down pollution. However, at present, there are several challenges, including long charging times and limited charging infrastructure,” he said.
To address these issues, the engineers designed a self-sustaining internal recharging system that operates with two or more battery packs. While one battery powers the vehicle or device, the other charges internally using a built-in generation unit powered by biofuels or renewable sources such as solar or wind energy. Once the charging cycle is complete, the system automatically switches between the battery packs, ensuring uninterrupted operation.
Split fast-charging system for safety and speed
A key highlight of the patented technology is its split fast-charging mechanism, in which each battery pack is divided into smaller, manageable modules. This modular design enables balanced and rapid charging, significantly reducing overall charging time while minimising heat build-up — a common concern in traditional fast-charging systems.
“This split approach improves safety, enhances efficiency, and extends battery life,” Bhat said, adding that the design also allows for smart power distribution to ensure optimal energy usage.
The system, according to the developers, can be integrated into a wide range of battery-operated technologies beyond vehicles — including drones, industrial tools, and portable energy systems. The engineers believe it can drastically reduce range anxiety, a major concern for EV users, while simultaneously cutting down carbon emissions.
Potential to accelerate clean energy transition
The patented system also incorporates intelligent power management and renewable energy integration, making it a scalable solution for clean energy mobility. With its dual charging and internal generation capabilities, the innovation could drastically reduce dependence on external charging stations, particularly in remote or rural areas.
“The system combines renewable generation, intelligent power management, and modular fast charging into one integrated framework,” said Bhat. “It can help accelerate the global transition towards sustainable transportation and energy systems.”
Guiding young innovators through patents
Beyond his work as an innovator, Bhat is also authoring a comprehensive guidebook on the patent process. The book will outline each step involved in transforming an idea into a recognised patent — from concept development and documentation to submission and approval.
His aim, he said, is to help students, young innovators, researchers, and entrepreneurs better understand intellectual property rights and the importance of protecting original ideas. “There is immense talent in India, but many innovators do not know how to safeguard their creations. I want to bridge that gap,” Bhat explained.
Future outlook
With India’s electric vehicle market projected to cross ₹1 lakh crore by 2030, innovations like Bhat and Shashikumar’s system could play a key role in strengthening the nation’s EV ecosystem. Industry experts believe that such indigenous technologies can boost domestic manufacturing, lower costs, and make EVs more accessible to the public.
The engineers are currently exploring collaborations with research institutions and EV manufacturers to test large-scale applications of the system. They are also considering licensing opportunities to expand its reach across sectors.
If successfully commercialised, the Mangaluru-developed technology could set a new benchmark for self-sustaining, fast-charging electric mobility systems, helping India move closer to its clean energy goals.
