Visakhapatnam: Keeping pace with the global endeavour for developing sub-systems for electrical vehicles, Technorama, a startup of the electrical engineering department in Andhra University, is driving innovation across a spectrum of applications. Its commitment to in-house development and indigenisation of electrical and electronic subsystems is setting benchmarks for self-sustainability, affordability and reliability.

One of the flagship achievements of the team is the design of an exceptionally efficient 350 kW propulsion motor with permanent magnet technology, along with the accompanying electronic power drive, whose efficiency exceeds 95 per cent. This motor, developed for high-performance applications, exemplifies the team's focus on energy efficiency and durability.

Complementing this innovation, the team has designed a chassis tailored for high-capacity commercial transport applications. This motor design technology can be adopted to develop systems ranging from low-power solutions of 100 watts to robust electric engines with outputs of up to 1,000 kilowatts.

Furthermore, the Technorama team has developed an artificial intelligence-based digital twin model for lithium-ion batteries to work hand in hand with the existing BMS technology. This ground-breaking innovation offers real-time monitoring and predictive analytics, effectively mitigating safety risks. By enhancing battery management and performance, the digital twin model ensures a safer and more reliable experience for electric vehicle users.

Dr. Neelakanta, Head, Innovation – Technorama told Deccan Chronicle on Wednesday that India’s electric vehicle market is witnessing exponential growth, with projections indicating market size that could reach USD 47 billion by 2026, growing at a compound annual growth rate (CAGR) of 44 per cent. However, a significant portion of EV subsystems, including propulsion motors, power electronics and battery management systems, are currently imported. This dependency increases costs and limits serviceability, underscoring the need for indigenous solutions.

The import value of EV subsystems in India alone exceeds USD 5 billion annually, highlighting a critical gap in domestic manufacturing capabilities. By focusing on in-house development, Technorama aims to address this challenge, reducing reliance on imports and fostering a self-reliant ecosystem.

The indigenisation of EV systems is vital for ensuring self-sustainability, affordability and availability. Localised manufacturing not only reduces costs but also creates opportunities for skill development and employment. Moreover, indigenous systems are tailored to meet the specific needs of Indian conditions, enhancing their serviceability and reliability.

Dr. Rajesh, Head – Electric Propulsion, said Technorama’s holistic approach to developing EV subsystems—from vehicle control units to power electronics and digital twins—is a testament to its commitment for indigenisation. By prioritising in-house development, the company is fostering innovation and contributing to a robust and self-sufficient EV ecosystem in India.

As per Dr. Gautam, Head of Power Electronics, as demand is growing for efficient electric vehicle charging infrastructure, Technorama has engineered a high-power, modular, scalable and adaptive dual-gun DC fast-charging system..

Prof. Mallikarjuna Rao Pasumarathi of electrical engineering department and dean of trans-disciplinary research, who is the mentor for Technorama, said the company’s dedication to research, development and indigenisation underscores its mission to drive the transition towards a sustainable and self-reliant electric vehicle industry in India and beyond.
