Hybrid Passive Cooling System Using Heat Pipes and Nano Fluid Delivers Pump-Free, Energy-Efficient Thermal Management for Next-Gen EV Battery Safety and Performance
In a significant breakthrough for India’s electric mobility ecosystem, researchers at MIT World Peace University (MIT-WPU) have developed a new patented hybrid cooling system designed to make electric vehicle (EV) batteries safer, cooler, and more efficient, especially under India’s harsh climatic conditions.
The innovation, granted a patent under the title “System for Thermal Management of Battery of Vehicle,” aims to address two of the biggest challenges facing EVs in India—high ambient temperatures and the recent increase in EV fire incidents. According to the institute, the system has been engineered to deliver improved thermal stability, enhanced battery performance, and significantly better operational safety.
At the heart of the solution is a hybrid passive cooling mechanism that combines high-efficiency heat pipes with a specially formulated nano fluid. Unlike traditional cooling systems, which rely on pumps or active mechanical components, this setup provides a pump-free, energy-efficient alternative, ensuring thermal regulation without drawing additional power from the battery.
“In a high-temperature environment like India, the challenge is not just achieving performance but ensuring safety first,” said Dr. Vaibhav Deshmukh, Associate Professor, Department of Mechanical Engineering, MIT-WPU.
“Our passive hybrid cooling system keeps the battery pack within safe thermal limits without consuming vehicle power, improving both reliability and efficiency.”
Echoing this, Dr. S. Radhakrishnan, Professor Emeritus and Director of Research, Department of Materials Science & Engineering, highlighted the innovation’s focus on long-term dependability.
“We wanted to eliminate active components that can fail or consume extra energy. The result is a robust solution built for high-temperature markets and growing fire-risk concerns,” he said.
The development comes at a crucial time as EV adoption accelerates across India, pushing manufacturers and researchers to strengthen vehicle safety standards and reliability measures.
