Accelerate your career in India’s booming energy storage and electric mobility ecosystem.
The Indian Institute of Solar Energy (IISE) provides industry-focused technical training covering
Lithium-ion cell technology, Battery Management System (BMS) design & testing,
battery pack assembly, and grid-scale Battery Energy Storage Systems (BESS).
Learn through authentic practical laboratory workshops at our Mumbai campus or flexible blended programs led by clean-energy practitioners.

The rapid decarbonization of India’s economy is powered by two complementary mega-trends: electric mobility (EVs)
and renewable energy grid integration. Behind both revolutions lies an urgent technical requirement:
safe, efficient, and robust battery systems.
Battery systems engineering is not merely about understanding basic electrochemistry. It is a multi-disciplinary engineering field combining
cell characterization, power electronics, embedded firmware (Battery Management Systems),
thermal management, and mechanical enclosure engineering to deliver reliable power under diverse operating conditions.
Low voltage (3.7V – 14.8V) modular configurations engineered for consumer electronics, power tools, and portable medical devices. Focuses on compact form factors, standard charge rates, and internal circuit protection.
High-voltage (48V, 60V, 72V in 2W/3W; 350V–800V in 4W & buses) traction packs subjected to high dynamic C-rates, vibration, regenerative braking, and strict AIS-156 safety compliance with active thermal protection.
Stationary megawatt-hour energy storage systems integrated with Solar PV and microgrids. Designed for multi-hour energy shifting, peak shaving, demand charge reduction, and grid stability with 4,000–6,000+ cycle life.
Why Battery Systems Courses Matter in India:
As India pushes toward 500 GW of non-fossil capacity by 2030 and accelerates EV adoption under FAME and state EV policies,
industry demand has shifted from theoretical degree-holders to engineers and technicians who understand
cell grading, BMS programming, spot welding, wiring harness fabrication, and AIS-156 testing protocols.
Whether you are a fresh engineering graduate, a solar EPC professional adding storage, or an entrepreneur planning a battery pack assembly unit,
IISE provides clear educational pathways aligned with industry reality.

In our programs, students learn how to evaluate and select the right chemistry for electric mobility and grid-connected storage.
