Hi, I'm
Sai Chaitanya.
Battery Systems Engineer
I've spent 3+ years inside commercial EV development — designing packs, writing BMS logic, and navigating homologation. VoltPulse is where I put what I've actually learned into writing.
✓From cell to system — immersion cooling to swappable packs
✓Standards-aware, not standards-obsessed
✓Written from the bench, not the boardroom

WHY VOLTPULSE
What makes this different
First Principles
Every analysis starts from cell chemistry and physics — not marketing claims.
Real-World Data
Bench testing, thermal imaging, and on-road benchmarks — not just theory.
Production Reality
Writing from pack design and manufacturing — not research papers.
