TESAS brings together 22+ years of combined engineering expertise in BMS, power electronics, and EV infrastructure. Founded in 2026 by a team with deep industry roots — delivering BESS, EV Charging, BMS Design, and AI-driven energy solutions across India.
End-to-end energy engineering — from system design and simulation to procurement, installation, and AI-driven optimisation.
Grid-scale, commercial, and industrial BESS design — from cell chemistry selection and system sizing to integration with solar, wind, and grid. We handle thermal management, safety, and compliance.
End-to-end EV charging network design for highways, commercial complexes, fleet depots, and residential societies. Level 2 AC and DC fast charging with smart load management.
Custom BMS hardware and firmware development — SOC/SOH estimation, cell balancing, fault protection, and CAN/Modbus communication for EV, ESS, and industrial battery packs.
Machine learning models for predictive maintenance, demand forecasting, optimal charge–discharge scheduling, and digital twins. Turn your energy data into cost savings and uptime gains.
2 MWh BESS — based on our team's prior work at steel plants in Maharashtra eliminating peak demand charges.
Community storage + EV charging hub — based on our team's prior experience deploying similar projects in Bengaluru.
10 MWh BESS co-located with a solar farm — based on our team's prior grid-scale BESS project experience in Rajasthan.
We combine deep engineering knowledge with hands-on site experience to deliver solutions that work in Indian grid conditions, climate, and regulatory environments.
Detailed simulation-based sizing for every project — no guesswork, no over-engineering.
Every system meets CEA, IEC, and IS standards with full fire, arc-flash, and BIS certification support.
Cloud-connected EMS with real-time alerts, AI anomaly detection, and remote diagnostics.
From feasibility study to O&M — one team, one point of accountability across the full lifecycle.
