Battery Aadhaar:
A digital identity
for every cell.

The EV ecosystem is blind to what's happening inside its batteries. We built the infrastructure to change that — permanently.

The Problem

The EV industry is flying blind on battery health

The EV space is expanding at a phenomenal rate. But as the industry races toward its promised future, a few basic and rudimentary things have failed to keep pace — and they're holding everything back.

Whether you're an EV user, financier, or stakeholder, you've felt it: a creeping uncertainty around the questions that matter most. Is the battery performing at its best? Is it being used correctly? How much longer before it needs to be retired?

Some answers exist — but they're approximations. Extrapolations of how a battery in ideal, controlled conditions would behave. Real-world use is rarely ideal. Real-world data has barely existed.

"To properly answer these questions, any battery has to be accounted for at every step of its process — from the moment it's born to its entire first life and beyond."
The Solution

What is Battery Aadhaar?

Just as India's Aadhaar card is a comprehensive digital identity containing pertinent information about an individual, Battery Aadhaar is a foundational digital identity for every battery cell — not just for identification, but as a living record of its components, health, capacity, and usage throughout its entire lifetime.

Without Battery Aadhaar
Battery health is an estimate based on lab conditions
No real-time usage data accessible to financiers
Second-life viability is guesswork
Cell-level degradation invisible across the value chain
Each stakeholder works with incomplete, siloed data
With Battery Aadhaar
Real-world SOH and RUL tracked continuously
Usage, charge cycles, and environment all recorded
Second-life decisions backed by actual data
Cellular-level visibility from birth to retirement
Transparent, incorruptible data shared across the ecosystem
How It Works

Tracking a battery across its entire lifecycle

Battery Aadhaar isn't a snapshot — it's a continuous record. From the moment a cell is manufactured to the end of its usable life, every relevant data point is captured and written to its identity.

01
Birth & Registration
Cell manufactured, identity created. Baseline chemistry, specs, and provenance locked in.
02
First Life Monitoring
Every charge cycle, temperature event, discharge rate, and trip logged in real time.
03
Health & Optimisation
SOH and RUL computed continuously. Alerts, recommendations, and VPP eligibility assessed.
04
Second Life & Retirement
Full first-life history informs repurposing decisions — stationary ESS, grid backup, or safe retirement.

Beyond the First Life

The data that unlocks a battery's second life

One of the most undervalued dimensions of Battery Aadhaar is what it enables after a battery's primary use is complete. The data recorded throughout a battery's first life — its real degradation curve, actual usage patterns, thermal history — dramatically improves the viability of second-life applications.

Without this data, repurposing a used EV battery for stationary storage is a gamble. With it, you're making an informed engineering decision. Unnecessary waste is reduced. Asset value is extended. The economics of the entire EV value chain improve.

What second-life decisions Battery Aadhaar enables
  • Stationary ESS deployment — cells with sufficient remaining capacity routed to grid storage applications
  • Commercial backup power — degraded packs repurposed for lower-demand, non-mobility use cases
  • VPP participation eligibility — health data determines whether a battery qualifies for virtual power plant programmes
  • Safe retirement routing — cells that can't be repurposed are identified early, reducing hazardous waste risk
"Just as Aadhaar became the foundation for OCEN, UHI, and beyond, Battery Aadhaar holds the same potential — a data layer that opens the floodgates for future innovation across the entire energy ecosystem."
Ecosystem Impact

Transparent data for every stakeholder

Battery Aadhaar was built to be an ecosystem enabler, not a proprietary tool. The information on any Battery Aadhaar is transparent and incorruptible — accessible to every participant in the value chain who needs it.

EV Users
Know exactly how their battery is performing, not an approximation. Make informed decisions about usage and charging behaviour.
Financiers
Underwrite battery-backed assets with real data. Assess residual value, monitor fleet health, and reduce credit risk on EV loans.
Cell Manufacturers
Receive real-world performance feedback from deployed cells. Improve chemistry and manufacturing quality with field data, not assumptions.
Fleet Operators
Monitor every battery in the fleet simultaneously. Predict failures before they happen. Optimise charging schedules across the entire operation.
Grid Operators
Qualify batteries for VPP and demand-response programmes based on verified health data — not manufacturer specs that no longer reflect reality.
Regulators & Policy
Access aggregate, anonymised fleet data to inform battery safety standards, recycling mandates, and EV adoption policy decisions.
In Summary

Battery Aadhaar is the foundation layer the energy ecosystem was missing.

We built it to be the best marketplace asset management tool anyone can ask for — not just for TEC, but for the entire value chain. Our goal: every battery gets a Battery Aadhaar that accounts for its complete lifecycle, at a cellular level. The data that flows from it will power a more sustainable, efficient, and innovative energy ecosystem.
