CellForge reads a Tesla battery pack straight from the car's own battery computer: every brick, every module, every temperature sensor. The result is a Battery Integrity Report written for that specific car, and no other.
A used electric car's value lives or dies with its battery pack, and until now that pack has been a black box: a charge percentage on a screen and a seller's word. CellForge opens the box. A short test reads the pack the way the car itself sees it, all 96 cell groups (bricks) across 16 modules, and turns the raw numbers into a permanent, checkable report page with its own report ID.
The test connects to the car and listens to the battery computer's own broadcasts. It is listen-only: nothing is written to the car, nothing is changed.
Every brick voltage, every module temperature, the pack voltage and the charge level are captured while the car sits at rest, then cross-checked against the pack total.
A permanent page like the sample: the full cell map, imbalance in millivolts, the thermal picture, a grade with its basis shown, and a plain-words analysis of what it all means.
All 96 bricks drawn in their modules, colored by how far each one sits from the pack average. Tap any brick to see its exact voltage. A weak brick has nowhere to hide.
The gap between the highest and lowest brick, the single clearest balance signal a pack gives at rest. A healthy pack rests tight; the report says exactly how tight.
Thirty-two temperature sensors across the pack: average, spread, and uniformity. Heat that pools in one module tells a story the voltages alone cannot.
One letter grade at the top, and the numbers and grading bands it came from one tap below it. Estimates are labeled estimates, with the method explained.
This early capture delivered 72 of the 96 bricks; the other 24 are shown as no data, never filled in with guesses. Open the full report to explore every brick.
A CellForge report is a snapshot of one pack at one moment, read from the car's own numbers. It is evidence, not a warranty, and every report says so on its face.
The same test that issues these reports is being built into a standalone app, CellForge Battery Integrity, so any owner or shop can run it. Reports come first; the app follows when it is ready, not before.
