The technology

Electrical Fingerprint™

One measurement. Seconds. 2,000 data points. CeLLife’s patented EFP™ technology captures a complete diagnostic profile from any battery, replacing traditional methods that take hours and deliver a fraction of the insight.

The technology

How Electrical Fingerprint™ Works

Traditional battery testing methods measure one or two electrical parameters and draw conclusions from limited data. EFP™ takes a fundamentally different approach.

A single measurement sweeps across multiple frequency ranges, capturing how the battery responds at each one. The result is a rich data signature, the Electrical Fingerprint, unique to every battery.

  • Low-freq Electrochemical aging — capacity fade and degradation patterns.
  • Mid-freq Internal resistance — contact quality and tab-weld integrity.
  • High-freq Mechanical faults — physical damage and structural anomalies.

Diagnostic outputs

Six Layers of Insight from One Measurement

State of Health (SoH)

Accurate remaining capacity assessment without hours-long cycling. Measured, not estimated.

State of Charge (SoC)

Precise charge level from the EFP™ signature, independent of BMS readings.

Defect Detection

Mechanical faults, tab-weld failures, internal shorts and micro-cracks identified in a single pass.

Cell Matching

Grade and sort cells by true electrochemical similarity for consistent module and pack performance.

Aging Prediction

AI models predict future degradation trajectory based on current fingerprint patterns.

Chemistry Recognition

Identify the cell chemistry (LFP, NMC, NCA, LTO) before handling, sorting or processing.

Comparison

One Solution Replaces Four

Most testing setups combine multiple methods to cover the full diagnostic picture. EFP™ delivers all of it from a single measurement.

The platform

Hardware and Software. One Integrated Solution.

Most diagnostic solutions bring either the measurement hardware or the analytics software. Not both.

Every EFP™ measurement feeds into AI models trained on a growing dataset. The models improve with every measurement, meaning diagnostic accuracy increases over time. Results are available instantly on the Battery Perfected Cloud platform, with API integration into your existing ERP or MES.

CeLLife is the only platform combining proprietary diagnostic hardware with AI-driven analysis in a single integrated solution. You get the data and the diagnosis from the same source.

Battery Perfected Cloud

All measurement data stored, visualized and accessible from one cloud platform. Traceable records for every battery tested.

API Integration

Connect EFP™ data to your existing ERP, MES or quality management systems via API. No manual data transfer.

Local Deployment

For environments where cloud connectivity is restricted or cybersecurity is a concern, EFP™ can operate fully locally.

AI That Improves Over Time

Every measurement adds to the training dataset. Diagnostic accuracy and predictive capability grow with use.
