CellGrader
Battery module grading and second-life matching marketplace
The Problem
EV battery packs retire at 70-80% capacity. Individual modules range from 60-95%. Second-life applications need matched modules. Currently, grading is manual, expensive, and prevents the circular battery economy from scaling.
Why You Win
You understand cell balancing, impedance spectroscopy, and the degradation mechanisms that determine remaining useful life. This is electrochemistry, not software.
Solo Founder Path
Build a standardized testing protocol and grading system. Match graded modules with second-life buyers (stationary storage, backup power). Start with one recycler partner.
How AI Agents Scale It
AI agents run automated test sequences, grade cells against standardized criteria, match supply with demand, and optimize second-life allocation across the marketplace.
Market Background
The electrification and EV segment represents a $4.8B market opportunity. EV battery packs retire at 70-80% capacity. Early movers building AI-native solutions in this space can capture significant market share before incumbents adapt their legacy offerings.
