CellPulse reads every individual cell in your EV battery pack using a standard OBD-II adapter and gives you a transparent health score. WHAT YOU SEE - Health score 0–100 with * to ***** rating - Color-coded grid of every cell voltage — spot weak cells instantly - 24 battery temperature sensors - 12V auxiliary battery status - Pack configuration: capacity, chemistry, cell count - SOC spread across cells - Charge and discharge rate limits THE SCORE IS TRANSPARENT Four independent checks — the weakest one determines your overall rating: Cell balance: how tightly matched are the cell voltages? Temperature uniformity: are all cells the same temperature? SOC spread: how far apart are the cell state-of-charge values? Charge rate: is the battery accepting its full rated charge? No averaging that hides a bad result. Every factor is explained in the report. SHAREABLE PDF REPORT Generate a clean PDF with your score, cell chart, temperature map, and vehicle info. Share it when buying or selling a used EV, or keep it as a dated record of your battery condition. BUYING A USED EV? The dealer says "the battery is fine" — CellPulse shows you the actual numbers. Scan before you buy. Share the report with your mechanic. Negotiate with data. PRIVACY FIRST No account required. No location data. Scans run entirely on your iPhone. Optional anonymous telemetry shares only cell balance statistics. Your VIN is never sent — only a one-way hash used to prevent duplicate submissions. WORKS WITH VW ID.3 · ID.4 · ID.5 · ID. Buzz Audi Q4 e-tron · Q4 Sportback e-tron Škoda Enyaq iV · Enyaq Coupé iV CUPRA Born (All MEB-platform vehicles) REQUIREMENTS - iPhone, iOS 17 or later - BLE OBD-II adapter (Bluetooth Low Energy — not Classic Bluetooth or WiFi) - Car in Ready mode during scan Tested adapters: vLinker MC+, OBDLink CX, VEEPEAK BLE+.
