## What is CellPulse?

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+. Most ELM327 BLE adapters work. The adapter plugs into the OBD-II port under your dashboard. A full scan takes under 60 seconds.

## Version history (last 5 releases)

### 1.0.7 — 2026-08-21

- Improved scan accuracy: fixed a bug where some battery packs showed
    incorrect temperature readings
  - The app now detects unreliable scans and asks you to retry instead
    of showing an inaccurate report
  - More reliable OBD adapter connection
  - Added support for Viecar and JFIND adapters
  - Better detection of incompatible diagnostic tools (OBDeleven,
    Carista, Carly)
  - Support for more VW Group MEB vehicle variants

### 1.0.6 — 2026-07-07

• Clearer help when the car isn't ready to scan — CellPulse now guides you to switch the car on (Ready mode) so the battery can be read.
  • Recognizes more OBD-II adapters, including ones with unusual names.
  • Reliability and diagnostics improvements.

### 1.0.5 — 2026-07-03

• Scan right after unlocking your car — no need to switch it fully on.
• Better at finding your adapter, with clearer help when none is found.
• A friendlier message when the car is asleep, instead of a timeout.

### 1.0.4 — 2026-06-24

New: Scan personas
Tell CellPulse why you're scanning a car — one you own, one you're shopping for, or one you're selling — so your reports adapt and your scans stay organized by
purpose.

Also in this update:
- More reliable adapter connection, especially the first scan after plugging in
- Correct model names for more EU vehicles (Škoda Enyaq, Audi Q4 e-tron, Cupra Born)
- Accurate health score on larger packs, including the VW ID. Buzz
- A "Need an adapter?" link on the connect screen
- Scans now upload reliably even on a weak signal

### 1.0.3 — 2026-06-17

- New anonymous usage stats — helps us see which OBD adapters work reliably and where the app encounters issues. No personal info, no VIN, no GPS. Opt out anytime in Settings → Anonymous Usage Stats.
- Cleaner telemetry opt-in screen with a clearer explanation of the fleet comparison dataset.
