CellPulse: EV Battery Health

About this app

CellPulse is a transparent EV battery health scanner. Check your electric car's state of health (SOH) with a real, cell-by-cell read of the pack — not a guess, not a vague "good/fair/poor" rating with no math behind it.

Plug a BLE OBD-II adapter into your car, tap scan, and see exactly how your battery is holding up.

What CellPulse measures
• 96 individual cell voltages with full mV resolution
• 24 battery temperature sensors
• Pack capacity, state of charge, lifetime energy throughput
• 12V auxiliary battery health
• BMS firmware and battery manufacture date

Your transparent battery health score
A 4-factor score — cell balance, temperature uniformity, SOC spread, and charge rate. Each factor shows the actual measurement and the threshold behind the rating.
No black box. See cell imbalance and early degradation before they cost you range.

A shareable PDF report
Export the full report — ideal when buying or selling a used EV, or tracking your own pack's health over time. A history of every scan stays on your device; no cloud account needed.

Supported vehicles
VW Group MEB platform: VW ID.3, ID.4, ID.5, ID.7, ID.Buzz, Audi Q4 e-tron, Skoda Enyaq, Cupra Born.
Coming soon: Hyundai/Kia E-GMP (Ioniq 5, Ioniq 6, EV6, EV9, Niro EV, Kona EV).

Adapter required
You'll need a BLE OBD-II (OBD2) adapter — we recommend Veepeak BLE+, vLinker MC or OBDLink CX. See cellpulse.app/adapters for the current list.

What’s new

• 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.
