## What is EV?

EV-BOY Pulse helps EV drivers turn supported on-board diagnostic data into clear, practical guidance.

Built and validated first for Nissan LEAF and BMW i3, it helps you understand battery condition, 12V behaviour and stored fault codes without having to interpret a wall of raw numbers.

BATTERY VERDICT, WITH CONTEXT

See a plain-English battery verdict alongside supported battery-health readings, state of charge, usable-capacity estimates and cell-balance context.

Reading confidence helps you judge whether a result is ready to rely on or whether a better test condition may improve it.

12V SYSTEM CHECK

Use guided readings to check the auxiliary 12V system. EV-BOY Pulse shows collection progress, a stable reading and clear next-step guidance when a result may deserve further attention.

FAULT CODES EXPLAINED

Scan supported stored diagnostic trouble codes and view a plain-English explanation, severity indication and sensible next step. Focus on what to investigate rather than a wall of technical codes.

MADE FOR NISSAN LEAF AND BMW i3 FIRST

Nissan LEAF and BMW i3 are the first fully validated vehicle profiles. Further EV profiles will be added only as they are validated.

WHAT YOU NEED

EV-BOY Pulse requires a compatible Bluetooth Low Energy (BLE) OBD adapter and a supported vehicle for live diagnostic readings. Adapter compatibility and available data can vary by vehicle, model year and connection quality.

IMPORTANT

EV-BOY Pulse provides model-based diagnostic guidance from on-board data. It is not a manufacturer inspection, safety certification, warranty decision or repair guarantee. For safety-critical, persistent or urgent vehicle faults, obtain professional diagnosis.

## Version history (last 3 releases)

### 1.22.164 — 2026-10-12

- Stress Check now grades only on fresh battery cell readings taken at 40% charge or below, and shows how many of the 5 required readings you have.
- New "Email results to EV-BOY" button on Stress Check reports (needs the Mail app set up on your iPhone).
- Grade colours are easier to read, and the grading bands are marked as provisional.

### 1.22.118 — 2026-09-18

Your readings now belong to a car

Pulse keeps each car's readings separate, so one car's battery can never appear in another car's trend as a false recovery.

If your earlier readings were saved before Pulse recorded which car they came from, you'll find them on the Trends tab under "Earlier readings" — all of them, nothing removed. They're listed rather than drawn on the graph, because plotting them could show another car's battery as this one's. Your trend line starts again from your next connect.

Also in this build
• Sharing a session log, a cells CSV or an email to the developer now sends the actual contents. Previously these could arrive empty.
• Home shows live power while you drive — kW out under acceleration, kW in under regen or charging — instead of leaving you to read the sign of a current.
• The "drive under load" step now shows how close you actually are, rather than a raw sensor number measured against the wrong scale.
