## What is TayScan?

Unlock Advanced Telemetry & Diagnostics for Your Porsche Taycan EV

TayScan gives Taycan owners, enthusiasts, and independent specialists deep insights into their high-voltage battery system, real-time vehicle telemetry, and fault management—all directly via a Bluetooth OBD-II adapter.

Key Features:

• Battery Health & SoH Reports
Generate official-style PDF Diagnostic Certificates detailing true State of Health (SoH), Max Usable Capacity (kWh), cell balance, and charging performance limits. Ideal for long-term health tracking or pre-purchase inspections (PPI).

• Real-Time Telemetry & Fast-Charge Monitoring
Track high-voltage pack voltage, cell span limits, average pack temperature, and real-time pre-conditioning status to ensure peak 270 kW DC fast-charging performance.

• Cell Voltage & Imbalance Matrix
Visualize individual cell voltages and track pack drift down to the millivolt (mV) level to verify anode-cathode balancing and pack integrity.

• OBD-II Fault Code Scanner
Quickly scan for Diagnostic Trouble Codes (DTCs) across battery management systems and vehicle gateways, inspect error details, and clear fault codes instantly.

• 100% Private & Direct
All vehicle queries run locally on your device via low-latency UDS commands. No account registration, subscriptions, or cloud servers required.

• Built-in Vehicle Simulator
Explore all telemetry screens and preview diagnostic metrics in Demo Mode without needing a physical vehicle connected.
