Ev Analyzer - EV Health doctor Live

Ev Analyzer connects to your electric vehicle through an ELM327 OBD2 adapter and gives you real-time diagnostics, cell-level insights, guided battery tests and professional health reports right on your phone. The best part? It’s completely free with no ads. 100% free for everyone. See every cell in your battery pack Most EV owners only see a single SoC value. Ev Analyzer goes deeper. On supported vehicles, the app reads individual cell voltages and displays them in a clean bar chart. Spot weak cells, detect imbalance and understand what is really happening inside your battery. Know your battery’s real condition Battery Health Check gives you a complete assessment of your pack. It analyzes State of Health, cell balance, voltage, current, capacity, temperature, 12V battery data and vehicle-specific values where available. Each metric gets its own score, combined into an overall grade from A to F. Test your battery under real load Battery Run and Battery Load Test show how your pack behaves while driving, discharging or accelerating. Track cell voltage spread, current, voltage sag, power and temperature under load. The app can estimate pack resistance and reveal weak cells that may look normal during a static scan. Find persistent weak cells One scan can show temporary imbalance. Ev Analyzer can track weak-cell patterns across repeated tests, helping you identify cells that keep appearing as weak over time. Live data while you drive or charge Watch SoC, pack voltage, current, power flow, available charge/discharge power and multi-sensor temperatures update continuously. On supported vehicles you can also see remaining usable energy, 12V battery voltage and detailed cell data. Monitor charging sessions Charging Monitor tracks charge power, energy added, battery temperature, voltage, current and taper behavior so you can see how your EV charges in real conditions. Check thermal and 12V performance Thermal Performance helps you see how the battery heats under load and cools afterwards. The guided 12V test checks resting voltage, voltage drop, recovery and READY-mode regulation where data is available. Read and clear fault codes Read stored, pending and permanent diagnostic trouble codes from your vehicle. A built-in manufacturer-aware DTC catalog explains what codes mean, and you can save a scan before clearing codes from the app. Compare with the community Optional community comparison lets you compare your battery health and load-test results with similar vehicles and battery sizes. Sharing is opt-in and pseudonymous. Export professional reports Generate detailed battery health reports with score breakdowns, cell voltage charts, temperature data, charge statistics, capacity analysis and diagnostic context. Share them with a buyer, mechanic or keep them for your records. Adapter quality test Not all ELM327 adapters are reliable. Ev Analyzer includes an adapter quality test to help identify slow, unstable or incomplete adapters before deep EV diagnostics.
