The hidden cost
Your battery is quietly losing value. You just can't see it.
The dashboard shows a range number, not the truth. Degradation, cell imbalance, and charging habits erode resale value long before any warning light. Dr.EV surfaces it early, so you can act or sell at the right time.
✓See true State of Health, not the optimistic dashboard number.
✓Catch cell imbalance and Supercharging wear weeks early.
✓Get an AI-verified report that proves value when you sell.

The engine inside
Powered by BatterMachine's ML core engine.
Dr.EV runs on the same physics-informed AI that diagnoses commercial fleets and grid storage, validated on real-world vehicles, not lab benches.

What is Physics-Informed AI?
It fuses electrochemical physics with machine learning, the model learns how a battery actually behaves, not just data patterns, so it stays accurate even where data is thin.
Real-time ingestion
Charging telemetry streams in from active Teslas.
Continuous learning
Models refresh automatically as new data arrives.
Rising accuracy
More data means sharper diagnosis over time.
Cloud Dataset
Data collection
Fleet telemetry, battery chemistry, and degradation trajectories are continuously ingested.
Physics-Guided Learning
Model training
Physics-informed features combine electrochemical domain knowledge with machine learning.
Diagnosis & Prediction
AI inference
Risk engine, anomaly detection, and degradation models produce precise diagnostics.
Outputs & Feedback
Actionable results
Forecasts, alerts, and risk scores feed back to keep refining the model.

Rated 4.8★ by Tesla owners
★★★★★
Professional battery management
“After using it for a day, I found there was a lot to explore. I keep opening the app because it provides so much information, including driving data, charging data, battery score, and estimated range. Vehicle alerts are easy to overlook until you tap them on the car screen, so it was great to receive them through the app as well. I would also appreciate more detailed explanations of what the various figures mean and which values are normal or abnormal.”

★★★★★
Packed with varied and essential information
“While connecting and setting up the vehicle, I could easily check a variety of battery-related information, and the explanations made it easy to understand. It feels like a very convenient app to use, and I'm really looking forward to using it more. If possible, could you add manual preconditioning to the vehicle controls? It would be useful when using third-party fast chargers.”

★★★★★
An essential EV management app
“You might not need it if you never think about these things, but if you want to manage your EV because of battery-related concerns, this is an essential app. It seems especially necessary for Tesla owners. The intuitive, detailed explanations and responsiveness make it feel trustworthy to use. I hope the app continues to receive consistent updates.”
