At 110 km/h, climbing a mountain road, an EV uses far more energy than it does in the city. The dashboard only notices halfway down the highway. EV Control reads the battery through the OBD2 port and works out, before you leave, what percentage you'll arrive with, factoring in the route, the climbs, the weather and highway speed.
The dashboard tells you how many km are left based on the last few minutes of consumption. It doesn't know there's a mountain climb ahead, that it's going to rain, or that you're about to hit 110 km/h on the highway.
You leave with 80% and find out halfway there that you'll arrive with 9%. The dashboard only looks backward.
The battery is the most expensive part of the car. How much has it already lost? The dashboard doesn't say. When it's time to sell, nobody knows.
How much went in, how long it took, at what power, what it cost. It all fades from memory by the next day.
This is the real usage sequence. Tap each step or let it play.
Real route, climbs and descents, temperature, rain, and your own consumption split between city and highway. Tap a charger on the map and the math redoes itself instantly.
Real capacity, measured on every big charge. A selling point at resale.
If one cell drifts away from the others, you know before the shop does.
Speed cameras from open map data, filtered by the car's heading. A red band shows if you're over the limit.
Every charge becomes a record with location, kWh and curve.
Did the auxiliary battery drop below 11.9 V? Instant notification.
Battery % floating over any app, plus a home-screen widget.
The app reads active, pending and permanent codes, explains each one in plain English and clears them once the problem is fixed. Before clearing, it saves everything to the history. If the code comes back, you have proof to take to the shop.
How much of your energy turned into km. Improve by driving smarter.
Generate a report with battery health, measured capacity, charging history and fault codes. Show it to the buyer and negotiate with hard numbers.
For PHEVs: km driven on electric × gasoline price × your home electricity rate. Fuel and battery side by side.
Each charge goes in with its price per kWh. The app shows the R$ per km and the month's spending.
Distance, duration, consumption, cost in R$ and driving score for every trip. Compare the same road on the way out and the way back.
Nearby chargers on the map, an alert when the charge hits your target, spreadsheet export, integration with a route planner (ABRP) and background operation with the screen off.
A Bluetooth LE OBD2 adapter in the port under the steering wheel. It stays there.
It finds the dongle and your car's profile. No manual PID setup.
Pick a destination. The app tells you if you'll make it, where to charge and how much will be left.

Born inside two real cars: a GWM Ora 03 and a 2024 Haval H6 PHEV. Every number on screen was read in the car, with a log, before it went into the app.

Requires a Bluetooth LE OBD2 dongle (ELM327) and an Android phone. Dongle sold separately.
Today it's validated on the GWM Ora 03 and the 2024 Haval H6 PHEV, with all data read in the car itself. Other EVs and hybrids with an OBD2 port are added as new profiles. If yours isn't on the list, contact us first and we'll confirm.
An ELM327 OBD2 adapter with Bluetooth LE (BLE). We tested with V-LINK and Vgate. Avoid classic Bluetooth ones: in our tests they dropped the connection most of the time.
The app doesn't change the control unit's configuration or programming. The only thing it sends to the car is the standard command to clear fault codes, the same one any workshop scanner uses, and only when you confirm.
No. Clearing only turns off the dashboard light. If the fault persists, the code comes back. That's why the app saves the history before clearing: you take the proof to the shop.
The dongle draws very little power. And the 12V guard warns you if the auxiliary battery drops below 11.9 V. If the car will sit unused for several days, unplug the dongle.
Battery readings work without internet. Route, weather, speed cameras and chargers use your phone's data.
Android only for now. An iPhone version is planned.
You have 7 days to try it. Don't like it? We'll refund the full amount.
The key appears on screen right after payment and is sent to your email. Lost it? with the email you used to buy.
