Question 1

Is MyEVBuddy really free?

Accepted Answer

Yes — every tool on MyEVBuddy is completely free to use, with no signup required. Battery health, route planning, cost calculators, warranty checks and everything else are all free. We keep the lights on with non-intrusive ads, not subscriptions or paywalls.

Question 2

Which EV brands does MyEVBuddy support?

Accepted Answer

MyEVBuddy works with 50+ manufacturers and 200+ models — including Tesla, BMW, Audi, Mercedes-Benz, Volkswagen, Hyundai, Kia, Nissan, Porsche and more. Whatever badge is on your bonnet, our tools use the same manufacturer specs and real-world data to give you accurate results.

Question 3

How does the battery health check work without an OBD dongle?

Accepted Answer

You don't need any hardware. The battery health calculator compares the energy your EV actually uses per mile — visible on your car's own trip computer or app — against your model's known efficiency and usable capacity. That gap tells us how much capacity has been lost, without an OBD-II dongle, CAN bus reader or dealer visit.

Question 4

Is my data stored anywhere?

Accepted Answer

Most tools run entirely in your browser and don't store anything. If you use the optional My Garage feature to track a vehicle over time, that data stays in your browser's local storage unless you choose to create a free account — only then is it saved to our database so you can access it from another device.
