My EV Companion – Smarter Charging, Lower Costs, Less Guesswork
Meet My EV Companion, your everyday co-pilot for EV ownership. Whether you drive a Tesla, Rivian, or any other EV, this app helps you understand your real costs, plan cheaper charging, and squeeze more value out of every kWh—without spreadsheets or guesswork.
Charge at the Right Time (New: On-Device Neural Net. Beta)
Stop wondering “Should I charge now or later?”
The new Cheapest Time to Charge tool uses an on-device neural network to scan the next 24 hours and highlight when prices are likely to be lowest at your nearby fast chargers.
See a clear “Best 1-Hour Window” for charging
Compare best price vs typical price and daily range
All predictions run on your device – no account required
Understand Your Real EV Costs
My EV Companion turns your charging and trip data into real-world numbers you can act on:
Cost per kWh & cost per mile – home vs public charging
Cost of Ownership – see how your EV stacks up against a gas car
Budget & forecast tools – estimate monthly EV costs, not just “ideal” EPA numbers
Gas → kWh converter – instantly compare gas prices to EV energy costs
Deep Analytics for EV Nerds (In a Good Way)
If you love data, this app loves you back:
Session Analytics & Efficiency Charts – spot expensive patterns and outliers
Spark Panel (AI Summary) – human-readable summaries of your recent EV spending and usage
Forecast Dashboard – peek ahead at projected charging costs by category (home, fast charging, road trips)
Bring Your Data With You
Already track your life in other tools? My EV Companion plays nicely:
CSV Charging Wizard – import charging logs instead of starting from scratch
