Here is the monthly data-based review of how much it costs to charge an electric car with and without the VOOL mobile app. The overview is based on the Tesla Model X, and we consider factors like mileage, electricity prices, and weather. We are writing this from Estonia, where summers are up to 30°C, and winters can be up to -30°C. Colder temperatures play a big role in electric car's range.

Most of the charging is done with a 22 kW VOOL EV Charger, which gives a realistic understanding of the common needs as about 80% of electric car owners charge their cars at home. Not all charging sessions have been made via app, tho.

VOOL App is a free Smart Charging app for any OCPP 1.6 compatible EV charger. It tracks the electricity prices and automatically selects the lowest hours. Market price based charging works across Europe. You can conveniently see all your charging data in one place, monitor the electricity prices for the next 24 hours, and charge directly via EV charger instead of communicating via the car's complex API. We do, though, recommend using a VOOL EV Charger for the most reliable charging experience.
