Car consumption in electric mode: how can you measure it from home, accurately?
Sep 2, 2025
KWh/100 km – the basis of the new calculation
For electric cars, the unit of consumption is kilowatt-hours per 100 kilometers. From this number, you can determine how much energy is needed to cover a given distance. A small city car can consume 13-16 kWh, while a larger SUV can reach 20-22 kWh. However, this number depends not only on size but also on engine power, driving style, weather conditions, heating and cooling usage, road quality, and tire pressure.
Car consumption: measurement and monitoring at home
With home charging, the best part besides convenience is that you can get a complete picture of your car's energy consumption. If you use the Voltie wall charger and it connects to the app, you can review every charging session: when it started, how long it lasted, how many kWh you used. From this data, you can easily calculate how many kilowatt-hours the distance traveled cost – and how much that is in forints.
With Voltie app, you can easily calculate
The Voltie app logs the data, but in addition, you can optimize your charging habits with it. You can start charging when your solar system produces the most. This way, you can fully track your car's consumption, and once you have enough data, you can even manage it more consciously over time.
All this is done without having to log anything manually – the system automatically records, and the Voltie app presents the information in a user-friendly manner. An automatic report is sent to the specified email address at regular intervals (weekly, monthly, etc.). Moreover, you can also see when it’s advisable to stop charging to protect the battery. In the app, you can set it up to charge only up to, say, 80% – this is a gentle operating mode for the cells, and the car's range remains more stable as well.
As you can see, with Voltie, you can start or schedule the charging, and you can also count on it for long-term analysis of consumption. You can see how energy consumption has changed in the past month, how much of a difference, for example, colder weather made, or how much more consumption there was on different routes.
Car consumption: it’s good to be aware
Just as the sentence "consumes 6 liters" used to be basic information, today "eats 15 kWh per 100" becomes that. Electric car owners are increasingly aware of consumption, and this is not necessarily about saving money; rather, it allows for more precise planning of routes, charging, and even energy consumption at home.
