What does charging an electric car at home mean? We will show you the differences!
Jun 26, 2025
Ha belevágtál az elektromos autózásba – vagy már évek óta gurulsz hangtalanul –, biztosan felmerült benned: mivel, hogyan és mennyi idő alatt töltsem fel otthon a járművet? Az elektromos autó töltése otthon nem ördöngösség, csak ismerni kell a lehetőségeket. Ebben a cikkben rávilágítunk a váltakozó áram (AC) és az egyenáram (DC) közötti különbségre, valamint szó lesz a vésztöltőkről is. A végén pedig megmutatjuk, miért lehet szuper döntés a Voltie rendszerrel tölteni.
AC or DC? It matters!
Let's start with the basics: electric cars can be charged with two types of current. In households, we typically use alternating current, or AC, which are the "friendlier" home charging solutions. This includes wall chargers and the emergency chargers that come with the car. DC, or direct current, is generally associated with high-performance fast chargers, which we encounter mainly at public charging stations.
In AC charging, the alternating current (AC) coming from the grid is converted into direct current (DC) by the car itself with the help of an internal charging controller and rectifier. This device is called an on-board charger. A common misconception is to refer to it as an inverter, but the inverter actually works in the opposite direction: it converts direct current into alternating current – for example, in solar panel systems or to operate the electric car’s motor if it is an AC motor.
In terms of charging, we are therefore talking about a rectifier, not an inverter, which converts AC to DC so that the battery can be charged.
On the other hand, DC chargers already provide direct current to the car. Therefore, they are equipped with everything needed for the conversion: rectifier, charging controller, cooling, etc. These are faster but are typically more expensive and would not be worth operating at home. Meanwhile, an AC wall charger falls into the affordable category.
What about emergency chargers?
Most electric cars come factory-equipped with a charger that plugs into a standard electrical outlet, i.e., an emergency charger. This can also charge the car, but very slowly. It's good as a backup or if you want to charge temporarily at a weekend house. However, it is not a practical solution for longer distances.
Charging Electric Cars at Home: Why AC Charging via the Voltie System is Beneficial?
The Voltie wall-mounted AC chargers provide what you really need at home: convenient charging, optimizable energy use, and smart control. With the Voltie app, you can precisely set when, how much, and at what schedule your car should charge. You can choose from time-based, quantity-based, or battery-saving modes.
If you have a solar panel system, the Voltie systems dynamically adapt to production: the eco and green modes help utilize energy from sunlight. Installing the wall charger is quick and provides a long-lasting solution; moreover, the app also provides statistics that help you better understand how and when you use energy.
With Voltie, you can manage multiple chargers simultaneously, share access with family members, and even create detailed reports on your charging habits. Whether it's a single car or an entire fleet, Voltie helps organize and optimize electric car charging at every level.
Using the system is also very simple. The user-friendly interface is clear and logical, allowing you to set up your first charge in just a few minutes. With customizable notifications, you will never miss when the charge is finished or if any interruption occurred. This kind of traceability is flexible and convenient in every way.
