Electric mobility is revolutionizing the way we move around, and electric car chargers are electric car chargers play a key role play a key role in this transition. But how do they really work? Although plugging in an electric car seems as simple as charging a cell phone, behind this process there are a number of mechanisms that ensure efficient, safe and adapted charging for each type of vehicle.
In this article, we will explore step by step how the charging of an electric car is carried out, from the connection to the power source to the completion of the process. Read on to discover all the details!
Step-by-step loading process:
- Connection to power source
- The charger is connected to an electricity source (household socket, dedicated charging point or fast charging station).
- Communication between the charger and the car
- When the cable is connected, the car and the charger exchange information to determine the maximum power the battery can receive, to ensure safe charging and avoid overcharging.
- Energy conversion
- A car battery only stores direct current (DC). Therefore, if AC mains electricity is used, it is necessary for the car’s built-in converter to convert it into DC.
- Regulation and protection
- The battery management system (BMS) regulates charging to prevent overheating and damage. The charging rate is progressively reduced to protect battery life when the battery is close to its maximum capacity.
- Completion of loading
- Once the desired charge level or 100% is reached, the charger automatically cuts off the flow of electricity.

What types of electric car chargers are there?
Electric car chargers are devices designed to recharge the battery of an electric vehicle (EV) by supplying it with electrical power from an external source. If you are thinking of making the leap to an electric vehicle or already have one, knowing what options exist to recharge it is essential.
In this article we explain the types of chargers for electric cars, their characteristics and which one may be the most suitable for you.
Chargers for electric cars can be classified according to their charging speed and the type of current they use:
1. Electric car charger type 1 (AC – Slow Charge) ⚡
This type of charger is one of the most basic and is often used in the home. It uses alternating current (AC) and is connected to a conventional household socket (Schuko plug).
- Power: Up to 3.7 kW
- Electric car charging time: Between 8 and 20 hours, depending on the model.
- Ideal for: Occasional use or vehicles with small batteries
- Advantages: No special installation required
- Disadvantages: Very long loading time
2. Wallbox type chargers (AC – Semi-fast charge) ⚡⚡
The most common domestic charger for electric cars is the Wallbox type. It is installed in private or communal garages and requires an adapted electrical installation.
- Power: Between 3.7 kW and 22 kW
- Charging time electric car: 3 to 8 hours
- Ideal for: Daily use at home or at work
- Advantages: Faster, safer and more efficient charging
- Disadvantages: Requires professional installation
3. Fast chargers (DC – Fast Charging) ⚡⚡⚡
Fast chargers for electric cars are mainly found at public charging points, such as gas stations, shopping malls or highways.
- Power: From 50 kW up to 150 kW or more
- Charging time: 30 minutes to 1 hour for 80% of battery life
- Ideal for: Long distances or quick recharges on the road.
- Advantages: Fast charging, ideal for travel
- Disadvantages: High price per charge, more costly to install
4. Ultra fast chargers (DC – Ultra Fast Charging) ⚡⚡⚡⚡
These are the most advanced and are increasingly being installed on highways and in high traffic areas. They allow high-speed charging for compatible vehicles.
- Power: From 150 kW to 350 kW
- Charging time: Less than 20 minutes
- Ideal for: Latest generation vehicles and users in a hurry
- Advantages: Extremely fast charging
- Disadvantages: Requires compatible batteries and high cost
In summary:
| Type of charger | Power | Approximate loading time | Type of current | Necessary installation | Recommended use |
| Domestic socket (Schuko) | Up to 3.7 kW | 8 – 20 hours | AC | No | Occasional use, emergencies |
| Wallbox (semi-fast charging) | 3.7 – 22 kW | 3 – 8 hours | AC | Yes | Daily use at home or at work |
| Fast charger | 50 – 150 kW | 30 min – 1 hour (80%) | DC | Yes (on public roads) | Long trips, fast recharging |
| Ultra fast charger | 150 – 350 kW | < 20 minutes (80%) | DC | Yes (advanced infrastructure) | New vehicles, intensive use |
🚗 What type of charger do you need?
The choice of electric car charger depends on how you use your vehicle, your daily routine and the access you have to electric car charging points. For most users, a Wallbox-type home electric car charger is sufficient for overnight charging. For companies or fleet users, it may be interesting to install fast or even ultra-fast chargers.
If you are thinking of installing an electric car charging point, it is best to have professional advice to help you choose the ideal solution for your vehicle and your lifestyle. Contact us.
How long does it take to charge an electric car?
One of the most common questions among those who are thinking of switching to electric mobility is: how long does it take to charge an electric car? The answer depends on several factors, such as the type of charger, the battery capacity and the vehicle’s state of charge. In this article we explain everything you need to know about charging times and what options exist to recharge your vehicle efficiently.
🔋 Factors influencing loading time
The charging time of an electric car is not always the same. It changes depending on:
- Battery capacity (kWh): The larger it is, the more energy you need to reach 100%.
- Type of charger: There are slow, semi-fast and fast chargers, each offering different power ratings.
- Initial state of charge: Charging from 10% is not the same as charging from 50%.
- Contracted power at home: This directly affects the charging speed if you use a domestic Wallbox.
- Ambient temperature: Sometimes extreme cold can slow down charging.
🏠 How long does it take to charge an electric car at home?
With a Wallbox home charger, the most common is to charge the car at night, taking advantage of cheaper rates. For example, if you connect your car at 22:00, when you wake up in the morning it will be fully charged and ready for the day. This is the most convenient and efficient option for daily use.
💡 Is it possible to charge to 100% with fast chargers?
Technically yes, but it is not recommended. Many manufacturers limit the power as the battery approaches 100% to protect its lifetime. Therefore, fast chargers are often used to reach 80% in a short time and continue the journey.
✅ Conclusion
Charging time for an electric car can range from less than 30 minutes to more than 10 hours, depending on the type of charger, battery and installation. If you have a charging point at home and charge overnight, you will not notice any waiting time. For long trips, fast charging points are a perfect solution.
In addition, some European countries offer subsidies and grants to facilitate the installation of recharging points in private homes and communities.
