Frequently Asked Questions

1. What types of chargers exist for electric vehicles?

There are three main types of chargers:

  • Slow (Mode 2) – Plug into a standard household socket and take longer to charge.
  • Semi-fast (Mode 3) – Used at home or in public spaces, offering more efficient charging.
  • Fast (Mode 4) – Charging stations that can charge the battery up to 80% in just a few minutes.

Yes, but it is not the most efficient solution. Standard household sockets (230V) provide slow charging and may take several hours to fully charge the battery. For greater safety and faster charging, a wall charger is recommended.

 

It depends on the charger’s power and the vehicle’s battery capacity:

  • Household socket (up to 3.7 kW): 8–24 hours
  • Charging pillar or wallbox (7.4 kW to 22 kW): 3–8 hours
  • Fast charger (50 kW or more): 20–60 minutes to reach 80% charge

The cost varies depending on the location and the electricity tariff:

  • At home: It may cost between €2 and €5 per 100 km, depending on the electricity price.
  • Public charging stations: Prices vary but can range from €0.15 to €0.50 per kWh.
  • Fast charging: It can be more expensive, reaching around €0.60 per kWh.
If you want to charge your car faster and more safely, yes. A dedicated charger allows for more efficient charging and reduces electrical risks.

These are types of connectors used to charge electric vehicles:

  • Type 1 – More common in older vehicles, it has five pins and supports single-phase charging.
  • Type 2 – The most widely used in Europe, it has seven pins and allows faster charging.
Fast charging may cause slightly more battery wear over time, but modern battery management systems are designed to prevent significant damage. To help extend battery life, it is recommended to alternate between regular charging and fast charging.
Yes, chargers and connectors are designed to be safe even in rainy conditions. However, it is recommended to charge the vehicle in protected areas whenever possible.

Most batteries have a lifespan of 8 to 15 years, depending on usage and maintenance. Most manufacturers offer warranties of 7 to 10 years or 150,000 to 200,000 km.

Yes, as long as you use a proper charger with a certified installation. Electric vehicles have built-in protection systems that prevent overcharging and automatically stop charging when the battery is full.

  • kW (kilowatt) – Measures the power of the charger (e.g., 7.4 kW, 22 kW, 50 kW). The higher the value, the faster the charging speed.
  • kWh (kilowatt-hour) – Measures the battery capacity and the car’s energy consumption. For example, if a car has a 50 kWh battery and a 10 kW charger, it will take about 5 hours to fully charge.

It is not recommended. Extension cords can overheat and create electrical safety risks. If you need more reach, it is better to install a wall charger in an accessible location.

Yes! If you have solar panels at home, you can use an inverter and a compatible charger to power your vehicle with electricity generated from the sun, further reducing your carbon footprint and energy costs.
If the battery is completely depleted, the car will stop working, just like a combustion vehicle that runs out of fuel. Some roadside assistance services already offer emergency charging, or the vehicle may need to be towed to the nearest charging station.
  • Avoid charging to 100% or discharging to 0% too often.
  • Prefer slow or regular charging, using fast charging only when necessary.
  • Park the car in cool places and avoid exposure to extreme temperatures.

It depends on your contracted power and the vehicle you own. If you have a three-phase electrical installation and a car that supports 11 kW or 22 kW charging, a three-phase charger can significantly reduce charging time compared to a 7.4 kW single-phase charger. However, if your installation is single-phase, upgrading the electrical infrastructure may be necessary.

Yes. Not all electric vehicles can take full advantage of the power offered by fast chargers. If a car supports a maximum DC charging power of 50 kW, connecting it to a 150 kW charger will not increase the charging speed beyond the vehicle’s limit.

Battery thermal management and protection systems reduce the charging speed as the battery approaches full capacity. This helps prevent overheating and extends the battery’s lifespan.

The car will only draw the maximum power it is capable of handling. For example, if a vehicle supports a maximum of 7.4 kW AC charging, connecting it to a 22 kW charger will not reduce the charging time.

  • Ambient temperature – Extremely cold weather can reduce battery efficiency.
  • Battery condition -Degraded batteries may charge more slowly
  • Different chargers and conversion systems can affect efficiency
  • The vehicle’s software and battery management system influence how charging is managed.
Vehicle-to-Grid (V2G) allows the car to send energy back to the electrical grid when needed, helping to stabilize energy demand. Vehicle-to-Home (V2H) allows the vehicle’s battery to supply power to a home when necessary. These technologies are not yet widely available, but they have significant potential for the future.
The charging curve refers to how the charging power changes over time. Typically, electric vehicles charge faster when the battery level is between 10% and 50%, and the charging power gradually decreases as it approaches 80%–100% to protect the battery and prevent overheating.
Yes, many home chargers and even some public charging stations allow you to adjust the charging power. This can be useful to avoid consumption peaks, charge during lower-cost electricity periods, or protect the electrical installation.
Dynamic load balancing automatically adjusts the charger’s power based on the home’s current electricity consumption. This prevents overloads and allows the vehicle to charge without exceeding the contracted power from the grid.

Yes, if you want to optimize energy consumption and monitor charging sessions. Smart chargers allow you to:

  • Schedule charging times during periods of cheaper electricity.
  • Adjust the charging power as needed.
  • Integrate with solar systems to make use of renewable energy.
  • Access the charger remotely and track your charging history.
Over time, the internal resistance of the battery increases, reducing its ability to absorb energy efficiently and generating more heat during fast charging. This can lead to a reduction in the maximum supported charging power and longer charging times.

A semi-fast AC charger is a device used to recharge electric vehicles using alternating current (AC) at a moderate power level, typically between 7 kW and 22 kW.

An AC charger delivers power to the vehicle’s onboard charger, which converts the alternating current (AC) into direct current (DC) to charge the battery. A DC charger, on the other hand, supplies direct current directly to the battery, allowing for much faster charging.
The charging time depends on the battery capacity and the charger’s power. On average, a 7 kW charger may take 4 to 8 hours for a full charge, while a 22 kW charger can reduce this time to around 2 to 4 hours.
Most electric vehicles can be charged using AC chargers, but the maximum charging power may be limited by the vehicle’s onboard charger. For example, some vehicles support up to 11 kW AC charging, while others can charge at up to 22 kW.
The main difference is the charging power. A 7 kW charger usually operates on a single-phase connection, while a 22 kW charger requires a three-phase connection, allowing for faster charging times.
Yes, especially 7 kW models, which can be installed in homes with a suitable electrical infrastructure. 22 kW models may require a three-phase electrical installation, which is not always available in residential properties.
