Electric driving is on the rise, yet many drivers have concerns about charging via a standard household outlet. Is it truly safe? And how can you ensure that your vehicle charges correctly and without risk? In this blog, we answer these questions and provide practical tips for safe charging.
How safe is charging via a household outlet?
The short answer: yes, it is safe—provided you take the right precautions. Charging through a grounded standard outlet is perfectly fine as long as you use the correct cables with built-in safety features.
According to network operator Fluvius and the Flemish government, you should always use a Mode 2 charging cable with integrated protection, such as an ICCB (In-Cable Control Box) or IC-CPD (In-Cable Control and Protecting Device). These cables, often included when purchasing an electric vehicle, protect against overloading, short circuits, and other electrical issues.
Why is this protection necessary?
Charging directly from a standard outlet without safety measures is not allowed. Without additional protection, you risk overheating, damage to your electrical system, or even fire hazards. Mode 2 charging cables ensure that the power flow is regulated, protecting both your vehicle and your home.
How to safely charge via a standard outlet?
- Use a grounded socket: A properly functioning grounded outlet is crucial. It helps to safely dissipate excess electrical currents.
- Use the correct charging cable: Make sure your charging cable has built-in protection, such as IC-CPD. These cables communicate with your vehicle and regulate the charging speed to prevent overloading. If your cable lacks this protection, you can purchase one from your car dealer or a certified supplier. Ensure the cable is CE-certified.
- Avoid extension cords and power strips: Standard extension cords and power strips increase the risk of overheating, especially if they are not fully unrolled.
- Limit charging current to 10A: The built-in protection in your charging cable limits the current to a maximum of 10A, which corresponds to a charging power of 2.3 kW. This provides about 10-12 km of range per hour. A full night of charging gives you over 100 km of range, sufficient for most daily commutes.
- Check your electrical installation: Not sure if your home’s electrical system is up to the task? Have it inspected by a certified electrician to reduce the risk of electrical faults.
Why choose charging via a standard outlet?
Beyond safety, charging via a household socket offers several advantages:
- Cost-Effective: Charging at home using a standard outlet is cheaper than public charging stations or fast chargers. Using a home charging station can also result in higher electricity costs due to increased capacity tariffs, affecting your entire household energy bill (e.g., heating, appliances).
- Simple & Flexible: No expensive installations or inspections are required. Just plug in and charge!
- Less Battery Wear: Slower charging extends battery lifespan by generating less heat and reducing stress on the battery cells.
Smartly manage your charging consumption?

This small device plugs into your outlet and automatically records your charging data via an app. It allows you to generate split invoices for private and business use, making it ideal for self-employed professionals and employees with a company car.
Conclusion: charging via a standard outlet is safe, simple & cost-effective
Charging your EV through a standard household outlet is not only safe but also convenient and economical—as long as you follow the right precautions. Use a grounded socket, a certified charging cable with built-in safety, and avoid extension cords. With these simple steps, you can charge your EV worry-free.
