Buyer’s guide: Choosing an EV charging station for detached homes

Charging an electric vehicle at home is most comfortable and cost-effective when you have a high-quality, safe charging station. This guide will help you choose the Walle charging solution that best meets your needs.

How to charge safely at home

Safety is paramount in Walle chargers. Their reliable electrical components and over 40 years of experience manufacturing electrical equipment in Finland guarantee product quality and safe operation.

  • Avoid using a standard household outlet. Regular sockets aren’t designed for prolonged, high-power use—under sustained load, they can overheat or even pose a fire risk.
  • Charging stations specifically designed for electric vehicles are both safer and more efficient.

1. What should you consider when choosing a charger?

  • Power: Charging speed depends on how much power the charger can deliver and how your vehicle accepts it.
    • A 3.6 kW single-phase charger adds roughly 20 km of range per hour of charging (assuming 18 kWh/100 km consumption).
    • An 11 kW three-phase charger adds roughly 60 km of range per hour of charging (assuming 18 kWh/100 km consumption).
      Remember that your vehicle may limit the charging power—check your car’s maximum AC charging rate before choosing a charger.
  • Installation: When installed by a professional, the unit operates safely, and a five-year warranty applies to all Walle chargers. The detailed warranty terms are here.
  • Location: Carefully planning the charger’s installation site makes setup smooth and cost-effective. A well-chosen location can minimise civil works, such as trenching for cables.
  • Load Management: If your home’s electricity use is already high—e.g., for electric heating or a sauna—consider adding a load-management system alongside your charger.
    • Walle’s dynamic load management optimises the current used for charging so that your home’s total consumption never becomes excessive. This protects you from blown fuses and unnecessary headaches.
  • Scalability: Walle chargers are manufactured in Raisio, Finland, ensuring that identical units, parts, and service will always be available as your needs grow.
