Buyer’s guide for commercial properties & public charging

Walle is a durable charging solution. The growing number of electric vehicles demands reliable and scalable charging infrastructure for properties and public spaces. In this guide, we offer practical information to help you choose the right charging solution.

1. Design principles

User groups and capacity requirements
In large properties, charging solutions serve office workers, customers, and visitors. Estimate the number of charging points needed based on user count, vehicle charging frequency, and future growth. Additional capacity may be required for public events. Typically, 20–50 % of parking spaces have charging stations.

Current and future needs
Modular solutions ensure that the charging infrastructure can easily expand as demand grows.

Placement of charging points
Charging points should be easily accessible, clearly marked, and well lit. When planning placement, consider convenience and safety. Locating chargers near entrances or other high-traffic areas increases utilisation rates.

Charging power and infrastructure
For properties, 11–22 kW charging stations are often suitable for daily use, whereas public venues may require fast or high-power charging of 30 kW or more to support quick turnover. To meet future needs, design the infrastructure with expansion in mind.

Wall-mount vs. bollard
All Walle chargers can be installed on a wall or a standalone bollard.

User authentication and billing
A Walle charging station can be integrated with the eParking service, enabling seamless user authentication, energy consumption monitoring, and billing when needed.

Installation flexibility
We partner with reliable, skilled installers across Finland. Professional installation of Walle chargers carries a five-year warranty.

Scalability
Beyond your current requirements, you may need to add more charging points in the future. It’s wise to ensure that identical or visually matching units remain available.

2. Why choose Walle?

Finnish manufacturing expertise is reflected in the quality of Walle chargers in many ways:

  • High-quality, practical design
    Metal-constructed charging stations are built to withstand the test of time, heavy use, and Finland’s variable weather conditions. Trafomic Oy—located near Turku in Raisio—has been manufacturing electrical equipment for over 40 years so that you can trust Walle chargers' electrical components and craftsmanship.
  • Five-year warranty
    Our products come with a five-year warranty when installed by a professional, ensuring worry-free operation for years to come.
  • Service and spare parts availability
    A domestic manufacturer guarantees quick access to spare parts and fast service if any issues arise.
  • Versatility
    The units support all common charging standards, such as Type 2 and CCS, and are suitable for private and corporate customers.
  • Smart features and management
    Walle chargers can be equipped with eParking remote-management software, enabling monitoring of charging stations, energy-consumption reporting, and integration with payment systems. This keeps the user experience seamless and operations efficient.

3. Energy management and cost efficiency

Grid load and control
Dynamic load management optimises the energy usage of charging points so that the property’s other power consumption is never compromised. Load management distributes available power among multiple points based on their utilisation.

Integration of renewable energy
Charging solutions can be paired with solar panels or other renewable energy sources. In this way, the charging network supports carbon-neutrality goals.

3. Suitable Walle charges for properties and public charging

A properly chosen and installed home charging station makes electric vehicle ownership smooth and worry-free. A Finnish-made Walle charger is a safe, durable, and service-superior choice.
