Charging Stations for Businesses

The charging capacity determines the type of charging station and the impact on the electrical connection. We categorize companies’ needs into three scenarios.

1. Staff and visitors: 7- and 11-kW AC charging stations

An employee who spends eight hours in the parking lot doesn't need a fast charger. The Caro Series wallbox from SAJ delivers 7 kW (single-phase) or 11 kW (three-phase) and adds 50 to 80 kWh over the course of a workday—well more than the daily consumption of a company car. The wallbox prioritizes surplus PV power, so it charges using the building’s own solar power when production allows. This is the charging station for your clients’ offices, practices, and residential projects.

2. Short Stops and Fleet: DC fast chargers ranging from 30 to 480 kW

Delivery vans returning in the afternoon, taxis, car-sharing vehicles, and visitors who stay for 20 minutes: all of these require direct current. Frax supplies three DC chargers from SCU, all equipped with CCS2:

• EVMS-30: 30 kW, single gun, compact, for a single charging point on a limited connection. Charges about 150 km per hour.
• EVMS-80 to 200: dual-gun, modular design consisting of power modules; charges two vehicles simultaneously and dynamically allocates the available power.
• EVMS-240 to 480: dual gun for loading areas, logistics hubs, and transport corridors; capacity can be expanded by adding modules.

The modular design is the selling point for your customer: they start with 80 kW on their current connection and add modules as soon as the grid study or a grid upgrade allows for more power.

3. Connection too loose: the EVMS-ONE with battery

The EVMS-ONE combines a 120- to 240-kW DC fast charger with a 261- to 520-kWh LFP battery in a single enclosure. The battery recharges slowly via the existing connection and delivers the charging power to the vehicles in short sessions. A transportation company with a 100 kVA connection can thus still charge three trucks per day without waiting for Fluvius. For larger charging stations, you can apply the same logic to a battery container.

The charging capacity of a charging station ranges from 3.7 kW to 480 kW; the appropriate value depends on the vehicles' charging time.

• Single-phase AC: 3.7 to 7.4 kW, charging at 20 to 40 km per hour.
• Three-phase AC: 11 to 22 kW, charging at 60 to 100 km per hour.
• DC fast charger: 30 to 480 kW, charging up to 400 km per hour for vehicles capable of handling that power.

A car that’s parked for eight hours receives 11 kW. A car that’s parked for 30 minutes receives 150 kW or more. In between, the greatest gains come from smart control, not from more power.

Ten 22-kW charging stations draw a combined total of 220 kW. Most small and medium-sized businesses have a 63- to 160-A connection, which would then be maxed out all at once. Dynamic load management measures the building’s power consumption at the main connection and distributes the remaining power among the charging points. When cars are added, the power per charging point decreases; when one leaves, it increases again. This allows you to install a full charging station using the existing connection without overloading it.

The second layer is the energy management system. It connects the charging stations to the solar panels and the customer’s battery: charging using the customer’s own solar power when there is a surplus, charging from the battery during peak hours, and drawing power from the grid when the price is low. Since the capacity rate was introduced, every quarter-hour counts: a charging station that starts charging uncontrolled at 5 p.m. sets the monthly peak for the entire company.

Three rules govern the design of charging infrastructure for non-residential buildings.

• New construction and major renovations with more than 10 parking spaces: at least 2 charging points must be operational, and 1 in 4 parking spaces must be pre-wired. Pre-wiring during the structural phase costs a fraction of what the groundwork would cost later; cabling is the largest expense in a retrofit.
• Existing non-residential buildings with more than 20 parking spaces: at least 2 charging stations as of January 1, 2025.
• Installation and inspection: A licensed electrician installs the charging station in accordance with AREI standards; a certified inspection agency inspects the installation; and then you register the charging station with Fluvius.

The European EPBD-IV further tightens the pre-cabling requirement starting in 2026; we are monitoring its implementation in Flemish regulations and adapting the design of the charging infrastructure accordingly.

The investment depends on the power capacity, the cabling, and the control system. Here are three approximate figures from our projects, excluding VAT:

• 11-kW AC wallbox, installed and inspected: 1,500 to 2,500 euros per charging point.
• Charging station with 10 AC charging points, including load management and cabling: 15,000 to 40,000 euros, with the cost of groundwork accounting for the difference.
• DC fast chargers starting at 30 kW: starting at 15,000 euros per charging point, with prices increasing based on power output and grid connection.

Tax-related: The increased expense deduction for publicly accessible smart charging stations (200%, then 150%) expired on August 31, 2024. Since then, the standard depreciation rules for corporations have applied; a charging station therefore remains deductible, but without the increased deduction. We do not list fixed prices for the SCU chargers on this page; we provide those on a project-by-project basis in a quote.

A charging station in a company parking lot sits idle in the evenings and on weekends. If you open the charging stations to the public via a CPO platform, the customer earns revenue from every charging session by non-employees, and the utilization rate increases. Publicly accessible charging infrastructure requires payment via a charging card or app, a kWh-calibrated meter per charging point, and a clearly displayed rate. The SCU chargers support OCPP and integrate with the standard Belgian CPO platforms; we coordinate the configuration with the platform prior to delivery.

On a sunny day, a business with a 100 kWp rooftop system feeds tens of kWh into the grid at a low or negative price. A charging station with ten cars draws that same energy. With PV control, the wallbox charges using the surplus; with a battery in between, the customer can also charge in the evening using their own solar power. You control those three components—solar panels, battery, and charging stations—from a single EMS. An indoor battery system or a battery cabinet from Frax connects directly to it.

Please send us the number of parking spaces, the vehicles’ parking duration, and your customer’s electrical connection. We’ll create the charging plan, determine the specifications for the charging stations and any batteries, and prepare the grid study and the Fluvius application.
