Efficient use of charging station

WattHub, an initiative by a construction consortium of 3 parties (Dura Vermeer, Ploegam and Van Oord) and the 'Burgerwindcoöperatie West-Betuwe', is the first and largest charging station for electric trucks and construction equipment in the world. The charging station along the A15 near Geldermalsen provides a solution to power all sustainably driven construction equipment used in the dike reinforcement project 'Mekante Diek.' Label A developed a unique digital reservation tool that enables efficient use of the charging station, allowing continuous work on the construction site with charged equipment.

Building an optimally functioning solution

The idea for Watthub emerged in early 2021 when the dike reinforcement project between Tiel and Waardenburg was awarded to the Mekante Diek construction consortium. One condition was to execute this project completely emission-free. The infrastructure for charging large equipment and trucks did not exist, so the Mekante Diek consortium decided to collaborate to develop it themselves. Initially for their own use, but since October 1, 2023, Watthub has also been accessible to Watthub's customers

After a selection process, Label A was chosen to develop the complex reservation tool for Watthub. With clients like Van Oord, EV box, Check and Spotten (Dura Vermeer), Label A also has a proven track record in the construction, mobility and energy markets; this was a significant factor for Watthub in selecting the right partner. Our experience in developing complex custom software and our approach to translating Watthub's needs into the right solution were crucial in this decision.

The Product Owner of Watthub had a broad understanding of the platform's operation and functionalities, but translating this into an optimally functioning solution in close collaboration is precisely what Label A's process is designed for. Based on Watthub's needs, end-user input, feedback, testing and workshops, we developed the ideal tool.

Streamlined coordination for maximum efficiency.

Charging construction equipment is a business-critical process. Waiting and charging times must be minimized to achieve maximum efficiency. By conducting interviews with end-users, we gained a good understanding of usage and workflows. These insights, obtained through user research, later proved essential in developing the reservation tool.

"For Watthub, a stable, scalable reservation system is crucial. It is the missing link between all existing third-party software. Additionally, we can facilitate software that does not yet exist. Together with Label A, we have designed and realized the perfect software for Watthub. This solution enables us to meet our customer's needs and provides us with the scalability to easily grow in the future. Label A is a great partner to work with,"

From charging stress to charging certainty

With a (business) account, a Watthub customer can easily reserve a charging spot in the reservation tool, ensuring 100% certainty of fast charging without waiting times, in the desired time slot. The tool is also very user-friendly for Watthub location planners. They can consult the schedule of the entire charging station and make adjustments through a clear dashboard. This allows Watthub to provide charging certainty for all contractors and their equipment on the construction site, as well as external customers using the charging station.
