Vehicle to Depot
Heavy-duty vehicles require larger batteries and thus longer charging times. SCALE will implement a charging solution with local battery storage to increase charging speeds without costly grid reinforcements. Cost reductions can be achieved by using smart charging and V2X services to enable load balancing services and reduce peak loads on the power system.
There are three use cases in this cluster:
1 - Oslo
Station-based Serviced Office B2B car-sharing with demand side management
Context
Mustad Eiendom is a property owner in Oslo that owns a shopping mall, a waterfall with power production and office spaces at the pilot site. The challenge of this use case is linked to the operational cost for the landlord to supply EV charging to all the tenants. They are currently operating approximately 150 AC charging stations and are looking for ways to reduce costs and increase user charging experience. By using smart charging and V2G, they could lower the peak demand and the load curve should align (inverted) with local production and energy prices.
Specifics
168 AC chargers uni directional 22 kW
2 Bidirectional AC chargers 22 kW
Objectives
- Reduce complexity for the driver for billing and authorisation (plug & charge).
- Increase usability by integrating the control mechanism interface with the fleet management system.
- Reduce grid fees and generate revenue from flexibility.
- Find a business model for V2G that includes EV drivers.

2 - Eindhoven
DC high power highway charging system with local RE generation & storage
Context
Heavy-duty charging infrastructure on European highways is almost completely missing and not adapted to the specific needs, power demands and sizes of parking spaces of these types of vehicles.
This use case will take place at the VDL DC Charging Test Centre Valkenswaard in the greater Eindhoven region (NL). It will focus on the simulation of the optimal set-up for highway DC High Power charging for long-haul e-coaches and other heavy-duty EVs. The simulations of high-power smart charging models, cloud services and communication protocols will support the compliance of OEMs to the latest standards and market demands.
Heavy Duty EVs are used by professional transport operators. Therefore, reducing charging time and (online) pre-booking services as part of their fleet management systems is essential for correct trip planning and avoiding high operational costs. The development of high-power smart charging infrastructure for long-haul EV transport across Europe is essential to ensure social acceptance of electrified coaches.
Specifics
3 150 kW DC V2X chargers, local renewable energy generation and stationary batteries
Objectives
- Increase charging power without grid reinforcements through stationary batteries.
- Finding optimal setup of future highway high power charging infrastructure for heavy duty vehicles through simulation. Considering customer expectations, charging on demand, predicted (dynamic) charging time and pre booking.

3 - Eindhoven
Virtual power plant at heavy-duty depot with renewable energy generation and second life battery storage
Context
At VDL’s Charging Test Centre Valkenswaard, energy management and costs optimisation of a large charging centers or logistic depots will be tested. The focus will be to test a high independency from the grid during high-power DC charging of large EVs through a Virtual Power Plant with renewable energy (solar energy buffered in a large BESS) and simulate smart charging of multiple EVs and V2X. There will also be tests in reusing batteries of EVs into BESS applications.
Specifics
4 charging points, heavy-duty vehicles
Objectives
- Reduce costs through independency to the grid, enabled by a virtual power plant with renewable energy generation, local battery storage and smart charging and V2X. This reduces costs by increased utilisation rate of renewable energy generated and by giving used battery packs a second life as stationary storage.
