Samenvatting

With a low-/no-emission zone coming into effect in Amsterdam city centre, Albert Heijn must switch to electric delivery vans to if it is to continue its grocery delivery service to customers’ doors. Albert Heijn intends to scale up to 750 delivery vans in the 4 large cities in the coming years [1], meaning the Amsterdam depot can expect up to 200 vans. When considering the congested grid that grips the Netherlands and the increased demand for new and larger grid connections, charging this fleet of electric vehicles is no easy or cheap task. The Accelerating Zero Emission Delivery (AZED) project aims to better inform Albert Heijn on how to charge their delivery vans in a grid congested environment through the use of a stationary battery energy storage system (BESS). The Albert Heijn distribution centre in Amsterdam is connected to the grid via a substation with a capacity of 6000 kVA. The substation feeds three transformers with a nominal capacity of 2000 kVA each. The current pilot project installed at the Amsterdam Albert Heijn distribution centre consists of 36 charging stations; 33 x dual 22 kWAC, thus 66 connections of 11 kWAC, and 3 x 50 kWDC chargers. The charging stations are connected behind one of these three transformers. With all the charging stations used simultaneously at their nominal power, the power requested from the transformer is 876 kVA (assuming a power factor of 1). More charging stations will be connected as the delivery truck fleet is increasingly electrified. A BESS will also be installed to reduce the peak load on the grid connection. The capacity and power of the BESS are still to be defined and is investigated in this study. In the pilot project Albert Heijn used a combination of Orten e-HDV, SAIC Maxus, Streetscooters Work L, and VW e-Crafters. However, the data provided included only the Orten and SAIC delivery vans. Table 1 presents the delivery van specifications as provided by the manufacturer specification sheets.
