Allego was looking to develop their motorway network and had identified two sites in Kircheim, Germany, and then in Wanlin, Belgium. Capacity management was the critical consideration of both projects, due to the isolated nature of the sites. Both sites suffered from grid constraints and the company wished to explore the use of battery storage to ensure that the introduction of rapid chargers did not cause the grid constraint to be exceeded.
As the usage of EV’s becomes even more pronounced, faster charging stations will be required to deal with the capacity, with a greater requirement for BESS to make up for the increased grid usage, otherwise companies will be required to invest in extremely costly grid upgrades.
EV rapid chargers require a lot of power, many current systems require 50kW whilst 150kW and 300kW+ chargers are now more commonplace. Providing sufficient power for expanding clusters of these systems to operate will become an increasing challenge and part of the solution will inevitably be energy storage.
