Fast EV charging - Integrated storage and EV charging solutions

Fast charging of EVs is increasingly creating stress on the electricity grid. Addressing this requires a combination of capacity upgrades and (temporary) energy storage solutions. While upgrades are often costly and take years to realise, storage solutions can be mobilised today.

Alfen’s fully integrated storage and fast EV charging solution is ‘plug and play’, allowing it to be rapidly deployed to provide new or additional charging capacity at various locations. Offering maximum flexibility it can be relocated, as desired, to any site with an immediate demand for fast EV charging.

Alfen combines its energy storage system and smart grid experience to equip fast charging stations with peak shaving capability. Business cases can be further improved by using the storage for energy trading when capacity is not being fully utilised for EV charging solutions.

Increasingly, hubs with a large number of EV chargers grouped together are being deployed in locations such as offices, shopping malls, stadiums, parking garages and exhibition centres. The simultaneous charging of multiple EVs this way puts significant pressure on the local electricity grid connection because it increases peak loads.

Alfen’s EV charging equipment can help to mitigate this through load balancing, with chargers connected in a network and real time available power capacity distributed optimally across all EVs charging at any one time. The additional integration of an Alfen energy storage system allows full mitigation of peak loads, allowing maximum output at each charging point, and storage, and optimal consumption of, locally generated renewable energy.
