DC FAST CHARGING: FASTER AND FARTHER
Build high-power charging infrastructure quicker with uncomplicatedand robust designs

As the world transitions towards
sustainable transportation, the demand for
efficient and rapid electric vehicle (EV)charging solutions has never been greater.
With an ever-growing number of EVs on
the road, more charging stations areneeded to sufficiently cover the vast road
network and overcome a major consumer
concern of range anxiety. 

This means that charging infrastructure producers andinstallers need efficient designs and easy-to-install systems
to fulfill the market needs. Another hindrance on the path towider EV adoption is charging time. The only way to becompetitive with the convenience of fueling traditional
internal combustion engine vehicles is to deploy more
publicly available fast charging stations. 

These require next-generation designs with higher power
throughput to match the increasing demand for battery
capacity and customer expectations for charging times.
Crucial in this regard are component power capability, lessheat loss and greater efficiency. With this rising market
pressure, the charging infrastructure is being put undermore stress, so robustness becomes a key characteristic ofany design, as it ensures maximum system operation timeand lower maintenance costs.
