We provide solutions for supplying power to fast chargers for electric vehicles. These may be installed in commercial fast-charging stations along the roadside, or in bus depots or truck centers. Smaller fast chargers often only need to be connected to a small substation, while a solution that enables several buses to be charged at the same time requires larger switchgear and possibly a battery bank to handle peaks in consumption. A big car park for visitors to a shopping mall or a company can be equipped with charging poles which require an enhanced power supply.
