More and more electric vehicle (EV) charging points are sprouting up along
highways, byways and driveways. As availability becomes less of an issue,
EV owners are starting to look closer at this equipment‘s reliability and the
energy costs associated with charging. Equipment vendors have to respond.
The commercial charger stations are connected directly to a public
medium-voltage distribution network via a low frequency transformer, which
increases power levels to 300 kW and beyond. In this case, more electrical
power can mean faster charging.
A stationary charger unit typically consists of the power electronics, control
circuitry, communication with the BMS (battery management system), and
the user interface. Power electronics, in turn, consist of two parts, PFC (power
factor correction) and the DC/DC converter.
