ULEV Charger Types

An electric vehicle charging station, also called EV charging point, is a specialist piece of equipment that supplies electric energy for the recharging of electric vehicles, such as 100% battery electric vehicles, and plug-in hybrids.
As plug-in hybrid, electric vehicles and battery electric vehicle ownership is expanding, there is a growing need for widely distributed publicly accessible charging stations, some of which support faster charging at higher voltages and currents than are available from residential EV charging points. Many charging stations are on-street facilities provided by electric utility companies or located at retail shopping centres and operated by many private companies. These charging stations provide one or a range of heavy duty or special connectors that conform to the variety of electric charging connector standards.

 

Charging from the Infrastructure

When it comes to the connecting the vehicle to the EV charging station, there are a few ways to do so:

Conductive charging – for this form of charging there are 3 types:

 

These utilise a cable and can have a variety of connection heads.

Charging Speeds

When charging an electric vehicle, the time to charge depends on the kWs from the charging point where a kW is a measure of one thousand watts of electrical power. Typical household appliances, such as dishwashers use 1.2-1.5 kW’s, Home AC 1.0-4.0 kW’s and Electric Kettle about 1.2-3.0 kW’s.
