Electric Vehicle Supply Equipment

Electric vehicle supply equipment (EVSE) supplies electricity  to an electric vehicle (EV). Commonly called charging stations or charging docks, they provide electric power to the vehicle and use that to recharge the vehicle's batteries. EVSE systems include the electrical conductors, related equipment, software, and communications protocols that deliver energy efficiently and safely to the vehicle.



Charging Equipment

The function of the charging equipment is to transmit the burden materials through the locks in the furnace to desired locations on the burden surface in the throat. For many years, the two-bell charging system with movable armor was the only proper charging equipment but nowadays the bell-less rotating chute is dominating. The advantages of the bell-less top is the more accurate filling of the furnace and better gas tightness with higher top pressures. The stock level is measured either with a mechanical stock rod or with a radar.


Inductive charging is defined as the transfer of energy from the supply network to the vehicle in an electromagnetic way, using a two-part transformer with the primary connected to the network and the secondary installed on the vehicle. Charging can be performed after juxtaposition of the two parts.

The introduction of inductive charging systems has been proposed to allow a considerable improvement of charging safety. The nonconductive energy transfer virtually eliminates all risk of electric shock for the user. Furthermore, the opportunity for automatic connection dispenses with the use of electric cables, thus removing both electrical (handling of power connectors) and mechanical (trailing cables) hazards which are usually associated with the use of electric vehicle charging equipment.
