Pantograph charger

A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line.It lift or down on the basis of the wire tension. Typically a single wire is used with the return current running through the track.

Pantograph charging is a method of charging electric buses in depots or at specific charging stations through an inverted pantograph that is mounted on a gantry or mast. In a depot setting, buses are parked under overhead charging stations with a pantograph mounted on a rigid arm.

In a depot setting, buses are parked under overhead charging stations with a pantograph mounted on a rigid arm. The pantograph is lowered on to the bus’s roof-mounted charging receiver, allowing for a fast and efficient charging process. Alternatively, pantograph charging can also be used as opportunity charging along a route, with the charging stations installed at bus stops or other key locations where buses can briefly stop and recharge.

NASN charger support pantograph charging systems.
