Short answer: An overhead or roof-mounted charging system for electric buses and trucks, using an automated arm that connects without driver intervention.
Explanation
Pantograph charging uses an automated mechanical arm that either descends from an overhead structure (inverted pantograph) or rises from the roof of the vehicle (roof-mounted pantograph) to make a high-power electrical connection. This system is primarily used for electric buses at bus stops and depots, where fast, automated charging without driver intervention is essential.
The advantage of pantograph charging is automation. A bus pulls into its stop, the pantograph connects automatically, and high-power charging begins for the duration of the stop (often 3-10 minutes). This opportunity charging model lets buses with smaller batteries run all-day routes by topping up at terminus stops.
As a passenger car driver, you will not encounter pantograph charging. It is designed for commercial vehicles, particularly urban buses. But it is part of the broader EV charging ecosystem and helps electrify public transport, which reduces emissions and improves air quality in cities.

Common confusion
Pantograph charging is not related to CCS or NACS connectors. It is a completely separate system designed for buses and trucks, using a different physical connection method.
Example
Electric buses in cities like Geneva and Gothenburg use pantograph charging at terminus stops, adding enough energy in 5-7 minutes to complete the next route segment.
