A charging technology for electric commercial vehicles: conductive charging is understood as energy transfer via a cable and/or contact. Appropriate standardisation is in place and has been anchored in standards to ensure charging compatibility. The ISO standards IEC 61851 and IEC 62196 stipulate AC and DC charging procedures. There are efforts to adopt the CCS (combined charging system) standard for conductive charging in the commercial vehicle sector, as is already the case for passenger cars. This is a combined charging procedure (communication exclusively between charging connector and socket). This means, for example, that the same charging interface with a lower output can be used to charge overnight at a household AC supply as on the road at a quick charging column using DC procedures and high output. The urban bus sector faces the special requirement for automated conductive charging of electric buses during service. The most promising is the charging procedure via pantograph. This involves a contact system rising from the charging station or from the vehicle to its counterpart, thus providing a fixed electrical connection. The alternative to conductive charging is Inductive Charging.
