Siemens is launching the e-Line OnBoard collection, a very quiet charging pantograph for electrical buses, appropriate for charging powers of as much as 600 kW. The pantograph charger can be utilized for infrequent charging for a short while with excessive currents or for charging on the depot with decrease currents.
That stated, the system is extra prone to discover its most helpful utility away from the depot, the place residents might react sensitively to charging noise. In accordance with Siemens, the brand new pantograph is characterised by very low noise growth when contacting the charging bonnet and reducing onto the bus roof. In accordance with the producer, that is achieved by a particular design and noise-absorbing coupling parts to the charging head. Siemens claims the machine has the quietest contact build-up in its class with a noise stage peak of 54 dB at a distance of ten metres.
Though the pantograph now helps as much as 600 kW, the German engineering agency says the transmission of even increased charging currents is deliberate as a growth step within the close to future. The pantograph e-Line OnBoard collection is claimed to attain with an unladen weight of lower than 90 kilograms, a “wear-resistant design”, and an optionally accessible self-lowering operate.
The charging pantograph has a mechanical interface of 600 x 630 mm set up dimensions, making it mechanically appropriate with bus set up with present roof pantographs. Outfitted with the brand new Siemens charging pantograph, electrical buses can nonetheless cost on the similar relative place to the charging station, which implies already present markings don’t essentially must be modified, explains Siemens.
Assessments and subject trials have already been accomplished, with Siemens saying that the pantograph is prepared for collection manufacturing, complies with EN 50696 in all elements and can be utilized with as we speak’s commonplace charging bonnets.
