Скачать или смотреть Bus-Down Pantograph Charging: Schunk’s Inverted Pantograph SLS 201 | Smart Charging

With Schunk’s Inverted Pantograph SLS 201 a technology milestone in terms of bus-down pantograph charging has been set. Since the "reversed" pantograph is not mounted onto a bus roof, but rather is integrated into the existing power-transmission infrastructure (e.g. in the roadway mast of the holding station, bus station or depot), it is the ideal EV charging station solution. With this bus charger it is possible to recharge different buses at one location.

▬ Inverted pantograph ▬▬▬▬▬▬▬▬▬▬▬▬
"Our new inverted pantographs, in particular, are precisely tailored to meet our customers' needs," stated project director Timo Staubach. This "reversed" pantograph is not mounted onto a bus roof, but rather is integrated into the existing infrastructure, e.g. in the roadway mast of the holding station, bus station or depot. The current collector au-tomatically extends as soon as the bus stops underneath it and docks with the corresponding contact on the bus roof. This contact system features an open interface which is compatible with existing interfaces on the roof of the bus. Schunk also offers newly developed contact interfaces for these types of pantographs for better utilization of the installation space on bus roofs and to allow integration into the bat-tery system. The half-scissor design gives the pantograph a wide work-ing range and enables both conventional public-transport buses and double-decker buses to be charged at the same bus stop. Other appli-cations, such as use with garbage trucks and special vehicles at ports and airports, are also conceivable.


▬ On-board pantograph ▬▬▬▬▬▬▬▬▬▬▬▬
Schunk on-board pantographs (mounted on buses) also feature a spe-cially-developed four- or five-pin contact head. At the charging station this head docks with the contact hood attached to a retaining mast completely automatically. While parking and tilting toward the pas-senger entrance side of the vehicle ("kneeling") the vehicle, the rock-ing design of the pantograph compensates for angle tolerances and deviations. Thanks to this special design, the contact pressure against the charging station is maintained without interruption during all phases, regardless of the position. Pulse charging at bus stops lasts no more than 15 seconds thanks to a very high electric current transfer capacity (1,000 A). So-called opportunity charging is also feasible with this system. Here, 500 – 600 A can be transferred within a few minutes. This enables the use of smaller batteries, which allows bus operators to achieve significant savings.


▬ About the Schunk Group ▬▬▬▬▬▬▬▬▬▬▬▬
The Schunk Group is an international technology group employing around 9,100 people in 29 countries. The company is a leading supplier of products made of high-tech materials – such as carbon, technical ceramics and sintered metal – as well as machines and systems – from environmental simulation and air conditioning to ultrasonic welding and optical machines. Turnover of the Schunk Group was €1.35 bn in 2019.

The Schunk Group's long-term outlook, first held by Ludwig Schunk over 100 years ago when he founded today's Schunk Group, is crucial for its success.

According to his wishes, "the company must be led in such a way that healthy development and the preservation of independence are paramount." The Schunk Group's long-term goals of financial stability and independence, profitable growth and global presence are derived from this.

Technology leader through competence in materials and engineering.
