Inverted Pantograph SLS 201

The SLS 201 inverted pantograph is integrated on the infrastructure side at a central location, for example the bus depot or within the route network. Its contacting works according to the top-down principle: The bus parks under the inverted pantograph, which moves down, connects with the counterpart on the bus roof and charges the batteries.

Charging Time: from 30 seconds to overnight charge
Charging Power: up to 600 kW
Set-Up Principle: "Top-Down"
Charging Concept: Opportunity Charging, Flash Charging and Depot Charging

Our inverted pantograph SLS 201 is the worldwide proven standard for flexible, fast and safe charging of e-buses and battery-powered industrial vehicles. Our patented contact systems can also be adapted to other vehicles and specific customer requirements. The inverted pantograph is integrated on the infrastructure side at a central location where its contacting functions according to the top-down principle: The vehicle parks underneath the inverted pantograph, the latter drives down, connects to its compact counterpart on the vehicle roof and charges the batteries. This system guarantees a safe current transmission of up to 1,000 A via a multipole concept and maintains a defined contact sequence during contacting.

You benefit from these advantages:

Integration into the charging infrastructure - contacting with battery-powered vehicle according to the "top-down" principle
Enables different types of vehicles (single and double-decker buses) at a strategic location with a single charging current collector
Fast contacting in only 5 seconds
Multipole concept (minimum 4 poles) and mechanical contact sequence for safe charging
Precise compensation of parking deviations and kneeling effects (+/-5°) during the charging process without charging interruptions
High power transmission in a few seconds

Drive Systems

New standards by advanced and patented drive system

Our product has an extremely high number of cycles (> 400,000 cycles). The system enables contacting within five seconds and ensures that there is no loss of contact during the loading process. The combination of spring and drive system guarantees a constant contact force over the entire working range of the pantograph during the loading process. A built-in fail-safe function automatically returns the pantograph to the rest position in the event of a power failure or fault.

Operating Range

The half-scissor design of the inverted pantograph makes it possible to recharge different vehicles at one bus stop or charging station

The flexible system enables reloading of conventional and double-decker buses (the maximum deflection is approx. 2.3 meters) as well as special vehicles at the same stop. The inverted pantograph also automatically compensates for vehicle movements during reloading.
