Roof Mounted Pantograph SLS 102 & SLS 103

The compact roof-mounted pantographs SLS 102 and SLS 103  are mounted on the roof of the e-bus and operate on the "bus-up" principle: the bus stops under the charging station, where the roof-mounted pantograph extends, connects to the charging station and charges the batteries.

Charging Time: from 30 seconds to overnight charging
Charging Power: from 150 kW up to 1 MW
Set-Up Principle: "Bus-Up"
Charging Concept: opportunity charging, flash charging and depot charging

The advantages of our SLS 103 and SLS 102 roof-mounted pantographs have already proven themselves in many projects all over the world. The compact pantographs are mounted on the roof of the E-bus or battery-powered industrial vehicle and function according to the bus-up principle: The vehicle stops under the charging station where the roof charging pantograph extends, connects to the charging station and charges the batteries. Charging can take place both in the depot and during operation at a charging station within the route network - without any delay to regular driving operations. This is guaranteed by the extremely fast contacting and the very high current transmission. Our patented contact systems can be adapted to a variety of vehicles and specific customer requirements.

You benefit from these advantages:

  • SLS 102: Precisely designed to meet customer requirements for power transmission and availability; contacting in only four seconds or < 1 second if required
  • SLS 103: A technological milestone that sets previously unattained standards; charging electric vehicles of various heights up to double-decker buses in seconds - with a single charging current collector and very high performance
  • Integration on the battery-powered vehicle - contacting with charging infrastructure according to the bus-up principle
  • Multipole concept (minimum 4 poles) and contact sequence for safe charging
  • Precise compensation of parking deviations and kneeling effects during the loading process

Contact Systems

Depending on the framework conditions, different contact units can be used. The existing infrastructure can be used. Even different power grids do not pose a problem. We offer the following contact systems: 2-, 3-, 4- and 5-pole. Currently, the most commonly used solutions are the 4-pole and 5-pole current collectors. The system meets the requirements of standardization according to EN 50696.

Compensation of Parking Tolerances

With our drive mechanisms, we offer fast and efficient reloading - in any road conditions. This compensates for vehicle movements during reloading as well as parking tolerances.

  • ± 500 mm in the direction of travel
  • +/- 250 mm parallel to the direction of travel
  • 4° Kneeling

Current Transmission

To achieve an ideal balance between battery size, passenger load and range, you need a functionally reliable and high power transfer in a few seconds. The following power transfers are possible:

  •  Pulse charging: 1 MW for 30 s
  •  Opportunity charging: 500 A for 15 min
  •  Depot charging: 150 kW continuous current

All charging possibilities can be carried out with one system.
