Schunk Smart Charging

Always well connected



Innovative. Process-efficient. Functionally reliable.

Schunk Smart Charging - our unique portfolio of charging solutions based on pantograph technology that can be individually tailored and optimally integrated into your existing infrastructure. Whether e-bus, e-truck or electric-autonomous vehicles at ports, airports and in mines - we offer charging technologies and components that set standards.


Roof-mounted Pantograph SLS 102 / 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

Your requirements and circumstances form the framework for us

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.


Depot Charger SLS 301

Depot charging with automated current collectors enables vehicles of different heights to be docked in the vehicle depot within seconds. The charging process happens overnight, so there is no need for large amounts of electricity to flow in a short time. The product is therefore particularly compact and cost-efficient.

Charging Time: gentle continuous charging
Charging Power: 200 kW (higher charging power available on request)
Set-Up Principle: "Top-Down"
Charging Concept: Depot Charging and Opportunity Charging

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

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.

 

 


Easy adaptation to existing systems

Current Rail Interface

High power transmission and flat counter contact on the vehicle roof.
- 4 pole system
- Constant contact force distribution on all four busbars
- Compensation of vehicle movements during reloading

Cover Interface

High compensation of parking tolerances of the vehicle at the stop, high power transmission, ideal for use of special vehicles.
- 4-pole system
- constant contact force distribution on all four contacts
- compensation of vehicle movements during reloading (up to 5° including kneeling)

Funnel Interface

High power transmission, compact counter-contact, counter contact can be integrated into battery system (offers space saving on vehicle roof).
- 4 pole system
- constant contact force distribution on all four contacts
- Compensation of vehicle movements during recharging


Underbody Charger System

With the development of the underbody solution, Schunk Transit Systems enables charging both at a public charging station and in the garage at home. No more charging cable and plug - the car is positioned exactly above the charging station and charged autonomously. This is made possible by a charging station that can be retracted into the roadway, the interface built into the vehicle floor, and the extremely high power transmission.

Charging Time: from a few minutes to a few hours
Charging Power: up to 1 MW in the public area and according to the limitation of the house connection in the private area
Set-Up Principle: charging station retractable into the road + interface built into the vehicle floor
Charging Concept: Opportunity Charging, Flash Charging and Depot Charging

"For us as a manufacturer of charging solutions, it's great to see how Krakow is investing in electromobility in public transport, how the infrastructure is growing historically and how our system has become established," says Timo Staubach. But it's not just in Krakow that Schunk technology has proven its worth in helping electric buses get new energy. Worldwide, electric buses equipped with pantographs from Central Hesse operate in more than 100 cities in 25 countries. Thereby, "Smart Charging" solutions for the most diverse customer requirements are in use.
