with Schunk Smart Charging

Conductive charging systems overview: bus-up, top-down, depot, and underbody

SLS 104 – new roof-mounted pantograph with extended working range

The new SLS 104 combines the compact form factor of the SLS 102 with the long reach of the SLS 103. Ideal for mixed-use fleets, it enables reliable automatic charging across a wide range of vehicle heights and is fully backward-compatible with existing infrastructure.

• Extended vertical reach up to 2,000 mm
• Optimized for vertical contact – no resting device needed
• Intelligent drive system

• Future-proofed for up to 1,000 A continuous current

SLS 102 / SLS 103 – proven roof-mounted pantographs (bus-up)

Compact, robust, and in use worldwide. The Panto is mounted on the vehicle and connects to the tailgate from below.

• Bus-mounted pantograph connects to overhead dome
• Lightning-fast contact in under 5 seconds
• Charging power up to 1 MW for double-deckers

• Actively compensates for parking misalignment

SLS 201 – inverted pantograph (top-down)

The charging element is located in the infrastructure. Perfect for central charging points and confined depot environments.

• Station-mounted pantograph contacts roof rail
• Ideal for shared stations or depots with height variations
• Vertical range up to 2.3 m
• UL certified and Buy America ready

SLS 301 – depot charger for overnight charging

Cost-effective top-down solution for overnight charging. Low weight on the vehicle, low maintenance.

• Compact, cost-effective top-down solution
• Low-maintenance design with minimal vehicle weight impact

• Used successfully in Zaragoza with 68 buses

Underbody Charger – fully automated ground-based charging

Automated charging system in the floor – developed for autonomous logistics processes.

• Installed in the road surface for autonomous operation
• Cable-free, hands-free operation
• Charging up to 1 MW in seconds

• Compliant with ISO 15118 and DIN EN 61851-23-1
