As electric vehicle battery systems become more compact and powerful, engineers face increasing pressure to optimize every millimeter of available space. ARaymond’s new Selfy® XS ultra-compact Quick Connector is designed to meet that challenge.

Designed for High-Density EV Battery Environments
Modern EV battery packs are built with tightly integrated components, leaving minimal room for fluid connections. The Selfy® XS addresses this need with an ultra-short, flat-based design that fits into spaces where standard connectors cannot.
With approximately 40% size reduction for any equivalent flow diameter compared to conventional connectors, the solution enables more efficient packaging and integration within battery systems.
By reducing connector size and weight, the Selfy® XS helps manufacturers:
- Free up space for additional battery cells
- Increase energy density
- Improve thermal management performance
- Reduce overall vehicle weight
- Extend EV driving range.
Optimized flow performance and low pressure drop further enhance cooling efficiency, supporting faster charging and improved battery longevity.
Proven Safety with Assembly Confirmation
The Selfy® XS incorporates ARaymond’s trusted Selfy® assembly confirmation technology, ensuring reliable and secure connections.
Key features include:
- Three-point confirmation of proper assembly: Visual, mechanical/tactile and audible confirmation
- Low insertion force for easier installation
- Tool-assisted disassembly
- Optional data matrix code for traceability, and to enable the detection of correct connection with a camera or other digital scanning tools
These features help reduce assembly errors while supporting quality control and compliance requirements.
Available in multiple diameters and configurations, the Selfy® XS can be tailored to meet specific application requirements. While optimized for battery cooling systems, it can also be used in other compact fluid management environments.
The Selfy® XS is eco-designed to reduce material usage and weight while increasing efficiency. It also supports alternative material options, including recycled, helping manufacturers lower their environmental impact.

See It at The Battery Show Europe
With its combination of ultra-compact design, safety features, and high performance, the Selfy® XS represents a new generation of Quick Connectors built for the future of electric mobility.
ARaymond will showcase the Selfy® XS at The Battery Show Europe, June 9–11, with live demonstrations and product experts available on site.
