A CCS2 connector is one component at the vehicle end; a CCS2 DC fast charging cable is an assembly that combines the connector, conductors, communication paths, temperature sensing where specified, jacket, strain relief and charger-side termination. Charger OEMs should source against an assembly drawing and interface definition, because a connector rating alone does not define the completed cable system.
Who is this guide for?
This guide is for DC charger manufacturers, engineering procurement teams and service integrators deciding whether they need a component, a cable assembly or a customized integration. The decision affects drawings, termination work, validation responsibility and change control. It should be clear before suppliers quote.
Where does the connector end and the cable assembly begin?
The CCS2 vehicle connector provides the mechanical and electrical interface to the vehicle inlet. The cable assembly adds the conductors and signal paths, cable construction, sensing arrangement when applicable, strain relief, outer jacket and charger-side termination. A complete assembly may reduce integration work, but only when its interfaces match the charger design and validation plan.
Decision table
| RFQ field | CCS2 connector component | CCS2 cable assembly |
|---|---|---|
| Purchase scope | Vehicle-end component | Connector plus defined cable and termination |
| Buyer responsibility | Cable design, assembly and validation | Charger integration and system validation |
| Key drawing | Connector interface and termination | Full assembly drawing and pin/termination map |
| Thermal evidence | Component conditions | Assembly and system conditions |
| Change control | Connector materials and revision | Connector, cable, sensor and termination revision |
What determines the correct purchase scope?
Review what the charger factory can assemble and validate in house. If the team already controls conductor preparation, crimping, sealing, sensing and termination, a component purchase may fit the process. If it needs a ready cable assembly, the RFQ should define length, current class, cooling approach, sensing, charger-side interface, bend and installation constraints, and the required documentation. Neither route removes the need for system validation.
What information belongs in the RFQ?
State the charger platform, target market, connector standard and version, intended current and voltage class, duty profile, cooling approach, cable length, environmental conditions and charger-side termination. Add the communication and interlock mapping, temperature-sensing requirement, drawing format, sample quantity and validation plan. Values must come from the project specification; do not borrow ratings from another assembly.
What evidence should engineering request?
Request controlled drawings, bill-of-material or configuration identification, terminal and sensor information, material declarations needed by the project, inspection records and test evidence tied to the quoted version. Confirm how the supplier records connector, cable and termination revisions. For samples, photograph both ends, labels, cable marking and the charger-side termination before installation.
Common integration mistakes
Teams sometimes approve the connector appearance while leaving the charger-side termination open. Another mistake is transferring a headline current rating into a different cable length, ambient condition or cooling design. Temperature sensing also needs a defined location, signal interface and response within the charger control system. Treat every rating as conditional on the stated model and test setup.
Sample and incoming checklist
- Match assembly model, drawing and revision
- Check connector housing, contact area and locking features
- Confirm cable marking, length and jacket condition
- Verify sensor and communication mapping against the drawing
- Inspect strain relief and charger-side termination
- Run fit and controlled system validation with qualified personnel
- Record results against the sample serial or batch identity

FAQ
Is a CCS2 connector the same product as a CCS2 cable?
No. The connector is a component; the cable assembly adds cable construction, sensing where specified and charger-side termination.
Does a connector current rating define the whole assembly?
No. The completed system depends on the connector, conductor, cable, cooling, ambient conditions, duty profile and charger controls.
Can a cable assembly be approved from photos?
No. Photos support identity checks, but controlled drawings and system validation are still required.
