CCS2 Standard

Compatibility / DC and AC interface

CCS2 is an interface ecosystem – not a universal promise between every vehicle and charger.

CCS2 combines the Type 2 AC geometry with additional DC contacts for combined charging. Adapter selection depends on the connector direction, charging mode and communication route.

Standard overview

CCS2 Charging Standard Compatibility

CCS2 is widely used for DC fast charging in Europe and other CCS2-oriented markets, while the Type 2 portion supports AC configurations. A CCS2 station cable and a vehicle with another standard need more than a shape conversion when DC communication differs.

What this page can answer

  • Whether the requirement appears to be AC or DC
  • Which connector direction should be investigated
  • Which product family is relevant to that direction
  • Which vehicle and station details remain necessary

What it cannot confirm alone

  • Compatibility with every vehicle or charger
  • A guaranteed real-world charging power
  • Charging-network access or payment eligibility
  • Model-specific certification without document mapping
Do not use a CCS2-to-GB/T DC adapter as an AC adapter, and do not assume it supports every CCS2 station or every GB/T vehicle.

Direction map

Read the route from charging source to vehicle

Route A

CCS2 station connector -> GB/T DC vehicle

Confirm the source connector, vehicle inlet and charging mode, then review the product and communication requirements.

CCS2 to GB/T DC adapter →

Route B

CCS2 station connector -> compatible CCS2 vehicle

Use the native interface where possible. If a different source or vehicle inlet is involved, record both ends before choosing a product.

No adapter is normally required →

Compatibility decision

Six checks before hardware selection

Check Question Why it matters
1. Market version Where was the vehicle originally sold? Vehicles sharing a badge can use market-specific inlets and software.
2. Vehicle inlet What is physically installed on this exact vehicle? Confirms the receiving interface and prevents reversed adapter selection.
3. Charging source What connector is on the cable or station? Defines the source side and the adapter direction.
4. Charging mode Is the intended session AC or DC? AC and DC routes are not interchangeable.
5. Communication What vehicle, station and software combination is involved? A physical match alone does not validate the charging handshake.
6. Evidence status Has this combination been reviewed or field-tested? Keeps confirmed, conditional and unverified combinations clearly separated.

Performance boundary

Adapter rating and actual charging are different values

The adapter or connector rating describes the product’s maximum designed operating envelope. The charging session is negotiated and limited by the vehicle, BMS, charger, cable, temperature, state of charge and software. Use the lowest applicable system limit and treat unverified combinations as requiring manual review.

Vehicle limit

Onboard charger or DC charge curve, battery temperature, state of charge and software.

Station limit

Available voltage, current, cable capability, station model, firmware and site power.

Adapter limit

Model-specific voltage, current, thermal, ingress and control specifications in the applicable documentation.

FAQ

Interface questions

Is connector fit enough to confirm compatibility?

No. Charging mode, communication, vehicle version, station model and software can all affect the result.

Can an adapter increase the vehicle’s charging power?

No. It cannot override the vehicle, battery or station limits. The lowest applicable system limit controls the session.

How do I confirm the direction?

Name the connector coming from the charging source first and the vehicle inlet second, then state whether the requirement is AC or DC.

What evidence should I send?

Send the vehicle model and year, original market, inlet photo, charger connector and label, required charging mode, and any error code or session video.

Map both ends before choosing the adapter.

Send a clear vehicle-inlet photo and the connector or label from the charger. We will identify the relevant product route and flag combinations that still require manual validation.
