Yes, in general.
As of September 2026, EU charging rules do not impose a blanket ban on using a CCS to CHAdeMO adapter. A compatible adapter can therefore be used to charge a CHAdeMO car from a CCS2 fast charger, provided the product complies with the applicable safety requirements and the charging station operator allows its use.
The situation is slightly more nuanced than simply asking whether adapters are legal. Product safety, charger compatibility and the charging operator’s own rules are separate issues.
Is there an EU law that bans CCS to CHAdeMO adapters?
No EU-wide rule specifically prohibits CCS to CHAdeMO adapters.
The EU’s Alternative Fuels Infrastructure Regulation, usually called AFIR, sets requirements for public charging infrastructure, interoperability, payment and charger availability. It also establishes CCS Combo 2 as the standard connector for new or renovated public DC charging points for light-duty vehicles.
The regulation does not say that an older CHAdeMO vehicle may only charge from a native CHAdeMO connector or prohibit the use of an active adapter between the vehicle and a CCS charger.
For European CHAdeMO owners, the relevant product is normally a CCS2 to CHAdeMO adapter.
Does the adapter itself need to meet EU safety requirements?
Yes.
Electrical products sold to consumers in the EU are subject to product safety legislation. The General Product Safety Regulation requires economic operators to place only safe products on the EU market and specifically considers the intended use of a product and its foreseeable interaction with other products.
Depending on the product and its electrical characteristics, other EU legislation can also apply. For example, the Low Voltage Directive covers electrical equipment designed for certain AC and DC voltage ranges and sets safety requirements for such equipment.
For the driver, the practical point is simple: use an adapter intended for the voltage, current, connector type and vehicle involved.
Does a CCS to CHAdeMO adapter need CE marking?
Applicable EU legislation determines whether CE marking is required for a particular product.
A CE mark is the manufacturer’s declaration that the product conforms to the EU requirements that apply to it. It is not a separate approval or safety certificate issued by the European Union.
The Longood CCS2 to CHAdeMO adapter sold by Autonlaturit.com is CE marked. It is rated for up to 1,000 V and 200 A and has an IP54 enclosure rating.
CE marking should not be the only thing you check when comparing adapters. Confirmed vehicle compatibility, electrical ratings, firmware support, clear instructions and support from the seller are also important.
Can a charging network prohibit adapter use?
Potentially, yes.
Something can be legal to own and use generally while still being restricted by the terms of a particular charging service.
Charging stations are operated by private companies, and users have to follow the operator’s terms and technical requirements. An operator may restrict unsupported vehicles, connectors or third-party equipment even if the equipment itself is legally sold in Europe.
Technical compatibility can create a similar limitation. A CCS charger may refuse to start a session if its software does not accept the communication it receives through an adapter.
Before depending on a particular network, you can check whether the operator has published any restrictions on using adapters. However, we are not aware of any charging network in Europe that currently prohibits the use of a compatible CCS2 to CHAdeMO adapter.
Does public charging law guarantee that an adapter will work?
No.
EU rules require public charging infrastructure to meet interoperability standards, but that does not create a guarantee that every third-party adapter will work at every CCS charger.
CCS chargers use hardware and software from different manufacturers. Firmware updates, charger configuration and network-specific authentication can all affect a charging session.
The Longood adapter sold by Autonlaturit.com has been field-tested with CCS equipment from manufacturers and networks including ABB, Kempower, Alpitronic, Tritium and Ionity. Its firmware can also be updated through USB.
Testing the adapter at chargers near home before relying on it during a long trip is still worthwhile.
Does using an adapter modify the car?
A CCS to CHAdeMO adapter is an external charging device. It connects to the existing CHAdeMO inlet during charging and is removed afterwards.
It does not require replacing the vehicle’s charging port or permanently converting the vehicle from CHAdeMO to CCS.
Is it legal to use the adapter with a very powerful CCS charger?
The charger’s headline power rating does not make the adapter illegal or automatically send that amount of power into the car.
During DC fast charging, the car communicates how much voltage and current it is prepared to accept. A 300 kW CCS charger does not force a 40 or 50 kW CHAdeMO car to accept 300 kW.
The adapter must still be rated appropriately for the charging system being used. The Longood CCS2 to CHAdeMO adapter is specified for up to 1,000 V and 200 A.
The vehicle remains responsible for its own charging limits.
Can you use the same adapter everywhere in Europe?
European public DC charging is centred around CCS2. Under the current AFIR technical specifications, new or renovated public DC charging points for light-duty vehicles must provide Combo 2 for interoperability.
That makes CCS2 to CHAdeMO the relevant adapter type for most European driving.
However, Europe is not a single legal jurisdiction. EU regulations apply within the EU, while countries outside the EU can have their own product, electrical and consumer rules.
If you are travelling outside the EU, particularly with an adapter purchased from another market, check the local requirements and the connector type used by the charging network.
What should you check before using an adapter?
Start with the product itself.
Make sure the adapter is intended for CCS2 to CHAdeMO DC charging, is electrically rated for the application and is confirmed to work with your vehicle.
Inspect the connectors and housing before charging. Do not use damaged equipment, and follow the manufacturer’s current connection and disconnection instructions.
For an active adapter, firmware support is also useful because public chargers continue to receive software updates.
Bottom line
Using a CCS to CHAdeMO adapter is generally legal in the European Union. There is no EU-wide rule banning a compatible adapter from being used to connect a CHAdeMO vehicle to a CCS2 fast charger.
The adapter itself must comply with the product safety rules that apply to it, and drivers must follow the requirements of the charging station operator.
A legal product is not automatically compatible with every car or every charger. Check the vehicle, adapter specifications and charging network before use.
For CHAdeMO drivers using a compatible vehicle, a properly designed CCS2 to CHAdeMO adapter provides a legal way to access the CCS charging infrastructure that now forms the backbone of European public fast charging.
