The Longood CCS to CHAdeMO adapter has one important advantage that many buyers do not notice at first: it is supported by independent open-source firmware development.
A CCS to CHAdeMO adapter is not just a physical connector. It is a communication device that sits between a CCS fast charger and a CHAdeMO vehicle. As charging stations, car models and charging networks evolve, the adapter’s software becomes a major part of long-term compatibility.
In practice, the Longood adapter is not dependent only on factory support. An active community can continue improving the software, fixing compatibility issues and adding useful functions over time.
For buyers, this is one of the strongest reasons to choose the Longood adapter with confidence.
The manufacturer also now ships new Longood adapters with this open-source firmware.
What does open-source firmware mean?
Open-source firmware means that the software code behind the firmware is publicly available for independent developers to inspect, improve and maintain.
For the Longood CCS to CHAdeMO adapter, this is especially valuable because the adapter has to handle communication between two different fast-charging standards. CCS chargers and CHAdeMO vehicles do not speak the same “language” directly. The adapter has to manage that communication so the charging session can start, continue and end correctly.
Because the firmware is open source, experienced developers and users can help improve how the adapter behaves with different cars and charging stations.
This is very different from a closed system where every future update depends only on the original factory.
Why does firmware matter in a CCS to CHAdeMO adapter?
A CCS to CHAdeMO adapter is not a simple plug converter.
It contains electronics and firmware that allow a CHAdeMO-equipped car to communicate with a CCS fast charger. That communication is critical. If the handshake between the charger, adapter and vehicle does not happen correctly, charging may not start.
Charging stations can receive software updates. New charger models appear. Different charging networks may behave slightly differently. Some cars may also require small timing or communication differences during startup.
Good firmware improves how the adapter handles these real-world situations.
Firmware support should be one of the key things buyers look at before choosing a CCS to CHAdeMO adapter. The adapter you buy today needs to keep working in tomorrow’s charging network.
Why is the Longood adapter different?
To the best of our knowledge, the Longood CCS to CHAdeMO adapter is the only CCS to CHAdeMO adapter with an independent open-source firmware project developed around it.
Most other adapters are completely dependent on the manufacturer for future firmware updates. If the factory stops developing updates, compatibility may slowly become a problem as charging networks change.
With the Longood adapter, there is an active community behind the firmware. This gives the adapter a stronger long-term foundation. Even if the original manufacturer were to slow down or stop support in the future, the community can continue development.
For buyers, that is a major peace-of-mind advantage.
Is the open-source firmware stable?
Yes. The open-source firmware for the Longood adapter has reached a very strong level of stability and practical usability.
It has been developed around real-world use, real charging sessions and real compatibility challenges. CCS to CHAdeMO adapter performance cannot be judged only in theory. It has to work with actual chargers, actual cars and actual drivers.
The software has been improved based on user experience with different CCS chargers and CHAdeMO vehicles. Compatibility problems are often discovered in everyday use, not only in a controlled test environment.
Of course, no adapter can guarantee perfect performance with every charger in every situation. Charging stations can still be out of order, occupied, updated, misconfigured or temporarily incompatible.
The Longood adapter has a strong update path if compatibility issues appear.
Does the manufacturer use the same firmware?
Yes. The manufacturer has also adopted this open-source firmware solution and now supplies new adapters with the same software.
The open-source firmware is no longer just a community project for advanced users. For buyers, this means there is no separate “official” and “community” firmware path to choose between.
Why does this make the adapter more future-proof?
The charging network is changing quickly.
Across Europe, CCS has become the dominant fast-charging standard. New charging stations are usually built around CCS, while CHAdeMO availability is no longer growing in the same way.
For CHAdeMO drivers, this creates a clear problem: the car may still be good, but the charging network around it is changing.
A CCS to CHAdeMO adapter helps solve this by giving a CHAdeMO car access to CCS chargers. But to remain useful, the adapter also needs to keep up with changes in charger software and charging behaviour.
If a new charger model or software update creates a compatibility issue, the firmware can be improved. If users report repeatable issues, developers can investigate them. If a new feature would make the adapter easier to use, it can potentially be added.
This makes the Longood adapter more future-proof than an adapter that depends only on factory updates.
What useful features does the open-source firmware add?
Open-source firmware is not only about long-term support. It can also add useful day-to-day functions.
One practical example is the ability to check the adapter’s internal battery status.
The Longood adapter has an internal battery that powers its controller electronics. If the internal battery is too low, the adapter may not start correctly. Battery status is useful information for the driver, especially before a long trip.
With the open-source firmware, the adapter can indicate its battery level with LED flashes before powering off. This gives the user a simple way to understand whether the adapter battery level is low, okay or good.
In real use, it is practical. If you are planning a trip, you want to know whether your adapter is ready before you arrive at a fast charger.
Other advanced functions, such as improved logging, can also help with troubleshooting.
Should you install firmware files from random sources?
No.
Even though the firmware is open source, buyers should still use the recommended update file provided through the correct support channel.
A CCS to CHAdeMO adapter is high-voltage charging equipment. The firmware controls important communication behaviour during fast charging, so it should not be treated casually.
If you buy the adapter from Autonlaturit.com, the safest approach is simple: use the firmware version recommended by Autonlaturit.com and follow the update instructions carefully. The latest recommended firmware version is always available on the Downloads page at Autonlaturit.com.
How are firmware updates installed?
Firmware updates for the Longood CCS to CHAdeMO adapter are installed using a USB-based process.
The adapter package includes update accessories, and the update file is copied to a USB flash drive. The adapter then reads the firmware file during the update process.
The key point for buyers is that the adapter is designed to be updateable. You do not need to send the adapter away just because a firmware update becomes available.
A charger compatibility issue does not automatically mean the adapter is obsolete. In many cases, firmware support is exactly what keeps the product useful as the charging environment changes.
Why does this matter when comparing adapters?
When comparing CCS to CHAdeMO adapters, many buyers first look at price, voltage rating, current rating and connector type.
Those things matter. Firmware support may matter just as much.
Two adapters can look similar from the outside but be very different in real use. One may have little or no update path. Another may have active development, real-world testing, community feedback and a clear way to improve compatibility over time.
Open-source firmware should be part of the buying decision.
Before buying any CCS to CHAdeMO adapter, ask:
- Who provides the updates?
- Is there active development?
- Has the adapter been tested with real charging networks?
- What happens if a charger stops working after a station software update?
- Will the seller help with troubleshooting?
- Is the adapter supported by a wider community?
For the Longood adapter, the answer is unusually strong because both the manufacturer and the open-source community are now part of the same support direction.
Does open-source firmware make the adapter safer to buy?
It can make the adapter safer to buy from a long-term support perspective.
The biggest fear with a specialist product like this is not only whether it works on day one. It is whether it will still be supported later.
Open-source firmware helps reduce that risk.
If compatibility problems appear, there is a path for investigation and improvement. If new CCS chargers behave differently, firmware can be updated. If users discover useful improvements, they can be discussed and developed.
This gives buyers more confidence that the adapter will not become unsupported simply because the original factory changes priorities.
That does not replace the need for a good seller, clear instructions and proper customer support. In fact, those things are still very important. But open-source firmware adds another layer of confidence.
Bottom line
Open-source firmware is one of the most important advantages of the Longood CCS to CHAdeMO adapter.
It means the adapter is supported by more than just the original manufacturer. An active community can continue improving compatibility, fixing issues and adding useful functions based on real-world experience with different cars and CCS chargers.
The manufacturer has also adopted this firmware solution and supplies new adapters with it, which makes the Longood ecosystem stronger and easier for buyers to trust.
For most customers, the practical benefit is simple: you can buy the Longood adapter with more confidence because its software support is not locked behind one factory.
In a charging network that continues to change, that matters.
A CCS to CHAdeMO adapter is not only a piece of hardware. It is a long-term compatibility tool. And with open-source firmware behind it, the Longood adapter is one of the most future-proof choices available for CHAdeMO drivers who want access to the modern CCS charging network.
