Explore all possibilities of ISO15118, including V2G/PnC/hardware sniffer.
Hello everyone! I am an embedded software engineer from China, specializing in the development of new energy charging piles. I have extensive experience in developing embedded software for QCA7000/QCA7005, supporting ISO15118 and DIN70121. I look forward to sharing and discussing challenges in the development process with all of you.

Hello!
I am working on a similar project. So far, what we could achieve is to join the AV network, but we cannot capture the TCP packets. Any ideas how to overcome this?

After successfully joining AV, you should transplant a TCP/IP protocol stack that supports IPV6 and then listen to SDP requests

Importance of Frequency Deviation in EVCC/SECC Product Development
During the development of EVCC (Electric Vehicle Communication Controller) and SECC (Supply Equipment Communication Controller) products, hardware and software engineers often refer to standards such as DIN EN ISO 15118-2 or DIN SPEC 70121. However, the GreenPHY standard is often overlooked, despite the fact that it forms the foundation for EVCC and SECC protocols.
The GreenPHY specification, specifically section 3.7.3.1, defines the acceptable maximum frequency deviation as ±25 ppm (parts per million). This crucial specification is frequently ignored or even unknown to many EVCC and SECC manufacturers. Therefore, I’m highlighting it here to increase awareness.
Frequency Deviation Tolerance of Popular Chips:
Lontium MSE102X series: Maximum frequency deviation tolerance of ±136 ppm
Qualcomm QCA7000/QCA7005: Maximum frequency deviation tolerance of ±50 ppm
Lontium recommended frequency deviation: ±10 ppm
A smaller frequency deviation improves hardware compatibility. If your product maintains a smaller frequency deviation, it may be able to communicate successfully with devices that fail to meet the frequency deviation requirements. In contrast, competing products with a larger deviation might not function properly.
In conclusion, it's crucial to minimize frequency deviation in your EVCC and SECC products to ensure better compatibility and reliability, particularly when working with devices that exceed the standard frequency deviation limits.

Hello, I'm an engineer from China and I'm currently researching ISO 15118 as well as related aspects of DC charging stations. I have many questions about PLC and networking. Would it be possible to provide your WeChat so that I can purchase some of your free time to consult with you?
