Alternatives to QCA700x for CCS

Post by mikeselectricstuff »

A comment on my recent YT vid on the Tesla CCS adapter



" HP GP modem chips are also available from ST, Lumissil and Vertexcom. The Lumissil part, IS32CG5317, is even stocked by Mouser."
Also on Digikey, but no datasheet - just a 2-page flyer

So cool! I am actually starting to develop a controller based on the IS32CG5317, so far it has been a much more pleasant development than working with the Qualcomm alternative ( and its limitations on documentation ). We are making a EVCC for a tender yacht / boat to charge in the harbour of "modern" yacht clubs ( they are placing fast charger in front of their buildings), in monaco for example.

What are your plans for this controller? I was considering doing the same but have been put off by the requirement for an NDA on the IS32CG5317 datasheet, which may make an open source implementation problematic.

I have designed a EVCC controller for a tender yacht for a client, which is highly integrated in their project / product. I am currently as a side project designing a more universal solution to offer publicly ( in another topic on this forum, but progress is slow since we are currently in the prime season of my other business of making custom solar panels for solar racing cars ). In order to obtain the necessary information to integrate the IS32CG5317 in a design you will need to buy the HW + SW development kit from any of the lumissil resellers, after purchase you will go through a NDA process ( which is VERY doable comparable to the qualcomm alternative, which is a pain to contact). You will indeed not be able to share the sources of the info that you obtain, however your own implementation of the hardware can be shared ( which is also what I will be doing ), the firmware / drivers ( from lumissil ) in source format for what I understood can not be shared, however the SPI - ETHERNET driver on the linux side (which it the main/only important part) will become part of the mainline source of linux ( I have no idea when ).

What are the public available informations for the QCA7005? From my current understanding there is neigher a data sheet nor pinout nor protocol available. Only found the reverse-engineered protocol description for the QCA7000 here: https://chargebyte.com/assets/Downloads/an4_rev5.pdf, but it's not clear whether this will help for the 7005. Does anybody have more infos, which could help to create a pcb with the QCA7005?

The QCA7000 and QCA7005 are the same chips. The QCA7005 just have some additional soldering benefits ("wettable flanks" https://www.besi.com/fileadmin/data/Fot ... aper_A.pdf ) and can be operated at -40°C.

You can get a complete PCB with the chip installed for about 30€. When the chip itself cost nearly 20€ then it does not make that much sense to make the afford and create an own PCB.

For 25€ you can get the "PLC stamp micro 2" from here https://chargebyte.com/products/powerli ... mp-micro-2

For 30€ you can get the probably better for development "PLC Stamp mini 2" https://chargebyte.com/products/powerli ... amp-mini-2

Devolo also have a board with the chip here: https://business.devolo.de/dlan-green-phy-module
Devolo SDK here: https://github.com/devolo/dlan-greenphy-sdk

Here a pricy, used board from a charging station with the chip: https://www.ebay.de/itm/125747107645

But if you need an own PCB, here is a (untested?) PCB-layout for the chip: https://github.com/Millisman/QCA7000
