Good morning everybody from Greece,

I am new at your forum, dont know too much and i will apreciate your help if you can offer to me .
One of my customers, need a movable DC Charger to power up empty electric car batteries that cant be moved .
So he needs to charged them just a littkle bit and ...

Does anyone know the difference between QCA7000/QCA7005/QCA7006?

I recently bought a Chademo to Tesla adapter on eBay for testing. After starting the Nikkei, the adapter sent a 5% duty cycle. Subsequently, the EVCC sent a SLAC request, but the adapter did not respond. Is ...

When encountering a Chevrolet vehicle, the first byte of the MAC address used by the EVCC is 0x33.
This has caused some charging stations to be unable to charge.

I highly recommend checking out the very earliest commits on open plc utils, specifically https://github.com/qca/open-plc-utils/tree/5326657419b48a2cb9e3f826014537ca2f592076

plcsnif.c and "nda" directory are still missing, but they are VERY well documented! You can reproduce all the files at this ...

I'm curious which power supply module they use.

I see two ways:
1. The cheap: capture the SPI traffic in the vehicle or charger, between the modem (QCA7000) and the host, using a Saleae logic analyzer (clone). I have a python script on my github to convert the saleae data into pcap, to view it with wireshark.
2. The expensive, universal, state ...

Thanks to this post, I found that MG5 and BYD atton3 also have charging problems.

The issue is with the Resistor hanging off the PP pin to 5v. Communications on the CP line work correctly. Look for my post in the charging section for more details.

thank you

I had the chance to examine the CCS DC fast charging controller module from a BYD Atto 3 today, and thought I'd share some findings. This module is similar to the Hyundai one , as in it talks CAN messages on one side and negotiates the CCS2 PLC data link on the other side.

This module only has ...

7kw DC uses a single-phase power module

Thanks for replying I am from China

Hello everyone!

I'm currently focused on developing DC fast chargers and I'm conducting a round of compatibility testing.
I'd like to invite EV owners to help me test with real vehicles.

At the moment, I have DC chargers available with the following power ratings:

7kW (small DC charger)

20kW ...

Hi everyone,
I'm currently facing an issue during DC fast charging interoperability testing and would like to seek advice:

When connecting BYD new energy vehicles to some CCS chargers, we observed compatibility problems between the EVCC and the chargers. The CCS charger manufacturers would like to ...

Thanks. It appears the GB/T DC interface uses two CC lines, one for the car and one for the charger.


1. In GB/T 27930 (DC), the CC signal is used:
6V indicates the plug is disconnected.
4V indicates the plug is connected.

2. In GB/T 18487 (AC), the PP or CP signal is used:
PP is for detecting ...

Can you give me your email? I'll send you your email. I'm not very good at using forums. Sorry.

Good morning, first of all, congratulations on this incredibly rich and fascinating forum and all the projects presented here. I am part of an Italian startup specializing in wireless charging systems, and I need to interface our system with an electric vehicle that uses the CSS protocol. I was ...

I have this manual, can I send it to your email?

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 ...

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 ...
