Because i will use ccs plug to communicate between EVs with focci

I have to set a communication between two EVs

If i use send func in one board
Also i use receive func in another board

Why i need slac operation or another things

Can i use just send and receive functions

I want to set a communication between two focci board

Is it possible without slac operation or anything

Just i want to communicate

I want to communicate two focci board from car to car.

Which function do i need to use in clara code

For example i send 10 variable also i receive 10variable from another car

I mean is is need pcb tests like emc, electric vehicle standards?

Is this focci board can use in realworld electric vehicle. Is is need any test or standard?

I tried with 1k and power supply. As you said im measuring 8.76 volt on cp side. So we can say charger is not working properly.
Also i will look led for state c and obc state


I went to charging station. When i connected focci board to ac station. Ac station cp voltage is ~8.65v. Focci is waking ...

This is the error. In state B the Foccci should have only 2k7 resistor, which leads to 9V nominally.

[Edit] On Foccci there is a LED for state C. You could try to switch this via the parameter ActuatorTest. This should lead to
- LED off, is state B, is 9V
- LED on, is state C, is 6V

[Edit 2] And ...

Sory. Focci in state b, charger cp voltage is 5.6v

Two ideas:
- check the voltage levels of the PWM with the oscilloscope. It should be -12V and +9V after plugged-in, and later, when the charging is active, it shall be -12V and +6V.
- Foccci does not contain more than the blue box. But if Foccci would have closed the state C switch, some chargers ...

If your charging station tells you a CP error, it want's to say that it did not detect the circuit in blue box.
I see three potential root causes:
1. The charging station is defect and tells bullshit.
2. The wiring between the charging station and Foccci is wrong.
3. The Foccci does not ...

What do you mean with CP error? Where/how do you observe this? Do you use CAN to control the state C? Does the charger close the relay if you just connect 2k7 and diode, and in a second step the 1k3? Foccci should do nothing else.


When i connected to ac charger im getting cp error from ac ...

Hi

I have 4.2 and 4.5 versions. Im connecting to Ac charge station. Im getting cp error. Actually it works with one charge station. But it didnt work with other two station.

What can be problem? Thanks nest wishes

Moved to renewables.

You gotta be more verbose here. What power level for example? Which comms interface?


ok.

Actually there is 48V input to 230Vac inverter for li-on battery. Im looking 250-400V input range.

Also generally inverters for solar panels. They are converting DC to AC. Im ...

Do you have an inverter recommendation that converts the 250-400V voltage range to 220/230V 50Hz voltage range?
It will be used with Li-on battery pack

I have tried with IND message. when the cp signal was %5 pwm duty, If we didnt receive IND message through 5sn, I decided AC charge

How can we detect AC or DC charging session as pev side?

Could the state B resistor also be on a transistor or a 12v square wave output to replicate the CP duty for AC charging?
I've given it a go, I can do a PR if you want? I've added another transistor, but perhaps a solder jumper would be ...

How can we detect that an ac or dc charger is plugged?

I have codico red carrier board. I have used stm32f4 to communicate with qca chip. I have used https://github.com/uhi22/ccs32clara. Can I make a ccs charge controller with this code. I know that I have to implement cp duty cycle and pp reading. How can I test stm32f4 and red carrier board as a pev ...
