Re: charging station / wallbox hardware basics

An alternative design for a AC wallbox without any microcontroller is shown here: http://www.analogevse.xyz/AnalogEVSE-de.html (Thanks @Age for the hint)
This could be trimmed to generate 5% PWM, so it would also support digital communication, by adding a homeplug PLC modem.

Re: Implementing communication to a car with a greepPhy enabled AC charger via ISO 15118

Hi and welcome, your chapter selection makes sense. The intended sequence is described here: https://github.com/uhi22/pyPLC?tab=readme-ov-file#example-flow (for DC, but for AC the beginning is the same). Seems you are stuck at checkpoint 200, the SDP request. The car should send this (an UDP broadca...

Re: QCA7000 Foccci+Clara User thread

Foccci/Clara are quite relaxed regarding the preconditions for starting the high level communication. Neigher the PP nor the 5% PWM nor the StateB (9V) on CP is necessary. Only power, and starting with version 4.5 something to wakeup (e.g. wakeup line). This should be sufficient to be get a demo cha...

Re: charging station / wallbox hardware basics

Building blocks - controller: evaluates the voltage on the CP and generates the 1kHz PWM - amplifier: gets the PWM from the controller, which is a 0V/5V signal, and creates a +12V/-12V PWM out of this. - power supply: provides 5V for the controller and modem, and +12V and -12V for the amplifier. - p...

charging station / wallbox hardware basics

This thread is intended to discuss the hardware basics of a "charging station", both for AC and DC charging. Start of the discussion was the EvseMode of pyPLC (here: https://openinverter.org/forum/viewtopic.php?p=71881#p71881 ). For AC charging, a do-it-yourself approach is available here:...

Re: First-Time Config of FOCCI And CCS1 vehicle charging

Question: does the test mode only test if the lock opens or closes, or should it also test that the motor operates for LockRunTime? The implemented behavior is not really consistent. The answer is yes and no. As long as the ActuatorTest is OpenLock or CloseLock, the lock motor is controlled. The ti...

Re: Foccci wakeup/sleep discussions

Had a look, nothing obvious found so far. Setting the PB1 to high works, so no idea so far why the PB4 gets a pull-up. Edit: Found a hot candidate. The pull-up of the PB4 starts quite early, ~3.5ms before the PB1 gets high in initialize_pins(). This means, this pull-up seems to come quite early in t...

Re: First-Time Config of FOCCI And CCS1 vehicle charging

I have a couple of questions on the Clara parameters: 1) UdcDivider: Is this only used if InletVtgSrc is set to 1? If it is being used, it should be mapped as a 'Receive' message? 2) What is the purpose of InletVoltage? If I supply it via CAN, I must measure across the charge inlet DC pins and not ...

Yes, this should be fine. Even just running CP and L in the same cable for a meter should most likely be sufficient coupling.

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)

Nice small converter. It seems to have a diode-capacitor-ladder to bring the AC to a multiplied DC voltage. So it is able to deal with back-feeded DC with no harm.
