Re: Foccci wakeup/sleep discussions

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 che...

Re: Foccci wakeup/sleep discussions

5.6v is not state B. B is 9V.

Re: Foccci wakeup/sleep discussions

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 ma...

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

Definitely. The plan could look like this: Add a CAN shield to a Raspberry or similar, to have a CAN which controls the huawei power unit. Then some lines of python are necessary in pyPLC to send the voltage and current demands on CAN, and to read the present voltage and present current from CAN. Lo...

Re: Foccci wakeup/sleep discussions

image.png 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 b...

Re: Foccci wakeup/sleep discussions

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.

Re: Can Bus question

To divide the search range I propose to look on the CAN, eg using SavvyCAN. In best case this shows that the messages are on bus (multiple times per second) and you could check their content.

Re: Can Bus question

It would be helpful if you describe your observed behavior and expected behavior. E.g. nothing is shown on your display, or values are arriving but with wrong values or missing completely or start ok and later are stuck or or or.

This leads to the next question. Which is the expected behavior? (E) It is normal, that the angle spot value changes multiple times from 0 to 360°. Because the angle is a "virtual angle" which counts per (resolver?) pole pair, not per physical revolution. (F) During one physical revolution...

Re: Type 2 to CHAdeMO Converter/Charger?

There are also 11kW public chargers, and drawing 22kW from them could blow the fuse. Means: evaluating the PWM makes sense.
And: There are public chargers with fix cable and plug. Means: Having a type 2 socket in the charger gives more flexibility.

Re: Dacia Spring 27 kw and Fronius Symo Gen 24

For the beginning, find out how many CAN busses go to the battery (hopefully 1). Find out the baud rate (with oscilloscope). Record some CAN traces (savvycan). Eg recording a complete short charging session and a short drive.

It does not help to try random things. The goal is to find the root cause, why the PP resistance is not 150 ohm. This is a simple resistance measurement, where not much can go wrong.

There are physical connection issues. Back to 8th of May: 2. When plugging and unplugging, you should see in the web interface resistanceproxpilot changing between 10000ohms (means infinite) to whatever your charger has. 3. If nothing helps, disconnect everything, use a resistor (something between 1...

Do you talk about this: [705380]? This is not a "log value numbering", this is the time since Foccci was powered-on, in milliseconds.
