Re: Tesla charger programming/source code
Here is the code that need to be changed: // Find this: (line 390 or something, depending on version) evseread(); autoShutdown(); watchdogReset(); manualMode(); // Add the following: if (digitalRead(DIG_IN_2) == HIGH) parameters.phaseconfig = Threephase; else parameters.phaseconfig = Singlephase; Yo...

Re: VW T3 EV Conversion Kit
max. 80kW (continuous) The limit to comply with the max. 20% power increase rule would be 77kW The actual power rating of a motor, is not relevant. I use a Siemens motor, and can set about double the power output. If you have a openinverter board you can set whatever power level you want. So if you...

Re: Enova(!) Parameters
Seems really strange that it’s such a neat graph and can be produced consistently. I’m going to start looking into a different encoder but if those plots mean anything to anyone then let me know. Did test this today (Siemens ACIM motor) I got zero RPM at standstill, in RUN mode and off mode. I stil...

Re: Tesla charger programming/source code
I think I found a simpler way to do this. Do you think it will work? :? At least, this way it will not go boom, if contactor fails or get welded!! The charger will be in 1Phase mode all time, N-L1 connected to all modules. When there is 400VAC on L2-L3, contactor will close and connect phase123 to m...

How does your angle plot look like, at stand still and manual turn of wheel?

Re: Weird Speedometer Question
Maybe this is a stupid question, but can't you use the frequency output from the openinverter?
I use the "pwmfunc speed" for speedometer and servo steering. Works for me.

Re: Tesla charger programming/source code
That sounds like it would work yes. all you have to change/over ride is the variable for the phase wiring type.

The OEM setup on the Tesla can do this. Tesla have a module for this that connects to the Gen 2 charger AC. It's a stand alone unit that is not directly controlled by the charger. I posted some information on DIY Electric ( here ). It may not work with the open source controller. Thank you, will fi...

Re: Tesla charger programming/source code
The OEM setup on the Tesla can do this. The charger will always be in 3 phase mode, and only shift to 1 phase if missing AC on phase 2 and 3. If relay should close when on 3 phase, then AC fuse in car and grid will blow, and relay would probably go bad... No harm to charger or EVSE, as I can think o...

Programming question, can you help Tom, or anyone.... I want to be able to close a relay to short phase 1.2.3, when I charge at 1 phase outlet. Relay is connected to DIG_out_3. Is there a safe way to activate the relay in software? I was thinking to read ACpres or acvolt. If AC is only present on ph...

Re: What is (ab)normal plots, can you share your's?
My truck is drive able, but I'm not satisfied with slow speed jitter. And sometimes overcurrent.
Can live with it until Johannes will implement vector control for ACIM

Re: OpenInverter Mainboard in a Siemens Simotion?
As discussed in the beginning of this thread, the gate driver board has an active LOW PWM polarity. Does this mean I need a pull-up resistor to each driver channel (L1,2,3 High/Low), or is changing the pwmpol parameter enough? When I made the board for the Ford Siemens inverter (also with LOW polar...

Re: 10 kW PV System House Inverter Build
I can imagine a whole world of regulatory problems if you want to do a grid tie inverter.
UL 1741 and IEEE 1547 are the standards you need to follow, for a grid tie inverter.
I haven't thought about, switching between grid and your own power, but a grid tied one would work better, I think....
