Re: Prelude conversion project - some questions

What this does mean, is that I need to mount the other two modules in some way. Actually, I believe that the CAN version will have a very different minimum start voltage. It might well be fine with the battery voltage as it is. If it's the nominal 312 V @ 20 A model, it is rated for 110-440 VDC, an...

Re: Prelude conversion project - some questions

Does that mean that pin E is the same potential as pack negative? It certainly does on the older Elcon/TC chargers that I'm more familiar with. I can't say for certain with the new chargers, but I'd say there is a chance of that. Some things never seem to change (like poor documentation of LED flas...

Yes, the AVC2 is indeed still connected with all of this. I had assumed that the AVC2 had a diode and relevant resistors in there to start with... otherwise, what's the point of it? It certainly has the diode; it's visible in the middle right of the AVC1, right next to the pilot pin. Connecting a 2...

Re: Prelude conversion project - some questions

I tried to change the resistor arrangement as per the Modular EV Power website's suggestions. I suspect a misunderstanding, or error in the web page. Putting a 880 R resistor between pilot Earth and ground caused a 'ventilation error'. Putting a 1.3kR resistor between pilot Earth and ground caused ...

Re: Ultra fast chargers (350kW/HPC) in Victoria

any idea what it is? I agreed with your TeslaMotorClub post: it is probably a 5B Maverick solar panel module . Though it looks rather too thin, and it's hard to tell the ratio of depth to height in the photo. Perhaps it's a small set. Plus, 5B usually deliver their own gear. So I'm not so sure now....

Re: Prelude conversion project - some questions

Does that look like it has internal switches and timers? Granted, no. But this is an AVC 1 , the predecessor to the AVC2, and the difference could well be the timer. A timer could of course be done in software with an 8-pin microcontroller. Also, there must be more components on the back of the AVC...

Re: Making a conversion J1772 / IEC 62196 capable

I wonder if the AVC2 is a bit too simple for the average charge point? Surely the whole idea is to be completely compatible. Maybe it's timing of one of the resistor changes, so the AVC2 should work with most EVSEs that aren't too picky. Jeff Owen has posted about some EVSEs needing proper timing, ...

That won't be too much current, under 40 A, but it might be a bit weaker than 3S2P in shady conditions. I'd say it's your best option.
