Welcome!
I have no input at all to your actual question.
Just wondering: how hard would it be to repair the 15V converter?

Re: [WIP] Caterham Seven - Putting the EV in sEVen
I don't think you need to worry about the intricacies of the CCS protocol. It is just a super stupidly convoluted way of controlling basically a very big lab power supply. You tell it how much current you want and at which voltage it should throttle. Two data items. And an extra one with the battery ...

Re: [WIP] Caterham Seven - Putting the EV in sEVen
Is the DC2DC set to a fixed translation ratio or fixed output voltage? If it's a ratio it should be pretty simple. Just divide the current the BMS allows by that ratio. CCS precharge voltage is the DC2DC converters output voltage.

Re: AC charging with Foccci and Zombie, not starting
I think I will change the "nothing plugged in" action to edge triggered so it fires only once when someone without lock just unplugs.
Right now it also inhbits the stateC test I guess

Re: AC charging with Foccci and Zombie, not starting
The last time I tested the ActuatorTest wasn't disturbed as long as no cable is plugged in. So testing "Lock" locks it and only testing "Unlock" unlocks it. As soon as you plug in a cable the application logic takes over. Can you check that?

Re: [WIP] Caterham Seven - Putting the EV in sEVen
Well thumbs up first for the project in general 
But same question - why do you choose an 800V motor with 200V batteries? Why not match them? The converter just adds losses, weight and a potential failure point

Re: AC charging with Foccci and Zombie, not starting
I'm going over the code changes, looking where I changed semantics.
1. I changed CanWatchdog to require ChargeCurrent AND enable to be continuously updated. Before updating one of them was sufficient https://github.com/uhi22/ccs32clara/commit/36a5473aa93c267802ef86d6f9abb8d7c5bb8638

In Audi A2 I run the contactors similar to Zombie. It's Nissans 39 Ohm precharge resistor and it takes only a few 100 ms. Click, click.

Re: AC charging with Foccci and Zombie, not starting
unfortualitley some code changes broke things that I had working by others
Can you pinpoint what exactly broke it?
I mainly did cleanup work and added standalone charge mode. But also did some bugfix where starting AC charging again needed a power cycle. And I may have changed AcObcState ...

If you get rid of the vans you're no longer the man with the van, huh? Lot less to drive.

Re: LDU direct to VCU ?
I guess the answer is it was never intended to be used at that amperage but if it works for you, you can do it at your own risk.
The LDU inverter probably consumes 1-1.5A when spinning a motor. Have you tested that? Does the low side driver on Zombie become warm?

very cool hack!
Would it be worthwhile to set the MPP controller over 14V? The Gen2 Prius DC/DC by default outputs 14V (but probably Toyota adjust it...)

Re: Leaf AC charger socket polarity
That's cool but from my study of the topology doesn't matter. Both cables run through a number of common mode chokes and finally a rectifier.

Yep, typo in my opening post, should say V7, V8. This thread doesn't apply to your board then. Just make sure the 3.3V rail is dead stable. Measure between some GND and the upper rightmost pin of the wifi module socket
