Re: PEB Kangoo cloning

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.

Or another way to look at it: CCS charging is no different to regen ...

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?

EDIT: nevermind, genius here added some new logic to ...

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

I'm going over the code changes, looking where I changed semantics.

Re: Precharge time

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.

Which sort of makes sense: https://www.digikey.se/en/resources/conversion-calculators/conversion-calculator-low-pass-and-high-pass-filter

unfortualitley some code changes broke things that I had working by others

Can you pinpoint what exactly broke it?

Curious how that will continue :) If you get rid of the vans you're no longer the man with the van, huh? Lot less to drive.

Or otherwise I hope you can eventually switch to a low maintenance electric van because... it's kind of a thing on that forum ;)

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?

Re: 2008 Nissan Quest Van with Tesla SDU.

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...)

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.

You can either flash stm32_sine.bin OR stm32_foc.bin . NOT stm32_sine/foc.bin

As said, you need to flash stm32_sine.bin.
