To me it would seem like a full Leaf battery pack is quite a lot of weight for a beetle. My plan was 30 of the 48 Leaf modules in the Squareback, that would be weight neutral. Adding 10 more is like having a full tank of gas and some junk in the boot. Much of the pack weight on the leaf is the cont...

My problem is laying my hands on the vehicle, all the other bits are in hand.

NICE!

It would appear to be something shy of 5kw (220vdc x 30A = 6600w, DC-DC rating is 100A @ 13.6v = 1360w) and both share the 30A HV fuse :O

5kw aligns well with 8hp for the "typical automotive AC compressor" at full load, really efficient ones are around 6hp.

Especially for those applications where the Leaf stack is too tall, or all you get is the motor

So there is a test Damien has not done and published????

Just had another idea these days: If we want to do low power BOOST charging we should be able to use the auxiliary A/C compressor inverter to rectify 1-phase AC for us :) It feeds into the low voltage side of the buck/boost converter, so with the batteries connected to the DC bus on the high voltag...

It fits like a glove.

SWEET! I am certain this is superior to my (alternate) plan of just filling that space with J-B Weld

Should I ever decide on the GSx50H route, I think I will just buy the whole vehicle, tear out what I need and hand the rest over to a scrapper.

Yes, and it has been done, but.... Wolf goes over many of the pitfalls in his 52 video series where he changes pack module count.

Diesel, gasoline and ATF are all very similar in terms of pumping, I have used "fuel" pumps to pump all three fluid types with great success.

If we are not "shifting" between high and low, not much pressure should be needed for forced lube, although certainly designed to have it.

What is the reason that the external electric pump is needed when the internal mechanical pump works driven by MG2? The mechanical oil pump is driven by the input shaft, so if that is locked (as required to get motive tq from MG1), there would be no fluid available to the transmission for lubricati...

Ok so now I'm really confused Again apologies for my lack of electrical knowledge. I guess my question is, if I hook up the 24kwh leaf battery pack to the gs450h motor (with Damiens VCU board in between). What is the limiting factor for the power output? Not exactly sure what is being asked. Full p...

I'm converting a GS450h to EV, and aiming to make hit 150kw power, with roughly 60 miles range. I'm possibly buying a 24kwh Gen2 Leaf battery. That should be doable with the 24kWh pack :D From what I can see, it is rated to 228A current, so ~90kw @ 400v. - So from this info the answer to my questio...

Engine block heater screwed into PCV pipe works too

Thank you Sir!

Just wanted to say a huge thanks to Damien and Johannes for getting me into this passionate subject. Off to prepare for tomorrow's meeting where 'Ze Golf' will be on expo - IN RUNNING MODE!! 😁 🥂. Will post afterwards, but some pics for an idea of where I'm at. THANK YOU OPENINVERTER COMMUNITY! Very...

Could you determine if they are filled with an inert gas?

Watts in ~= Watts Out???

Yes in buck mode chargecur (well, rather unintuitively) refers to the INPUT current as that's where the current sensors are located. That is actually good for my application to avoid overloading the weak US circuits! I never considered installing an element on the battery side to test charging, I w...

RetroZero wrote: ↑Mon Aug 30, 2021 9:24 am I think that Mg1 resolver would not line up exactly with Mg2 and they would rotate in different directions. One has to be half the resolver parameter of the other.

I was referring to paralleling the Inverter outputs to increase power, but yea you need discrete control for the transaxle

1- to run MG and MG2, I'll need a 2nd adapter board - no big brainer there. What happens to the second boards precharge and main contactor signals? Do I prepare for wiring them in parallel to adapter board 1? I do not know why one could not use a single board to run both in parallel. I know you can...

For those interested in MachE stuff, Sandy thinks it is pretty good, some of the parts are already showing up on "Car-Part".

I checked the Parameter database and one user has the idc set at +/- 5000A and ocurlin = 300A as well as throtcur = 1.0A/% (as do I) with success.
