If no solution, what about this workaround? Switch between two modes:
1. Power the inverter with a Leaf or other weak battery pack, while charging the small NMC battery. (normal mode)
2. On high demand, power the inverter from the NMC battery alone until it discharges a given amount, and go back to ...

Damien, Sir, Jack, Mr Bauer...
If I have to, I'll mail you a new hacksaw blade, but I can't afford private consultation for this.

You often say you don't like to repeat yourself and to go back and check previous videos. I have, extensively. I finally found maybe your only reference to this subject ...

When he planned his Honda re-rebuild in September 2003, the 160 capacitors would cost him $4800 on a liquidation sale. I don't know if he built it. Maxwell has changed their products in 19 years. But now the prices have dropped dramatically, brand new cost is $9 each in quantity, such as this ...

I found a solution using batteries and supercapacitors, but can only read the abstract:

https://ieeexplore.ieee.org/document/9432946

Any ieee members on here able to share with lay folks whether a battery and supercapacitors can be combined inexpensively enough?
Whether the ideas explained in ...

There's another possible way to wire this:

Could Toyota DC boost converters be used? The reason is for the complete isolation of the batteries through any available circuit. Toyota DC boost converters look like they can handle the load. Can they? That they raise the voltage might be considered a ...

Here is one clean solution:
Single custom pack with used but selected good Leaf modules, three modules paralleled at the cell, using the Leaf BMS. That's 144 modules in one pack, about 60kWh, up to 240kW max. Tune down to 200kW max to not cook batteries. That's 1152lbs/523kg in just modules.

Most ...

@DougEV Interesting idea and I wish it would work with discrete components, but all kinds of problems occur. Or so I'm led to believe.

By isolating the batteries and sharing only the outputs of inverters, converters, or other devices; each battery pack can have any properties: voltage, max rate of ...

Not sure where to ask this.
Nissan Leaf gen1 battery packs purchased as cores are my cheapest choice; which I conclude by asking all my cheapest local wrecking yards. They will sell me any that don't work as a core, $500 for early Nissan 24kWh and they have not yet seen newer ones, or any random ...

In brakes, with pads, you need most breaking power up front, maybe 70/30 or 60/40. I want the same for regen to slow the car evenly front to back in loose gravel or black ice in turns. I figure (with nothing to calculate from) 50-75kW up front would serve the purpose.
Inspiration?
Seeing Damien ...

He does. I watched most of his content. I mentioned him above. I'll use some of his tricks. He does things right, upgrading to a 40kw battery and a 160kw inverter; all Nissan Leaf, keeping Nissan happy. Nah, that's not my style.

I guess this thread should be limited to a Gen1 with an EM61 motor ...

original post updated to reflect responses

Thanks you two! I thought there was no support for the EM61 motor. Of course I'll use the original EM61, that's awesome! They are cheap enough to abuse and replace if it comes to that. Is there a thread on installing openinverter on a Leaf?

As for a battery, I made a long project of figuring out my ...

Yeah, the Leaf is a piece of crap. But I see these pieces of crap for sale for as much as $9K locally if they can go over 50 miles, and sometimes $1K because they 'quit working.' That's a large margin. I will not drive an 80kw car, and 110kw is only a bit better. 160kw is unobtanium, and cost more ...

Not to derail the request for the cheapest solution, but I'll bet a Tesla Model S front SDU with a Zombieverter would fix things right up! Those Tesla drive units cost $1500 shipped on ebay; which is less than a 160kw Nissan Leaf motor and inverter.

[revised as I learn]
Premise:
Calling all the nearby junkyards has me convinced that Gen1 Nissan Leaf battery packs purchased as cores are the cheapest EV modules available in the USA, and probably will be for several years. Leafs die from heat in California, but less than half of the modules are ...

Let's figure out a replacement for the noisy, troublesome external oil pump on the GS450h L110 transmission. I'd like to use one, but not with this problem. Don't make Damien figure this out, he's got enough to do. :)

Here are the facts (which will be updated and collected here, to not have to ...

What currently supported inverter(s) would be best to use in the same car, for a L110/L210 and a P310/P313 for AWD? This allows as much as 600hp AWD using Toyota/Lexus transmissions (whining louder relative to speed at four similar but not equal tones, plus a box of hammers oil pump), or maybe 400hp ...

Does anyone know how to manage more than two traction motors?
I figure it would need two inverters with two channels each, but does one controller handle both or would one be slaved to the other?
update:
Forget the Q211, put a P310 (Highlander, Kluger, RX) or P313 (RAV4) up front, as they are the ...

Hi All,
I’ve been observing for a while, and watched nearly all of Damien’s videos and quite a few of Johannes’ videos. I have the technical background to deal with this from the electrical and mechanical sides but am no expert. All I know about inverters is what I learned here. The following is my ...
