Nissan Leaf inverter gen 2

[luuk191]

Hello,

I have been looking around for an answer for my question but have not been able to find a clear answer so hope someone can help me.
I'm looking into getting a Motor and Inverter that will work with the Brain Board. So I want a Gen 2 inverter. Is the Gen 2 inverter the inverter that comes in the newest Nissan Leaf version or is it the inverter that is also on the older EM57 motors?

Thank you in advance.

EM61 is the old motor, EM57 the new one.
Gen2 is the inverter that directly connects to the motor via 3 bus bars. https://insideevs.com/news/322914/nissa ... bly-video/

Oops. I mixed that up in my wiki pages. Will fix tomorrow.

Okay thank you for the response.

Is there any great difference between the Gen 1 and Gen 2 inverter power stages (other than physical appearance)?

I’m looking for maximum performance and wondered if it might be better to use the later Gen 2 rather than the Gen 1 which I have available.

They're both rated 80kW.
Zapatero here on the forum squeezes 140kW from his Gen2. You can only do that with the openinverter board and that only fits the Gen2.
There seems to be a "Gen 3" from the Nissan Leaf 2 (after 2017) that is rated 110kW. It looks much like the Gen2 inverter so not sure what was changed and whether the drop-in board would still fit.

Thanks Johu, I'll try to source to a Gen 2 inverter.
I think I read on here somewhere that a Gen 2 inverter will run a Gen 1 motor (as the resolvers are the same).
I'd like to use the Gen 1 motor if I can as it would fit a little easier.
I presume there's no downside to doing that?
