Thank you for the offer. I am in the process of getting a gen3 160 kW stack with zombieverter instead. Matches well with my other equipment (i3 lim, vw heater, chevy heater, ISA, etc...)

I have now added fwcurmax derating at 110% * fmax
This would need testing with low voltage and a low value for fmax. Anyone volunteer? I don't have the setup right now


I am trying to get hold of a new motor + inverter right now. I have my old 30V test rig complete with relays and a pedal ready ...

As noted in the firmware rev 5.20r+ be very careful when revving the motor without load or other safeties in place.

I just grenaded my leaf motor/inverter and possibly also the coupling when revving in neutral gear to double check an imbalance I thought i sensed when test driving. I was used to be ...

Pinswap solved it, see attached test burnout picture...
Thank you Johannes!

Ok. I have the throttle wired directly into the inverter, totally cut off from the vechicle ECU. The Vehicle ECU still remains intact though. I will feed it with basic parameters later to get power steering etc fully functioning, as others have done. I have an Arduino DUE with CANDUE addon, managing ...

The throttle is the usual 5v deal (original rx-8), not CAN. Throttle works exactly as before according to logs.

Build page has been down prioritised in favor of building I have two years worth of build pictures and data ready though, I hope I will get around posting it soon...

Yes

I raised the rear of the car and spun the wheels by hand in first gear. See image "manual turn". Feedback is rather choppy as expected but angle changes when the wheel is turned.

I tried giving some throttle in neutral. Just the slightest nudge in angle with every throttle input, then the ...

Hello all, it has been quite a long time since my last post. I finished the hardware part of my build a few months ago (leaf motor with Johannes gen2/rev3 board and i3 battery in mazda rx-8)

I got the car running and driving with the "factory supplied" 4.77r firmware and basic parameters. I decided ...

Getting good contact to aluminium is a tricky business.

Agreed, this is my main concern.


Then covered with glue coated heat shrink tube to reduce ingress of moisture.

Water ingress is one of my major concerns for the whole project.
I've seen some sort of aluminium specific rust ...

More or less all of the swedish roads south of road E14 gets carpet bombed by salt every winter. We trade road safety against corroded and extremely dirty cars. To get the car clean in winter you have to spray the whole car with industrial strength degreaser, it really is nasty.

Used volvo XC90 for ...

Hello all

Safety when working on electric cars, conversions or HV batteries, is essential

I found these two videos that provide a basic understanding about the risks you face when performing a conversion, and what you can counter those risks with. A must watch for those getting started, and a good ...

Nicely done!

Your battery boxes look very similar to mine (Still haven't documented my work here.. :( ). I use BMW i3 battery modules which have more or less the same form factor as the soul modules. The engine bay of the FRS/GT86 looks luxuriously spacious compared to my RX8 build. I could only ...

Thank you muehlpower, you cracked it before my LIN hardware even arrived in the post!

Thanks for the info!

I have just bought the VW GTE water heater, made by DBK ( http://datasheets.dbk-worldwide.com/EN/Datasheets/WireHeaters/DBKITM_HV%20Water%20heater_eng.pdf )
They are plentiful, compact and cheap. Connectors for the unit is in the spec sheet. I hope I can get it running ...

Chevy Volt gen2 MSE718 DC-DC for $100

Only ships within USA, sadly

Mouser suddenly had the connector in stock, way ahead of schedule. Problem solved!

Hi all

The 12-pin connector 19418-0026 for the tesla gen2 charger seems to be out of stock almost everywhere for the moment.

Do anyone of you have a leftover/spare connector that I could buy? Preferably in Europe to make shipping easier and cheaper.

Regards

David

Thanks for all the input!

My main goal is to keep the batteries at an optimal temperature while driving. I currently do not have plans for fast charging, but of course the cooling system will come in handy if/when I decide to implement fast charging. Battery heating while stationary will be done ...

Hello all

I am currently planning and designing my cooling/heating system for the engine, inverter and batteries. I am using the EM57 motor with inverter.

I would like some feedback regarding what coolant temperatures you other Leaf motor/inverter users get during different driving scenarios. Any ...

Hey looks like a good DC-DC option just wondering if there was a part number to google/search for?


Ah, sorry. I forgot to add in the vital piece. the TDK 9M68 14B227 AB . Here is the label

I just bought the ford escape hybrid version, 8 M68 14B227 AB, supposedly rated ...

Nice find! Thanks for sharing. Just bought a 24284603 for my conversion. Although I think the other part no's you mentioned are for charging the HV pack? If I look up those part no's I get units with what looks like a 2-pin connector for HVDC and one 4-pin connector for (presumably) AC and proximity ...

Hi Bratitude

I am also running a Leaf motor and have gone the usual route trying out different clutch plates (Daihatsu, Volvo etc..) to no avail. I am interested in trying out your solution when it becomes available

I just got it all working, default motor settings were WAY off. I thought the Leaf board came with nissan motor settings pre-flashed. Assumption is the mother of all fuck-ups. Changed to Leaf settings from wiki and its revs silky smooth without errors

Thanks for the heads up, will install update!

Hello Oskar!

Are you based in the Stockholm area? In that case I could probably swing by and have a look. Maybe we could collaborate? I have my Leaf motor turning since yesterday (but with errors, probably from parameter settings/using only 60v test pack voltage)
