Good overview of the system, it's not as complicated as I thought it might be. Also I hadn't realized exactly what the precharge circuit was for before. Going to be doing a conversion with a leaf motor as well so it's great to see some in depth information.
I really appreciate the indepth description. I am converting my 2006 Hyundai Sonata. Into an all electric car and this video as long as many others on your channel is helping guide me to better knowledge and confidence. Keep the vids coming brother. Much love from philly
Thanks! Yes, regen on breaking is part of the plan, but I know that I will need to do a lot of configuration and testing in the software to get the car driving as I want it to, so keeping my focus on the basic operation of the motor first.
I have a nissan leaf motor with the dc converter and the recharger still part of the unit. Is there any way to use those items with the motor since they will be. Needed at some point in time?
Great Stuff! But now I have to aske a few questions :) What is the purpose of the capacitors and are you able to show how they are wired in a future episode? Also why use the electronic relay board? Could you explain how to use the software to program the relay board. Thanks!
Hi, well done on getting the wheels spinning. Im at stage where trying to spin motor on projects, one is at outboard other is on Land Rover gear box (two project not a boat car sorry, not yet) Mine is Gen 1 though and rather a few differences with wiring and control I'm at stage where sending can messages direct to Gen 1 inverter, and hopping to see it spin.
Wow, two projects at once, good effort! I tried to get the motor running just using Can messages, but didn't have much success, so I got a replacement logic board instead (this will be the reason behind the big differences to your wiring. ) If you are trying to control the existing inverter, then you should check out the work Damian Maguire has been doing, if you haven't already. He created an open source VCU for the leaf gen 1 and has put a lot of the information up on you tube and GitHub.
@@PerformanceEV I'm not sure he sharing all the info, is a lot of stuff their to tease us. But seem to be holding back, the code that shared does not seem to be about running the Gen 1 as he showing in video. I'm progress well do far, have the com's working sending can messages to the inverter. (Just getting an error and not to work out what step missed) And I have worked out how to power up the junction box to use for charging back up the Aux battery (Actual I shared that just the other day: myimiev.com/forum/viewtopic.php?f=23&t=4533&p=40483#p40483) Next step it to work out the on board charger back in to the battery.

Hi, My name is Dave and Live in Las Vegas, USA. I have 1973 Porsche 914 that was converted to electric 10-12 years ago. My question is about the Leaf Heat pump or at least AC. What voltage does the AC compressor run on? I assume the compressor takes a DC voltage lesser than the Leaf batteries can supply. My batteries are much lower voltage than the Leaf and are at 170 - 145 VDC. What can you tell me about the system? Thank you in advance.
Hi Dave, I haven't seen much on the Leaf Heat Pump and AC module, I know the car I got the motor had one, but it wasn't one of the parts I got with the drive unit stack. The output to it is from the Power Control Module, so I guess it is expecting 360-400v. Could you use a boost DC to DC converter to go from your 170 to closer to what the pump needs? Electric 914 sounds like a great project, they are an awesome looking car. Good luck
I am actually surprised that openinverter (Johannes' ?) board supplies 5V for positive/precharge contactors instead of 12V. Will need to dive into it more before my conversion.
The positive/precharge output itself isn't a 5v signal, rather an open collector output. The relay board that I used to interpret that signal and feed 12v to the contactors needs 5v power. I could run it from an external 5v source and have only the single open collector signal wire coming from the inverter itself. I am using the 5v from the inverter to minimise the number of different objects I have in that part of the car.
It's a great learning opportunity. I ended up buying things bit by bit as the funds allowed. I'm glad I picked up the motor and inverter first to start getting my head around it all.
Hi, I found this link good for trying to workout which size of resistor would suit. There are a few calculations based on the voltage and the capacitance of the capacitor.

Brilliant as an overview of what is happening under the hood. Many thanks.
Fantastic to see the overview of the major schematics talked through like this. Thanks

Thanks Antoine, glad the videos are of help. Good luck with your build.
I've just binge-watched the whole playlist. Awesome project and well documented, some great info being shared. Look forward to seeing more vids
Thanks. Glad you enjoyed it.
Well explained, it’s basically simple enough to follow. You may need to take advantage of breaking & deceleration to recharge the battery.

Also im using Gen1 and your Gen2 so some difference I have seen in Can messages just with those
Great vid. If you could put a vid just on inverters and how they work , it would be great. But stil was helpful thanks

@@PerformanceEV Thank you for your response. Great video BTW
Excellent video it was great for me , just a question : where would you add fuses and emergency stop ( or a kill switch) for safety ?
Thanks

Waiting to save enough to do the same :)

wich engine leaf do you have ! 110 hp or 150 hp because soon will be the 200 hp
How calculate resistance of precharge resistor for 400v battery?
Hi, I found this link good for trying to workout which size of resistor would suit. There are a few calculations based on the voltage and the capacitance of the capacitor.
