I too would like to find out more information - before I tear this pack down into a 44v system for solar storage! apparently the EVS BMS can communicate but it isn't listed on the supported device list. If i did tear it down then I would have to cut the packs to make a 15S system - not wanting to d...

Hi,

Does anyone managed to create a documented thread including the code, HW design, HW connections, parts list, etc?

Thanks, Andrei!

Hi!
Nice work here!
Do you have any progress since your last post?

Thanks,
Andrei

Maybe someone is interested to see how much current can deliver this battery.
I have a video here in which I continuously discharge the battery with more than 540A for about 1.5 min.
The voltage sagging is about 9, 10% at this discharge rate.
Enjoy!

I found this BMW i3 CCS +Type 2 Socket and loom + the LIM module and all you can see in the add's picture for a resonable price, 2000 NOK which means almost 200 Euros. For me is to expensive, the shipping to Romania + tax costs me almost 400 euros in total. Maybe someone is interested to buy it. lin...

I saw all the videos months ago but now I was so exited to spin the motor that I've omitted some important steps in order to make the inverter work properly. I'm not technically savy enough to contribute to most projects here, but I try to do some smaller lifting on things being archived and docume...

When looking at your parameters posted in first post, "deadtime" is set to 0. This is what Damien had as well when he blew his up. To my understanding, setting "deadtime" to 0 only "works" in the prius gen2 inverters. I'm using a "deadtime" of the 63 in my pr...

I think most EV components are not rated for continuous load. For example the main DC rail in a solar inverter is like 100x20 mm and it will happily conduct 1000A all day. The DC rail of a Tesla inverter is like 20x3 mm and it will only conduct 1000A for limited time. You are right about this and f...

After testing the setup for a while without a cooling circuit, I decided to connect the Nissan Leaf OEM radiator and two of the recirculation pumps in order to cool off a bit the inverter and the motor. Then I decided to test them for about an hour to see how the temperature gradient will gonna chan...

I have finally managed to set up the inverter and the Leaf gen 1 motor connections for the resolver. :) I've connected the inverter to a 18S Nissan Leaf battery pack with a Chinese BMS which can provide 300A. You can see in the video bellow how smooth the motor is running. https://youtu.be/P_Kr6N4bx...

HIRESOFFSET - resolver mid value is too far away from 1.65V. Please check voltage on the S1S4 pin, should be around 1.6V LORESAMP - amplitude returned by resolver is too low, less than 0.8V peak-to-peak . Pull-ups removed? Checked excitation? On a multimeter on AC volts mode it should be about 3V R...

I am not sure if this tpic already exists but I need some support for my project. So far I managed to spin the motor with the 5.00.R-Sine SW in manual mode. When I tryed to configure the 5.00.R-FOC, I observd that the parameter "angle" shows a value of 8.21 degrees and when I tryed to plot...

What amperage?

I think that the gen1 and 2 are almost the same. The hole pack can easily support 1000A RMS current.
You can find a detailed benchmark here: https://www.energy.gov/sites/prod/files ... 2013_o.pdf

Hi, I've just teared apart my damaged gen.1 Nissan Leaf inverter. Here are some photos with the IGBTs.

I have a battery from a 2 gen Focus EV and I want to use it for a conversion. I also have 6 modules from a second Focus EV gen 2. I am willing to use all of them in a 108S configuration and mabye I can use the two original BMS from the Ford batteries. If you find anithing about the BMS, pleas make a...
