Could I see your code? I have a lot of experience programming Arduino. Perhaps I could optimize the code for greater speed and performance.

I think you should use the battery's internal resistance value. For example, if the battery voltage without load is 352V(4*88), the battery resistance is 66mOhm. If you give a load of 100A, then the voltage drop across the batteries will be 6.6V, the total voltage will be 352-6.6 = 345.4V...

Hi all. I finally assembled the first block of 44s. Missile attacks by russian terrorists did not allow me to do this quickly enough.

I have extensive experience repacking Nissan Leaf and KIA Soul batteries using these cells. I solve the issue with battery capacity using a CAN bridge and my own software. This allows these vehicles to use the full capacity of the new battery. At first glance, the i-miev algorithms are much...

The ribs of the bottom cover were cut off with an angle grinder. Clearance is approximately 15mm, it is difficult to measure more accurately, but the finger fits freely Cells are sold separately. I will assemble 2 blocks of 44s in holders of my own design SK cells are used by Hyunday/KIA, VW...

I have ideas on how to fix this. I won’t reveal all my cards for now, but if I succeed, I’ll definitely share it.

You're right. The price per cell is 16 euros/piece. and European manufacturer. I don't really trust the quality of the Chinese. In addition, I get a total reduction in battery weight of about 50 kg. Here is a charge/discharge curve based on manufacturer data Very similar to the curve from...

I created a separate thread to discuss this project. In it I answered your question. https://myimiev.com/threads/making-a-custom-battery-pack-for-miev.5459/

Hi all. I recently bought an i-miev with a faulty battery. I want to remake the battery myself with new elements. According to my calculations, the cost of the conversion will be about $3,000. The approximate battery capacity will be 25 kWh. Cells SK Innovations E777. I have already designed a...

Thanks Mickey! At the moment I am at the beginning of point 1. I have already designed a block with 44 cells. It is slightly smaller in size than the 5x8 LEV50 blocks. This is what it looks like in the picture.

Hi all. I recently purchased an i-miev with a faulty battery. I want to remake the battery with new cells myself. According to my calculations, the cost of re-equipment will be about $3,000. The estimated battery capacity will be 25 kWh. Cells SK Innovations E777. I plan to cover the...
