Apologies in advance as I am new to the forum and only have rudimentary electronics knowledge. I have searched this excellent forum and google and have not found the answers I require so reluctantly have decided to post in seek of help.
I would like to build a Tesla style DIY replacement Nissan Leaf battery using 18650 cells that is liquid cooled. I understand that the Gen 1 Leaf uses 48 modules each of 4 cells at 3.75V and 32.5Ah each. The module is a 2S2P arrangement. So total system is 360V with 23.4kWh.
The motor is 80kW so I calculated the current required would be around 220A based on 360V.
So if I use the LG HG2 18650 cell 3.7V/3Ah/20A:
Module = 22 cells in parallel 3.7V/66Ah/440A
Pack = 12 modules in series 44.4V/66Ah/440A
System = 8 packs in series 355.2V/66Ah/440A
Total 23.4kWh 355.2V 440A
Are my calculations correct as I cannot find the motor current specifications and am uncertain about the requirements of continuous vs max current requirements and whether current requirement will be less as the motor is three phase.
Once again my apologies for what is probably elementary mathematics for most forum users.
