I'm in the early stages of building an EV and about to buy the battery.
I have a 150kw capable motor/inverter, and main priority is acceleration performance over range.
I'm looking at using Leaf Gen4 modules.
I could buy 24 Gen 4 modules to make a standard 40kwH Leaf pack
That's two sets of 96 series Cells in parallel at 350v
My budget could stretch to 28 Gen 4 modules to make a 46kwH pack
two sets of 112 cells in series at 408v.
As mentioned, I'm not so bothered about range (expect to recharge every night) so the extra 6kWh is not important, but my thoughts were that by having a higher pack voltage I can extract more power at a safe current for the battery.
My question to those with more experience than me is:
Is it worth spending extra money and carrying the extra weight of 4 additional modules for the benefit it will give me? Considering that acceleration, longevity and cost are important to my project.
Thanks
Dan
