So, ~170kW, or 234hp, or maybe 200hp at the wheels. With the current 170V pack I am only seeing ~130-140kW due to IR drop. The new pack will be much higher voltage at ~310V, so much less IR drop, and less pack heating, but also full power all the time  . The new pack should be 150-200lbs lighter too, bringing the car down to ~2800lbs.
I am going with Enerdel CE175-360 cells, in a 6P arrangement up to 76S. It depends how much I can fit in... |
Those Enerdel cells have some impressive specs.
I remember seeing something like 15C discharge capability for 10S (fine for automotive use) Their new spec sheet shows well over 20C!!
I'm not sure what your controller can handle, but unless you're using a voltage booster, the 76S arrangement won't provide enough voltage for the MGR. Given the cell's pulse power cabability, could you re-arrange things a bit for 3P and 156S? That could provide about 1000A, and 561V nominal.
How do you plan to connect the tabs and make a pack out of them?
Do you have a ***cough*** cheaper than retail source?
