Range Calculations

Restoring and Building | Posted by admin October 28th, 2010

a

WH=V*AH

Perkert (Adjusted capacity based on perkert principle) 60% capacity

Usable WH = 80% perkert adjusted capacity

AH Used – read from Zillaconfig

AH per Mile = AH used/miles driver

WH per mile =AH per mile x Pack Voltage

Range = Usabel WH / WH per mile

Looking at the above calculations, below is the spreadsheet modified for Lithium pack and comparison of range and cost.

With a Lithium 50 cell 160AH pack the car would have almost an 80 mile range.
