In one of those 'long roadtrip random thoughts' exercises, I started to think about the parameters on the battery in various SOCs and how that might impact maximum output of the motor and thus acceleration. It would seem likely that as SOC drops and thus voltage drops on the pack, there would be less energy available to the motor at any given moment. However, this might be masked by controller tricks that keep amperage in a relatively constant range regardless. My perception (and I have not (yet) done the simple thing of collecting data from various SOCs), is that when the battery is in a high SOC, particularly right as it comes off the charger, the car has more oomph. And that as it gets toward the lower end of SOC it's a bit more 'leisurely'. But perceptions can easily be fooled by preconception. Does anybody have data and or formulae on output vs SOC?
