Is acceleration charge state dependant?

[MacherAWD]

I know with my old Bolt, the car was faster with a 90% charge, then with a lower charge (or something to that effect), does the same hold true for a Mach-E, is it faster with a full battery, and if so, how much faster? I have an AWD Select.

Ford is super conservative. You lose maximum power for a variety reason. State of charge being one. hell, if I maintain a constant speed of 72, I don't have full power if I accelerate.

I rarely every have full power. There's almost always some condition holding back full power.

Yeah I can go faster in Georgia than I can in Florida

The total pack voltage goes down as the state of charge goes down. So for all (there may be some weird edge case) EV's, acceleration is a little better a full state of charge than at a lower state of charge.

For perspective a full SOC pack is at ~400V. at 50% SOC it is at ~370V That difference in voltage means there is slightly less power available to the motor(s) at 50%. and so on.

Yup, I notice a pretty huge acceleration drop when at the battery is at 35% and less. It probably happens at 50% but I have not noticed it. I do not hot rod much.....
