Fisker Ocean One charge at home requirements

We were hearing from the recent video that it can charge 0-80% in 30 minutes at a 250kwh fast charger. You’ll need someone better at the maths than me to convert that to the home rate assuming a 50A setup (40A usable) in the garage.

otherwise, looks like 30 minutes for 80% charge at a fully functioning fast charger.

Useful conversions: 

240V / 40A = 9.6 kw

240V / 32A = 7.7 kw

240V / 30A = 7.2 kw

If Ocean has a useable 110kwh battery then 5% - 80% = 82.5kw => takes just under 11 hours on a 32 A charger

If Ocean has 110kwh usable for 350 EPA miles then it is 315 wh per mile (we do not know this yet). 

A 32 A charger at 7.7 kw = 7,700 w / 315 wh per mile = 24 miles per hour of charging at home on at 32A charger

A 40A charger at 9.6 kw = 9,600 w / 315 wh per mile = 31 miles per hour of charging at home on a 40A charger. 

Using same 315 wh / mi assumption from above, at a 250 kw peak charging rate, Ocean can charge at a maximum speed of 4.16 kw per minute or 13 miles a minute (780 miles per hour). No idea how long it can hold the max charging speed or how quickly it tapers. If it can go from, say, 10% - 50% at an average of 200 kw, then it can add 140 miles in 13 minutes. But we are piling assumption on top of assumption at this point. 

A good guess is that in practical everyday driving where you stop to recharge with 30-40 miles left on the battery, Ocean can add around 200 miles of range in around 18-20 minutes and 250 miles of range in around 30 minutes.

Fisker has announced that they are confident of manufacturing and delivering Ocean One in November 2022. That is only few months away. 

*sigh*

@bayoubob thank you for compiling the estimate. This is helpful for new EV owners. Doesn't have to be accurate to the mile. This helps.
