Oscar even takes this further and predicts your state of charge at a destination including taking up…. […]

Also the Oscar route calculator will not include stops, such as batttery switch stations, if it estimates that you will arrive with 12% battery or less. This margin of error, IMO, is too large, and prevents OSCar for calculating the most efficient routes. I was told (by someone who I believe no longer works at BP) that the margin of error on the new OSCar will be smaller.

By all accounts you have 6 to 8 km once it tells you 0%.

I wonder if they do they build in the same margin of error in the Oscar software? Or is zero really zero?

Kilowatt (kW) is a unit of power, used to quantify immediate power, as in “right now the car is drawing 20 kilowatts from the battery”.
Kilowatt-hour (kWh) is a unit of energy, used to express capacity, “this battery has a capacity of 22 kilowatt-hours”, which means “this battery can deliver 22 kilowatts of power for 1 hour.”
The unit is literally defined as kilowatt x hour.
