"fast charging system capable of a complete recharge in an hour when charged with the Tesla-proprietary SuperCharger"
Tesla have consistently said that the supercharger will not be able to do a complete recharge, the battery is most capable of accepting charge between 30 and 80% and it is this range in which the supercharger works. So a Tesla driven down to 30% can be fast charged 50% back up to 80% in 30 mins but this does not mean a 100% charge can be performed in one hour. A charge from below 30% or to above 80% will have to occur at a slower rate limited by the battery chemistry.
