So, I know JB has talked about ramping up the SC delivery power to drop the recharge time and the current SC installations in Europe are at 135KW, what would it take for Tesla to begin using 150KW in the US? And what would that drop the "half charge" recharge time down to? Or, would they try and jump to 200KW? Here are my guesses:
Changes required for either the 150KW or 200KW SuperCharger installs:
- One Tesla skid mount 400 KWh storage units per 4 charging bays
- Additional transformation to drop the charging current but up the charging power...not sure about this one...?
- Cooling fans for blowing air across the underside of the pack to help control temp
- New firmware for managing the recharge cycle
I would guess that 150KW charging would drop the "half charge" time down to 15 minutes but 200KW charging might drop it to 10 minutes. These new stations would have a larger footprint and be much more expensive but might be really popular in areas where there is a high density of Teslas.
Anyone have any other ideas or thoughts about how this might be achieved?
