45 Minute QuickCharge

[Lloyd]

No, not all. Tesla recently (December 22nd 2011) released the options and pricing for the Model S where they revealed that the 45 Quickcharge won't be available on the 40kWh battery pack.

This statement is not true. Tesla never said that quickcharging would not be available. Tesla stated that for the 40kw battery supercharging network would not be available.

How would you phrase this? I'm trying to keep a clear picture for new users to this forum. That when they read the topic start they have an idea of how it works.

There seems to be some issue about the difference between "Supercharging" and "Quickcharging." I know what Supercharging is: using Tesla's proprietary 90kW Superchargers. I'm not sure what is meant by "Quickcharging" though. As far as I know, the next-fastest charging option below Supercharging is to fully use the 20kW twin on-board chargers.

Which is not 45 minute charging, so Wido's statement is true.

The 40kWh version can take half a charge in 60 minutes using a second inboard charger and the HPC. This compares with the 85kWh version taking half a charge in 30 minutes using a DC supercharger. The second inboard charger and HPC can be afforded by all who buy a Tesla. The DC supercharger will cost as much as a whole car when installed.

Quick charging is the generic term used to describe fast charging - eaither DC or AC. It means charging to 80% in less than an hour.

Sometime back it was called L3 - which is no longer used. SAE uses "fast charge".

My suggestion for the thread is to use SuperCharging - since is no known support for any other type of QC.

I'm not sure I'm clear on this. Will the supercharger use the same charger port than we would normally use to charge the vehicle? That doesn't seem to make much sense, it seems like it would be better to bypass the built in charger(s) in the car itself and go straight to the battery. Do you think there will be a separate special supercharger connector located somewhere else on the car?

[Lloyd]

No, I was told it will use the same connector, but I don't know what mechanism they used to bypass the AC onboard chargers.

The supercharger will use the same plug as your home charger. Not sure how the hardware works but it does bypass the car's chargers as the DC charger is external to the car.

The way the CHAdeMO socket works is there's a contactor on the car that connects the two big power pins directly to the battery after the handshaking is done.

The Tesla plug is going to do the same thing, except the two big pins are also used by the onboard charger (which eliminates the need for extra pins). They just need to have the contactor be able to switch between the two (and maybe the third option too of being disconnected from both). There is no need for a separate connector (the main reason why Tesla decided to build their own socket).
