The DC Fast Charging standard first out of the Gate - was CHAdeMO ~ 50 kW. This was followed - more or less - with Tesla presenting to the world - Their New Supercharging Stations ~90-98 kW. Recently I have seen information on newer CHAdeMO chargers at lower Fast Charge Rates of 20-25 kW - From Fuji, and slightly Lower from Nissan's new QC (Quick Charger) at 44 kW. CHAdeMO Association - Home. So that makes 3 DC Fast Charge levels: 20 - 25 kW - CHAdeMO, 44 - 50 kW - CHAdeMO, and 90 - 98 kW - Supercharger While there is a response from Tesla Motors that the Japanese Model S will have access to the CHAdeMO network, there are already 160 of them in USA (+ 2 in Canada), and the 44-50 kW Rate of them should be fine - even for the 40 kWh Model S, considering the 60 kWh Model S can handle the Supercharging Network when it has the option installed - and it is charging the whole pack at about 1.5 C to 1.63 C (C Rate = the power compared to the pack capacity), so a 50 kW CHAdeMO Fill would be just 1.25 C for the 40 kWh pack, So that would be very easy on the pack, compared to the Supercharger pushing 90+ kW at the 60 kWh Pack. (I have read comments - that showed a Model S Charging - with an image of the Volts & Amps - totaling out to 98 kW! that is only at 1.153 C for the 85 kWh Pack - but - as said above - it would be as high as 1.63 C for the 60 kWh Pack. So - it would seem like Tying the 40 kWh Model S down to just a max of 20 kW while at home, and maybe 10 kW while out - via the J1772 Network - would be a bit of an unfair strike on the 'baby' of the fleet, and that giving it (an it's big brothers with 60 or 85 packs) access to the already much bigger CHAdeMO networks - goes a long way to making the car - plug-able anywhere! Plus - "In fact, the geometry of CHAdeMO connector is designed to allow for 200A" This Further States - "20KW units require much less output power and can be an ideal charging solution in certain urban or commercial areas" - indicating the breadth of the Standard, if not so elegant. Sure the Superchargers are the King of the heap, but if not in with the king - are we then stuck to just the Pawns? The West Coast Electric (Green) Highway is already well suited to giving all Model S cars access to DC Fast Charging at up to 50 kW - West Coast Green Highway and there may also come choices with the big SAE Plug too. "More than 40 DC fast chargers are open to the public in the Pacific Northwest." Estonia - is opposite to America - it is now Infrastructure Heavy - and Electric Car Light - with more CHAdeMO Chargers installed - than are in America - at 165! Japan saw an increase of more than double the amount of EV Use on a small 350 Km Tokyo to Nagoya route - just by moving from 2 CHAdeMO Fast Chargers - to 6 unit Locations. Reducing the Distance between Superchargers - to the Distance a 60 kWh Model S can drive at least at 65 Mph with the Heater on and the Outside temperature at Freezing - (167 Miles Max, Under 150 Miles for Comfort) is the beginning of opening up Supercharger Travel for Model S Owners of both levels. Giving them all (Not just the Japanese deliveries) access to the current CHAdeMO charging infrastructure completes the Loop of making the car become a Go-anywhere EV! This is what we all look forward to!
