I think this quote is particularly significant:
" We are now testing a 25kW, 150A unit (see pics below). It will have CANbus interface and DC Fast Charge protocol built in so that you can use it with production electric cars, too (e.g., make your Leaf charge in 1 hour from your house electrical service!)... "
I think that means that the LEAFs (or iMiEVs) with DC fast charge port could get a 17-19 kW charge from 70-80A HPC or J1772 EVSEs from a $600 component price device. Now you could mix the CHADEMO DC fast chargers with AC medium-fast chargers on a road trip. The LEAF could therefore handily beat Kevin and David's End-to-End time (assuming they had suitable adapters and were allowed to use the HPC network).
Perhaps more importantly, boxing up this charger and adding the right charge connector, makes a medium power CHADEMO for $600 of components. Add those alongside the HPC network and at a few other locations and the UK is covered for LEAF and iMiev charging and travel at the same speed as current Tesla Roadster roadtrips. EDIT: David Peilow has tweeted this is 40 locations. Might therefore need 2x the cost of the Tesla HPC network to support all iMiEVs and LEAFs for travel at the same rate as the Roadster.
If Eberhard is correct in his assumption that they can be ganged together, then a 50kW CHADEMO working off a 3x63A 3-phase supply is under $2000 in componentry.
Obviously this analysis completely ignores regulatory, certification, insurance, labour and licensing (for the CHADEMO protocol) costs or any profit element. I'd like to hope that we could still be looking at sub $3000 in volume. David Peilow's amazing work developing the UK Tesla HPC network (with a little help from his friends
) suggests they could be installed for around $500-1000 each (when intelligence rather than brute force is applied*).
* Brute force: choose the parking spot then dig trenches and run hundreds of meters of cable to it. Intelligent: look where the high power circuits already terminate or originate near a parking spot, then use that one
