TEPCO/CHAdeMO Level III "quick" charging station/connector

[doug]

The article mentions quick charge socket being capable of 50 kW. Is plug design proprietary?

A little more on that connector and the charging station:

Here's a 2008 presentation by TEPCO on those quick-charging stations.

Specifications
-Type: Switching type, constant current power supply
-Input: 3-phase 200V
-Maximum DC output power: 50kW
-Maximum DC output Voltage: 500V
-Maximum DC output Current: 100A

Explains the confusion with the i-MiEV quick charge connector. For some reason Mitsubishi keeps quoting the input of the charging station rather than what the car sees.

Interesting post in EV Charger Maps for Vacaville

Saw the new TEPCO fast charger. I could pull out the connector, but there seemed to be no power to it yet, not that I had anything to plug it into anyway.

Some photos of the Vacaville install ...

Maybe. I am trying to get more info. I thought though that all the early deliveries (at least the "public" production ones) would have the fast-charge port disabled (initially at least).

The nation's first public DC fast charger (49 kW) was dedicated this morning.

Wonder why it only appears to be supplying about 24 kW here.

The batteries do not charge linearly so the power output will vary while charging.

Also, the charging speed typically given for the iMIEV is ~30 minutes for 80% or ~26kW.
