Hi Jay, It has been over 2 years since a typical SF girl came to the EV Rally at DeAnza and since she did not want to have the hassle to plug in when she arrived and did not want to wait an hour to pick up enough charge at the available L2 chargers, she called AAA to have the tow truck come to give her a charge in half an hour, since it charges at double the rate of L2. I forgot to ask how the charger generates its power, whether it has its own engine like a fancy backup generator, or that it has a PTO from the truck engine. There is no truck with less than 100kW engine power, so if it would be PTO then there is not a limit on the engine side, but maybe on the generator head and electronics. I presume however that they took a standard 12kW genny and added the electronics and cord to turn it into a Chademo station. Then it would be more of an issue with the size of the genny.

Anyway, not my > decision. I imagine this is because the truck engine is operating as a 12 kW generator (or perhaps they have a dedicated 12 kW generator on the truck?). Carting around something in a tow truck that can supply 400V at 100Amps isn't easy...
