Re: [EVDL] Hyperbole from "Infrastructure Industry"

We just had some research done over EV charging opportunities in Finland.

There's a unique situation here since we can find about 1,5 million
sockets (230VAC/10-16A) outside by the parking lots. They have been
kinda mandatory for ICEs when they are iced. System has been
developing over past 30 years. They still do it cheap. Pole, cable and
socket-box costs about 200 =80. New socket base maybe 15=80. New heater
cable 25=80. I love the trend !

Also people have used to plug in. All winter. Every year. A bit over
2 million cars on the roads. That's plenty of plugging in harsh
conditions (very cold plugs get reheated once a day). Average Wh
pulled from the plug every morning for the heating.. I'd say 1,5 to 4
kWh. I do know some idiots who keep the car heated over night too.
I've seen 12 kWh going in over night to neighbours cabin heating
'experiments' (sigh)

Safety then ? How many plug-in deaths a year against maybe 100 million
plugging ? zero.

During past 10 years then ? NONE.

So .. go figure.. how much more safer is the new plug ??

100 mile pack, overnight charging (sleep charge) and wife on a good mood..

what else would man need ???
