[EVDL] Sidewalk EVSE solution

[Robert Bruninga via EV]

You can see my over-the sidewalk swinging conduit about 50% down this page:
http://aprs.org/AFM-EVs.html

It swings out at 7' when in use, but swings back when not in use.
I chose 7' because that appeared to be the lowest height of Awnings along
our main street for small shops that have them.

Re: [EVDL] Don't be a pathetic charge-mooching-thief> (get towed)

[Lawrence Rhodes via EV]

In San Francisco there is a law that says gutters go on the sidewalks(some 
places allow gutters to drain under the sidewalk to the street which would be a 
great place to run a wire) or in the sewer no connection to the curb so getting 
creative you could put the cord out a door or window and over to a street sign 
then down to the car.  This would keep pedestrians safe.  However if anyone 
complained it would be obvious.  You could get or build a cable ramp for 
wheelchairs and pedestrians.  Still obvious. You could used a planted tree with 
a cutout in the sidewalk to hide a conduit. All of these would get you a fine 
in San Francisco. So if you do any of these do it overnight. Lawrence Rhodes

Re: [EVDL] FW: A Message from Amazon Business Customer Service

[Robert Bruninga via EV]

Lets make sure to keep the email record (traceability back to my web page)
because we should not want one of these copies of the sign to then at
sometime in the future, claim copyright to their layout. And then we are
blocked from when we finally do find a low cost source.

Thanks.
The more signs the better.
I doubt it would ever come to that, because these signs are so generic,
but just something to remember.

It sounds like more than one of us is making progress on this, but without
unduly putting too much stress on one of us to become some sort of
shipping department on what in effect is a zero-sum EV charitable effort.

This week signs.com is trying (as possible) to duplicate the sign you
showed us at the link, and then I will order a couple.
I've also told them that others would be interested, so maybe they will be
able to make the finalized design available to others.

Also, some years ago I bought some quickly-self-designed t-shirts from
this place:

zazzle.com

I checked last night and they do seem to have some ability to design your
own parking sign, though I'm not sure of quality.

Re: [EVDL] V2H or better, (V2O)

I do think it would be worth considering to beef up the 120 Volt
plug output capabilities of many BEVs and PHEVs.  I don't know
if there are signficant drawbacks such as general wear and tear
on the vehicle battery, as is a concern in general with all V2x,
as I understand it.

Re: [EVDL] sumitomotire.com energy generating tires> frictional charging

[paul dove via EV]

It is not perpetual motion if the friction already exists it is just improving 
efficiency. 

Adding things that cause drag is defeated by conservation of energy. You lose 
more than you gain.

Alas; that's modern journalism at "work"...

I will say that it would be great if there was *some* method to eliminate the 
expensive periodic replacements of the TPMS senders because their battery ran 
down. It is idiocy / flagrant profiteering to require that the tires be removed 
to replace them!

Not at all. The tires are producing the static charge whether you want 
it or not. If you leave it, it will dissipate as heat. If you harvest 
it, you can use it.

Correct.  However, following the main article, Bruce's post references 3
more articles, all of which suggest that energy recovered from flexing tires
could somehow be used to charge an EV's battery.

At least their headlines say that.  I'll admit, I didn't actually read the
articles.  Life's too short.  :-\

[EVDL] (more) pack exploded blowing garage door across street: ... fire in Île-Bizard.ca

Despite Île-Bizard explosion, expert says electric cars safer than others
July 31, 2019  CBC

Even though an electric car battery exploded in Île-Bizard last week,
blowing a garage door clear across the street, there is no reason to doubt
their safety, says the federal government's leading battery scientist. 

Dean MacNeil, head of the battery testing team at the National Research
Council of Canada, said evidence suggests electric cars are safer than ones
fuelled by diesel or gasoline.

But safety issues with traditional cars don't attract the same amount of
attention. 

"I'm sure everyone's seen a car on fire on the side of the road and not
really thought much about it," MacNeil said. "But if it was an electric car,
there would be a lineup of people taking pictures and showing it on the
internet."

Electric car batteries basically operate the same way as a cellphone battery
does, he said. 

The main difference is that they're larger. Whereas a cellphone battery is
the size of a credit card, an individual battery cell is as tall as a sheet
of paper and about half-inch thick.

Those cells are stacked together to form a battery pack, which differ based
on the range, performance and price you want to pay for the vehicle.

West Island explosion still being investigated

The electric car that exploded in Île-Bizard on July 26 blew the door off
the garage and sent it across the street.

Transport Canada is working with the Montreal fire department and the car's
manufacturer, Hyundai, to determine what happened.

"The details that will be gathered will help determine the next steps, and
whether a full defect investigation is warranted," said Mélany Gauvin, the
director of operations at the federal transport ministry.

MacNeil said what could have happened may have been as simple as a small
mechanical defect inside the battery cell.

He speculated that the warm weather on Friday may have sped up the chain of
events that led to the explosion, but the heat itself was unlikely the
primary cause. 

MacNeil said there are things that need to be improved with electric cars,
but that overall, safety isn't a major issue — he has two children who ride
in his electric car and he isn't worried about them.

Hyundai Canada would not comment on the explosion but would "push to fully
understand the issue as quickly as possible," said public relations
coordinator Jasmine Law.
