FREMONT, Calif. (KGO) -- The driver of a Tesla Model X SUV survived what
appeared to be a high-speed crash this morning in Fremont after smashing
head-on into a tree on Paseo Padre Parkway near Thornton Avenue. Fremont
Fire Battalion Chief Gary Ashley said the driver was able to free himself
from the wreckage. The vehicle caught fire and suffered extensive damage to
the front third. No other vehicles were involved.

This happened shortly after 7 a.m. on Monday. Battalion Chief Ashley said it
was not immediately known what triggered the fire in the electric vehicle,
but first responders instituted tactics to fight a battery fire by pouring
3,000 gallons of water on the white SUV. They also used a thermal imaging
camera to detect to monitor whether the batteries might cause a second fire
to erupt as has happened in previous Tesla crashes. After more than two
hours, fire personnel deemed it was safe to move the wreckage on a flatbed
tow truck where the Tesla was isolated and monitored for a second fire at a
tow yard.

Tesla issued this statement after ABC7 News contacted the company: "We have
been in touch with the local authorities to learn the facts of the incident
and offer our full cooperation. The damage sustained by the vehicle is
indicative of a very high speed collision, which can result in a fire in any
type of car, not just electric vehicles. Despite the significant impact, we
understand that the driver sustained only minor injuries and has been taken
to the hospital for further evaluation. We are glad that he is safe."

The Model X is registered to Brian Morton. Tesla would not confirm whether
he is a Tesla employee.

This is the second incident involving Tesla in three days to which Fremont
firefighters have responded. On Saturday night, a fire erupted in a
fenced-in area of Tesla's Fremont auto plant. Battalion Chief Ashley, who
also was at that incident, said that it was difficult at first to know what
was on fire until Tesla supervisors arrived. The Fremont Fire Department
dispatched 25 personnel, including its entire hazard materials unit, to that
incident.

When asked for a statement about the Saturday night fire, a Tesla
spokesperson would only say it was contained, there were no injuries and
there was no impact to production.

"We were able to determine that some battery modules were involved, not so
much a complete pack but modules that were disassembled as I understand it
for recycling," said Battalion Chief Ashley. Once that was determined,
Ashley said Tesla provided a forklift and bins which they filled with water
to submerge the battery components ...

https://www.google.com/search?q=nimh+ovshinsky+sold+gm
 ... Ovshinsky ... decision to sell to GM had been naive ...

Long before the internet
https://en.wikipedia.org/wiki/History_of_the_Internet#Rise_of_the_global_Internet_(late_1980s/early_1990s_onward)
I would read through tons of paper media on Ovshinsky's efforts to make
Ovonic (NiMH baterry) a success.

I differ from Willie, IMO, ALL automakers & oil/fossil were in cahoots to
maintain their incessant ice profit orgy (not just GM, though they are the
worst).

(section of Willie's page link)
https://en.wikipedia.org/wiki/Patent_encumbrance_of_large_automotive_NiMH_batteries#General_Motors_and_the_US_Auto_Battery_Consortium
 ... Ovshinsky stated that in the early 1990s, the auto industry created the
US Auto Battery Consortium (USABC) to stifle the development of electric
vehicle technology by preventing the dissemination of knowledge about
Ovshinky's battery-related patents to the public through the California Air
Resources Board (CARB).

According to Ovshinsky, the auto industry falsely suggested that NiMH
technology was not yet ready for widespread use in road cars. Members of the
USABC, including General Motors, Ford, and Chrysler, threatened to take
legal action against Ovshinsky if he continued to promote NiMH's potential
for use in BEVs, and if he continued to lend test batteries to Solectria, a
start-up electric vehicle maker that was not part of the USABC. The Big
Three car companies argued that his behavior violated their exclusive rights
to the battery technology, because they had matched a federal government
grant given to Ovonics to develop NiMH technology. Critics argue that the
Big Three were more interested in convincing CARB members that electric
vehicles were not technologically and commercially viable.

In 1994, General Motors acquired a controlling interest in Ovonics's battery
development and manufacture, including patents controlling the manufacture
of large NiMH batteries. The original intent of the equity alliance was to
develop NiMH batteries for GM's EV1 BEV. Sales of GM-Ovonics batteries were
later taken over by GM manager and critic of CARB John Williams, leading
Ovshinsky to wonder whether his decision to sell to GM had been naive. The
EV1 program was shut down by GM before the new NiMH battery could be
commercialized, despite field tests that indicated the Ovonics battery
extended the EV1's range to over 150 miles ...

Darryl cynicism is warranted. Though we (the public) can't do much about it,
we should keep our eye of those fat-profit-takers, and scream bloody murder
(on the internet) when they step out of line.

Re: [EVDL] EV familiarity

2019-02-18 Thread Michael Ross via EV
The issue of wire size is ALWAYS dependent on what sort of current MAY
occur even in a fault condition. The wire must be increased in cross
section if there are heat retaining conditions such as conduit, insulation,
limited possibility of convective cooling.

So you don't size the wire based on an assumption of a balanced load, you
figure out what faults may occur and what breakers control the circuitry.
If you are uncertain you up the wire size, you do not cost reduce the
system and down size wiring on a guess. ..

I am not going to comment about a system I cannot see, anymore than a
competent doctor would diagnose a patient without seeing them.

Please correct me if I'm wrong, but I'm pretty sure it was even before that.

I may be remembering with an accent, but I think Ovshinsky sold the NiMH 
rights to GM, naively thinking they'd use NiMH in EVs.  They did fit NiMH to 
a few limited-production EV-1s, but they also slapped capacity restrictions 
on them so that no other manufacturer could be licensed to produce EV-size 
batteries.  Texaco then bought the rights from GM and maintained the same 
restrictions.  

We could have had good, usable production EVs long before we did. Look at 
how NiMH performed in the first-generation RAV4-EVs and (especially) the 
prototype Solectria Sunrise.  Also note that Toyota and Panasonic were sued 
for violating the licensing terms.  

I don't think it's unfair to say that Ovshinsky's cashing out to GM may have 
delayed the introduction of viable mass-production EVs for at least 20 
years.

I don't have a copy of the NEC handy, and I'm not a code expert, but IIRC

Re: [EVDL] EV familiarity

2019-02-18 Thread EVDL Administrator via EV
I'm not a code expert, but as I understand it, in the addition to what Jay 
Summet said, the NEC generally prohibits connecting either 15 or 20 amp 
receptacles to a 30 amp branch circuit.  Receptacles must be 30 amp.  The 
fact that you're allowed to connect 15 amp 120v recepts to a 20 amp branch 
circuit is kind of an exception already.  

What you're doing sounds like tap conductors.  There's a whole list of rules 
for tapping a 240v feed for lower ampacity 120v circuits.  See here:

https://www.mikeholt.com/mojonewsarchive/NEC-
HTML/HTML/FeederSecondaryTapRules~20020326.htm

https://v.gd/Nosfgd

A much easier way to do this (fewer, less complex rules), and more 
convenient for the user if a breaker trips,  is to install a small rainproof 
subpanel at the charging location.  You would then use that to supply 
separate breaker-protected 240v and 120v circuits for charging.  

Ground and neutral must be separated at all subpanels (requires a 4-wire 
feed).  The receptacles must have heavy duty in-use covers.

I believe there is (or used to be) a code exception that allows a size 
smaller neutral (12 vs 10, 4 vs 2, etc) feeding a subpanel if a load 
calculation shows that the 120v loads will be approximately balanced.  I 
don't think that you could show that in this instance, so it probably 
doesn't apply, if it even still exists.

But -- NOTE WELL -- all this is moot unless you're a licensed electrician.  
Maybe you are, I don't know, but the fact that you didn't know what the NEC 
said about this makes me think that you might not be.  

It's illegal for an unlicensed person, no matter how knowledgable, to 
perform electrical work in or on a public building such as a church.  You 
can't even work on a rental dwelling that you either own or rent.  You're 
only allowed to work on the wiring in your own owner-occupied house, and 
then only with a permit.
