Last week, General Motors’ own blog, Fast Lane, put out a list of ten
workplace charging etiquette tips, now that the technology is catching on.
In fact, according to GM’s own EV infrastructure expert, Britta Gross, EVs
begin to sell much faster once others become aware of how easy it is to
charge their cars at work and at home.
General Motors leads by example, with more than 400 EV charge stations
available for both employees and visitors.
In case you’re new to the world of EV workplace charging, we’ve summarized
GM’s workplace charging etiquette tips for you below:
Always be safe when charging. Take care of your cord properly at all stages
of the process, tucking it under your car during the charging so that others
do not trip or drive over it. Once you are finished charging, wind the cord
onto its holder and tuck in any excess. Also important: do not let the cord
contact the paint of other nearby vehicles.
Only use EV spots if you have an EV. This one seems self-explanatory, but in
case you were wondering, you should not use a charge spot for a plug-in
vehicle as a parking space for your gasoline-powered car. Makes sense,
right?
Adhere to all signs. Obey all signs like other drivers must. For example, do
not park in a handicapped spot just so you can get access to a charger.
Don’t charge just because you can. If your car will be fine on the way home,
do not waste the workplace’s electricity, and, more importantly, don’t use
up a charge spot that someone in need could use.
Get in line. There is no special treatment. These stations act on a first
come, first served basis. If you’re consistently missing out on a spot when
you get to work, try coming in earlier.
All EVs are equal. You might be driving a pure battery electric vehicle, but
that does not give you the right to unplug an extended-range electric
vehicle just because you know that the car has a backup gas engine.
Ask for a charge. If you need to charge your car but someone else is
currently charging theirs, it’s okay to open your charge door and ask them
to plug your car when they are finished.
Hands off other EVs, unless they are finished charging. The rule of thumb is
not to touch another person’s EV while charging. If it is very clear that
the car is fully charged, then it is okay to remove the plug and place it
into your own. If you do so, you must remember to close the charge door of
the other vehicle.
Charge like lightning (ba dum chh). If you can, only remain in the charging
spot while actually charging. As soon as you are finished, say sayonara and
let someone else begin to charge. If you can’t wait with your vehicle, you
can use the OnStar Remote Link App to let you know via text or email when
your car is finished charging. Cool, right?
Don’t abuse your company’s workplace charging stations. This is a privilege,
not a right. If your company is cool enough to offer workplace charging
stations, be grateful.

HI-RES GALLERY: 2014 Fiat 500e
]
A recall has been issued for certain 2013 and 2014 Fiat 500e electric cars
to address the possibility of coolant leaks.
The recall will correct an issue with the affected vehicles' Power Inverter
Modules, which may contain faulty cooling plates that can leak coolant onto
high-voltage circuitry.
This could cause a service fuse to blow, which would lead to a loss of power
while driving.
Fiat dealers will replace the Power Inverter Module free of charge; the
process of recalling the cars and replacing the part is expected to begin
later this month.
Fiat 500e electric cars affected were built between September 24, 2012 and
April 4, 2014--a total of 4,141 vehicles altogether.
This is the second major recall for the plug-in Fiat, a compliance car
offered for sale or lease only in California.
Last year, the 500e was recalled after only a few months on the market over
potential half-shaft failures. The half shafts were prone to separating
while driving, leading Fiat to replace fasteners for the inboard half-shaft
joints on affected cars.
Owners can contact Fiat at 1-888-242-6342. The reference number for this
recall is N51.
In addition, the recall notice can be found at the National Highway Traffic
Safety Administration's Safercar.gov website under ID number 14V235000.

Re: [EVDL] EVLN: GM's Workplace Charging Etiquette Tips ...
If I remember correctly, Mike's work is at the hp in Boise, ID. His
description of their inter-coworker cooperation and communication reminds me
of what hp was when I worked for them for 25 years. Its nice to know his
site still seems to operate using Bill and Dave's old-school methods,
whereas sites near hp Corporate in CA abandoned that long-ago when I worked
under CEO Carley's reign.
But large companies that don't have that 'on-the-same-page' attitude and
approach, have employees that are strangers and aloof to each other. Those
plugin drivers act like they are using public charging, where they do not
care about the other driver.
This becomes especially true the more EV charging there is at a site, and
when there are visitors using that EVSE. At Facebook in Menlo Park, CA
http://a6b6a4d850da023e34c0-ffd458871468d7801be60d93d5d79b26.r30.cf2.rackcdn.com/45930.jpg
there is a fair amount of charging around the former Sun-Microsystems/Oracle
site buildings that an employee would likely not know the driver of the
plugin vehicle next to them. This is going to become more common as more and
more EVSE is installed at work and out at public locations.
Here are some examples of large quantity EVSE installations:

Houston's Tranquility Park Garage
http://www.cnet.com/news/google-we-have-largest-ev-charging-network/
Google says it will have 450 free charging stations on campus ...
There are several other multiple-EVSE sites, but I think that is enough to
make my point.
...
What I found interesting about GM's newswire release to the media, was their
late-to-the game effort to jump on the EV bandwagon. As if all their
million$ of dollar$ to fight against plugins should be forgotten, and now
they are the Good-Guys (?!?).
Particularly the sentence stressing that all EVs (which they still insist
the Volt plug-in-hybrid is) should be treated equally: do not unplug a pih
because you know it can run on fuel.
If a pih driver wants to use their pih in electric mode as much as possible,
I can see that point. But how does anyone know what a pih driver's habits
are. Clearly, a drained EV must get charging.
[Please lets not start a flame war on who should get what]
What I see is there is no established communication method between plugin
drivers to talk to each other and see if what each driver's needs are. That
is what I hoped GM would make happen. But all we got was lots of words that
whitewash GM to look good, and the public to feel-good about their belated
EV efforts.
Perhaps there needs to be a next-gen EVSE that is smart enough to know who
to ding the use-fee to, read the plugin's recharge-time desire, and adjust
that fee accordingly.
The EVSE owner may also want to sort out who 'needs a charge' vs who 'wants
a charge' using those different rate fees.
Perhaps the next-gen of EVs would have an EVSE interface screen on their
infotainment system that would let them select what charge to get (how
co$tly), and give data to the EVSE of what type of plugin it is, and how
badly it needs a charge:
-EVs wanting a higher/faster charge rate would pay more
-pih with on-board fuel would pay more
-EVs only wanting a low-n-slow and or an interruptible/V2G charge would pay
less
-etc.
Something has to be done to communicate who 'needs' what, else charging
situations can get nasty/abusive.

Re: [EVDL] EVLN: GM's Workplace Charging Etiquette Tips ...
I work for Qualcomm at the mothership in San Diego, and as a result we
have several thousand people all in the same area. Being a high-tech
company, we have a LOT of EVs. Of course, we don't have a lot of
charging spots. The good thing is that we also have a wiki, a mailing
list, and a lot of well-informed people to help share the charging
spots. The only company edict we have is that we are allowed to charge
wherever there is a plug and a valid parking spot. The rest we have
come up with on our own, similar to what Mike has. Surprisingly, the
facilities people are very supportive - we have an email list to tell
them when a circuit breaker has tripped (too many EVs on a level 1 plug).
Bill and Dave still live on, I like to think. :)
Cheers, Peter

[EVDL] Exploding cell
Kaboom goes the cell! Was testing a battery module from my Prius on a battery analyzer. The test plan begins with a several minute no-load, then a 1C load for up to 1 hour, then a several minute no-load, then a charge at 1C until peak voltage is detected. After 3 minutes, a cell exploded that could be heard all over the building. Best I can tell, there was a less than perfect connection to the battery terminal. The initial 1C load only lasted 3 seconds (when it determined that the low-voltage had been reached). So then, 10 minutes later it began a 1C charge (on what was a full battery). And we all know that charging a full NimH battery will explode. Lesson learned. 1) Hang around and WAIT for the initial discharge and WATCH that it is going correctly before leaving the test. 2) Always assume a battery may explode and do testing where it will do no damage. Programmers: When programming battery analyzers consider a bad connection on the DIScharge cycle that might give an erroneous indication of a discharged battery and fault the test. Do not then continue to the charge cycle. Bob, WB4APR -- next part -- An HTML attachment was scrubbed...

Re: [EVDL] [EVADC Listserve] Exploding cell

Re: [EVDL] Exploding cell
Welcome to the club! If you have never exploded a battery you have really missed out. My charger was just about finished up around midnight one night a few summers back. My truck was in my driveway out in front of my house. I did not have my battery box vented well enough and something must have created a spark. I think I shook the whole cul-de-sac with that one. It was a very large boom. It took me a few days to find the lid of my battery box. It ripped off the hinges and blew up over my 2 story house and was hidden on the back side of my roof. A few cells got ruined, but for the most part I was just able to put everything back together and no real damage was done. I'm glad I did not have my truck in the garage, and even now do not charge in the garage. I figure if I ever make another mistake and explode things or catch something on fire, sitting in the back of my truck in my driveway is a fairly safe place for my battery to have problems. damon Date: Wed, 18 Jun 2014 08:54:29 -0400 To: ev...@yahoogroups.com CC: ev@lists.evdl.org Subject: [EVDL] Exploding cell From: ev@lists.evdl.org Kaboom goes the cell!

Re: [EVDL] [EVADC Listserve] Exploding cell
Was the module you were charging in a pack? i.e. was it compressed mechanically by the end plates? There modules will explode if you charge them without pressure being applied to the sides. I have also seen modules that are properly mounted that have had an internal explosion in a dead cell. The cell it's self was totally dry, all the water having been converted into hydrogen and oxygen. My 4 Priuses are all the NHW10 original Japanese only models with D cells. I have done a lot of work on these and have never seen a exploded cell, all that happens to these is that the cells leak electrolyte if they get to hot. -Original Message- From: EV [mailto:ev-boun...@lists.evdl.org] On Behalf Of Robert Bruninga via EV Sent: Thursday, 19 June 2014 3:01 a.m. To: ev...@yahoogroups.com Cc: ev@lists.evdl.org Subject: Re: [EVDL] [EVADC Listserve] Exploding cell The prius has 28 modules, and each module (about the size of a paper back book, only taller) has 6 cells.

Was testing a battery module from my Prius on a battery analyzer. The test plan begins with a several minute no-load, then a 1C load for up to 1 hour, then a several minute no-load, then a charge at 1C until peak voltage is detected. After 3 minutes, a cell exploded that could be heard all over the building. Best I can tell, there was a less than perfect connection to the battery terminal. The initial 1C load only lasted 3 seconds (when it determined that the low-voltage had been reached). So then, 10 minutes later it began a 1C charge (on what was a full battery). And we all know that charging a full NimH battery will explode. Lesson learned. 1) Hang around and WAIT for the initial discharge and WATCH that it is going correctly before leaving the test. 2) Always assume a battery may explode and do testing where it will do no damage. Programmers: When programming battery analyzers consider a bad connection on the DIScharge cycle that might give an erroneous indication of a discharged battery and fault the test. Do not then continue to the charge cycle. Bob, WB4APR __._,_.___ -- Posted by: jo reyes jomre...@gmail.com -- Remember- DO NOT FORWARD messages from this listserve! Thanks!

Re: [EVDL] Exploding cell
Cell voltages actually drop after they are fully charged, less so at high rates like the 3C of the in-car equalisation charge of the early prius , charge termination often involves detecting a -delta V. the Ni-mih cells in a Prius often suffer from differential high self discharge currents and get badly out of balance, correcting this involves a 3C charge of a few times the capacity with a lot of heat generated. -Original Message- From: EV [mailto:ev-boun...@lists.evdl.org] On Behalf Of Lee Hart via EV Sent: Thursday, 19 June 2014 4:11 a.m. To: Robert Bruninga; Electric Vehicle Discussion List Subject: Re: [EVDL] Exploding cell Robert Bruninga via EV wrote: Kaboom goes the cell!

To: ev@lists.evdl.org Date: Wed, 18 Jun 2014 11:55:38 -0700 Subject: Re: [EVDL] Exploding cell From: ev@lists.evdl.org Welcome to the club! If you have never exploded a battery you have really missed out. It was a very large boom. It took me a few days to find the lid of my battery box. It ripped off the hinges and blew up over my 2 story house and was hidden on the back side of my roof. :-) :-) Wow..! - Glad to hear that it went well, and that no heads or other important body-parts was lost in the learningprocess... So, lesson learned I guess. Hehe. Yes, definitely lesson learned. I knew for years that my battery box was not sufficiently ventilated and that hydrogen could be accumulating, but I never had a problem until that night. So not only did I learn to be sure and ventilate my batteries while charging, I also learned that just because you have been doing something one way without problems for an extended period of time, does not mean that it is ok especially when you know there is potential for problems. That is one of the values of a list like this. We can learn from other peoples mistakes and not have to make them ourselves. I am now much more careful to listen to others safety precautions and implement them before having problems of my own. Just the other day I had a problem with a laptop battery. It looked to me like it had just been run down too far and that my laptop would no longer charge it. I know that internally it is just a few lithium cells in series, so I took it out to my garage and forced a charge through it with my hobby charger. I know from others that lithium cells with problems can burn and that once they start burning they are next to impossible to put out. Because of this, I placed the battery in an old frying pan I have in my garage so that if there was any damage that could cause a fire it would be contained and safe. Fortunately there were no problems, and after 15 minutes of charging the voltage was high enough that my laptop was happy with it again and all is now well. I knew to be cautious and what precautions I should take because others shared their mishaps with me. damon -- next part -- An HTML attachment was scrubbed...

Re: [EVDL] EVLN: 2015 Kia Soul EV will be sold in CA, OR, NY, NJ MD (video)
Not planning to sell it outside of compliance states seems to indicate that
it's a compliance model, to me. They did say that it's in states with
significant EV infrastructure... whatever that means (I figured that
virtually everywhere in the US has electrical outlets -- what more do you

Hi Bruce,
I was wondering how do we know they plan for the Soul EV to be a compliance

compliance vehicle a pejorative we bestow after they sell them in low

From newswire:
The dash of the Soul EV features one of the most advanced screen
technologies available in the world, OLED. OLED, Organic Light Emitting
Diode technology is perfect for EV usage as it uses a fraction of the
electricity of standard LCD screens and it produces virtually no heat.
That
means less electricity to power your dash, and more power stays in the
batteries.
Their statement is not inaccurate, but the fact they mention it, like you
say, lends too much emphasis (the writer's EV fears) on saving energy.

The Soul EV is like all the other compliance cars selling a
non-purpose-built EV: an ice model retrofitted by the factory. The Soul
ice
has been around for a while
http://en.wikipedia.org/wiki/Kia_Soul
The above wiki URL says that the Soul EV will have DC L3 charging, so I
will
assume that is CHAdeMO. Which means if you get a Kia Soul EV, you can use
the vast amount of CHAdeMO L3 EVSE
