I am currently reading up on high voltage electrical systems for my ev.
I came across talk about the risk of arcing your electrical components.
What does this mean?
Any help would be greatly appreciated.
Thanks!

Think lightning on a small scale which can/will burn/melt metal and
other things. If you have a corded drill your can see what they are
talking about if you look through the vent holes at the end of the
drill while it is running. With AC current like in your home it
switches direction at a rate of 60 times per second. This means that
it is at zero volts 120 times per second. Because of this switches and
things rated for AC do not have to have as wide of a gap nor have to
be as robust as a DC switch. When the voltage goes through zero volts
the arc stops, on direct current, however, the gap has to get big
enough so the arc will quit. When an arc forms it ionizes the air
around it making the air conduct electricity more easily so the arc
has an easier time continuing.

I'm sure others will add more to this basic explanation.

HTH,

David

Imagine a green ball of plasma (what the surface of the sun is made of) a
few inches in diameter (green if you use copper wire, kind of purply white
if it's going off of steel).  If you have a current limited source like a PV
array, it's kind of fun to short it out and get a 300 or 500 volt, 10A arc
-- that'll make a ball about 3 inches wide before it extiguishes.  Batteries
are not current limited.... so are a bit more dangerous if unfused.  I've
once had a big bronze battery termnal vanish in a white flash and a ball of
smoke -- and I swore I'd never do that again.   Don't ever put yourself in
the position where you could short out a high voltage battery bank (proper
design, nonconductive tools, etc), and use properly rated components (DC
rated, not AC rated) so the components themselves don't arc.

Personal "Plasma Event" (was: High Voltage Arcs)

In reply to this post by Simon Burns-3
No matter what you read or how thoroughly you are instructed, it
seems like no one _really_ gets the proper respect for battery safety
until they personally experience a "plasma event".

I have lectured and instructed newbees about the safety precautions
told them repeatedly that "1000's of amps will flow" if you are not
very careful. They will still be careless with tools, nuts, bolts,
soldering irons, etc. no matter how many times I pull them aside and
say, "If this had touched that, 1000's of amps would have flowed with
a blinding flash. You need to really be careful and deliberate when
working with batteries."

         Then, they will finally do something stupid, like measure
the length of a high-power cell with metal calipers, or carelessly
touch "this" to "that", or drop a bus bar into just the wrong spot.
After their vision clears and they can hear once again, they will
universally say, "Oh my god! I had no idea that would happen!" They
finally get "religion" about safety procedures around batteries after
that. It seems to require an object lesson to fully appreciate the
true meaning of "1000's of amps will flow."

1) _Always_ wear those blue nitrile mechanic's gloves when working on
the battery pack or the high-current wiring of your EV.

2) Check for ground faults first, before you do _anything_ else.

3) Don't just "dive in" and go to work. Instead, carefully think
through every move you make before you pick up a tool or touch
anything. Be _very_ deliberate. Think about the "other" end of the
wire or the tool. Where could that bus bar drop? Where are you going
to put that bolt when you remove it? Where are you going to put that
tool down while you are hand-loosening that nut?

4) Take a few extra moments to tape up the metal surfaces of the
tool. Then cover surrounding exposed parts with a heavy cloth, rubber
matt, blue painter's tape, insulating board, etc.

Of course, you will ignore all these precautions until you actually
personally witness "1000's of amps flowing." :-)

thanks for the safety reminder Bill, we can't repeat this too often.  
I've added a couple comments ...

- or even better - lineman's gloves.  much thicker and rated for the big
HV ($40 grainger).  optional leather covers ($40).

- careful!  a quick wrap of electrical tape might not insulate HV.  
Better than nothing but maybe use thicker pipe insulation, rubber sheet,
etc.

One thing I am wanting to do for my Junior racer is get some of those plastic (composite) tools, like the composite ratchet and open
end wrenches.  Has anyone ever played with any of those?  Most of the stuff the Junior has to use does not take that much torque so
the plastic tools should be fine.  They are plastic handles with the metal inserts for the ends.  I saw some of the plastic ratchets
a while back but don't remember where to get them.  Does any one know?

I was just there and just checked it again. Try this:
www.cementexusa.com maybe you use a different browser. If that doesn't
work if you can take a 20mb file I can email you their pdf.

         You can't possibly handle ordinary tools with lineman's
gloves. You will drop nuts, bolts and bus bars with the resulting disaster.

         The blue gloves are not perfect protection, but like a
condom, they offer 99%+ protection. They don't interfere with your dexterity.

         You need some degree of protection, but if you wear thick
gloves to do ordinary work around your pack, you will have one plasma
disaster after another as you fumble tools and parts. The blue gloves
offer just that little bit extra that stops 99% of the "stupid"
shocks you will get when, for example, you accidentally brush your
arm against a terminal or live component while holding a wrench in your hand.

         You are not dealing with big volts. Ordinary tape works
fine. Tool dip works darn good as well. Heat shrink is nice for screw
drivers and ratchet handles. You are just trying to help keep metal
from touching metal when you do something "stupid".

I got it.  Google Chrome, Firefox nor IE worked on the links.  But Firefox allowed me to download the .pdf catalog.  So I got the
20M file..

Thanks. I'll take a look at what they got.  I don't need my Junior driver sparking crescent wrenches like I have done in the past
;-)

Holy schmolly.  Those are all steel tools.  I saw some composite wrenches at one time that were less than half the prices.  Granted
they aren't made to take the 200 ft-lbs the steel tools are made for.  But I only need a handful of ft-lbs rating for the electrical
components.  Thousands of $$ for a set is too much for my taste.  I need ala cartse pricing on a crescent, three allen wrenches and
4 or 5 box ends, and a 1/4" ratchet.

Yep, that’s them.  I'd probably buy those.  I need to look through their whole offering.  But if they have everything I need it
might happen.

Thanks

Anyone new to the EVDL who has never read the story of how John Wayland
earned his "Plasma Boy" nickname should read it, NOW.  

For one thing, it's a good cautionary tale : if you won't take care of
yourself, at least practice safe battery maintenance to keep your EV from
being turned into a cinder.  

For another, it's a highly entertaining read.

If you're short of time, I recommend the Reader's Digest Condensed version
here :

http://evdl.org/pages/plasmaboy.html

However, if you want the full flavor of the story (and you have a lot of
time), read the original full length 8 1/2 page version.  It has every last
little detail, including how John and his friends swarmed over an electric
dragster nearly ruined by fire and, in a bit over 16 hours, had it ready to
race again (and even looking decent).  Go here instead :

I have the Cementex "Battery Tool Kit" and it is very nice.  I don't
remember how much I paid now,  I did order it from one of my local
electrical wholesale houses and I don't think I had to pay full catalog
price.  The wrenches are steel with a 2 layer insulating covering such that
the inner color will show through if the insulation gets worn.  Then it
would be time to order a replacment but it will still work till it arrives.
The torque wrench is in inch pounds and looks a lot like my Snap-on one
although I don't see their logo on the handle.  The handle cover slips off
to make the adjustment on the wrench but it does fit snug enough that I
don't feel at all concerned about it coming off in use.  It all even came in
a small plastic tool box so they can be kept separate from the general
population of tools in the shop and can be taken as a kit to a job site.

I think the kit has open ends, ratcheting box ends, nut drivers, flat and
phillips screw drivers, short and deep sockets, a ratchet, extension, and
torque wrench.  The wrenches and sockets are in the 2 or 3 most popular
battery sizes, 1/2", 9/16", and maybe 10mm.  This is all from memory so the
catalog should be consulted for exact items.

respectfully,
John

That sounds pretty cool. The double layer insulation makes sense.  1/2", 9/16", 5/8", 11/16" and the 10mm are the most common on my
car.  The Enersys batteries have 10mm screws and the Albright Contacotrs are metric to but an 11/16" box end fits well enough and
doesn't damage the nuts.  The Junior would do with those but I have a lot of countersunk allen heads and the set screws for the
sprokets, brake hub and bearings take allens as well (7/64", 3/16", 7/32 and 1/4") and I can take that whole car apart (even the
motor).  I may need to find a distributor that can give a deal.
