One of our club members got a Magnecharger and has some trouble with it. This 
is what he has encountered - 

I wired up the charger to 240 VAC.  Turned on the breaker.  The unit appeared 
to be energized.  I inserted the wan into the charger that goes on the car.  I 
measured the voltage at the charger output and it was 0 VDC. The pedestal 
charger has a cable coming out of it.  The cable looks like a control cable.  
What is the function of this cable.  A system wiring diagram would be nice a 
set of schematics would be better.

Can anyone help him?

TIA

Man, I gave back the loaner scooter last week (mine has a cracked
frame) and now the EVDL is down (getting a makeover?)

This must be what withdrawal symptoms are like. ;-)

Hi all,

So, I was thinking, instead of having a balancer that
bleeds strong cells during discharge, wasting the energy, how about a
balancer that taps the strongest cells in the pack to power the 12V
system? Maybe with a 24-12V DC-DC converter.

It would maybe
every minute, find the highest voltage cells, and switch the
connections to those high cells using relays. Maybe divide the pack up
into 24V subpacks, and tap into those, it would keep each 24V subpack
in balance. For a 312V pack, you'd need 14 relays, maybe with 30A
capability? The cells in each 24V subpack would not be balanced during
discharge, though.

Or maybe every 30 seconds, if minute is too large of a unit.

                                  - Tony

I have been running experiments trying to find a good home for a few hundred 
NiMH F cells that came out of a friend's EV project.  He did not have a good 
BMS and his battery setup ended in a fire that damaged about half the cells.  I 
am in the process of sorting through and trying make something of what is left.
   
  So far, I have discovered:
   
  1. These particular 13 AH F cells do not do very well in high rates of 
discharge.  They were originally fused at 40 A, but I don't feel good about 
taking these particular (now used) cells above 2C (26 Amps).  I am concerned 
about cycle life and overall performance at discharge above 2C.  This is just 
my opinion on these used cells.  New ones may be a lot better.
   
  2. The cells are "nearly impossible" to charge repeatably and reliably in 
parallel.  Even at very slow charge rates, with attempts to keep the max 
voltage below a critical value, I can't get good consistent results.  If you 
"fully discharge" them - down to about 0.9 V / cell and then try to put in a 
constant current for a fixed time period, it may give some fair to poor 
results.  Beyond that, I have had no luck trying to charge them in parallel.  I 
thought just putting a 13.2 V constant voltage supply across them and letting 
them sit would charge them.  Well, the experiment did not work well.  At least 
not the way I did it.  I tried just charging them with a lead acid charger at 2 
A rate.  Unless you accurately know the initial state of charge and use a 
timer, that doesn't work well either.  I also wanted to limit surge current 
between the strings with polyswitches, but they don't sell ones rated for that 
low of a current.
   
  3. That all means that charging is a very serious issue and expensive, bulky 
and heavy to overcome.  All I can come up with as a good reliable solution is 
12 individual small 1 A smart NiMH chargers for each of the 84 cell strings.  
That is one 1 A charger per each group of 7 cells.  These chargers would have 
to be very inexpensive, small and light weight to make this worth while.  I am 
yet to find such a solution.  Also, the system is a reliability nightmare to 
deal with a failure on any of those many many connections.
   
  4. Discharging seems to be no issue.  Simply put a diode and 13 A polyswitch 
in series with each string.  They can't "cross charge" that way and the output 
is limited to 1C average and about 2 C peak, which is what I wanted.  I don't 
know how long the polyswitches will last though.  They may be a consumable in 
this setup.
   
  5. Power density, even with all the mechanical "stuff" to hook the cells 
together and mount them in the car.  I'd say at least 30-40% better than AGM 
lead acid.  Maybe 50% if you find ways to save weight on the structure.
   
  6. I don't see any way to run a car, even a small one like mine, purely on 
these particular (now used) F cells.  Even if I had a few thousand of them.  At 
a 2C max discharge, I'd need 3360 of these cells and 480 individual small 
chargers.  That is "nearly impossible" to hook up and probably would not fit in 
the car.  Better cells would be a different story.
   
  7. Hooking up the cells is also a dilema.  You need a DC parallel spot welder 
(which I am very familiar with), but they are expensive.  I ended up using very 
high grade battery holders that can handle only about 25 A.  That is another 
reason why I can't go over 2C discharge.
   
  So, I'm not sure where all this is going.  I need to run some more 
experiments with charging at different rates and peak voltages.  I am open to 
suggestions.
   
  Overall, I have to say that this is not the type of project an inexperienced 
person of beginner to the EV world should try.  There is a serious danger if 
these cells are used improperly.  Because I have a lot of experience making 
these packs, I am comfortable with the tests that I am running, but I would not 
recommend it to the average EV enthusiest.  I am open to comments and 
suggestions.

I for one love what you guys are doing and read the stories avidly and
forward these off to my family and friends, KEEP IT UP!!!  I just
don't usually post as I have nothing to contribute and put my foot in
my mouth messing up the facts ;(  I can't wait to eventually get out
to the West Coast for an EVent but have been very content to make the
East Coast EVents for now.  It's been great to meet everyone who's
made it out to PofDC the last two years, Joliet last year and the past
BBB.

Hello Jim,

Thanks for your comments.

I should be getting my GE motor in about two weeks.  They had it for about 
two years.  The problem was that the same guy that built it is not around 
any more and took them about a year to get the winding data from the 
Electric Fuel Propulsion company that once was base in Troy, Mich.

They only built six of these motors using a standard traction motor frame 
which was wound in a certain way.  The weak spot in one of the windings was 
cause by the rear end bell pressing against the wire which flatten it some, 
and after thirty years it finally open.

When this winding open, it cut this coil in half and look like shot gun 
blast went out which turn up all the other windings.

The rear bell housing was custom made to fit any bell housing of a 
transmission and they made it too deep, which press against one of the field 
windings.

They said they made tighter end windings so there is now about 1/8 inch 
clearance to a mica insulator that is attach to the inside of the rear bell 
housing.

I plan to take a set of pictures, showing the motor with this custom bell 
housing.  The motor mounting unit. How a blower motor is attach to this 
motor and two types of motor adapter couplers.

It will also show three types of transmission coupling systems which use a 
standard transmission or a 0 rpm lock up automatic and the equipment to do 
this in exploded view.

I'd hesitate with newer cars, but older ones tended to be designed with a 
bit of margin when it comes to load.  In most cases, the main concern with 
exceeding GVWR is brakes and handling.  These can often be trimmed up with 
custom or factory high performance parts.

I'm a fairly cautious person, but I personally know Escort wagons that do 
fine for tens of thousands of miles with half a ton of lead onboard.  Honda 
Civics, too.  They need stiffer rear springs, however, and you want the best 
brakes you can get.

I read once that the Renault 10s converted by Bob Aronson tended to 
literally come apart at the seams after 20 years or so of use.  But the car 
was very light and small, and he was dropping in lead weighing something in 
the >>one ton<< range.

Prius battery packs work very well for Priuses (Prii?).  However, their 
energy storage capacity is too small for a real EV.  They are made of cells 
the size of those used in flashlights!

A few people have experimented with paralleling several packs to increase 
capacity.  This is fraught with problems, however, particularly in charging.

Not to worry.  Many of us have melted terminals.
You can get another melted on for about $5-10 where
you purchased the battery.
The bigger question is why.  In my case, I climbed a
hill and tossed it into 3rd.  Big mistake.  Should
keep RPMs high with an EV, and battery amps _down_.
I simply bypassed the bad battery to go home.
The biggest part is probably inhaling all of that
melted plastic around the terminal! 
   After the new post is on, the plastic that melted
around the edges will allow acid vapor to come up and
corrode the terminals a little faster, so be sure and
use plenty of vaseline to seal it, and inspect it
often; use baking soda to remove the corrosion that
ensues.
The only other likely culprit is that you didn't make
sure the terminals were tight, and they had lead
"creep"; that is, over time, the lead deforms.  But in
7 mos., I'd doubt that.
Hope that helps and that you're on the road soon.
peace,

I don't know if any type of Li-Ion cell will withstand a prolonged dead short without damage. They have such a large amount of stored energy for their mass that when you dump all the energy into the cell itself during a short, the cell gets way too hot. This is a direct consequence of the high specific energy of Li-Ion. Not much you can do about it.

If you use a second set of diodes for charging, then you have completely
isolated any problems in a shorted cell while you can still charge and
discharge through all strings.
The voltage difference between the charge and discharge points will tell you
if there is a string not playing nice, normally it should only be the
voltage drop of two diodes.
How much current does each string need to deliver?

Tesla Motors' Roadster has about 60 parallel strings if I take the nr of
cells (6000+) and divide that by the voltage that I expect they are running
(300+) so they probably have some 100 cells in series, though their BMS may
break it down in smaller sections.
Each string in the Roadster is probably capable of delivering around 10A.
(6000 x 3.4V x 10A = 200kW)

Subject: ARGGG, destroying expensive lifepo4 cells. :( Need a "button" fuse.

Hi all,

Does anyone know if there exists a "button" fuse, where each contact of the
fuse is opposite of each other? Sort of like a coin lithium cell? The reason
why I'm searching for them is to protect cells in parallel from a failed
cell.

So, I'm trying to see if lithium iron phosphate 18650 cells can be used in
parallel/series in a 4S5P pack.

I bought 21 cells from www.batteryspace.com, and fiddled with them. I
accidentally shorted two of them! They got hot and dumped full power for
about 10 seconds or so. Drats, one was ruined (fails in a shorted state),
the other, seemed ruined (very very low voltage, like .3 volts) but after a
day, it charged up fine. Cool, I thought. So at least I still have 20 "good"
cells. I mark the ruined but revived cell.

I wired up a 4S5P pack using lifepo4 cells from www.batteryspace.com. I put
it through a charge/discharge cycle on my charger, it works fine! Then I
charge it again, and notice it comes up as 9V only. ACK! So it turns out
that the "ruined but revived cell" failed short again, and it took out the
other 4 cells in parallel with it! Now I'm left with 15 cells, and 6 ruined
cells, at almost $7 apiece, this experiment is getting expensive. :(

I'm thinking it might be wise to wire up a fuse with each cell, but the
logistics of wiring that up seems daunting. Is there any fuse that is like a
button cell, that I can just put on the "+" end of each 18650? I've googled
and all I've found were SMT fuses, which are too small. I've thought of
maybe using glass fuses, but the glass would probably crack inside the pack.

                                                    - Tony

Yes, the BugE sits higher. I sat in the prototype a few weeks ago and it is
about as tall as a Corvette.

Thanks Dan. I did not realize they were so low to the ground. I wonder if

Hey Rod, all

Chin up 'ol boy.  There's more intrest than meets the
eye.  I'd bet EVeryone here's felt like they were
typing to a wall at one time or another.  As someone
who plopped into a lions den smelling of meat I've
found myself a hub as you've all circled around for a
piece of the kill, LMAO!  Yeah EVeryone wants a piece
of Jim 8^o  You know you don't see many motor or batt
guys here LMAO!

Right now I'm ass deep in Lasless' motors trying to
address every issue I can so he doesn't destroy them
or himself when he hits them with 1500 battery HP and
4 Zilla's.  Now if that ain't intrest then I don't
know what'll cheer you up then 8^P  Mike Willmon's
putting together a racer and from what I hear he's
gunning for Wayland (I might have to see if I can help
him out on that 8^o)

It may not be the good old days (yet) but there are
more racers out there than when I started!  I missed
all those years, so I'm doing what I can to throw some
color onto the canvas.  If I don't do at least that
well then I give up 8^P 

I think James Sullivan post says a lot.  I bet many
love to read it, but don't want to be the 234th person
to say "Yeah to go" so to speak.  On the other hand it
is nice to get feedback so when you hear crickets
you're not thinking that EVeryone's muted you, LMAO.

As far as I'm concerned if you old timers fade from
view I loose 20 freaking years of experience!  So you
just better suck that shit up right now.  As someone
who's only fought the fight for 2 years and not 20 I
may be niave but I got passion to spare.  

To be honest I'd like to see the west coast do an auto
/ scoter cross.  Just somewhere people could drive /
race smaller stuff like gokarts or us having a little
mini-chopper showdown, 8^o  Oh Yeah I got my eye on
you!  I think more people would be involved if smaller
first time EV's can be brought and driven before
advancing to bigger and bad'er projects .  I fit in
that catagory.

Anyway I just had to say to all you guys, Keep
shouting, I'm hearing ya and enjoying all the reports
and stories (you know me I like a colorful list 8^)
Even for me though it can be hard to reply without
sounding like Waylands groupie bitch, ya know?

Anyway I may bitch and moan but FWIW you're still my
candy 8^)  BTW I missed out on Maniac Mazda so I don't
want to hear any whining!

Of course I could be another moron screaming in the
darkness but that's okay I kinda like it... and the
company's not half bad 8^)

Hope this helps
Cya

PS: Yeah the list is back!

Hey, I'm with james s... A lurker, but interested in what's going on. Please
don't think that there's a lack of interest just because we're unwilling to
clutter up the list with unqualified nattering. I for one will become more
active after I have learned more.

I could be wrong, but I believe these bills only raise the maximum speed the
vehicle can travel to 35mph, and leaves the maximum posted road at 35mph.

BTW, on my GEM that has the governor limit removed, I have on problem going
up fairly steep grade at 35mph.

I agree Roger,

NEV's are not safe mingling in faster traffic.

They are niche vehicles, work fine in places like Vancouver where traffic
crawls, and collisions are more likely to be low speed.

Most existing NEVS have little headroom in power.  Some you can add blowers
and be OK. But if dealers just start cranking them up willy-nilly with no
cooling upgrade there will be burnt motors and controllers littering the
downslopes of hills across the US.

And as Bob says, with some NEVs you can crank it to 35mph, but hit a hill
and they'll bog to 15 or less instantly. Wham! Their controllers haven't got
the current or the tiny pack is sagging.

Manufacturers may balk at the extra cost of upgrading across the board. But
if they do "higher speed models" just for the elevated states, there'll be
more confusion with cross-border re-sales.

That will undoubtedly vary from one situation and individual to another.

My experience using a NEV on 50kph (~30mph) and 60kph (~40mph) roads was
that I was seldom, if ever, unable to match the flow of traffic despite
the NEV's lower speed limit.  I used the car to commute to/from work on
surface streets, so reasonable traffic volume and plenty of lights.
Often people don't appreciate just how much slower than the posted
limits they really travel even if they do zip up to the limit (or above)
between lights, etc.

It really has nothing to do with what the vehicles are capable of
attaining; the low maximum speed limit applied to NEVs is a *safety*
issue.  NEVs are *governed* to their low max speed; it isn't that they
are inherently incapable of exceeding these speeds.

Remember that the NEV vehicle class was created to allow these
'car-like' vehicles to be operated on public roads without having to
undergo crash testing.  The low speed limit, and  restricting their use
to roads with lower speed limits was intended to limit the amount of
carnage that would result when a NEV collides with another vehicle or
stationary object.

Personally, I think is irresponsible to legislate the ability for these
vehicles to be operated at higher speeds or on higher speed roadways
(where they can and will be struck by 'normal' vehicles travelling at
higher speeds) without first evaluating the ability of the vehicles to
protect the occupants in this environment and perhaps legislating in
additional safety requirements or performance standards to ensure an
adequate level of protection is provided.

NEVs aren't required to be crash tested, but the Canadian government got
samples of a few and did just this, then presented the videos of the
tests.  One very popular NEV when subjected to a frontal crash (at
either the standard 30mph or its 25mph max, I don't recall which),
disintegrated completely; there was no crush zone behaviour, the impact
would have been fatal for occupants.  Another NEV subjected to the same
test did exhibit progressive crush zone behaviour, however the seats
ripped free of their mountings, again turning this into a fatal event.

A significant difference between these and a moped-like vehicle that can
exceed 25mph is that NEVs are designed to appear car-like, and consumers
may not appreciate the difference in safety standards applied to NEVs.
It is not at all unlikely for a consumer to strap an infant or child
seat into a NEV...

I think that more sensible legislation would be to continue to restrict
NEVs to roads with speed limits of 60kph/40mph maximum, but allow the
NEVs to travel at speeds up to 50kph/30mph instead of the present 25mph.
And, if the legislation doesn't presently allow for it, provide the
ability for NEVs to cross roads with posted speed limits in excess of
60kph/40mph.  NEVs will never work for everyone, but they don't have to.

Cheers,

Roger.
