I kind of suspect that a hybrid DC/AC combination might work pretty well...

I have some toshebia laptop chargers that are 15V out,
and limited to about 2 amps.  I can use one across a
6V battery, and the charger will be fine (will limit
the current by dropping the voltage to what is
necessary).  I'm not saying yours will do this, but
who knows...

I'd go for the 12V light bulb in series to protect the
charger.  As long as your 4x cells don't drop below
(19V-12V=7V), the light bulb will never see more than
12V, although I'm sure it can handle a bit more.  The
only down side I can see is that it will slow down
your charging a bit.  Not that you are looking for
fast charging with this setup.  This is assuming that
the BMS can handle the extra voltage/current; depends
on the BMS.  I guess the safest thing to do is throw
in a couple of >3 amp diodes as well.

Another thing that I have done for charging small
NiCds is take two LM317 adjustable voltage regulators.
 I set the first one up as an adjustable current
source (to limit the max current) and then the second
one up as an adjustable voltage regulator (to limit
the max voltage).  You have to pay attention to how
much power they will dissipate if you are planning on
using them above a 1/2 amp or so.  But you can cheaply
and easily build a setup like this with your small
laptop charger to conservatively top off your cells. 
The details are in the various LM317 app notes.  There
are even TO-3 versions that can handle several amps (5
I believe).  Most importantly though is to pay
attention to the max power they can be asked to
dissipate.

Ususally these powersupplies get quite hot if used this way. They 
commonly have overcurrent protection so you will not harm the 
powersupply easily. Lifetime will be less due the heat anyway.

You could get better result if you just buy 4 pcs of 5V chargers and set 
them to 4,2V. Those powersupplies should be isolated. So no prob then.

If you're counting on hysteresis you perhaps would be better off by 
setting the end of charge voltage a bit lower. Say 4V (For LCP) would be 
excellent already.

With LPFs you can stop at 4,8V.

This way you're extending the lifetime of the cells.

SSH is used to remotely update the charging algorithms. Every cell has 
their own charging criteria.

Also the logged cell behaviour is being updated to our serves over web. 
We have background in telecom server systems where these kind of Linux 
sets are widely used. It's just exported from that world to manage Lions 
on EV. Down time usually is less than few minutes annually and 
production volumes for the main components are already in millions. => 
cost effective.

This CCS system allows us to take an action against bad cells before 
they even become a problem. So far the (almost) real time remote 
diagnostics have solved many issues on the road. Ususally in few minutes 
after call from a customer. We are checking on each vehicle weekly to 
see if there is anything ou SW has not noticed.

Since there are always some bugs on the beta versions (and surely in 
production versions too) new problems have found every now and then. But 
most of the fixes are transparent to user.

Since there is Chinese verision of the GUI some of the users have had 
problems to change it back to Finnish. Now the GUI has new face again 
and it's more usable.

Few times the charger outlet has had a blown fuse and user has summoned 
the superuser to help. Etc. drastic issues. :)

We are doing solutions on EVs all the time. But I'm still waiting to get 
  some kind of generic systems out there. Since it has taken years and 
no vehicle OEMs have real interest on EVs... We need more drastic actionos.

Actually in new vehicles there is already the Linux CPU hidden in the 
dash. That can be used too. Thou.. requires a bit of cracking... warm 
Coke and cold pizza...

Hello Josh & Jenifer,
Yes it is needed if you have over a 136 volt system. The maximum voltage
without the transformer is listed at 170 volts. That would give you only
14.166 volts per battery in a 144 volt system. If you use the transformer
you will have a lower charging current as well.

We have problems here!

First off, your power supply being 2.2v over the max charging voltage is a 
problem because the power supply probably will NOT lower its voltage to stay 
within the limit.  The current will be too high and either the power supply 
will shut down, let out the magic smoke, or deliver an excessive current to the 
battery.

Well, for an LM317 the biggest you can get is 1.5A versions.  The dropout at 
1.5A can be as high as 2.5V, so that may further limit the current slightly.  
The batt starts as 12v when discharged, so the reg at 1.5A would have to 
dissipate 10.5W.  This is not impossible but requires a fairly substantial 
heatsink and skilled mounting to maintain a reasonable junction temp inside the 
reg.

How much current can your BMS shunt?  At 4.2V/cell, 2.4 amps getting bypassed 
through the shunt means 10W through the shunt!  This could be a problem, 
although it depends on the BMS design.  Really what needs to be happening here 
is once a shunt activates the power supply needs to limit its current 
significantly, enough to allow all cells to reach full charge without exceeding 
the bypass capability of the BMS.  Even with the BMS, a lithium batt shouldn't 
be left on the charger indefinitely because even being held at 4.2V they do 
still absorb a small amount of overcharge.

After studying the Voltage vs time chart provided by Trojan for my AGM31
batteries this is what it works out to in amp hours. This battery is rated
at 110ah at the 20 hour rate.
50 amp draw  79ah
100 amp draw 55ah
150 amp draw 45ah
200 amp draw 40ah
So you can see that because of the Puerket effect total ah available drops
from stated 110ah to as little as 40ah when pulling 200 amps. My car at
45mph is drawing 150amps so according to the chart they sent me I get less
them half my stated batter capacity. Which seems to hold true because I can
drive 20 ? 25 miles before I have to charge. That?s at 73 degrees when the
temp drops into the 30 I get about half of that.

Good for you!  

For years I've been convinced (and I'm sure I'm not the only one) that 
battery leasing is the way to go.  I think that the cost of the battery is 
such that successful factory EVs are best implemented this way.  

However, although I'm not located there, and info has been a bit sketchy, my 
impression is that previous European experiments with a battery leasing 
scheme didn't fare so well.  From what I can tell, this may have been in 
part because they had only one supplier to work with, and that supplier 
didn't support the batteries well when longevity problems developed.

With lithium, it appears that there's potential for a larger field of 
suppliers.  (Granted, most are in China, a source of concern for some 
people, but I think some potential (if not current) lithium battery 
suppliers are in  
Taiwan and a few in Japan - yes?  no?)  IMO, competition is key to success 
of a battery leasing scheme.  We must have enough hardware suppliers to spur 
competition for the leasing companies' business with improved performance 
and lower price.

Your communication system is another sorely needed component.  While the 
privacy issues it raises make me a little uneasy, I also realize that 
continuously monitoring battery performance is just about the only way that 
the leasing operations are going to assure reliability (at least until 
competition develops on reliabilty).

Nice truck, Damon!

I like that now I can now point people to your Album entry and say, 
"see: another EV driven by an old forklift pump motor."

(That said, ALL other comparisons to my ride end there!)

are added fields you can't see that have to be updated to make your page 
work properly.  Basically, please don't link to your page until it is in 
the index.

Links should look like: http://evalbum.com/1524

BTW, 1397 entries!

Thanks,

Yes, but this is my second EV.  I have already done my "shoestring budget and 
just do whatever you need to" to get it running EV build with my motorcycle.  
So that would probably be better to compare to yours.  What!? You didn't know 
building that first one only makes it worse not better.  
I love my EV motorcycle and have put over 3000 electric miles on it, mostly at 
less than 10 miles a trip, but I would think about adding a lithium pack or 
upgrading the controller and deep down I knew that I didn't want to spend 
anymore money on it.  It is what it is and continues to serve its purpose well. 
 I wanted to start over with something brand new and build something really 
cool that I could keep for a long time and continue to improve over the years.  
That's what this truck is about for me.  In fact I was looking at personalized 
license plates and I am strongly considering MYHOBBY, which is available in 
Washington right now.  Of course, so is LECTRUK which I know used to be and I 
think still is on John Wayland's (in Oregon) baby blue 1968 Datsun truck which 
is now owned by Marko and likely will spend time side by side with mine at 
local EVents.  That might be kind of cool, two old Datsun trucks sitting next 
to each other with the same plates from different states.  !
  I can also get VOLTS which is Blue Meanies (Oregon) plates and where I got a 
lot of my inspiration for this truck...  Decisions, decisions...

Since I mentioned Blue Meanie, I should jot down how my truck came to be so 
close in color as it is kind of a funny coincidence.  I am actually a little 
embarrassed to be such a copycat and also anxious to see the two side by side 
to see how close I ended up in color.  I think mine has got a bit of a darker 
slate base and not quite as much purple or pearl, but I am a bit color blind so 
it's hard for me to know for sure.  Anyway when I say that Blue Meanie was my 
inspiration I mean it in many ways.
First, there is the fact that Blue Meanie hasn't always been the Blue Meanie it 
is today.  It's fun to listen to John tell stories about his first experiences 
with it.  I believe he started running at 48 volts with 4 normal car batteries, 
and an aircraft starting motor, but I don't remember the details for sure.  The 
relevant fact to me though is that you do not have to start out building your 
dream EV right away - you just need to start with what you can.  Also if you 
start with something that you really like and get it in great shape you can 
prolong the adventure by continuing to improve and upgrade it over the years 
and make it fit what you need it for at the time.  I remember the first time I 
saw Blue Meanie it was when John was working in an office building not far from 
my house, probably about a 15 mile commute for him.  He was able to pull it 
inside while he worked and had it charging using his on board bad boy charger.  
Thirteen Optimas and a bad boy charger gave him!
  everything he needed to use it day in and day out.  Another thing that Blue 
Meanie taught me is that if you make something look really nice and pay 
attention to the details it almost doesn't matter what it started out as.  It 
can be transformed into something really cool.  I dare you to find even a 
single person who has ridden in Blue Meanie who didn't for at least a second 
wish it was their own.  Think about that for a second.  That thing is an early 
70's econobox and John transformed it into something so cool that everybody 
wants it.  Finally, I learned that sometimes you just have to be patient and 
persistant enough and insist on getting things right.  John is very detail 
oriented by nature while I am not, so this has been a challenge for me.  One 
trick that worked for me though is to get other people involved who are detail 
oriented and have it become their project too.  My body guy Tom was great and 
did a fabulous job making the truck look awesome.

Now, about the color.  I agonized over what color to paint this truck.  Tom 
suggested keeping it something light because that hides imperfections well.  My 
wife likes white cars so that was a strong contender.  I googled for pictures 
of the same or similar style trucks to see how different colors looked.  I was 
starting to get worried because it seemed like every color I saw made the truck 
look ugly and even started wondering if I really liked this body style or not.  
Finally one day I saw a red one parked in a parking lot with some nice chrome 
rims and thought it looked pretty nice.  Since I already have a red Insight, 
that I have always loved the color of, I thought maybe I would just paint it to 
match the Insight.  Then one day when I was going over different color options 
with Tom, he had a sudden inspiration.  He had some nice paint that he had 
bought for a project but never used.   He got it out and it was this beautiful 
dark blue with a tinge of purple and pearl.  I t!
 ook a sample home to the family and we all knew that we had finally found the 
right color.  There were only two problems.  First since it was such a dark 
color Tom was going to have some meticulous body work to make it look nice.  
Second it looked an awful lot like the color of Blue Meanie.   So there I went 
from agonizing over what color to paint it with no clear winner to Tom just 
happening to have the perfect paint sitting unused on his shelf...  The day I 
walked into the spray booth after he painted the cab and while it was still 
shining under the bright lights I was blown away.  The truck was absolutely 
gorgeous, everything I had hoped for.  The pictures I took and posted on the EV 
album on a wet overcast day barely begin to do it justice.  You really need to 
see it sparkle in the sunlight to get the full effect.

We are doing solutions on EVs all the time. But I'm still waiting to get 
  some kind of generic systems out there. Since it has taken years and 
no vehicle OEMs have real interest on EVs... We need more drastic actionos.

This is exactly what I did for charging my Thundersky cells. I have a 
Megapower modular power supply that uses Vicor clone modules. I 
installed four 5v 30amp modules, and trimmed each one to 4.2v. These 
four modules were used to charge the 4 TS-LP90 cells in my pack.

Customer Ray M. asked why there wasn't a Q & A section on the Russco
Website last December.  So, webmaster Chuck Hursch has just added a Q & A
link on the Russco Website that should answer your most asked questions. 
The Q & A section still has more questions to answer, and will continue to
grow.

New models of the Russco chargers were introduced on January 1, 2008. 
Russco chargers now cover 72-156 volt applications, use an improved Square
D GFCI circuit breaker and are available with more options.
