Rod, I will try to make bracket racing clearer. In bracket racing you submit
an ET (elapsed time) you think your car will go in the quarter mile. This is
your "dial in time". You have to go as close to that time as possible
without "breaking out" of the time you chose. When two cars race, the one
that gets closest to their "dial in time" without "breaking out" is the
winner. The time that it takes you from when the light turns green until the
time your front wheels break the starting beam of light that triggers the
timer is called your reaction time. As I recall, correct me here if I'm
wrong Dennis, a "perfect light" is a .005 of a second. Dennis was running
.007s most of the day. That is within .002 seconds of a perfect light Watch
that on your chronograph sometimes. To really put this into a perspective
you might enjoy, consider just how much quicker Dennis's time is compared to
the blink of an eye. The average human blinks at the speed of 300 to 400
milliseconds. So Dennis's reaction time is consistently 150 times quicker
than the blink of an eye. This points to an old adage, practice makes
perfect. Dennis even carries a practice tree type electronic device when not
at he track in order to hone his skills. this is called dedication. I hope
this helps you to understand bracket racing better.

I think this is good news?
I'll admit Dennis that I don't have a clue how
bracket racing works. I'm guessing you jumped the gun
on round 4? Any more details on the final results?
I really like to hear results of the CE, but sometimes
the

I wish you the best of luck in future races, you are a
true
inspiration in the EV racing field and a pioneer in

Keep up the good work!!!

Don,
Small correction to the Electric mode info you gave, as
there is a lot of misinformation spread around by people
who want *full* Hybrids to fail or reduce the perceived
avantage over a souped up starter motor that some dare
to call Hybrid:
not 15 but 42 MPH is the redline of the electric motor on
my Prius, when the ICE needs to be started to reduce the
speed of the electric motor (the torque converter is
attached to the 2 electric motors and engine in a way that
causes this limit, but the power required to sustain
42 MPH also makes it logical to kick the ICE on at
this point. See http://john1701a.com/ for a bundle of
Prius information and photos by an enthusiast user.
Also explains how the torque converter is attached and
how it gives continuous variable transmission, so the
engine can be revved up for launch, revved down for coast
and even stopped without changing the speed of the car.
I manage to drive more than 2 miles on local roads (30 MPH)
before the engine comes on, even though the official spec
is only up to 1 mile. I would love to have the famous "EV"
button that can be installed in 2004 and later Prius, but
which is not available on the older models (as I have).

Yes, I'm aware of the Prius (non-"plug in") capabilities. The ICE kicks in
once the Prius reaches 15 mph and the Prius will only go a very, very short
distance on batteries alone I'm hoping that this Mariner might go a bit
further on batteries than the non plug in hybrids. Just curious what "full"

Mike,
If this Force uses Solectria charger (which is BRUSA NLG412 copy),
then most likely the temp sensors are plain 33k NTC thermistors.
"Most likely" because this is what NLG5 currently uses and I don't
see good reasons for BRUSA change that, but I don't know this for fact.
Try Digikey BC2308-ND: his is the part that comes with NLG5.
If you connected it right way, the charger should at least work.
Once it does, you can tweak compensation later. If the voltage
on charge is too high (provided 25'C setting is correct), lower
this resistor, which will tell the charger the battery is hotter
so it will lower its output, and vice versa.

Hi folks,
Please bear with me here, electronics is not my area so I probably sound
about half a bubble off center.
I have an old Solectria BC1000 charger, setup for a 156 Volt Force that
I would like to use on my Civic conversion as an opportunity charger. I
tested it in my Force before I sold it, so it does work. The problem
is, it won't work without a temp sensor and I have no info on the
sensor. I have emailed Solectria but received no response. The new
owner of my Force did probe the connector at the charger and was able to
determine the resistance between the three wires. The batteries were
probably somewhere around 68 degrees F and he found from the black wire
to the green was 65.8 K Ohm, from black to red was 53.1 M Ohm, and from
green to red 5.41 M Ohm. Is it possible to identify a compatible sensor
based on this info? If not a sensor, can I make up a jumper to fool it
into working? The point is to just get the think working well enough to
give me a lightweight 120 VAC charger on the Civic that won't trip a
breaker and won't fry the batteries. Currently I am using a home built
setup based on the guts of a "Fair Radio" charger with a 24 Volt
transformer added and a 12 hour fan timer for control. The whole think
is probably 80 pounds and is not efficient nor does it bring the pack to
full charge.
Another chapter member has a similar charger, from an older 144 Volt
Force. He would like to try to use it as an opportunity charger on his
120 Volt pickup conversion. If the temp sensor issue can be solved, is
it possible to reduce the output voltage from 144 to 120 by using a
series of diodes in the output?

Hello John,
Its best to put the PFC in a separated insulated compartment at the rear of the
battery box. The PFC should be under fan positive pressure and the battery box
is under another exhaust fan negative pressure.
With these enclosures next to each other, you have a short conduit chase
nipples for the battery cable to run to. Seal the cables in the chase with
electrical duct putty or black 3-M strip caulk.
The battery charger is place in a enclosure that is insulated from the frame of
the vehicle. Only the battery charger is grounded. You then will not get a
full charging voltage from any one battery terminal to the frame of the car.
With the battery charger being at the rear of the pickup, it is easy to reach
and adjust and monitor DC and AC amp and volt meters. The AC plug and
connector I used is a heavy duty 30 amp 250/125 VAC 4-pole, 4 wire that is in a
all nylon water proof cover with a overlapping lip. This is made by Daniel
Woodhead and I been charging 40 to 50 amps on it since 1985.
The receptacle is under the existing gas filler door. The receptacle is
recessed in a separated cast aluminum water proof box, that also have a weather
tight hinge cover on it. When I lift up the gas filler door, it also lift the
receptacle cover to. The water tight receptacle box is made by Bell Co which I
used a 2 gang size.
It is only a short distance for a power cable that is connected to the back of
the receptacle box with a weather tite cable box connector. A conduit hole is
cut in the bottom of the bed of the truck. The charger box is bolt down and
place over this hole and than hole saw threw the bottom of the charger box.
A conduit nipple go's up threw from the bottom of the pickup bed to just inside
the charger box, where you install standard conduit locknuts and bushings on
both sides of the conduit nipple. When the cable goes threw this conduit, seal
it with electrical duct putty or you can connect another cable box connector on
the bottom of this nipple using straight or 90 degree type.
I used a 90 degree cable box connector connected to the conduit nipple, because
I did not want a large loop. The cable went straight to the rear of the
receptacle enclosurer.
The battery and charger enclosures being in a bed of a pickup, there is enough
room around the sides and bottom to place high density Dow Corning Blue foam.
I have 2 inches on the side and 1 inch at the bottom. The foam is glue onto
the fiberglass boxes with foam glue. A marine nylon carpet is clue to this
foam, so as to keep the foam from damage and its makes it easy to slide the
containers in the bed. The bed of the pickup is also insulated with 1/2 foam at
the bottom and 2 inches on the side, and also cover with a marine rug.
This gives me over 20 R-Factor which calculates to 1/20 = 0.05 u factor.
The u factor is multiply to the total square foot of the insulated surfaces.
Lets say you have 50 sq.ft. of enclosure surfaces. The outside temperature is
30 below and you want to maintain at least 70 degrees inside the enclosures
which would be 100 degrees difference. Then:
Btur's = sq.ft. x u-factor x temperature difference
Btur's = 50 x 0.05 x 100
Btur's = 250
Therefore with 2 inches of foam insulation, it only loses 250 btu's per hour at
30 below.
3412 btu's is equal to 1000 watts.
I actually have 4 inches of foam on the sides. If the inside of enclosures is
80 degrees, it will only lose 15 degrees or down to 65 degrees after setting
all day at 30 below. If there is any sun light, it will push the temperature
above the battery compartments above 80 degrees if I park the EV with the glass
hatch facing the sun.
If you have a enclosed battery box, one trick I learn, is to fill the bottom of
the box with about 1/2 inch thick layer of baking soda which the batteries set
on. My batteries are four years old and they are very clean. The white epoxy
surfaces are still mirror clean. Before I did this, the surfaces would get a
yellow ting from battery fumes. Now I do not get any. The batteries are
completely dry. There is no current tracking from any one battery to any other
surfaces.

I've been wondering about charger placement as well for my 86 Nissan
King Cab conversion.
I seems there are 3 general placement locations, In the truck bed with
the batteries, Engine Compartment, and passenger compartment. My
charger is a PFC-30 and I now live in Western Mass where it gets fairly
cold in the winter. Does this device need regular fiddling that would
make a passenger compartment installation beneficial?
If I make my AC to vehicle connection point in the front of the truck,
are there drawbacks to running an AC line back to the charger in the
bed?

Actually, this is the much older charger that Solectria apparently
made themselves, it even says Solectria on the circuit board
itself. I have no idea if it would have the same sensor as the
NGL412, I thought that used a two lead sensor not three leads.. It
is only 7 Amps output, the Forces that came with them used two. As I
just intend it as an opportunity charger the low output is not an
issue, but it would still be an improvement on my opportunity current
charger. I am going to give the 100K pot solution suggested by Roger
a try, I figure adjusting a trim pot might actually allow me to kind
of get it more in line with the requirements of my AGMs rather than
the gells it was programmed for.

It is an EV, but it doesn't carry people. Of course,
I am talking about iRobot's Roomba Discovery.
We took the plunge and ordered a refurb one for only
$135. My main interest was to look at how it finds
its home base to recharge after cleaning (or when its
battery is weak) and how the contacts maintain a good
connection. It is well worth $135. Cleaning should
be left done by automated machines like the washer,
dryer, dish washer, and now Roomba.
Anyhow, the system is surprisingly simple. Two bright
IR emitters that emit different codes are placed at a
slight angle at the home base. So, if you move too
far to either left or right, you will receive the
corresponding IR signal to correct your heading. The
closer you get to the home base, the smaller the error
distance.
I could imagine a system like this for EV charging
stations. A small robot could be dropped from the
under carriage and it looks for the plug to plug in.
May be I am wishing too much.

Well, my wife has hit the 40k mile mark on the original RE92 tires on
our Prius. I measured the all the treads on each tire and found that
the smallest is down to 0.97 inch (minimum is 3/32.) Honestly, these
tires have sucked on wet roads since they where down to 1/8th inch.
They may be legal, but they have done their duty and I intend to
replace them some day next week. What is recommended? The stock size in
175/65R14 (902 revs per mile.) Wet road traction is a concern in
western WA (seeing as we just had 30 rainy days in a row!) I'd like to
not significantly damage the fuel mileage either.

That's the term they use for the Escape Hybrid. The latter is equivalent to
a first generation Prius, so it's not a plug-hybrid. All its energy comes
from gasoline. The term "full hybrid" just means that the engine doesn't
have to be running 100% of the time that it's under way, unlike the Honda
"hybrid" cars.

I'm pretty sure the BC-1000 was a Solectria design, not a Brusa charger, but
I might be wrong.
I have one of them sitting on the shelf in my garage, not really doing
anything. I'm too tired to go look at it now, but I don't recall it having a
temp sensor of any kind.

Mine came with only one. It is indeed a feeble charger.

This is getting OT. There are plenty of opinions on
the web. We had it for 2 weeks now. Although it
might not clean as well as the big ones on the first
pass, it makes multiple passes all by itself and it
goes into and under everywhere it could go on its own.
And, we don't have time to vaccum everyday, but the
machine could.
It is similar to asking how long it takes to recharge
an EV. Well, most of the time, I just don't care. It
is not my time. I just plug it in and it is full the
next morning. For Roomba, I just let it clean and
when it is done, it is clean, and it is back at the
home base charging.
I would not recommend it if you have a lot of pet hair
or long carpet. It might not last. It is perfect for
short carpet and hard floor. It would actually run
for 2 hours on a hard surface.

Hi Folks,
I know everyone has been waiting for the results and information about the
Battery Beach Burnout event this weekend (especially Jim Husted!). Sorry for
the delay but between being at the track until 2AM on Saturday and being
back out there at Noon to setup for the next days events and then doing it
all over again, everyone has been a little tired.
Before getting into the details of the events themselves, Id like to first
thank two groups people. First is the group of people that helped organize
the Battery Beach Burnout. Matt Graham and Lowell Simmons, the co-organizers
of the event, both were a major help in making the event what it was. Matts
support in the marketing of the event and planning and Lowells organizing
the Autocross and contacting the high school teams to attend was awesome.
Both of them worked very hard in making sure we had all the trophies, prizes
and were as prepared as we could be for the event. I could not have done it
without them. Id also like to thank several other people for the help they
offered during the event. Cliff Rassweiler worked with Lowell to setup up an
amazing autocross course for the area we were given, Bill Young for all the
help in selling shirts and raffle tickets, Jerry Dycus for being willing to
jump in any where he could help and also my wife Christina for all her help
keeping records, tracking times and putting up with me through all of this!
Any event is only successful if it has two things: people to attend the
event and people helping sponsor the event. Our sponsors have been great and
really enabled us to hold such a grand event right off the bat for our first
year. I would encourage everyone to check out the sponsors page on the
Battery Beach website (http://www.batterybeach.com/sponsors.html) and to
please support the companies that support EV racing and the EV events!
OK, the event itself. Friday afternoon, the generator was dropped off and
track officials got us all setup in our own area in the pits. It was really
nice having the 70kW of power available for everyone, charging was not a
problem! It was even nicer having the wonderful support that we received
from Moroso Motorsports Park, the track officials and management have been
absolutely fantastic about supporting the event and having the EVs out
there. At one point the staging lane coordinator told me he wished they were
all EVs he loved how quite they were. The weather was also great, t-shirt
weather, clear skies.
Friday night was the drag racing portion of the event. We had a great
turnout for the first year. We had lots of locals come out as well as
several teams from out of state to join in the fun. From out of state, there
was Ricky Lewis and his sons Tim and Chad from Northeastern High School in
NC and Shenandoah Valley Governors School showed up with two cars and an
entire team of students and parents. From here in sunny south Florida, we
had Matt Graham with that hot Nissan 240SX, Lowell Simmons from Miramar High
School, Steve Clunn with his new Mitsubishi truck conversion (Warp 11 and
all), Cliff Rassweiler with the Pro EV Electric Imp and Matt Graham and I
brought out a couple of electric bikes to run (including Orange Crush
sporting the motor from Jim Husted). After everyone got in and registered it
was off to the staging lanes
and then wait. The most frustrating part of the
whole event was the waiting. Moroso had the largest turnout of Sportsman
class cars that it has had in months. Despite the wait times in staging to
run, we got lots of good EV drag racing runs in throughout the night. We
raced till after 1AM. What a bunch of die-hard racers! Everyone was running
around tweaking cars and jumping back in the staging lanes for another run.
Some highlights of the night were Steve Clunn showing just how much power
that 11 motor has and how little traction that poor little truck had. His
truck may have been moving a little slower, but those tires had to be doing
150mph! This was Steves first time ever on a drag strip and I guess he was
a little unclear as to what to do when that green light came on. He adjusted
in a hurry and learned the ropes fast. He got back out there and was able to
post a top run of the night of 17 seconds. What a great sport Steve is and
will really be posting some better times when gets that rear end to handle
the power! Lowell Simmons was out in the Miramar High School Porsche 944
with a new setup at 192VDC. He put on quite the fireworks show during the
burnout with lots of arcing coming from those dual 8 ADC motors during the
burnout. Besides breaking in the new motors, Lowell was also trying to get
the new Z2K setup right in the car. The Porsches evening ended in
frustration when the driveline busted on the line. Still, a new HS/C record
was set at 19.88 seconds! Matt Graham had a frustrating night with the
Nissan 240SX. The car was not shifting from Series to Parallel at all and he
posted a best time of 14.46 at 95MPH with it only in series. (Matt will be
posting with all the details of the night in a separate post). Matt also ran
the SEVO/Hi-Torque Orange Crush bike. The bike is a 24V Super Pocket Bike
and was being run for the very first time. With no break in time for the
batteries and the night cooling off, Orange Crush powered by Mighty Tim
built by Jim Husted, posted a time of 14.04 seconds at 45MPH in the 1/8th.
We were less than .3 seconds from seeing a new MT/J record! Cliff Rassweiler
had some great runs after chasing out some gremlins of his own. For a car
setup for road racing and autocrossing, he sure showed his stuff on the drag
strip! This was the first time Cliff ever had the Pro EV Imp on a drag
strip. Cliffs best time for the night was 15.6 (OK
15.596) at 90MPH. We
also had some great High School action out there. Chad Lewis was driving the
Northeastern High School Volkswagen (96VDC) and the car ran solid all night.
Chad was very consistent in performance every run, posting times of 18.09 in
the 1/8th. Shenandoah Valley brought their two cars, a Datsun 240Z and
Porsche 911 (both 120VDC). They had some transmission issues with the 911
but still overcame the problems to make several good runs. The 240Z ran at
21 seconds in the ¼. Folks, watching these students drive these cars in the
drag race and autocross, I have to tell you, there is going to be some great
EV drivers in the very near future!
After a few hours of sleep (personally getting home at a little after 3AM),
we headed back out to the track for the Show and Shine starting at noon.
Moroso gave us plenty of space in the camping area to put all the EVs on
display. Besides all the cars we had the night before, Charles Whalen
brought out his two RAV4 EVs to show off and let people drive. Darin Pinard
brought out his new creation, a custom built high end electric Mountain Bike
what a blast! Jerry Dycus also had the shell for the Freedom EV on
Display for us to check out. Bob Rice made it down for the weekend to join
us. The Show and Shine was great. Everyone had a chance to relax and clean
up their cars and check out all the other EVs. During the Show and Shine,
there were two ballots passed out. The first was for all the spectators to
fill out and the other was only for the EVers to fill out. Two of the
awards for the Show and Shine were Viewers Choice and Show Choice. The
idea was to have the spectators vote for their favorite EV and the EV owners
to vote for the EV they liked. Matt Graham managed to sweep both of the
awards; however he was given a strong chasing for the lead on the Show
Choice by Shenandoahs 240Z. The final award given out for the Show and
Shine was the Best Design award. While there was no criteria for the
Viewers and Show Choice awards, the Best Design award was given out based
on the technology and engineering that went into the car based on its
function (performance, range, etc.) and did not take into account ascetics.
The winner was selected by committee. Originally, the committee was going to
be the three race organizers, it was agreed upon that since Matt and Lowell
both had cars in the show and shine, we should select two more people. Chip
Gribben and Jerry Dycus stepped in and worked with me to review the cars.
Ladies and Gents, this was not an easy task! There were some very impressive
EVs on display. Chip, Jerry and I agreed that several people deserved
recognition for the work in their cars, like Shenandoahs 240Z, Matt
Grahams 240SX and Miramars 944. However, the one car that stood just a
little higher in overall design was the Pro EV Imp. Its use of Lithium
Polymer batteries, twin AC drives and built-in on-board data acquisition
with a tablet PC for the dash display made it the winner. What an amazing
car to go through!
OK, its 4:30 PM on Saturday and the gates open to the track. We went in and
setup the autocross course. Cliff worked with Lowell to create an amazing
course. We had a smaller area than we had hoped, but Cliff and Lowell were
up to the challenge! In the short area they were given, they had two
straight-aways, slalom areas, tight turns and chicane all built in. I think
everyone agreed that the autocross was the best part of the weekend.
Everyone that wanted to got to run. The school teams got to run through with
several drivers per car. Cliff, like a fish in water, demonstrated his
prowess in the course (I guess it helps being a professional driver and
having a super hot car!) Charles Whalen brought his RAV4s out to display
them and give rides, but made it clear he wasnt going to be racing his
daily drivers. Yeah. After a little gentle nudging and assurance that the
autocross was not going to hurt the RAVs he ventured out to the course.
After his first run through the course, he got out of the RAV with a smile
that you couldnt take off with a Brillo pad! He was hooked! He then offered
up the RAVs for any others to run. Chip Gribben jumped in on that action
and took the RAV out to see what it could do. Another smile! Most of the
older EV crowd was put to shame by the high school teams of Shenandoah and
Northeastern. Shenandoahs 240Z drivers were hot! When these kids get older,
Cliff better be looking out for these guys on the road courses very
talented! Not wanting to end the fun with the autocross, we did have to
wind down. Not till we had a bit more fun though. Paul Little came out, but
was not able to bring out his electric Porsche 959 due to a mechanical
problem, but was driving his ICE Porsche. He ran the course in it.
Autocrossing is a practiced sport. The more you run the course, the faster
you run, making a little better time on each pass. Paul ran his ICE Porsche
through 9 times pushing and pushing to get faster, but after 9 laps he
posted a best time of 26.8 seconds for the course, beating most of the of
the other times. Well, all but one
after 9 laps, he still could not beat
Pro EVs time of 26.6 seconds after only 4 laps. We would love to have seen
how much faster Cliff could have gotten the Imp through after a few more
runs. What an impressive display of driving and performance by all.
Winding down from all the events we held the award ceremony and raffle
drawings. Lots of great prizes were given away. We had shirts from Megawatt
Motorworks, Alltrax, NetGain and Bad Fish Racing. NetGain also sent us
enough NetGain cups to give one to everyone there. We also gave out Gone
Postal DVDs, contactors, a 12V charger, multi-meter and commutator stones
from Hi-Torque electric. In a separate raffle, we gave away a brand new
AXE-4865 compliments of Alltrax. Alltrax was a huge supporter of the event.
Here is a summary of the Trophies that were passed out:
High voltage car (over 156VDC):
1st Matt Graham
2nd Cliff Rassweiler
3rd Steve Clunn
Low Voltage Car (under 156VDC):
1st Northeastern High School of North Carolina
High School Car:

Viewers Choice Matt Graham
Show Choice Matt Graham
Best Design Cliff Rassweiler / Pro EV
Autocross:
1st Cliff Rassweiler / Pro EV
2nd Harrison Mohn / Shenandoah 240Z
3rd Chad Lewis / Northeastern High School
Two other awards were given out. The first was the Battery Beach Burnout
Burnt Out award. This was given to the competitor who had the toughest
weekend with breaking and car failures. This years winner (well, sort of)
was Lowell Simmons and Miramar High School for the motor and driveline
problems they had. The second award was the Best Overall. This award was
given to the competitor who demonstrated great skill and performance in all
the events. It was a pleasure to give this years award to Cliff Rassweiler
and Pro EV. Each of these award certificates came with a custom made Palm
Tree sculpture made of copper. Jim Husted, aside from making amazing motors,
uses copper from burnt motors to create beautiful artwork. He sent us two
palm tree pieces a smaller one and a larger one. The smaller one was given
out with the Burnt Out award and the larger was given with the Best
Overall.
Again, I want to say thanks to everyone one who attended, supported and
raced at the event. It was a wonderful weekend and lots of great EV fun was
had. We look forward to next years event and look forward to it being even
bigger. We will have the full results and photos posted to the website by
mid-week, so please keep checking the site.
Thanks,
Shawn M. Waggoner
