If you had a heat exchanger, you could transfer the heat between the two
compartments without mixing the air.
You could have your heat transfer and still have safe air to breathe in case
of a battery fire or rupture.
A turbocharger intercooler style heat exchanger might be large enough.

The one UPS ( 12v 95lbs no name "best power") that stoped working has a vent
/top and I was able to pry off with a screw driver . The bat was dry and
there looked like there was wax covering the plates . I checked out one that
is in the car and it was day also . These are the used bat that I got the

I use nickel plates with stainless steel screws. I
was swamped by work, other projects, and a bad
charger. I have not been working on the Paseo for a
couple of months now. I hope I will get back to it
this weekend now that I got my PFC-20. :)

Interesting. What would one do to induce an Optima to catch fire? Simply
reversing it isn't enough. I'd guess you have to reverse it *and* force
a high current to flow through it?
A failed cell interconnect at high current might also do it.
Have you had any such failures? What conditions were necessary to induce
it?
The battery management system ought to make such failures less likely.

Well, it would be easy to slide a metal plate under the seat to block
the air intake and exhaust from the interior. Then the battery box would
be strictly vented outside the vehicle.

I revived some Concordes after putting two teaspoons of water in each cell.
They went from ~45 AHr to ~79 AHr after putting in the water. They were
rated at 105 AHr.

Dave Cloud has opened numerous Red Tops racing his electric hydroplane. You
might ask him about it.
The case was still intact on every one I saw that had opened. Nothing
melted. Nothing burned. Nothing blew up. I do not claim to have inspected
all of them. There may be exceptions.

Each charger has an 8-step charging algorithm that it uses if the
network is down or there are no orders from the central system. Or, the
central system can decide exactly what each charger is to do.
We're still playing with it to determine exactly what it does, and when.

We may go with either of these approaches (use liquid to transfer the
heat, or an air/air heat exchanger). The system we have is partially a
consequence of the way the prototype Tango is designed.

Hello All,
The time has come. After over two years of development work, I'm
finally ready to release the latest version of the Zilla controllers.
It's been terrorizing the streets around here for quite a while, I
figure it's time to go national.
Here's the PR Blitz:
http://CafeElectric.com/products/z2k/
Cafe Electric llc is pleased to announce the release of the new Z2K
motor controller package.
The Z2K is the latest and most powerful version of Cafe Electric's
line of electric vehicle controllers. Employing the latest high power
semiconductors and unique packaging with careful attention to detail
in design, Cafe Electric has succeeded in producing the most powerful
electric car controller available on the market today. In addition,
it has all been done in a package about the size of a shoe box.
This design builds on ten years of refinement which started with the
quarter megawatt controllers. This Z2K revision continues Cafe
Electrics' tradition of building ever smaller, more efficient and
more powerful controllers. These controllers have been breaking
records and winning races since 1992.
In addition to higher power, this release brings with it a host of
new features. The Z2K, with it's Hairball interface, is the first
ultra high power controller built with safeties making it appropriate
for street use. It includes dual isolated microcontrollers, each with
continuous cross checking and override capability to shut off power
in case of a detected fault. This gives the Z2K a level of security
unknown in previously available DC controllers from any manufacturer.
Cafe Electrics' controllers (previously known as EVCL) have always
led the industry as the highest power and most configurable
controllers available. The new Z2K takes this several levels further
with a long list of features including: Arc-less main contactor
precharging and switching, individually adjustable voltage and
current limits for the motor and battery loops, arc-less control of
external contactors allowing safe series-parallel shifting of dual
motors as well as electric reverse, a motor stall detect system to
reduce lifted bars on motor commutators, two motor speed limiters for
overspeed protection of motors, and outputs for a dash mounted motor
fault indicator light as well as an independently adjustable low
battery voltage indicator. More adjustments and real time information
updates are available through the standard RS-232 interface. All
these adjustments give you the ability to get the most out of your
batteries and motors, without making any of them go up in smoke.
All units come standard configured for water cooling, though air
cooling is possible in light vehicle applications. Due to new higher
power components, full motor current is available at over 130 degrees
F internal temperature. This eliminates the need for exotic cooling
to reach full power in most environments.
At 2000 motor amps and 348 Volts nominal input this unit is capable
of peak power of over 600 Kilowatts. If you really want to go fast
without blowing things up, this is the ultimate controller to bring
you and your vehicle up to speed.
Since these units are hand made in the USA, lead times are usually
about two weeks.
Check out the Cafe Electric llc web page for more information.
Thanks for reading, we now return you to your normal non-commercial email...

I must say that is one sano "engine" bay in one very beautiful

Whatever it is, it would certainly turn my head out on the road

The really weird thing is that they have the exact same body as the
Yamaha "Vino" two stroke. The other thing I find amusing is that they
are made in China but come with Taiwanese tires. Who'd a thunk it!
Roderick Wilde
The EVT 168 and the MoRad look a lot alike. If not identical. Must be the
Taiwanese scooter laws. Lawrence Rhodes......

EVLN(FVEAA helps with Park Ridge EV conversion)

Teacher makes electrifying move
BY DARCY HENDRICKS STAFF WRITER
A maroon 1994 Ford Escort station wagon sits in a school
parking lot.
It looks just like your average Ford Escort wagon, but it?s
not!
Last summer, Timothy Moore of Hillside, an industrial
technology teacher at Park Ridge/Niles Elementary School
District 64, converted his ?94 station wagon into an
electric car.
Instead of a gasoline engine under the hood, the station
wagon has a motor, controller, batteries and battery
charger.
It?s not that I have something against gas cars,? Moore
said. ?It?s just that I wanted to learn more about
electricity and cars.?
Moore is a former electronics and electricity teacher at
Proviso West High School.
When he went to Park Ridge to teach two years ago, he said,
he met a student, Karl Karrasch, who was interested in
learning more about electronics.
Able to work with students on drafting, plastics and
woodworking during the school day, Moore said he told
Karrasch to round up a half-dozen students who may be
interested in participating in an after-school ?Team Leisure
Club? on electricity/electronics.
Karrasch, an eighth-grader, gathered the six students by the
next day.
That was 1 years ago. Today, the club meets at 3 p.m.
Mondays.
It was Karrasch and other students that gave Moore the idea
of building an electric vehicle.
Becoming a member of the Fox Valley Electric Auto
Association two years ago, Moore began researching various
vehicles, learning about the conversion and speaking with
individuals who owned electric cars.
It took some time to find a vehicle for the conversion,
Moore said. For instance, he said, the vehicle had to have a
manual transmission.
By April, Moore had purchased a 1994 Ford Escort station
wagon for $2,500.
Conversion began with the removal of the engine and its
related components, which Moore donated to Proviso West High
School.
A DC motor is the substitute for an engine, and an
electronic controller is installed to regulate motor speed.
A battery has a 6, 8 or 12-volt rating. Moore said he
prefers to use 6-volt batteries.
With the help of members from the Fox Valley Electric Auto
Association, the conversion took three months. Then another
month to tweak various problems, Moore said.
Before the Ford Escort station wagon, Moore owned a 1988
Grand Marquis. Ironically, that vehicle ?died? the day the
wagon was ready to be driven, Moore said.
I was hoping, though, that I would have some time to get
used to the station wagon before I drove it,? he said. ?But
it started up the first time I tried it.?
The electric car is charged during the night and the school
day. School District 64 installed an outside outlet in the
Lincoln Middle School parking lot for Moore to charge the
vehicle. The outlet can be an average household 110-volt
outlet.
The superintendent (Fred Schroeder), (Lincoln Middle School
Principal) James Blouch and Jim Wuerffel (director of
buildings and grounds) were all very helpful,? Moore said.
Though the cost of conversion can range from $8,000 to
$12,000, Moore said he is saving money now. Maintenance is
very low because the vehicle does not use oil, and there are
no spark plugs, Moore said.
There is a cost, however, to charge the vehicle, he said,
but it is minimal.
An average electric vehicle can travel up to 65 mph and has
a range of 40-50 miles before needing to be recharged.
Each day, Moore travels 26 miles round-trip from his home in
Hillside to Park Ridge. That?s not bad, he said, considering
the average daily commute is 25 miles.
It saves Moore from using his gasoline-powered minivan for
short trips, such as going to work.
While at Lincoln Middle School, Moore said, he does not
necessarily have to charge the battery. However, he said,
keeping the vehicle charged helps prolong the life of the
battery.
Moore met recently with the Electricity/Electronics Club
students. After they worked on various gadgets, the six
students and Moore headed out to the Ford Escort station
wagon.
Enthusiastically, students requested Moore drive the vehicle
around the parking lot. After unplugging the electrical cord
from the outlet where the vehicle charges, Moore hopped into
the car.
He slowly pulled away and made a circle in the parking lot.
Equipped with a radio but no heat, the vehicle barely made a
sound.
Karl Karrasch was one of the students in the parking lot
that afternoon.
I think it?s pretty cool,? he said of Moore?s electric
vehicle.
With 30 hours of college credits in electronics and
electricity, Moore said he is learning a lot from being a
member of the Fox Valley Electric Auto Association.
If money was available, Moore said he would definitely
convert another gas-powered vehicle to electric.
Not only does it help with the environment,? he said, ?but
I'm able to keep up with electronics this way.?

UCSB Staff To Acquire New Wheels
By Melanie Chase - Reporter
Wednesday, January 15, 2003
[Kiersten Yount, a senior psychology major, transports
equipment in a Neighborhood Electric Vehicle. UCSB expects
to acquire over 50 of the zero-emissions vehicles for campus
use.] Brent Slonecker / Daily Nexus
Kiersten Yount, a senior psychology major, transports
equipment in a Neighborhood Electric Vehicle. UCSB expects
to acquire over 50 of the zero-emissions vehicles for campus
use.
If you haven't already seen UCSB staff members dashing
around campus at 25 miles per hour in what look like small,
Space Age golf carts, be prepared - more are on the way.
The cars, known as Neighborhood Electric Vehicles, or NEVs,
are the latest in zero-emission transportation technology.
Recently donated by Ford and Chrysler, about a dozen of the
vehicles are now in the university's possession, and over 50
are expected to be acquired in total.
"They started arriving around October," Transportation and
Parking Services Director Tom Roberts said. "In late
December we started getting more."
The NEVs, which are recharged by being plugged into standard
110-volt outlets, will be distributed to various departments
so staff members may travel around campus more easily and
transport materials between buildings. Currently, most staff
members use regular cars and vans to move around campus,
which creates problems with parking and is less efficient
than using the miniature vehicles.
According to Roberts, Transportation and Parking Services
will cover half the cost of insurance, maintenance, and
parking for the NEVs, while the departments using them will
be required to contribute the remaining $55 per month. "The
electric vehicles may replace some staff cars," Roberts
said, citing the lower cost of leasing and running the
vehicles.
While Transportation and Parking Services will round up
requests for the electric cars from campus departments until
Jan. 16, some groups are already putting them to use.
Housing and Residential Services has acquired its own fleet,
and the Custodial Management and Instructional Resource
departments are reaping the benefits of UCSB's most recent
additions.
John Davis, Classroom Service manager at Instructional
Resources, said his department previously had to use a van
to take computers, sound equipment, data projectors, and
other technology to an average of 120 locations on campus
every day. Now the staff is using NEVs, which Davis said
"have better visibility, are easier to use and easier to
park."
Not only will the NEVs heighten efficiency on campus, they
will help UCSB reduce harmful pollution, as the
environmentally friendly machines release no tailpipe or
evaporative emissions.
"Zero emissions is better for all of us here on campus,"
said Roberts. "It's a double win."
The cars can hold one to four people, depending on the
model, and are equipped with windshields, wiper blades,
rearview mirrors, headlights and taillights, seat belts,
reflectors and parking brakes. They can be legally driven on
roads with speed limits of 35 miles per hour or less,
although they cannot exceed 25 miles per hour. Staff members
can drive them on campus roads, but they may not drive them
on sidewalks, walkways, or bikepaths.

Brand loyalty, growth drive auto sales increase in valley
Coachella dealers optimistic as figures beat national trend
By Lou Hirsh The Desert Sun January 14th, 2003
[...]
Sherr noted that the valley has a high number of retirees,
many with disposable income to spend on higher-end cars, as
well as an influx of younger residents setting up new homes
and shopping for big-ticket items like autos.
"If people are buying second homes, there?s a good chance
they?re buying second cars," Sherr said.
[...]
Sherr noted that electric-powered vehicles like Chrysler?s
Gem are having a quiet but steady impact on valley auto
sales.
He said sales of the two-passenger Gems have been rising
noticeably since their introduction in 2000, and they are
proving popular in gated communities, golf course
developments and retirement villages. The cars sell for
$4,000 to $6,000, with their prices kept low in part by
government incentives to produce and sell them.
Sherr said California sells more electric cars than any
other state, and the Coachella Valley is among the state?s
leaders in electric vehicle purchases.
"We went from selling two or three a month at our
dealership, to where we are selling 50 or 60 in some
months," Sherr said.
Lou Hirsch can be reached at (760) 778-4691.
