Hey Jim,
It looks like you had a good time Saturday. The way Dennis Bracket Races
the CE-V just like any other gas/fueler car shows how EVs are capable of
holding their own.

In a Zilla, the motor volts and amps may not be the same as the battery
volts and amps at certain loads and rpm of the motor.
For example:
My EV at 30 mph at 2000 rpm, the motor amps is 200 while the motor volts is
60 volts while the battery amperes reads 75 amps at 172 volts on a 180 volt
pack in a gear ratio of 5.57:1
As the speed and rpm gets higher in the same gear ratio, the motor volts is
over 200 volts and the ampere is over 350 amps at 80 mph at 6000 rpm while
the battery voltage reads as low as 100 volts at a battery ampere of 650
amps.
The most important gage I have is the motor ampere gage, which is a large
one right in front next to the tach. If you are not using a motor amp gage
and thinking that the battery amps is the same amperes as the motor amp, you
could be pulling 300 to 400 amps on your motor while you think you are only
pulling 100 amps on the motor using the battery amp meter.
Your motor amp meter should be red line for the continuous running amperes
that your motor is spec for.

320KW has the word "peak" in front of it.
1000A is (implied) to be continuous.

Not very good, actually. High internal resistance, and large variations
between cells. But... they did have twice the amphour capacity at low rates as
nicads. The label says:
Harding Energy Systems
Grand Haven, MI 49417 USA
(616)847-0989
Rechargeable Nickel-Hydride Battery
AA size -- 1.2 volts -- Capacity 1000mah

I originally had four; two have survived to this day. I just did a quick test
and they still measure 1.244v and 1.252v open circuit, and deliver 245ma and
325ma short circuit (pretty amazing for a 17 year old cell)!

Right. It *has* to be! but, would anyone would want to make them with this
same formula? Probably not.

It should be pretty easy to verify since you have an E-Meter watching
the battery side current. Just crank the current limit down
ridiculously far and then see what the peak current reading is that you
can get on the E-Meter. If the vehicle performance is unacceptable then
turn up the adjustment a bit and repeat until you are just able to 'peg'
the E-Meter at between 500-511A indicated. At this point, your battery
side current should be very similar to what it was with the prior
DCP600, so if the voltage problem persists I'd start by looking at
E-Meter wiring near the controller or motor loop wiring.
Hope this helps,
Roger.

Green Wheels: Tom Hanks Picks Up First Electric Scion XB
Filed under: transport michael @ 10:33 pm Feb 17
[
http://www.ecorazzi.com/wp-content/uploads/2007/02/tom.jpg
]
Tom Hanks is a big fan of electric cars. Back in the day, he was
one of the first celebrities driving around in GMs ill-fated
EV1. (You can check out a clip of him exalting the virtues of
this electric car on Letterman here.
[ http://youtube.com/watch?v=3ldmWebflUU ]) He also owns a
hybrid and has invested in a company that takes hybrid cars
and converts them to all-electric.
So, it comes as no surprise that Hanks was one of the first
people to drive away (quietly) in a brand-new all-electric Scion
XB. Unfortunately, you wont find these down at your local
dealer. Hanks had his specially made from a company called AC
Propulsion
[ http://www.acpropulsion.com/releases/02-15-2007.htm ] that
converts the Scion XB model using a system called the Ebox.
>From the article,
[
http://www.autobloggreen.com/2007/02/17/first-ebox-from-ac-propulsion-delivered-to-tom-hanks/
]
The eBox is a conversion by AC Propulsion costing $55,000 not
including tax or the Scion XB that is required. The vehicle uses
an AC motor driving the front wheels, and uses 625 pounds of
lithium-ion batteries that enable the vehicle to run for 140-180
miles between charges. The top speed of the vehicle is 95 mph,
and charging the 355 volt pack takes between 2 and 5 hours
depending on the mode you choose and the available voltage to
charge from. The vehicle also supports vehicle-to-grid power
sharing
Before leaving the dealership, Hanks (who is a space buff) had
this to say,
There are three electric cars sitting on the moon, and now
another one in my garage. The eBox makes even more sense in Los
Angeles than in the Taurus-Littrow Valley of the moon. I can
drive all weekend, hauling dogs and helping my friends move, and
the only reason Ill need to stop at a gas station is for beef
jerky and lottery tickets.
Yea, and unless I grab a winning lottery ticket, you wont see me
driving around in one of these anytime soon! That range is nice,
but for more than $70K, Im almost in the Tesla Roadster price
bracket. I still believe were about 3-5 years from affordable
electric vehicles with decent range and charge-time. Till then, I
applaud people like Hanks for taking the first steps in
supporting the industry. After watching Who Killed The Electric
Car, the whole thing seems a little like déjà vu.

There is only one place it can go: between controller and motor, as the
motor is normally directly connected to the controller with 2 short thick
cables. The shunt goes in one of the two cable runs.

PowerGenix Selects Manufacturing Partner to Produce Sealed
Rechargeable Nickel-Zinc Batteries
High Volume Forecast for the Evolution of Thomas Edison's Work
Prompts Action By: PR Newswire Feb. 16, 2007 09:24 PM
SAN DIEGO, Feb. 16 /PRNewswire/ -- PowerGenix, Inc., a leading
developer of high-rate discharge, sealed rechargeable nickel-zinc
(NiZn) batteries, announced today that in order to prepare for
its ramp-up phase, it has entered into an agreement with Hunan
Corun Hi-Tech Co. Ltd, for high volume production and Asian
distribution of its innovative NiZn batteries. Maybe Thomas
Edison was right after all. Mr. Edison's work on the invention of
the Galvanic battery incorporated nickel & zinc. And now, after
other elements such as Nickel Cadmium (proven to be toxic),
Nickel Metal Hydride (expensive), Lithium Ion (unstable) et al,
Nickel Zinc is proving to be safe and effective for many high
power applications in addition to being the friendliest to the
environment.
"Nickel Zinc has always been the holy grail of chemical
composition," stated Joseph A. Carcone, Vice President of
PowerGenix. "The limiting factor has always been reliability and
cycle life, which PowerGenix has solved. First, the PowerGenix
'secret sauce' electrolyte is a deterrent, as is their separator
material and the sealed cylindrical spirally wound design. In
fact, we own many patents on the solution," added Mr. Carcone.
"Because of the fervent response we've already experienced to our
new nickel-zinc batteries, particularly from a sampling of the
most demanding users of nickel-cadmium batteries, it became very
clear that we needed to select a manufacturing partner that could
respond to the unique demands of the cordless power tool market.
This made the selection of our manufacturing partner a critical
decision," stated PowerGenix's chief executive officer Dan
Squiller. "As we ramp our production, Corun's technical
expertise, innovative manufacturing techniques, and commitment to
nickel-zinc chemistry will help ensure we meet the existing and
evolving needs of the marketplace.
All of this was taken into account with the selection of Corun as
the ideal manufacturing partner that possessed the right balance
of technical innovation, reputation for quality products, concern
for the environment and the capability of quickly scaling to the
anticipated demand." After a thorough search for the right
manufacturing company that not only had the necessary production
capacity but also possessed mature manufacturing processes and
controls, we chose Corun. They represent everything we're looking
for in a manufacturing partner," commented Mr. Squiller.
About Hunan Corun: HUNAN CORUN HI-TECH CO.,LTD was founded on
June 8, 2001, located at ChaoYang Hi-Tech Park, YiYang, Hunan -
China, and has a plant space of 45000 square meters and a daily
production capacity of 800,000 cells.
Corun is focused on product quality and environmental protection
to the point that their company tenet is to "avoid waste, save
resources and protect the earth." At the beginning of 2002, Corun
set out to build environmental management system ISO14001, and in
April 2004 received the authentication of their environmental
management system. They are certified by UL, CE, ISO9001: 2000,
IS014001: 1996, RBRC, etc. They are well suited to transition
PowerGenix's rechargeable NiZn batteries from prototype
production in San Diego into high volume production for worldwide
distribution.
"PowerGenix's innovative nickel-zinc battery chemistry is a
revolutionary step in achieving long life cycle and high specific
energy. We're excited that we were chosen to produce such a
groundbreaking and environmentally-friendly technology," stated
Mr. Chen Zhen Bing, General Manager of Corun. "Because we are a

While I agree with the three choices, it seems that you are assuming
that the only PWM controller option is to use a series controller.
Perhaps the list of options needs to be extended:
a) repair the Soleq controller,
b) replace it with a Curtis or other sep-ex motor controller
c) replace it with a Curtis or other series motor controller,
d) replace it with a contactor controller.
I think the Soleq was a 108V system? Not sure how many amps. Curtis'
sep-ex offerings go up to 72V and 400A, which might be acceptable
depending on where the vehicle is driven. Zapi goes up to 96V and
either 500 or 600A, IIRC, which might provide near original performance.
Cheers,
Roger.

EVLN($29k NC grant buys 4 Winston-Salem parking-meter nEVs)

City receives grant to help buy 4 electric vehicles
Carts, to be used by parking-meter readers, are part of efforts
to reduce air pollution
The GEM eL is one of the types of electric vehicles the city may
consider for parking enforcement.

City fleet officials have been awarded a $28,800 state grant to
help buy four electric vehicles that will be used by
parking-meter readers downtown.
The Winston-Salem City Council is expected to approve the
purchase in the next budget. The carts will be the first
all-electric vehicles added to the city's small but growing fleet
of reduced-emissions vehicles. The fleet is one of the city's
contributions to a regional effort to fight air pollution.
The grant will cover about 60 percent of the estimated $48,000
cost for the four vehicles, while the city will pay the rest.
City fleet officials plan to get bids from several
electric-vehicle companies and hope to have the carts on the
street by August.
The carts will join a low-emissions fleet of 10 cars and trucks
that run on compressed natural gas. The city started buying the
natural-gas vehicles seven years ago and bought six gas/electric
hybrids a year ago.
The current three-wheel, gas-powered vehicles used for parking
enforcement are being replaced because they are about 10 years
old and require a lot of maintenance, said Sandy Barfoot, the
director of the general-services division who manages the city's
vehicle fleet.
Although those carts are driven only about 2,000 miles a year,
the motors in them run for long periods.
Because they are used in a limited area - downtown - pulling them
off the street could make a difference in emission levels there,
Barfoot said. "They sit and idle a lot," he said.
The grant to help pay for the carts was offered through the N.C.
Solar Center as a part of the Clean Fuel Advanced Technology
project, sponsored by the N.C. Department of Transportation, the
N.C. Division of Air Quality and the N.C. State Energy Office.
The purchase conforms to a formal policy adopted by the
Winston-Salem City Council in April that calls for staff members
to consider environmental factors when buying vehicles, rather
than just taking the lowest bid.
Barfoot said that while city staff members have long looked at
factors such as fuel efficiency and emissions when buying
vehicles, the final decision was generally dictated by the bottom
line.
Now they are required to look at alternative vehicles, even if
they cost more money. Although it's still up to the council to
decide on a purchase, they are looking at more options.
"We usually ended up getting what we could for the money,"
Barfoot said of past purchases. "I won't say we didn't consider
environmental and fuel-cost impacts, but we are definitely
putting more emphasis on it now, and we're not alone. Every fleet
newsletter I get shows that people are changing their
attitudes."
Although the alternative-vehicle fleet is tiny compared to the
total 1,600 pieces of rolling stock owned by the city, its
growing presence sends an important message about the city's
attitude toward improving air quality said Ginger Booker of the
Piedmont Triad Council of Governments in Greensboro.
Booker helps coordinate efforts by the Triad Early Action
compact, which was formed in 2002 in anticipation of the U. S.
Environmental Protection Agen-cy listing many of the region's
counties - including Forsyth - on the national Dirty Air list.
Its creation allowed Triad counties to address local ozone
air-pollution problems on their own rather than have a solution
forced on them by the EPA or state officials.
Ozone is a highly reactive form of oxygen that is unhealthy to
breathe and damages trees and crops. It exists naturally in the
upper atmosphere. Ground-level ozone, or smog, is formed when
vehicle exhaust and industrial chemicals mix on hot, sunny days
between May and September.
Because of both state and local pollution-control measures now in
place and a decline in manufacturing, emissions that contribute
to the region's ozone problems have dropped.
The region is now in line to meet a federal deadline for
ozone-healthy air by the end of the year, Booker said.
She also said that the city's new vehicle policy - the first of
its type in the region - signals that attention to air pollution
won't wane once the federal deadline is met.
"It was important because it puts the city in the right
direction," Booker said.

Hello,
I am newbe to your list.
I have been considering doing a EV conversion, using a
1970 BMW 2002, a neat little car that I own.
I am looking at a direct drive AC conversions, and it
seems the only suppliers of (affordable) motors and
controllers out there are MetricMind
http://www.metricmind.com/ and ElectroAutomotive
http://www.electroauto.com/index.html.
Has anyone out there done an AC conversion?
With parts from these places?
Has anyone dealt with these companies?
Are there other suppliers that I should look into?
Thanks in advance for the advice.
Andy

EVLN(MIT's The Car 2.0 : stackable EVs)

THE BIG DRIVE The Car, 2.0
By Robert Weisman, Globe Staff February 18, 2007
Researchers at the MIT Media Lab envision a fleet of lightweight
stackable electric cars that can help reduce congestion and urban
energy waste.
CAMBRIDGE -- Will the car of the future be foldable?
That's the vision of a team of researchers at the Massachusetts
Institute of Technology's Media Lab. With backing from General
Motors Corp., they are building a prototype of a lightweight
electric vehicle that can be cheaply mass-produced, rented by
commuters under a shared-use business model, and folded and
stacked like grocery carts at subway stations or other central
sites.
It's called the City Car, and the key to the concept lies in the
design of its wheels. Dreamers have been reinventing the wheel
since the days of cave dwellers. But the work underway in "the
Cube," the Media Lab's basement studio, may be the most ambitious
remake yet.
The MIT team has transformed the lowly wheel into a sophisticated
robotic drive system that will power the City Car. Embedded in
each of its four wheels will be an electric motor, steering and
braking mechanisms, suspension, and digital controls, all
integrated into sealed units that can be snapped on and off.
And under the hood . . . well, there won't be a hood on the City
Car. Just an eggshell-shaped glass plate -- part roof, part
windshield -- framing the modular cabin and stretching almost to
the chassis.
INTERACTIVE GRAPHIC: The City Car
[ http://www.boston.com/cars/news/articles/2007/02/18/citycar ]
"We're eliminating the internal combustion engine," said Media
Lab research assistant Ryan Chin , studio coordinator for City
Cars. He said the four electric motors will enable a more
efficient use of power by also dispensing with the transmission
and driveline. "We're removing as much hardware from the car as
possible."
In its place will be software that sets passenger preferences,
changes the color of the cabin, controls the dashboard look and
feel, and even directs drivers to parking spaces. "We think of
the car as a big mobile computer with wheels on it," Chin said.
"This car should have a lot of computational power. It should
know where the potholes are."
And like a computer, the car will start with the push of a
button. Instead of a steering wheel, it has handlebars, akin to a
scooter or motorbike. But the ride will be more like a
traditional car, though smoother and quieter, Chin said. The body
of the car will be made of lightweight composite material such as
Kevlar or carbon fiber.
Among the car's other design departures are its folding chassis,
enabling it to be stacked at designated parking areas across an
urban area, where it could also be recharged. It also has a
zero-turn radius, courtesy of a wheel configuration that provides
omnidirectional motion. For the City Car, the traditional U-turn
will be replaced by an O-turn, ideal for fitting into tight
spaces.
The concept of the City Car was hatched by the Media Lab's Smart
Cities group, as part of a strategy for reducing carbon
emissions. The team is being led by William J. Mitchell ,
professor of architecture and media arts and sciences.

silence.
Its pretty neat, said Force owner Jay Whelan. Its absolutely

ENVIRONMENT: Ridgefield couple's car gets many miles to no
gallons By Chipp Reid, Ridgefield Press Staff
Lisa and Jay Whelan are all smiles thanks to their own clean
initiative, their Sloectria Force electric car. The engine has no
radiator or internal combustion parts. Chipp Reid photo

>From the outside at least, there is no way to really tell the

Turn the key on a gasoline-powered car and the result is the

the key on the Force and the result is
silence.
Its pretty neat, said Force owner Jay Whelan. Its absolutely
quiet. There have been times when my wife has pulled in the
garage and I couldnt even hear it. I turned around and it scared
the heck out of me because theres the car.
Mr. Whelan and his wife, Lisa, bought the Solectria electric car
six years ago. Solectria, a Massachusetts-based company, builds
the car around the chassis of a Geo Metro. However, while the car
may look like a Metro, its internal workings are completely
different.
The Force has no engine, just an electric motor that powers the
drive train. Theres no need for oil or gas and it also doesnt
need a radiator since it can never overheat. The front engine
compartment is spacious since the motor is relatively small. A
set of six truck batteries stores the electricity and those are
in a compartment in the trunk.
Theres no maintenance, Mr. Whelan said. Ive had to change the
wiper blades, thats about it.
Turning green
The Whelans bought their electric car as their answer to how to
help the environment. Although Mr. Whelen describes himself as a
conservative environmentalist, he said he and his wife wanted
to find some way to live green. They buy their electricity from
renewable sources such as wind and solar through the Connecticut
Clean Energy Option, use composting to help reduce garbage and
do a lot of recycling.
Ive always thought about what can I do, said Mr. Whelan. When
we started to look for a second car, I thought about buying an
electric one.
Mr. Whelan said he expected finding an electric car would be
fairly easy. He had his eye on a GM model, only to discover the
automaker sold it only in California. Next he tried to look into
an electric RAV4, but once more could not find a dealer or even
get Toyota to answer his e-mails and phone calls.
I started to search on the Internet, Mr. Whelan said. Its an
amazing tool.
He came across Solectria in his search and looked into the
company. He quickly found out Massachusetts Institute of
Technology engineers run the firm and design the cars. Theyre
the best so I thought this would be a good car, Mr. Whelan said.
It has the best components and based on how few electric cars
are out there, I went with it.
The car arrived just in time for Christmas and his wifes
birthday in December 1999.
All he had to do was put a big red bow on it, Mrs. Whelan said.
Maintenance-free
The Solectria Force is arguably the simplest car to maintain
anywhere. Since it requires no fluids, it never needs an oil
change, coolant flush or gas filters. Each night, the Whelans
simply plug their car into a 220-volt outlet, the same type
clothes dryers use. The charge is good for about 50 miles, more
than enough to run chores around Ridgefield or even take a jaunt
as far as Brookfield.
Driving the car is simple, although it takes a little while to
get used to how quiet it is. When the generator starts up and
idles, it makes no noise. Once in gear, the motor hums as it
spins the drive train.
The car has three drive settings, each of which uses
progressively more power. Mr. Whelan said he has had the Force on
Interstate 84 and it drives OK. Its not the fastest car on the
road.
He said he can reach the Solectrias maximum speed of 72 mph
going downhill with the wind at my back.
Mrs. Whelan, who is a teacher in town, uses the car the most,
although not in the winter months. Cold weather can sap the
battery charge unless it is plugged in. I asked the Board of Ed
to install an outdoor outlet but they wouldnt go that far for
the environment, she said with a laugh.
Still, for getting around town or taking the children to various
events, the Force is the perfect car, Mrs. Whelan said.
Its a good car, she said. About the only thing you need to
worry about is the charge.
Plug and play
Mrs. Whelan admitted to nearly losing the charge one day as she
drove her daughter and a friend home from an event. When the car
started to slow down as it used its charge, she was able to pull
into a gas station that had an outdoor outlet.
I pulled up and plugged in, she said. They guy at the station
wasnt too happy about it, but after five minutes I was all
set.
Mr. Whelan said it takes about four hours to completely recharge
the batteries when they lose all of their charge. The batteries,
he said, are basic truck batteries. He recently replaced all six
by simply going to a local battery dealer.
The Solectria Force may be an environmentally friendly car, but
it isnt cheap. The Force cost $35,000, Mr. Whelan said, and that
was six years ago. The cost to charge the car, Mr. Whelan said,
is about $20 per month.
Although not the least expensive car on the road, the Solectria
has zero emissions, which is why Mr. Whelan bought it in the
first place. It also has him thinking about his next second
car. The Whelans own a pair of regular cars, a Suburu and a BMW.
As hybrid technology becomes more available, Mr. and Mrs. Whelan
said, they would consider buying a non-traditional car, thanks
mostly to their experience with the Solectria.
Its a great car, Mrs. Whelan said. We really like it.
