RE berlingos

Berlingos are cheap secondhand in the UK 1,000 to
10,000 pounds sterling, I think they are even chepaer
in France and Italy.

Apparently there was a period when the batteries were
delicate (late 1990s). I have heard of a few later
ones with duff batteries too, probably due to lack of
water.

Be aware that the berlingo motor is only rated at 15kw
continuous / 27Kw peak. I don't know how far you can
stretch this , the motor cooling is very minimal as
standard, maybe you could get more power by increasing
the air flow. I had to recondition have the comm
skimmed on mine at 20,000 miles so maybe if you put
more amps/volts thorugh it it would need more
maintenance.  The controller is watercooled and has
thermal limits ot the current, it could probably
handle more volts and amps without modification but
I'm no expert.

The motors are about 2 foot long and a foot diameter
and I guess about 100Kg. they have built in reduction
and differential.

I may be speaking out of turn here, but it seems like everyone is trying to
find a neater and sweeter solution to this issue and these solutions are
only making the system more complicated and prone to failure. Wouldn't it be
better to keep it simple?

Brake lights on controller off.

Accelerator at zero controller off.

Also, maybe turn the thinking around. Make it a passive instead of active
system. Instead of thinking: "If this happens then turn it off." Try
thinking: "If this doesn't happen then it won't turn on"

Approaching design that way often results in a system or machine that will
inherently fail to a safe mode.

By the way does anybody have a big red panic button on the dash?

Standard in all our kits.  Except we call it a "circuit breaker".

I am wondering if anyone has developed a hydraulically driven EV yet ?  There 
are many examples of wheel motors which already have mountings suitable  for 
suspension. Two wheel motors and a big hydraulic pump on the front of your  
motor which could be mounted _anywhere_ in your vehicle would make an  
interesting installation I think

You would lose a lot of efficiency by driving the pump with the electric
motor.

I thought this was one of the best off road transports ever designed.
However it is very heavy.  Even with 2000 pounds of lead acid batteries it
might get 20 miles of useable range.  The range you are asking is out of the
question unless you use a nuclear reactor.  Yes you can get the speed you
want.  Yes the horsepower.  No range available though.  As is I think that
vehicle is 6000 pounds or more.  You might rethink your conversion vehicle.
There are people in europe that do conversions.  Lets hope they pipe up.

I don't agree that it's minimal.  I have never overheated mine in
quite serious duty.  The blower attached works well and there are
temperature sensors in the windings.

, maybe you could get more power by increasing
the air flow. I had to recondition have the comm
skimmed on mine at 20,000 miles so maybe if you put

maintenance.

20,000 km is the replacement interval for the brushes.  Failing to
replace them regularly will damage the comm, but very little else will
in my experience.   That said I don't think it would want to rev much
higher.

Hey All, 

I have a quick question on modifying my charging operation to allow for 
charging of the aux battery at the same time the pack is charging. 

I was wondering how I could provide charger interlock functionality while still 
allowing the DC to DC converter to charge the aux battery while the pack is 
charging and not pull it off thew main pack during operation. Since the main 
contactor in my setup feeds the DC conv through only when the keyswitch relay 
sees ignition, the DC converter has no voltage during charge and therefore 
doesnt charge the aux battery.

I was thinking of a second contactor on the (-) side of the pack to disable the 
controller when the charger interlock is engaged but would prefer it be a 
normally closed contactor so there is only a 12 load during charge. 

Any experience, thoughts or ideas that can help me get at a safe and reliable 
solution?

TIA, Mike

Hello all

Everybody has used Wikipedia, right ? Well, Wikipedia is in need of your
help now.
No, no monetary contributions ( although these seem to be welcome as well ),
just a little of your time to get the facts straight on battery electric
vehicle and related topics. There is a massive "To Do" list posted on this
page:
http://en.wikipedia.org/wiki/Talk:Battery_electric_vehicle
As this list is probably most knowledgeable group of people in BEVs, i think
this call is worth shouting out here.

If you dont know how to edit wiki with proper formatting, or dont have time
for this, just write down what you know, your sources and where to get more
information on the Talk: page and the good people of wikipedia will
definitely take care of the rest.

thank you for hearing :)

--- Begin Message --- I have no idea about any details. Here is my personal opinion, for what it is worth:

A123 Systems makes the best high-power Li-Ion cells and wants to sell lots of them. The Cobasys folks make hybrid car battery packs. It only makes sense that Cobasys would want to team up with A123 Systems (and vice versa.)

From my dealings with A123 Systems, I have been _very_ impressed with their honest and sensible business approach. They make a high-quality product and they want to sell batteries to folks that make high-quality battery packs, etc.

It would be easy four wheel drive if you put a hub motor on each wheel.

Simple valves could turn it on and off.

Has anyone built a 4 wheel drive all electric?
It would get a lot of press.
It would have interesting climbing ability because of all that torque. If you wanted to maximise performance and throw away range with few batteries it might win some hill climb competitions for offroad extreme rock climbs which usually happen at slow speeds at high angles of attack.

Yes; they are common in industrial, mining, and other commercial vehicles. For example, fork lifts use electric hydraulic pumps and hydraulic motors.

It's less efficient than a gearbox (probably 80% vs. 95%). But, the convenience, durability, and versatility often makes up for it.

ROFLOL - well it'd work for me ;)

coincidentally, if anyone wants me to review their EV while I'm stateside I shall be in the greater DC area from Friday next week through till 1/20.

Please email me if you have a car you don't mind me videoing and reviewing for my YouTube Collection. http://youtube.com/profile? user=aminorjourney My aim is to get as many EVs as possible reviewed in a motoring show style. If anyone in the greater DC area has a RAV4EV still I'd love to drive it!

Cheers

Nikki.

P.S. Kate and I will be giving a guest talk at the EVA DC meet on January 16 in Bethesda on UK EVing ;)

I've seen 750+ downloads for a video uploaded two weeks ago. Actually,
750+ total spread across three videos that are diff. versions of the
same subject (identical key words, same length)

HINT. YouTube displays a "screenshot" from each upload. Not sure how it
selects what image but the three versions ended up "captured" as a
close-up of a (segway) wheel, a mug shot of some old guy and the third
an upperbody and head shot of a good-looking young woman, nicely
dressed and wearing a bike helmet. "*Her*" copy of the three vids gets
about 80% of the hits <smile>

So yah, if anyone has more EV content to upload, it'd be fun if EVers
stuffed this video ballot box.

There was some press awhile back over Ford's "Hydraulic Hybrid".
Instead of battery storage, it relied on pressurized tanks of hydraulic fluid. In fact since the energy storage comes from the compression of tank air above the fluid, it is more accurately termed a "Pneumatic Hybrid". As the fluid is used, it drains into a low pressure reservoir and will be pumped back into to the high pressure tank during regenerative braking or a slow recharge off the engine.

I was surprised hydraulics could be applied that way, I assumed viscosity would make it terribly inefficient for any sort of high speed movement. I don't think its real world performance has been proven, but you can try to look up details on it anyways.

There is a full-time position opening for a BMS designer in Boulder, Colorado.

Here are the details:

They need an experienced electronics person to design custom BMS for their Li-Ion battery systems. This person must have a good background in embedded systems, power electronics, data acquisition, PCB layout, and, of course, battery charge management. A love for EVs is a definite plus. :^)

This is a great opportunity for the right person. Boundless is moving in the direction of providing "turn-key" type solutions for cutting edge EV and hybrid battery packs. The electronics and BMS design is a key part of this effort.

If you are qualified and interested, contact Boundless Corp. at:
303-415-9029

Hello Mike,

It is easier to use a small on board 12 volt smart charger that is connected 
to you AC input for your main battery charger.  Every time you you have the 
main AC plug on, your 12 volt charger can come on at the same time.

This is what I do,  The AC from the main 50 amp input goes to a on board 20 
amp circuit breaker which the 12 volt charger is connected to.

I am use a Solid State Schumacher Model WM-5000A.  Current select of 2, 
10-30 amp.  It has digital voltage and state of charge indicators. It will 
auto stop the balk charge and then go into a maintainer cycle.

It will charge standard, deep cycle, AGM or Gel batteries.

I purchase my unit from Wal-Mart or from www.walmart.com.

Roland

That probably would be good, huh?  but a good photo shoot requires sunlight, 
and that has yet to happen while I am off work.  It's literally been lousy 
conditions whenever I have had the time for the last month (not necessarily 
raining cats and dogs, just lousy lighting, fog, drizzle, you name it).  I also 
would like to take pics highlighting some of the lighting changes, especially 
the rear lights.

We just moved, so it's on the list of things to do, but its waaayyyyyyy down on 
the list.  If it is sunny this weekend, then I need to wash/wax all the 
vehicles, and I'll take pictures then.

It came that color, and I like it, but it isn't the greatest paint job.  But it 
looks OK from a distance, and doesn't expose any metal to the environment, so 
I'm letting it go for the moment.  Replacing the shocks/struts and getting an 
aftermarket subwoofer amp are tops on my list for the car right now.

The squirrel conversion looks great!
I must say it really helps that is in that electric blue color.

Can you take some pictures with the car out of the garage though?

--- Begin Message --- sounds good, but what happens if you are on a steep hill and you need to hold the brake pedal while you press the go pedal to get the car moving without rolling back into the car behind you?
A brake-on-motor-off switch would not work for this situation.

As I said before, I think a good way is to use the throttle-off detector and cut power if the battery current doesn't fall. My plan is to have this on/off controller as a supervisor. It would monitor and do safety checks, and also report the data to the vehicle display on the dash, so its measuring battery current already. Though I'm not sure exactly what it does, it seems similiar to what the Zilla hairball does, but this supervisor would work independent of any particular motor controller.

John Wayland figured out how to do this very cleverly several years ago.

As I recall John placed a magnetic reed switch right next to the motor cable so that it would open when current was flowing to the motor. He put this reed switch in parallel with a brake pedal switch that would open when the pedal was pressed. This whole thing was placed in series with the main contactor "seal in" circuit.

If there was a large current flowing to the motor, and you put your foot on the brake, it would drop out the main contactor.

        Quite clever, isn't it?

Wouldn't it be possible to build a circuit that:

Disables the contractor whenever the brake lights come on AND there is
current (or voltage) on the motor? Wouldn't that clearly indicate the
drivers desire to stop even though there seems to be power delivered to
the motor?

Somebody able to draw up a quick circuit?

--- Begin Message --- Here is an update on the article coming out in the world's largest automotive publication, Car and Driver. John Wayland had given me a call after spending time on the phone with the fact checker for Car and Driver. Here is what I am allowed to tell you. The article will be out in the April issue which comes out in March. For those who have followed Car and Driver over a long period of time know, they aren't what you might refer to as a tree hugger type of publication. Some may say they are far from it :-) Well piloting a low 12 second EV may have changed their attitude slightly. I'm sure it did to the driver, Ted West, who came to the NEDRA Nationals this last fall. John say's that it is a very positive article. That being said, I just can't wait to get my hands on a copy of it! This is also a major milestone for NEDRA and for EVs for the year of 2006, actually having Car and Driver send a writer and a photographer to an EV event. Yep, all in all 2006 was a pretty good year for EVs but 2007 is shaping up to be even better with new national TV coverage coming up and other things I can't talk about yet.

Yes PML Flightlink, makers of printed circuit motors built this 4 
wheel drive Mini with 640HP using 4 of their wheel motors

Check it out... http://tinyurl.com/nqddx 

If I had the money I would get onto that...

Their webpage is here...
www.pmlflightlink.co.uk   not bad progress for a company who started 
making computer pancake motors for drives and the like !

Ah yes viscosity, you could always run it slowly and gear it up to 
take benefit from the huge ammounts of torque which hydraulic motors 
can create, maybe.
