If the traction pack and the auxiliary pack are isolated from chassis
ground, you may do it.

If the traction pack and the accessory battery are tied together at chassis
ground, you will need an isolation transformer to do it.

You should earth the chassis when charging.

Hi All,

Can you use a PFC Charger (non-isolated) with a EV that has a common ground
between the traction pack and the Auxillary pack.

If so, do you have to ground the PFC charger case (Ac Earth) to the car
chassis (the car is AC earthed while charging).

On the other hand.
Cheers

greetings all-

i've been reading the list for a while and want to thank everyone for the excellent discussions that run through this list. the communal knowledge exchanged here is priceless and makes the learning curve for new EVers like myself much easier to climb.

but this mail is a more direct thank you to roderick wilde and father time. i am forever in their gratitude for helping me start my EV journey. what roderick didn't mention about their recent trip to LA for the WKTEC premiere, was that in all of the frenzy of EV promotion, partying and the like, he and FT managed to find the time and space in the trailer to haul an extra EV back to seattle for me.

the stars were in alignment when roderick and i first met at the seattle film fest showing of WKTEC. i was lamenting the cost of transporting a converted lancia i was trying to buy and he was bumming on the fuel cost of getting to the premiere. the rest just fell into place.

FT made it back to seattle on monday night and we met at a nearby texaco for the drop-off. i don't recall the last time i was that excited (actually it was my daughter's birth 2 years ago, but this was a close second). driving it the few miles back to the house i could feel the huge EV grin stretched across my face.

i don't think the deal would have worked if it hadn't been for roderick and FT reaching out to help a person they'd never met. and i could not have asked for a more expert team to help me out. thanks again.

so add one more EV to the northwest tally (sorry california). no doubt i'll have lots questions in the future

tony furr

btw- this car was not in the evalbum, so i'll add it as soon as i get the chance.

Is Gone Postal a Curbwatt?  I just got done working on one and they are all
aluminium.  You'd think they wouldn't weigh much more than the Rabbit that
they used all the suspension parts from.  Sure can carry a lot of weight.
It was set up for at least 96v of golfcart batteries.  I wonder what GP'd do
with a lighter pack that could put out the amps.  I'd be one nuts machine.
Already is.  LR>>>>>>>>>>

--- Begin Message --- The specs on this motor say: "Inverter duty: No", so it is not made to take the less clean waveforms and variable frequency from an inverter/motor speed controller running off DC - it is suitable for operation off AC mains power 50/60 Hz, fixed speed, I figure.

Nice price, though....

Yeah, I saw that in the archives, anyone tried one, certainly the right price. So it seems not much if anything available on the used/surplus large DC motor market.

Here is something, on sale only $465 :)

http://www.electricmotorwholesale.com/index.cfm?fuseaction=catalog.prodInfo&productID=68&categoryID=54

Now just need to figure out how to generate three-phase 230vac..
Now i'm thinking let's do this real simple, and use a 460v DC battery pack. With 4v lithiums, thats only 115 cells. Seems to defy the point of using AC vs DC, but my gosh, $3000 AC controllers?

is it safe to do this:

My car has a common ground. if i was to charge using a non-isolated charger like the PFC, can i jsut disconnect the common earth wire through the use of a relay. So that the automotive relay just connects the earth wire of the traction pack to the car chassis with the key ignition being turned on.

And then have the car chassis earthed while charging.


Cheers

What you all think?

You should earth the chassis when charging.

Is anyone on this list for hire to convert/build a vehicle, start to finish?
   
  I'm looking to set up a relationship and find out pricing for someone to
  build possibly multiple EV vehicles for a project I'm working on.
   
  Thanks,

Hi Chris-
Glad to hear the results of your testing. I've been thinking about it some more, and I think the fault I had that required a power-cycle reset on the 200-series(?) Vicors I was using (some years ago now - da' memory's kinda' rusty) was an over-current shutdown, rather than an under-voltage shutdown. What is the model/part number of the Vicor(s) you set up for John?
cheers,
Andrew

Hi Andrew,
I bench tested the module with a 600V power supply.  It did not require
power cycling to come back on after going below the under-voltage point.
According to the data sheet it looks like the module has an auto-restart
feature.  It checks every 2-20ms and restarts when the "fault" has been
cleared.

I don't have any other experience with Vicor modules so I can't comment on
if other modules do this.  I ran the unit both below the under-voltage  and
over-voltage and did not reset power in between, it always restarted on its
own.

Regards,
Chris Brune

Hi John-
The new DC-DC sounds great.
Have you actually confirmed that the Vicor will "come back to life" when
the voltage rises after the drag run?  I'm fairly certain that the
Vicors I've used required that you cycle the input power off and on to
reset them after they shut themselves down.  Something to check on...
Wish I could be there to see ya' run on Friday.
cheers,
Andrew

Hello to All,

The weather stilll looks perfect for this Friday night's attempt at the
11s, with the daytime temp. upped from 80 to 85 now. Tim reminded me he
had made his annual plans to take off with his buddies to party the long
4th of July weekend, starting 6-30 and blasting on through the 4th on
Tuesday, in Central Oregon. Soooo...the old man himself will be driving
the Zombie! Yup, I'm back in the saddle for this weekend's runs, and I'm
pumped about taking Tim's record from him :-)
My friend Chris Brune surprised me with a DC-DC he put together for
White Zombie.

Thanks Mike young

Yep, US Electricar truck. Just to let people know, we have been making serious strides towards getting these things fully operational. Between Mike, Andy, and myself we can fix a lot of the problems that have popped up.

Just don't rip out the controller and motor; it's nicer than you think.

Thats what I suspect.  None of this data is from external meters. Its all from 
the Zilla data stream.  So I set the motor voltage
limit down to 80V.  The truck went as expected only got up to 35mph, real 
slowly.  So I know the controller knows the voltage is
80V, but the data stream indicates 122V.  Also, while 140V seems reasonable for 
a sagged battery voltage I would expect the motor
to be that as well at 100% duty cycle. At 100% D.C., 140V Battery, the motor 
voltage indicates 214V.  The 53% exageration of Motor
voltage seems to be consistent.  So I have an e-mail to Ot asking the question 
if there could be a scaling factor off in the code.

I hear ya on the shift point.  With clutch slipping though more power isn't 
what I need.  Its easier for me to baby it in 2nd than
3rd.  Once the RPM is high enough it gets easier in 3rd.  Its not fast that way 
and hopefully I can get the new clutch in this
weekend.

Hopefully my change in e-mail addresses doesn't mess up the list.

Mike,
Anchorage, Ak.

--- Begin Message --- hmm, so what about the motor would limit it to 60Hz, or put another way, what design is changed to allow variable frequency operation? hey it at least can handle 50 vs 60 hz, bet it can handle 40 or 70 hz too. Actually was thinking that for an AC motor like these, you would want to use an automatic trans with a torque converter, and keep the motor spinning use lower voltage and power it up on throttle and then lock the converter. The nice thing of this setup is the accessories drive can run off the main motor and keep running when the car is idling.
gotta look into these AC motors some more..

The specs on this motor say: "Inverter duty: No", so it is not made to take the less clean waveforms and variable frequency from an inverter/motor speed controller running off DC - it is suitable for operation off AC mains power 50/60 Hz, fixed speed, I figure.

Nice price, though....

Yeah, I saw that in the archives, anyone tried one, certainly the right price. So it seems not much if anything available on the used/surplus large DC motor market.

Here is something, on sale only $465 :)

Now just need to figure out how to generate three-phase 230vac..
Now i'm thinking let's do this real simple, and use a 460v DC battery pack. With 4v lithiums, thats only 115 cells. Seems to defy the point of using AC vs DC, but my gosh, $3000 AC controllers?

hmm, so what about the motor would limit it to 60Hz, or put another way, what design is changed to allow variable frequency operation? hey it at least can handle 50 vs 60 hz, bet it can handle 40 or 70 hz too.

G'day all

OK, a little AC drive 101. This is "plain speak" as far as possible not "tech speak" or even less undersumblable "engineerlish". This does, however, need the reader to understand some of the basic electrical words and the concepts of those words.

Since we are talking about the standard industrial pattern of motor, it matters not if we are talking about a 50Hz motor, or a 60Hz motor, designed for a particular voltage and industrial market. This only applies to 3-phase motors, as "single phase" motors are actually split phase, with a bit of "jiggery-pokery" to split off a phase shift to make it run, but that shift componentry is frequency dependant, so gets upset if the frequency shifts much.

A motor runs at a given RPM for a given number of poles and a given frequency. At a given amps, the motor generates a certain amount of torque, more amps for whatever reason and it will burn out from excessive heat. A motor will attempt to follow the phase rotation of the AC voltage being applied, if it is lightly loaded, it will trail the rotation a little, if heavily loaded it will trail further. As it trails the applied voltage more and more the amps goes up and up (too far, too many amps, too much heat and burns out). Horsepower is torque x RPM, keep the torque the same, double the RPM and you double the hp.

Now here is the "big secret" of 3-phase motors: if you take a motor that is (for example) 200V 50Hz 10hp, and double the frequency, you have to double the voltage to be able to still drive the same amps into it. Same amps means same heating, double the voltage means double the horsepower! Of course if you take your 200V 50Hz 10hp motor and run it a 25Hz you can only drive it at 100V and 5hp, so it goes both ways. So our 10hp 50Hz motor is now able to be rated as 400V 100Hz 20hp. Double it again and you have 800V 200Hz 40hp. But the battery voltage needs to be around 1.4x the AC voltage, so our 200V motor running at 200Hz would need an 1120V battery voltage, which has the probability of being a little hazardous, to say the least.

So, we take our 200V 10hp motor to a rewinders shop and get it rewound with wire that has 5x the cross-sectional area, but only 1/5 the turns. It is now a 40V 50Hz 10hp motor, that takes 5x the amps to drive it, but the wire only generates the same heat as before since it is 5x heavier.

The drive transistors for a variable-frequency drive would have to be as big for our 40V 50Hz motor as they would be for a 200V 50Hz 50hp motor, since it is the amps that dictate the transistor size. So now our equation as above takes our motor out to 200Hz at 160V and 50hp, with a 224V battery, or 400Hz 320V 100hp 448V battery, much more of a manageable battery voltage.

If you have the time and money, and a vehicle that can position an industrial 50hp drive, you can "roll your own" AC system, 336V buss onto a 200V system 3-phase drive powering a 10hp motor rewound to 40V and reving to 300Hz (8400RPM for a 4-pole motor or 4200RPM for an 8-pole motor) generating 60hp (if it were a 50Hz motor originally). But the output shaft is still only that of a 10hp, so you may break it, unless you can increase the sise, or have a new shaft made from a much stronger material.

The drive transistors make the drive as big as an industrial 50hp drive, the motor shaft is under sized... so now the engineers step in to sort out something that is a balanced design for our on-road EV. He tweaks this and that and ends up with a design that integrates all sorts of things to get the packages that Victor sells with a 10 year guarantee.

So hopefully this has shown why although you can use an industrial motor for an on-road EV, it would not be to save money. If you have (for example) a CVT you may be able to "cook something up" that saves money by limiting the motor speed range or some other parameter. The motor above 40 Hz to 70Hz you are looking at do-able, but how are you going to use that in a vehicle?

Hope this helps, rather than wastes bandwidth.
