My First Post - Does anyone know anything about the Solectria DW Electric Car?

Post by waasiFMC » Mon, 29 Jul 2019, 18:13

Hi AEVA Members,

Just hear to understand EV and have a Project car to learn and experience the EV life but I need to do some learning first and maybe you guys can help me.

Firstly, Has anyone got a Daewoo Cielo Solectria DW Electric Car here or have much experience with them? or know anything about them and its hardware?

Got some questions also, Please excuse my Noobness -

1 - With the Batteries, If the Motor is a 240v AC motor, Does that mean if I buy 12v Batteries x20 will = 240V or am I missing something?

2 - If I use 24v Truck batteries would that mean I only need to use x10 to make 240v?

3 - If I wanted to test the AC motor on my car, is there a way to test it beside using Batteries? like the Main Power? or Just a handful of batteries to just see it turns?

4 - How do you work out what Change controller to get or what determines this? The batteries you buy? Ah?

Thank you for all your help and knowledge. I had looked very hard for the Seach function on this forum and couldn't find it at all so had no choice to but make a Post.

I'm from Victoria S.E side.
Again Thank you for your time.

A solectria in Australia, that's somewhat unusual.
Can you take some pictures, for curiosity sake?

If the motor is 240vac you will likely be dealing with a 320v battery or there abouts. So maybe 16 12v batteries.
Do you know what batteries are installed at present?
Lead acid 12v is usually to heavy, though if solectria have set the vehicle up for the weight you may be Okay

Yeah I doubt there is actually one in Oz.

Really you can convert anything.
I'd expect there to be something else in Oz that would be better value.
So the short answer is NO but the long answer is YES.

To make a Sinewave From DC the DC needs to be 1.414 SQRT(2) times higher than the AC.
So as stated above you need 240V AC x 1.414 = 340V DC

The motor controller will have a VOLTAGE MINIMUM setting.
If you are below this the motor controller wont turn the motor.
For example you may need 285V DC minimum.
Rectifying mains will get the Voltage but only 2kW of power.
It might work but I don't recommend doing this for safety reasons.

Change?!?
You mean charger?

Most battery packs for ev's are large so it would be difficult to charge them too fast from a power point.
From a power point of view if you intend to charge from a regular power point get a 2400W charger.
If you have a 15A power point get a 3kW charger.

Next is the terminating voltage (maximum charged voltage of the battery pack).
Then after is the chemistry try eg lithium, Lead acid etc...

You need to know the voltage and chemistry of your battery pack before you can get the charger.


Ask more questions - get more answers ;)
So the short answer is NO but the long answer is YES.

Yes I will take some photos, but the car from the Article which is in the link above is the exact car I have bought.

The car did not come with batteries or a charger. but I know what it did have in it. Yes the car suspension is Setup to take the weight.

Yes there are better cars out there, but I liked that fact its all done professionally and it has an AC motor which is better from my understanding.

Hi Steve,
Yes that is the car I have got. Yet it was stored for the last 9 years so I hope to give it a new life. First I need to learn the basics before I start touching the car.

Hi Richo, Thank you for your reply to my questions.

I have very good hands-on skills working with cars and engine conversion and all that but EV is new to me and I'm keen to learn, But first Baby steps by asking questions.

1 - Thank you for clarifying that so the number I have to reach is 340v

2 - Thank you for that, As the car has the capacity of carrying 100 cells at the front and 100 cells in the back. I was thinking if 10 car batteries front and 10 back but I am still learning about the batteries and all that.

3 - Yes you are right there would be min to make it work. Guess there is no other safe way then getting batteries. but im worried to spend all that money to find out the other components are not working or damaged so just trying to see if we could test it first.

4 - Yes sorry Charger. Yes guess I need to start working out which way to go with the batteries. Also could I get the battery packs from cars like Nissan Leaf or Tesla and make it work?

Yep or more specifically it will be the settings in the motor controller.
Perhaps you could find the model number of it somewhere.

Ok back when the car was built car batteries (lead acid) might have been the most viable option.
These days flooded cells are really a big fat NO.
Seal lead acid (SLA) or Gel Cells are the next step up - they have better deep discharge than a car battery.
Next will be Prismatic LiFePO4 such as Winston, thundersky, Sky Energy, Calib cells.
After this will be the 2nd hand cells from Leaf, Miev, Tesla etc but may come with complications and limited availability.
Then various lithium chemistry pouch cells and cylindrical cells get you to the top end.
But really you should be able to use any of them within the voltage setting limits in the motor controller.

Select your battery based on physical size, chemistry, cost.
Get a charger to mach the batteries.

Is it still registered?
So the short answer is NO but the long answer is YES.

No it's not registered and has not for the last 9 years sadly.

Thank you for the breakdown on the type of batteries and so on.

I have got some photos of the hardware and will attach them in a new post.

No I think it is for the Actual Drive Motor which is AC. judging by its size.

Yup, the big umoc440 50kw drive is definitely traction.

If still wanting to test it, I have a big stockpile of nhw10 sticks, probably enough to build a pack of high enogjh voltage. Capacity would be tiny, but they're cheap.

A full 40 stick pack is 288vdc, which should be enough for the van to move under its own power, to confirm operation of the mc and motor

Yeah I am interested, I have sent you a PM but unsure if it actually sent. Let me know the price and will see which direction to go with it.

Hi.
WOW!
This is my first post here. I’m always busy but couldn’t resist replying after hearing about another DW.
I’m in the UK and have a Solectria DW!
I’ve never had any success with finding another one so as you can imagine I was surprised to bump into your post.
I was under the impression that mine was the only surviving vehicle left! I have lots of info on my car, (all were slightly different) which I was told by Solectria was the only car in Europe. They only made about 14 cars.

Hi Phil,
Wow there you go there is another member here with the same car!

Did you have any photos of the car? would love to see what your car looks like and what it has on it.

Would love to find out about the Software to access the unit and also the batteries and overall how your experience with them has been.

So they only made 14 Cars in total around the world? That is amazing, wonder what number my car is, how to check?

Hi Waasi.
I wasn’t a member until I spotted your post last night. Obviously I couldn’t reply until I joined.

It will be very hard to find any info on the car, there just isn’t any out there, the occasional reference, a very few stories and the Autospeed wright up is all I have ever found. There aren’t even any pictures or photos. It is incredibly rare, -BUT NOW TWO OF THEM!! I managed to find out a lot of info from Solectria before they disappeared. They were interested in having the car back at one point. Apparently it was not on sale to the general public as it was a test/demo car commissioned by GP Batteries and went to their dealers only. All were exported from USA, mostly to Asia.
The motor, box, main drive controller, dc to dc converter, Data Acquisition Unit, air-con motor and controller, most of the system switches, amp/hr display and the charger etc are all the same/similar to the Solectria Geo Force Metro.
Some, maybe all the cars were slightly different in their battery power depending where they were to be sent.
Voltages were as far as I know all 240 DC, from nickel metal hydride GP batteries. The amp/hrs were varied. Think mine was originally 20 of 12volt x 60amp batts. The original batteries are or were still available but at a horrendous price.
I got mine on eBay probably 10 years ago and I occasionally work on it. It isn’t on the road (no MOT). -It has however been driven round the block a few times! -very successfully. I’m just too busy to finish it at the moment.
I purchased it with the intention of using all the parts for a project but quickly realized it was too rare for that so decided to put it back to as near original as I could, -that was impossible being in the UK... most parts are available but I couldn't find anyone to send the bits from USA at a reasonable rate. (Probably spent £7000 - £10000 so far on parts!!!) I have had to source the parts from Singapore and USA. I have mainly rebuilt it from pictures and finding info on other Solectria vehicles.
I will dig out some pics and info for you. Mine is plain white. Right hand drive. Running temporarily on standard lead acid battery’s at the moment. 20 x 12volt, 50amp/hr.
They definitely only made 14 cars.
Chassis number should be on the registration docs, if you have them? Chassis number is also stamped on floor down between drivers side seat and inner cill, also under bonnet. But I’m afraid that won’t tell you which one of the 14 it is.

Will get back to you soon.
Phil.

Hi Wassi.
I’m a mechanic so I had no problem to round up 20 old car batteries to get the voltage I needed for testing.- that was the easy bit....
If you haven’t got the Data unit running then nothing will work even if connected to the 240v batts. The (DAQ) Data Acquisition system is in the boot under the rear parcel shelf. •Have you still got it?• It has about 50 to 100 wires connecting it. It checks all the voltages and switches (forward/reverse/neutral and throttle etc) are in the correct position before connecting the main traction battery to the motor controller. It also controls the charger and monitors the battery temperatures in the front and rear battery boxes and also switches the cooling fans on. -And controls the alarm outputs.
So basically you will have to fool the main motor controller into thinking all the inputs are safe. It’s quite easy to do if you download the info on how to connect the controller.

I haven’t got the DAQ as it was removed from the car before I got it so I had to bypass all the safety inputs on it. It is LIVE 240 volts dc when the main batts are connected so be carful if it is removed. I considered the DAQ not to be necessary as it’s main job was recording all the battery voltages when running so that GP could monitor and adjust the controller to learn about the power usage and the batteries.(& charging)
I’m not sure that I should say that you can bypass the safety input, it should only be done if you know what you are doing! Remember the voltage could kill. Take precautions. Make sure the wheels are clear of the ground when connecting the motor controller. You never know what could be faulty.

You only have to bypass it if it’s not working. Or not fitted.
