This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The intention is to power the electric car (EV) with an 11kW(modified), 3 phase industrial AC motor, controlled by an industry standard Variable Speed Drive (VSD) or Inverter. To be able to produce the 400 volts phase to phase the VSD will need about 600 VDC of batteries. A big thanks to the contributors on the AEVA forum: http://forums.aeva.asn.au/forums/

Meanwhile, I am getting good range figures now that it's warmed up a little here in Melbourne.
Here is the up-to-date range history since I have been driving the Vogue on electricity.
Range is based on 80% Depth of Discharge (DOD) of the battery pack.
The anomaly in October 2013 was caused by two high speed trips raising the average of only eight recharges. June 2013 had only five recharges. I normally recharge about 20 times a month in winter (every weeknight) and about 15 times a month in Summer.

I quickly took this picture on the way to work. I had another 5km to go. The over-100km-projected-range didn't last long as I was about to go up a big hill - nice to see though.
(Range is Remaining Range - I should rename it sometime.)
So on the way home I'll go over the 10,000km.

A recent Four Corners (a credible Australian current affairs TV show) explored the utterly stupid Australian government's bias against renewable energy development.
I really do not understand what the LNP (current government) think they are doing in this country.We are losing so much to a lie that the economy is in trouble and matters more than anything else.Australia is turning into the "bad guy", pushing it's coal when it should be planning and "doing" for a very doable sustainable future.
The discussion over electricity companies being in trouble from not "predicting" the private rooftop generation and renewable energy effect just points to a blinkered dumb attitude that failed to do basic research into clear trends. This is not "wise in retrospect". Many people predicted this and took action - just not some Australian power companies.
Of course this is just my opinion.

The Vogue is going strong - still waiting for the front end work but in no great hurry - other stuff has moved to higher priority (new kitchen floor, new puppy) so it's better to wait for couple of weeks.

Wire brushing them wasn't much fun. Here they have been wire brushed already.
Next was a coat of rust converter.
Then a coat of etch primer and a top coat or two.
Now I know that no-one likes to leave comments but is this colour too "loud". I still have time to paint them black.
They are a bit darker then it looks here. The Flash lit them up.
It's the same paint I used on the rear brake drums.
I read on some 4x4 and street car forums that it's a complete waste of time painting coil springs - oh well - they'll look better for a little while.

This will give me a chance to clean and paint the spare sway bar and springs this weekend (yes I found two spare Vogue springs under the house). That way I might be able to clean and paint the wishbones on a weeknight - minimizing the time that the Vogue is dry-docked. There is always the option of not bothering the clean up the wishbones at all but Laurel (better half) says I wouldn't be happy if I did that. She's probably right.
It would be really nice to have this front end - maybe one day I'll pull it out.....
(Not mine but off a similar Rootes vehicle!)
Meanwhile here is a picture of my array of SuperPro bushings.
(The bushings are missing from the lower shocker mounts packet as they are already installed in the shockers - see previous post):
Lower front shocker bush kit - SPF0718-80K
Control arm upper bush kit - SPF0730K
Control arm lower bush kit - SPF1059K
Sway bar to control arm kit - SPF1060-19K (19 is the sway bar diameter in mm)
(Control arm = wishbone)

The Holden H series shockers fit the Hillmans, Sunbeams and Singers(Humber Vogue) of the early sixties I'm told; so I just bought a set of Ultima Shock Absorbers off an eBay seller. They look about right - a minor change is all that is needed. Remove the bottom bushing and metal attachment and replace with a suitable Hillman style bushing. I have already bought some SuperPro SPF0718-80K bushings.
Cut around one side of the bushing where a lip has formed when the bushing was installed.
Drill out some rubber to make removing it easier. Try not to hit the metal.
Make a mess.
Place the shocker on a flat board and apply pressure with foot while pulling on the metal attachment with a big pair of multi-grips/pliers. A bit of rotational force helps.
Sorry no picture for this one but here the Holden style bushing has been removed (plus the one from the first shocker I did).
Apply some of the supplied lubricant to one end of the new bushing.
Squeeze the bushing in with a vice. The rag is just so I don't take too much paint off the shocker.

I haven't been very happy with the knocks and squeaks that the Vogue front end has been emitting for a while, so last week, having got a ball-park price from elsewhere and not been happy with it, I visited Knox Tyrepower (over the road from work) to ask for some advice. These are the folk I spoke of here that gave the Vogue it's Silicone tyres and who mentioned in no uncertain terms at the time (point 5 in this post) that the front end was "on the way out".
As soon as I indicated why I was there, Ross took me by the arm and led me next door to the mechanics (unrelated business). They all appeared to know about the "Electric Vogue" and were keen to help out. They had a good look under the car (up on a hoist) and confirmed we needed the upper and lower wishbone (control arm) bushes renewed. This is a job I do not want to do as by the time I get someone else to press the old bushes out etc. it will become a major pain - I know I'll want to re-paint the whole front end! Spring compressors scare me too.
So this may look a bit different in a week or two.
(Knox Tyrepower has put tyres on, and aligned, all the cars in our family for a past 12 years and I have never been disappointed in their advice or workmanship - no they're not family!)

All in time to drive it to work today.

First I removed the torn diaphragm. I also removed the two aluminium pieces at the sides so I could add more holes.
I had to temporarily un-thread the left hand front-to-back so allow me to get enough grip to stretch the side-to-side ones.
All done. The three middle side-to-side hooks are 30mm and are from the first seat diaphragm I bought - there is no reason I used them other than convenience. The Vogue originals and the ones I made were 20mm - you can see the difference.
The strange interleaving is because to front and rearmost straps would have been damaged by the webbing clamps if I had run the side-to-side trap across the bottom.
Cost of the Premium Webbing plus clamps for the base was $26 - with postage from (www.diyupholsterysupplies.com.au/home/) This includes enough for the passenger seat when it inevitably fails. The webbing is also heaps easier to put on and really easy to "get it right". My advise - don't bother with the diaphragm approach at all.
If this was being done while the seat was completely disassembled then you also would not need the aluminium pieces - just drill extra holes in the actual seat frame. Another time saver over what I did originally. The 0.8 stretch was about right for the base - I wouldn't change it.
I will post how it holds up over time but I really don't expect any problems at all as two or three straps can hold my 80kg weight easily - and there are eight.

I couldn't feel any vibration at all at 60 km/h and it didn't become evident until I hit 77 km/hr - even then it was only just detectable on a smooth road.
The vibration must have been my speed limiter when driving a I had to watch my speed very carefully on the way to work.
So it's definitely the tailshaft so it looks like I have to find someone who will do an ultimate balance.
The hugely diminished vibration and the new rear sway bar link bushes I put in a week ago (sorry not blogged) made for a very pleasant trip to work.
I have also sealed the front windscreen across the top in the body-to-rubber interface so I'll see how that goes this week. I have had some minor leaks. (I have a tendency not to use any sealant unless I absolutely have to.)

I had bought a 3 axis accelerometer from eBay a few weeks ago and on Saturday I added some connectors and wires so I could select any of the 3 axis to test. I choose the 'Z' axis output set to high-sensitivity, and added some orange bluetack (yes, really) to the bottom of the PCB to hold it on the motor frame.
The bluetack colour got washed out on this picture as and appears white.
Up the Vogue went onto axle stands with the rear wheels removed for safety.
I cleaned some road dirt off the motor frame and stuck the accelerometer on.
First trace. There was a lot of motor controller PWM noise but the vibration waveform was clear. I later added a 500Hz single pole RC filter which cleaned up the motor PWM noise - sorry not shown here. So the start point was 100mV P-P.
Then I tried in between but I couldn't do better than the result in number 2.
I increased my test speed to 4100 RPM (102 km/hr) and tried all again. The vibration increased to 50mV with the clamp in the best spot - about 1.8.
Picture here is with the clamp at about position 2.5.
I tried adding a small washer but there was a slightly worse result.
I tried cutting off 5mm of the protruding part of the clamp, but if anything, the result was slightly worse. It was hard to tell.
I'll drive it tomorrow.

I then simply divided the AH used by the distance and averaged these values for each month.
The range line (purple) is that figure divided into 16 - my pack is 20AH and 16 is 80% of the pack's AH capacity.
The result. (In Australia the hottest months are January/February - coldest is around June/July).
It's not aligned but here is the temperature graph for where I live. The grey area is the rolling average.

It only lasted a few months since I replaced it here.
So I will be installing webbing on the weekend.
It wasn't too tight this time - loose if anything - but obviously something about the application doesn't suit the TR6 seat diaphragms.
I'll document the lengths etc. when I install the webbing - it's a cheaper way to go and will be a better result as the webbing will give slightly rather than tearing like the rubber diaphragms.
Some pics - this first picture is from last time.
This time it simply ripped out two of the three metal anchors along the rear of the diaphragm. My feeling is that they are just not well made. The metal anchor strip was VERY close to the edge of the rubber and one of them just slid out.
I have packing material under the seat right now (stopping the upholstery from being under strain) so I couldn't get a picture but I did remove these from the aluminium strip that sits next to the seat frame. The one on the left has no rubber attached to speak of - the rubber just slid off either side of the metal.
BTW I weigh 81kg - it's not me!
More to come...

"Disturbingly well" I answered.
There was only 4 days where I didn't drive the Vogue - it was 40 degrees C or over all four days (see previous post).
Last week it was high 30's but I drove the Vogue anyway. I have kind of decided that a predicted temperature of 40 degrees C or over is the only time I'll leave it at home in the shade.
Meanwhile the "disturbingly well" comment was because the range is well up on my winter range. It's generally 85 km to 80% DOD and sometimes hitting 90 km. Keep in mind that I made it through winter with no heater so this is the battery pack temperature causing the change.
The line out of Blade Runner haunts me: "the candle that burns twice as bright burns for half as long".
If the pack degradation due to temperature is inversely proportional to the range increase (not likely - nothing is ever that simple) then it's not so bad but it really would be nice to have shaded parking at work!

Since I do not have under cover parking at work, I decided to not have the Vogue roast in the sun for the week and have swapped it into the garage. There, it should at least stay below 35 degrees C and keep the battery temperatures the same as ambient air rather than the 50 odd degrres they would get to under the bonnet (and in the boot) if it were in the sun.
My daughter is away so I'm driving her car. I didn't drive the Vogue Monday either but that was because the Super Snipe - our caravan tow car, has just had an automatic transmission service (complete with some fluid leak fixes) and I wanted to drive a few kilometers before we commit to dragging the caravan around the state with it.
So the Vogue is in the garage with the two completely redundant drip trays under it while the Snipe sits in the carport hopefully not leaking either.

The Vogue measures remaining range by figuring how far you have travelled on what fraction of the battery pack's capacity - then calculating how far you can go based on the remaining capacity. All this is done assuming only 80% of the pack capacity is available. It does this 3 times a second so the remaining range moves around a lot based on how you are driving. This technique would not work well in a commercial EV where people got an initial reading of a 33 km range after travelling 600 meters to the top of their street's hill (as I do almost every morning) - then the range esimate changed with every take off (as it does).
At just under the 10 km mark on my way to work I get a very optimistic indication. I only get a few seconds to take this picture before the lights go green and I missed a great picture few days ago in this spot where it was 91 km remaining range - a total of just over 100 km with 80% DOD.
It doesn't last long though. About 2 km later, after a substantial climb at 70 to 80 km/h, it is usually down to 72 km remaining. By the time I get to work it's around 77 km remaining (Range) after 15 km travelled (TRP). The trip home is always worse and I'm arriving home lately with 31 km travelled and about 54 km remaining range. The Vogue has a 12 kw/hr pack (20 AH at 600 VDC) and all dashboard calculations are performed assuming only 9.6 kw/hr (actually 16 AH) is available.
A note or two about comments - I really like getting them. I have to moderate what comments get published - currently I publish everything. You can leave me comments privately or publicly though. If you like, you can leave a comment and just mention that you don't want it published, "don't publish this John", and I won't.
To leave a comment just click on the "No comments" (or "'n' comments") at the bottom of any post.

I have purchased a new set of rear shock absorbers (new, old stock Monroe 12-0060 - yes eBay) and will hopefully get them installed during the Christmas to new year break - plus a review/refresh of all rear-end suspension rubber components
I'll also make some time to further investigate the vibration issue that is still present - less intrusive but still there.

I drove all the way up to the bistro entrance, passed a balcony about 1 meter off the ground were 3 or 4 guys were sitting having an ale or two (or three).
As William got out of the Vogue one of them called out to him "Is that a Humber". William just looked back over his shoulder and said "yes". As he walked away I rolled down my window and gave the standard speil "It's a 1965 Humber Vogue but it's a bit different". They just nodded - then I said "It's a battery powered car - electric". They nodded again. "See" I said and accelerated forward a couple of meters, "no noise - no petrol engine". They collectively dropped their jaws and I could see that that was the end of the discussion - so I drove off. I didn't see their faces but William told me later that they just looked - didn't talk - just looked as I drove away.
That's my fix for another week.

My new seat diaphragm arrived during the week so on Saturday (yesterday) I removed the drivers seat and checked out the old seat diaphragm.
Oh oh! The new one was too big. Not excessive but enough that it didn't support the foam. It appeared to be about 20mm larger.
Old diaphragm front-to-back hole-hole measurement.
I kind of spat the dummy at this point and considered giving up on the diaphragms and using the webbing I had ordered in case the diaphragm didn't work out.
Then I noticed that the clips that were supplied last time were larger than the standard Vogue ones. I had to use the Vogue ones to hold the aluminium pieces to the seat frame (that allowed me to use the smaller TR6 diaphragms).
The clips used last time were about 28mm to the inside of the hole. the Vogue ones were 20mm.
The new diaphragm didn't come with clips.
They were VERY difficult to bend so I think they'll stay bent.
Then I measured the hole-hole dimensions in the seat again and used suitably size clips. I hadn't bent them perfectly - they ranged from 19 to 22mm so I arranged them largest to smallest and selected appropriately.
The diaphragm took some getting in as I worked from the underside without removing any foam or fabric but once in, it fit nicely. About 10mm stretch in each direction. The previous one had 19 and 12mm stretch - maybe too much - the 19 was side to side where it tore.
The seat is back in the car . I forgot to take the "after" picture but it looks pretty much like when I originally did it except that the diaphragm covers slightly more of the foam - which is good.
