Oh well……into the breach, I’m now committed to electric

So, after a long wait, it’s gone from this to…….

…..this forlorn wreck. 

After my friendly garage had stripped it – to the skin!!!!, we eventually agreed on a ‘one-stop’ body shop in Stockport.  It was needed to stop any problems between trades and to let one shop do the lot. The NEW estimate accepted was mid between £1500 and £4500 (both of which needed three trades to finish). Timing will be between 6 weeks and 2 months. During the work I will be able to take progress photo’s and further research the electrification. 

Two potential avenues – 1/ ‘Classic Electrification’ and 2/ ‘The London Electric Car Co’. The former will “help” with parts and advice, but the latter will install the lot.  I’m also researching the individual controllers for one 10hp DC or a three phase reversible motor. I haven’t got any measurements on the motor case, but the technical data is promising (the prices are looking good to).

One motor on EBAY is 10hp, 2500 rpm, 36 Amps.  Another motor is 7.5Kw, 10 hp, three phase, 2800 rpm (perfect) and is only £285.  The motor controllers are not expensive (£85 – £150) and seemingly will work on the existing accelerator pedal.   One controller has stage power (a bit like gears) Older readers may have heard a milk float click into three stages of drive. 

I already have two new ‘Deep Cycle’ 130 amp/hr lead/acid batteries (which you may know are designed to provide 13 amps over 10 hours) Working out the power needed, I think 4 batteries would provide 52amps for 10 hours. 

When the running gear was removed, a weigh bridge VAN load total (with all the gear aboard) was 1700 kilos. Removing it all and re-weighing, I seem to have removed 200 Kilos (440 Lbs) 31.5 Stone……thats 2 humans!!!!  

 

 

Supposedly……the Baby Austin could propel  “4 adults” to 55 mph!!! (ha ha ha)  but in 1933 I bet people were lighter than me. So should we say 2 of us would cover the loss of metal.  To my calculations that leaves 4 adults equivalent for batteries.  I am not going to re-fit the back seating area, I’m reserving that area for batteries. There are other places available UNDER the floor pan between the chassis rails. I recon we can do this with cheaper deep cycle Lead Acid batteries, but if we cannot, we will have to look towards more modern Lithium Iron – which are megabucks (these are fitted in Tesla cars).

I’m also removing the horrible sliding roof (but remember, I’m not destroying reversibility). This cutout will be used for two 100watt solar panels. I have three in stock, two are ‘flexible’ which may be needed looking at the curved roof line.  I haven’t shown the body shop yet……….

That is far as the project has reached.

    Had you thought about the lynch motor (guess two back-to-back would give sufficient output for decent speed), these are DC but can provide regenerative braking, which I think is difficult to achieve unless AC. A lead-acid battery is more environmentally-friendly, it can be re-cycled, lithium-ion batteries use precious minerals and cannot be recycled (at the moment?) so are somewhat un-environmentally-friendly…

      The electrics have been finalised. Re-generative braking is now part of the drive and I’m using 2nd hand Mitsubishi Lithium batteries – 42 in the main pack and 14 in a reserve pack**. The Lighter weight batteries are easier to distribute and I’m also using a replica petrol tank to house the reserve pack** to keep weight further back (don’t forget, the steel tank and the 5 gallons weighed-in almost as much as butteries). I’m looking for YEARS of useful battery life and by the time 5-6 years have passed, ‘batteries’ will be part of our fuel language. Thanks for commenting.
