Bob's EV · 1 May 06
A few days ago I posted a link to a story about Bob Hurst and the EV he made during the 1970’s oil crisis.
As chance would have it his son ran across another part of this site a few days later and sent an email suggesting I post something about his Dad’s story.
We exchanged emails and James sent a couple photos for our viewing pleasure.
Bob’s EV uses a 1957 Citroen as the donor chassis. If you follow the link you’ll see that it was quite the looker in its day. It originally sported a six cylinder engine and his and her machine guns…oh, wait, wrong movie.
This is the main “engine” compartment. James thinks that the electric motor is a GE but no word on where Bob originally got it, or what it used to power. The blower fan cools the motor and cycles some of the heat into the cabin during the winter.
As for some of the more exotic parts, according to the article:
“When I saw the thing (X-ray machine), I went out of my mind, all those diodes and relays,” he said.
The diodes and relays would have cost him hundreds of dollars if he had bought them new, but the junkyard owner sold them for $2.
Click to see larger versions and let me know which components you can identify! I can spot a monster fuse there towards the top (or is it a 1970’s diode?) and what looks like a couple wire wound power resistors.
His son James says that it originally had twelve, twelve volt batteries along with a six volt battery to power the accessories. His been putting in long hours on the weekends to make a new frame and new floors. The article also mentions that the wheels and much of the rubber and hosing needed to be replaced after almost thirty years parked in the woods.
But even after all of that time the electric motor “fired” right up the first time.
For more details be sure to read the article.
Thanks to James and Bob for a glimpse back into a really early EV!
p.s. if you come across a schematic, James, we’d love to see it.
UPDATE 5/1/06: Jim sent a bunch of images and I picked out the following. Also, be sure to check out the Channel 4 TV news story featuring Bob and his EV.

An EV action shot with what looks like the TV reporter along for a ride…
30 year old batteries looking a little worse for wear but not all that bad considering. I like the “tube and wire” routing of the power cables.
The tires also need to be replaced. It looks like the old tire on the right has some partially inflated tube sticking out.
The floor in some places had rusted out. This is one of the sections that Jim and his dad cut out, beefed up, and replaced the flooring in.
Here’s the newly fabricated flooring before being welded into place.
And here’s what it looks like, along with new battery racks, put back in the EV. Nice work!
A slightly different perspective on the main power electronics (well, some of them). The big (pink?) cylinder looking things in the metal plates with braided cable coming out of them are diodes. There’s an automotive relay and a power resistor on the right hand side.
