gas tank removed

I've driven the car to work a few times, realized I need a dc-dc converter otherwise I somehow managed to push my car along the street twice because I let my 12v die.

But the new news is the gas tank is out!,  which was a pain because the rear axle must be lowered.  But the non-pain part is it is possible to do this all without disconnecting any brake lines, whew that would be messy.

the dirty wall straight ahead is a vertical space where the rear passengers calves dangle down, so all the space behind that up to the thick metal in the foreground, is maybe 5 cu feet of space well protected and a nice candidate for batterys.

under side open space.  you can see the lumps where the rear passengers but used to sit.

if i cut something like the yellow outline, maybe I can end up with a large cavity of space to install a battery box.  This has lots of appeal.  Perhaps it will reveal better handling due to the big weights being between the axles instead of behind the rear.  also lower center of gravity *shrug*

yellow line for possible cutting

all gone!

THE gas tank

Licnese Plates!

I received my Colorado license plates today, along with a new little EV sticker they started in 2014 that is placed in the front window in order to park in spots where chargers exist (without getting a ticket).

I also purchased a Raspberry Pi with a 7" screen to install into my EV so it can show live data from the SolitonJr and the Orion BMS on the dash  (as well as watch movies and listen to music?), yet another project latching onto me!

test drives

Last week we did two 15 mile test drives.
This week I drove 27 miles round trip (without knowing if I'd make it home because I still don't have my e-meter setup) to my appointment with the Colorado Motor Vehicle Emissions Technical center, and they signed off a form DR2365 I needed to get my E type registration/title! I was pretty nervous, and some things went wrong before I arrived. 6 blocks away my car lost power due to my old rickety 12v battery dying off (still no dc/dc converter). So in the parking lot next to the one I 'rolled' into, there was a meineke auto shop which happily stocked and sold me a new charged battery ($120 later) and I installed it there in the beautiful Colorado winter sun, and arrived at my appointment three min early. (with the convertible top down!)
Things that went right?
1) I didn't get pulled over for my 3 month expired temp tag.
2) They signed the form needed.
3) I made it home without running out of electricity in my traction pack!
4) my new battery didn't die.
whew.


did get some video, will post soon.

major issue

Added another motor mount.  Let see if vibrations feel better now.

Somewhat major setback occured today when I went for another test drive (with 2 added motor mounts) to see how things felt and listen/watch for vibrations etc. As I was coming home I lost power to the drive train but the motor was still spinning up (but did not over-rev). And was definitely not spinning the trans in neutral either, just zero drag.

I looked through the open hole where the old starter motor used to mount on the trans, and could see that the coupler/clutchplate system was not spinning either, so I guess that means the splines are not stripped. My guess is the coupler slid down the shaft and off of the motor? I was not under heavy power, in fact I may have been coasting somewhat (as I crested a small hill).

I suppose the good news is, nothing sounded like it was breaking or tearing, there was no loud sounds, just lost power while going slow. still a bummer, as I will have to remove the motor at the very least. Possibly also the trans (hopefully not).

Other minor good news, the switches I put in the dash to power up the controller and the contactor are working, plus my rear lights are working. And it was nice I didn't have to tow it back, I was able to roll far (because I took the time to pump up the tires extra firm) small victories.

Other minor bad news I could not get her in reverse, my shifter linkage must not be quite right.

Better Motor Mounts

Motor mount improvements. My two goals were to 1. use ALL the existing/previous mounts in the compartment 2. have at least one mount connect to the large 1/2" bolt called "lift-eye" bolt in the center of the motor which is extremely strong.  The other mount on the back of the motor has two holes and is strong also, but it is two aluminum 5/16" screw holes, probably about the same as one 1/2" steel mount.  Plus the two spots are entirely separate functional parts of the motor, so I guess technically if the motor fell apart within itself both major pieces would remain connected to the frame? Seems like a remote bonus, hah.
Total of 4 mounts are in use now, two for motor and two for transmission. Since the motor and transmission are very secure together as one unit due to the plate and 5 bolts, the entire assembly has 4 mounts.

Front motor mount, seems flimsy by itself but it provides front to back strength, an area which the other new mount is weakest in. Has some rubber on the motor connecting bolt (eye-lift bolt)

This new motor mount is the strongest one and provides very strong side to side and up/down strength, has a small amount of rubber in there somewhere.

Bottom show of strongest mount.

This is an old shot of the wiring getting finished up from the controller to motor, the wood block is just to keep them from flopping around.

HV wires

A few days ago Jori and I added to the rear compartment wood setup to get things nice and sturdy with tie-downs.  It isn't final but will be good for test drives, etc.  Very importantly we reassembled the brake system which I inadvertantly took apart, this was a pending item of doom and now is back to normal.  I'm hoping I can do a test drive without the electric vacuum assist pump installed, but we shall see.  If I go down my drive way and have nothing but E brake then I'll have to put her in reverse!

Not all batteries are in at this point, just getting them in there roughly

running the HV wires up the side, same route as the large pack of wires that normally go from the dash to the rear lights

Heavy frame bar that provides a nice safety brace for the batteries (which will eventually be in a strong closed box)

And I did another long cut on the aluminum plate adapter up front.  Even though it's fully installed I was able to use the reciprocating saw to shave off another slice to make it fit better in there.  That cut is a pain but I'm getting better at it, and thinner shorter metal blades help too.

Today! was good (and still is) Firstly I drained the gas, still had 2 gallons so that was a smelly process.  I removed the filler system/inlet and all the wiring and sensors for the gas tank measurements, etc.  I loosened the tank itself but didn't get it all the way out, there must be some tricks to getting it out, mainly I just needed it empty so it doesn't pose a hazard and I cut all the cables and metal hoses out of the car having to do with fuel altogether.

Secondly I ran the big 2/0 gauge HV wires (welding cable) from the back to front, through the firewall which is tricky without removing the dash, but I think I have it worked out.

(last night I sewed some boxers using some light blue 50/50 cotton/linen fabric that I ordered up a few months ago, I really was too lazy to do laundry, so instead I spent 3 hours at the sewing machine? but they fell good! Jori got pics of me standing at the sewing machine with only a tee shirt on)

This cold season and the New Years trip to Vegas by car (gas powered Camry) slowed progress down some, but we are back at it.

A few weeks back I finally got things straightened out with my Elcon charger, the Orion BMS, the serial CANBUS interface between the two, and the bank of batteries.  Everything setup on my kitchen table with 50+ wires going all over the place, I got a full charge on my batteries with a real time visual on each battery as they balanced, etc.  A full charge is nice so I can do a test drive without yet installing the BMS or Charger into the car.

While my parents were in town over Christmas my Mom helped me build up the trunk area with wood for supporting the batteries.  It's nice there is a very thick and tall heavy duty steel support directly behind the rear seats that provides a nice safe way to keep batteries separate from people in the case of an auto accident.  We also brewed up 5 gallons of stout which is now in the bottling stage. yummy!  (pictures coming)
