Just a Little Short On One End

While I was perusing the website I noticed that for some reason I got it in my head that I would only need 7 cells on each side in the back. I can only fit 27 cells in the front rack. A quick calculation and I come up with 41 Batteries total. So we (Willie the Welder and I) are putting 8 batteries in the back on the drivers side and 7 on the passenger side giving us a total of 15 batteries in the back approx 180lbs plus the 130lbs of motor and the 40 or so lbs of Controller and the 9 lbs DC to DC converter approx 350lbs in the back and 324lbs in the front. Let me see…
Thats 684 lbs say 700 lbs which includes the motor, controller, dc to dc converter, charger and all of the batteries and battery boxes. the body with the windows and accessories weighs in at 600lbs and I dont know what a 74 VW chassis weighs so I am up to 1300lbs not including the weight of the chassis. Does anyone out there know the weight of a 74 VW chassis? The weight of the Lead acid gel batteries I am replacing was 840 lbs and only 1/3rd the energy. I think this car will weigh in at approx 2100lbs fully energized.

These photos show the passenger side battery box with the batteries in it (not final) to show how they will fit in the box. Obviously they are not ready to be hooked up. Note the pos and neg terminal placement…not correct. The second pic shows the bat box placement in relationship with the controller.


Operation Cleanup

This is the DMOC and wire harness… notice anything different? Where are all the wires? If you follow from the DMOC to the back wall you will see a black cable going into the wall through a gland nut. The new location of the DMOC (controller) has advantages. I moved the relay board into the car on the back wall. Actually I have lost the board and opted for a scheme which allows me to place the relay’s closer to where they will be used.

Re Wire with Heat

Ok guys I finally got the heater installed properly and the plenum is in place. The wire harness is installed and anchored in several places. The wires are all labeled and I even found the schematic. I guess I didn’t give it away after all. So onward and upward. I ordered a harness weather kit and when It arrives I will make new connectors for the modified headlight and directional light system. Today I received my PowerLab 6 in the mail and will start bottom balancing my cells while I am working on the wiring. Today of course, I am at work so the balancing act will have to wait until later.

And so I plan… Three battery boxes built for easy access and durability as well as strength. Here is my plan. A lexan box with an aluminum frame riveted to the outside of it. The frame will be built from Aluminum L brackets. My neighbor Willie can weld aluminum so the brackets will be welded. With this setup you will be able to see the batteries and they will be protected. The design is light weight Aesthetically pleasing and durable (have you ever tried to break Lexan?)
I see three arrays of batteries. Two with eight cells each on either side of the motor and one big 26 cell module up front. the most pos and most neg terminals in the pack will be at the very back where they can be easily connected to the controller.
Then there is the speedometer, I have been looking at GPS speedometers and think I have found one suitable for my needs. I found it at the Speedhut
It is very cool and does not require anything additional to work. It comes with everything.
Next on the list is my interior… But that is another story
Keep On Pluggin
