My Dusty 71 GMCe Electruck

now every battery pack has it's pros and cons, be it a Tesla pack, a Nissan Leaf, or this BMW 530e, and this one is no different, one of the downsides of it is these unobtanium proprietary high voltage cables, it is a real challenge to reconfigure the standard pack layout whilst utilizing only the stock high voltage cables

some like this one joins two cell modules very smartly.... (we like, we approve)

here is one BMW 530e battery pack (Embedded Fun Fact: which consists of six cell modules, unlike the 330e which only has five) reconfigured in The Stack Formation, unfortunately we are unable to complete this arrangement because we are one cable short, technically we have the cable but it is just too short to join Cell Module #2 to Cell Module #3

I'm a Simple Man, I see a gap... and I fill it!

[Gregski]

yes we did run out of gas... (no literally)


but we recovered, and one side's done

[Gregski]

and onto the other side, having the frame rails level now is a total game changer


man I love a clean canvas

[Gregski]

alright, let's load 'em up proper

[Gregski]

now I currently only have one pack installed here, but hopefully you'll get the idea how this design is meant to hold two of them, six cell modules on top and anther six upside down

this will yield 18.2 kWh

so at 3.5 miles per kWh we guestimate a range of 63.7 miles

keep in mind this is just a start, I can install more batteries under the bed

Excellent progress. I'll have to stop by to check this out in person next time I drive that way.

Thank you, Indeed! bring your wire wheel, this purple paint aint gonna fall off by itself, ha ha

[Gregski]

so time to make a List for Phase I as I plan on doing or should I say NOT doing some stuff in this Phase that may be a bit controversial

PHASE I PROGRESS REPORT

1. Mount Lexus transmotor - ✔
2. Install modified Lexus drive shaft - ✔
3. Mount transmission fluid pump controller
4. Mount Lexus inverter - ✔
5. Mount Honda CRV brake booster - ✔
6. Install Toyota Prius power steering column - not happy with this install (my job, not the part)
7. Install first BMW 530e battery pack - ✔
8. Lay down the Controller aka VCU on the floor inside the cab
9. Install modified BMW 530e pre charge circuit aka "Safety Box"
10. Install Chevy Volt first gen DC-DC converter
11. Install BMW E46 throttle pedal
12. Install B&M transmission floor shifter
13. Install Tesla Model S water pump

Not happening in Phase I

1. Lock input shaft in the Lexus transmotor*
2. Install onboard battery charger**
3. Install Battery Management System aka BMS***
4. Install customized digital gauges
5. Install second BMW 530e battery pack

the Controversial Section (we can thumb wrestle over these items if you like - by appointment only, ha ha)

* Input Shaft, I want to dyno test the truck with only MG2 powering the rear wheels to see how much horse power it actually puts out in real life

** no Charger, this is the first of the radical ideas, why do we need a battery charger mounted on board permanently, isn't that the equivalent of driving around with your very own gasoline/petrol pump, can you imagine pulling up to SHELL or Chevron with your own pump mounted in the back of your truck?

*** no BMS, eventually I plan on getting SimpBMS but it is just so expensive here in the States, I think they want $650 for the hardware

[Gregski]

another day another mock up, and I'm loving how it's turning out

[Gregski]

as much as I love this BMW 530e hybrid battery pack, it's Achille's heel has got to be the proprietary high voltage terminals, which call for the unobtanium plugs and wires, here I am trying to figure out how to use only the stock amount of high voltage cables to rewire it flat instead of two cell modules stacked on top like in the original implementation

[Gregski]

no I didn't just spend 4 hours drilling two holes in the most unreachable of places, who in their right mind designed these silly frame extensions?!?!

[Gregski]

tell me you're done with Fab without telling me you're done with Fab

[Gregski]

finally... no more Purple (sorry Prince, R.I.P.)

Looks like you've dealt with your violet tendencies...

Had to get just one more in before I let it go, haha.

[Gregski]

the transmission crossmember also got sum red luv in our outdoor free range organic make shift paint booth

Bonus Points for clever use of not only exhaust pipes but exhaust U clamps, not like we're going to be needing them again

well played, you're not just blowing smoke that's fer sure

[yuccales]

I'm thinking that inverter is a prime candidate for a fake Delco.
