My Dusty 71 GMCe Electruck

nothin' 50 feet and a gallon of bondo won't hide

[Gregski]

but you aint here for shaddy body work and rust repair is you?

since I only replace the blade on this saw once a decade it only took me 9 hours to figure out [again] how to do it, YES IT IS A REVERSE THREAD BOLT, thank you Delta for not putting a sticker on the saw stating that, makes for much more fun

[Gregski]

like a hot knife through buttah

you can check out this setup in action here, the pause in the cut is do to me stopping to take a peak at my phone to make sure it was recording

just spit ballin' the BMW 530e battery placement

[Gregski]

so I am sourcing these batteries from a 2018 BMW 530e hybrid vehicle and a Battery Pack consists of six of these Cell Modules (a cell module being a brick the size of a regular car battery, except packing nearly 60 volts each) so the entire pack is roughly 360 volts

I plan on running three of these packs in parallel giving me still only 360 volts but adding up the range, my goal being 100 miles (all needing much testing and experimentation)

[Gregski]

like Sardines

[Gregski]

and here is the entire first six pack mocked up, I think it needs to go forward sum towards the bow more but for now I just laid them on the flatest part of the frame [and yes flatest is a word, I just made it a word]

[Gregski]

so each one of those Battery Packs (consisting of six Cell Modules) is 9.1 kW and I plan on running at least two of them in the front and one or two more under the cab and or the bed of the truck

general rule based on my experience with a Nissan Leaf for three years says you can expect roughly 3 miles per killer watt so 9.1 times 3 equals a range of 27.3 miles per pack

now I get that by dividing my Leaf range of 84 miles by it's 24 kW battery pack which gives me 3.5 mile average per killer watt and because my vehicle may be heavier and less aero dynamic I round that down to 3 miles instead of 3.5, kapish

and we can thumb wrestle over this till the cows come home, but I can also tell you that, that Leaf has seen a range of as high at 106 miles on the same battery pack so there's that, it all depends on your driving 'habbits" as they say

[Gregski]

second verse, same as the first

[Dieselwrencher]

Those fit in there pretty nicely. So you're thinking you will have roughly 160 miles of range with those 6 batteries?

no all six of those equal just one battery pack and I hope to get 27 miles out of a single pack

I plan on having at least three of those battery packs so a total of 18 of those "batteries" twelve up front and another six under the bed

Fun project! More value as of lately

thanks mate, indeed, I could not wait to get crackin' on this project

[Gregski]

Costco Jack & Craigslist Jill what could possibly go wrong

Oh no it's too big! how many times have I heard that before [don't nobody answer that!]

[Gregski]

someone once said you haven't wrenched until you made or modified yer own tool, am I right fellas

I once volunteered at a motor cycle shop for Big Al the man who sold me this truck, we quick become friends, and I asked him once why he cut his ratchets down to stubbies and he said: "cause I got tired of snappin' them bolts"

that's some street credit right there you feel me Young Blods?

[Gregski]

so let me get this straight, now we needs a jack to put the transmotor on the jack and we needs another jack to lift the rig up on ramps to git that trans on this jack under the jacked up rig??? follow all that? ha ha

this sounds like one of them two things we likes like chocolate and steak just not together there deals

I recon all them hernias from bench pressing those 850 lbs transmissions [I'm looking at you Muncie SM465] was a worth it

shout out if you know what a Granny Low SM465 feels like, ha ha

[Gregski]

so here we go again, another one man slow dance

[8man]

Trying to play catch up, and it's tough for an old guy. The batteries looked good inside the frame rail. Can you run them toward the tail end further too? Looked like there was some frame back there to put another row. If I remember your work from before, you've already considered that.

Also, like the jack conversion. Beats getting a buddy and laying on your backs to try and muscle that thing in!!! Did that with a Torqueflight 727 when I was much younger.

Whoa, so one battery pack only gets 27 miles? Did I miss how the Leaf got close to 106 miles from its pack? Seems like a lot of batteries for 80ish miles. Are the new 2020 and newer batteries more efficient or just more of them? Some adds for the current electric vehicles claim 300 or more miles per charge. how do they accomplish this range?

this battery is from a hybrid called a BMW 530e the Nissan Leaf battery is from a 100% electric vehicle

this one is only 9 kWh the leaf one is 24 kWh

just last night I received some good news from a fellow EV Converter running the exact same battery pack and transmotor and he confirmed we can now calculate 3.25 miles per kWh if not 3.5 (son on par with the Leaf) I was being conservative at 3 miles per kWh

the BMW pack is much much more bang for physical space the Leaf battery pack is huge

Okay that is good news, more miles the per pack the better. But you will need three of the BMW packs correct? Which should equal the Leaf pack size? But at total 27KWH (9x3), does it work that way?

yes you got it, it will be a bit bigger capacity wise 27.3 kWh vs 24 kWh of the leaf

and that's just Phase I, cause BMW makes a newer pack that is 12 kWh instead of the 9.1 yet it is exactly the same physical size, so in Phase two I plan to upgrade to three of those for a total of 36 kWh so maybe a 125 mile range with that one, we shall see

[Gregski]

just increased my chances of injury by 400%

making a bell housing block off plate since there will no longer be a Lexus V6 internal combustion engine in front of this hybrid transmission or transmotor as I call it, because there are two electric motors inside of it

[Gregski]

took a bit of back and forth, and for some odd reason Lexus decided to use two different sizes of bolts on this bell housing, the red circles mark the larger ones which in SAE or American standard sizes equate closer to a 1/2" and the smaller ones are roughly 7/16s

it may take another round of nip and tucking to get the plate to match that weird shape it happens to be

[Gregski]

next it was time to work on the Ninja star, this is the clutch plate coupler I cut out of the original clutch plate thingie, I will be using it to lock out the input shaft of the transmission, doing so will force the front electric motor to spin the output shaft assisting the second larger electric motor, win win
