My Dusty 71 GMCe Electruck

and for those on the edge of your seats screaming, WHAT, you plan on charging those batteries using that measly 120 volt power cord that will take forever

OK, let's build a 240 volt washer and dryer cord for it as well, jeez

[Gregski]

and if we want to power up all three modules

[Gregski]

OR we can step it up to an Anderson SB50 connector like we did with the 120 volt one like so

and yes this is all still just for TESTING

[Gregski]

yes I will go full on J1772 socket power cord for the final build

[Gregski]

so here I was dinking around with 120 volt single power module charging

remember that red Wifi card on our open source logic board, well that's what the laptop is for it is talking to the charger using Wifi so that we can configure it and see how the charging is going, pretty cool stuffing

[Gregski]

and here I'm trying 120 volt charging using all three power modules

YES, the wife INSISTED I do this in the comfort of our fine dinning room, so who was I to refuse her wishes

My wife wanted to change the hardwoods in the house we bought in March, they had litterally just been refinished like 3 days before we made an offer on it.. she's since re changed her mind.

But the topic at hand, pretty dang neat! I gotta admit I've been kind of stubborn/ignorant to EV stuff. I work for a public utility fleet and have been doing a lot of research lately into possible options for our fleet and I see there is definitely a use for it, and hot rodding is hot rodding!

I can appreciate that, and the shift has happened multiple times throughout history

horse drawn carriage => to steam car (around 1850s)

steam cars => gasoline powered engines (cause you know sitting behind 30 gallons of hot steam was dangerous, lol, so let's put 15 gallons of gasoline behind our seat)

gasoline powered cars => electric cars (it's inevitable)

Loving this build. Most of it is way over my head but very interesting. Near where I work is a Tesla model 3 with paper plates stillthat went off the road and has been sitting there for about six months. I don’t have any desire to start scrapping it yet though��

thanks, and buy it and flip it for 3x what you pay for it when you part it out, the rear wheel drive unit aka motor/inverter combo is worth big bucks, the subframe it mounts to adds even more value, the batteries (which I assume are near 100% capacity) are super desirable as is the onboard charger, hewk buy it and sell it for 2x as a whole

The Tesla Model 3 is the world's number 1 selling 100% electric car, they surpassed the Nissan Leaf already!

looks like Tanner doesn't want me to sell Dusty's old seats on Craigslist

Nice work! That SB50 connector looks like what my kids powerwheels battery uses to charge.

thanks, and that's cool, the red one is an SB120 and I pick them based on the fattest wire gauge I can shove in them, so

SB50: 6-16 AWG

SB120: 1-6 AWG

Remember that the smaller the AWG (gauge) number the fatter the actual wire, so it's bass ackwards.

spit ballin' some battery pack formations

this is the Upside-Down Cake design

[Gregski]

then we stack the second layer on top, this one right side up, planning on using some T aluminum and L aluminum angle brackets in between the six modules

[layinrocker65]

Down the line, how hard would it be to add more batteries?

that question is on point as I am about to head out to pick up a second battery pack just like this one

let me start off by saying that there are two options

Option 1 - will allow me to run two of them in parallel meaning we add up the amp hours (but the voltage stays the same aka 350 volts) so I will essentially double my capacity from 9.1 kWh to 18.2 kWh to increase my range (this will put me in the Chevy Volt battery size range)

and I can keep adding battery packs until I literally run out of room on the truck

Option 2 - BMW makes a newer pack using more bettter battery technology that is exactly precisely the same physical size but they increased the capacity from 9.1 kWh to 12 so I can simply replace mine with the newer one, it will bolt right up to where this one went and hook right up with the existing connectors, (two of these would add up to 24 kWhs and would put me in the Nissan Leaf battery size range) hope that helps

[Gregski]

so I'm just one cable short to link them all although I show two short leads extra here, I am using the #6 main positive lead as one of the links (to join modules 2 and 3)

Sacramento to Los Angeles yesterday there and back in under 13 hours, got my second 2018 BMW 530e battery pack, paid $1,100 for this one (paid $900 for my first one, so $1,000 per pack average, for those of you good with maths, ha ha)

on the conservative side with zero testing in my truck at minimum one pack is good for 20 miles of range (now before you judge, this is a very conservative guestimate, and ten years ago studies have shown Americans on the average drive 40 miles per day, a similar study done recently revealed that number has dropped to only 25 miles per day, I realize that may not be you, but we are talking about averages, ha ha)

I am super happy

Fun Facts: (WoW)

• Wifes job is only 1.1 miles away from our house
• Grocery store is only 1.2 miles away from my house
• Target is only 2 miles away [and there's a friggen battery charger in their parking lot]
• Home Depot is 2.7 miles away
• Credit Union aka our bank is 2.8 miles away

Google Map yours just out of curiosity?
