I have a new electric truck getting shipped to me.

Fun. That has potential.

Yeah...
Maybe Will would do a collab with me on it?
Fun fun fun.

Oh wait, I forgot where we were. You'll have to use 65s/5BazillionP of 18650's and a REALLY kick-ass BMS.

10s 24v Rackmount batteries?

What the hell was the factory battery bank like??!!??

Factory was a pair of 75S LFP valence cell packs.
I have two banks of A123cell packs that came from a different truck, but should use the same protocol... I hope.

It will be a lot of work. First you will have to stack the panels high enough to fit the number you would need, secure them, but also make it so you can quickly deploy them in an empty parking lot each day. I would recommend building some variable angle 2x4s so you can minimize your down time between deliveries. You got this!

I am thinking a pair of harbor freight solar panels should be enough to charge it…

Let’s theorize how long the charge times will be.

With the space on the top of the box.... anything from HF will be a waste.

20,000 AA cells in a 100p200s pack will run the truck at full 48kW power for 20-30 minutes, which is enough to get across town and buy more batteries.

I advise getting them in bulk. A pallet of 48,960 AA alkaline cells will be a touch over $7,000, and should give you well over an hour of driving, with one stop to change batteries in the middle. I'm pretty sure your truck can hold at least 10 pallets, so a full 8 hour shift of driving is easily possible, with an average cost of under $7,000 per hour and NO carbon emissions WHATSOEVER! Obviously this is far better than any old gas vehicle, and the cost is surely worth it. Disposing of the batteries is a minor detail, and inconsequential given the benefits of a non-carbon emitting truck.

But they've got kickstands already! What more do you need?

But wait!
I have 3 sets... that oughta work...

 

[Symbioquine]

I understand a fresnel lens can increase the solar collection… how many lenses will it take? Can I stack them?

You'll need even more if you want to charge with moon light!

“Top Speed Set At 50 MPH. To Save Juice”. Ha. That would be a long day in the right lane in Atlanta.

The charger interface is 7.4KW 3phase 208 input... sounds like a sloooow charger.

Approx 22.8A per phase.

Is yours a first-generation model with an induction motor or second-generation with a permanent-magnet motor?

My brother and I have always wanted to build an EV RV. That just might work.

I saw a truck like that on eBay probably 12+ months ago. Wonder how many of those were made?

 

[Bluedog225]

On a rational expense basis, how far could you drive on $10,000 of charged batteries? Balance of system aside.

[Bluedog225]

Interesting. Thanks!

100miles

What's the charging miles per hour?

 

[Shale MacGregor]

What's the charging miles per hour?

Not sure what Uber's rate is for larger vehicles like that, probably can charge a fair amount.

I mean battery charging.

How many miles of charge per hour of charging?
