Hoovie's Garage: Bought a Prius with a dead battery
Re: Hoovie's Garage: Bought a Prius with a dead battery
I was being serious. If these batteries are 1200, it seems like we could figure out something cooler than a Prius for them.
Re: Hoovie's Garage: Bought a Prius with a dead battery
Do you have to give them a core? I think you might.
And also these batteries may not be that great from an energy storage per dollar standpoint. Have to look into that.

This is not clear to me:
Our List Price:
$1,382.25
with FREE Shipping
Core Price [?]: $875.00
Here's How the Core Charge works:
A "Core Charge" is like the deposit you might pay for a bottle or can of soda.
The part you are purchasing is recyclable.
When the used part from your vehicle is returned to us, the charge is refunded to you.
You must return the old part in the box the new one came in.
To return your "Core" or old part please submit a support ticket and we will send you instructions.
The Customer pays return shipping on the "Core" or old part return
Sounds like it is 1382 without a core.

Re: Hoovie's Garage: Bought a Prius with a dead battery
How a core and core charge works is this:
- You pay $1382.25 + $875
- They send you a refurbished battery pack
- You send your old pack to them
- They refund you $875
So if you don't have a core to send, you're out $2257.25.
What this implies about their operation is this:
- They can buy a used battery pack for somewhere around $875 and therefore that's what yours is worth to them
- They take their ~$875 battery pack, combine it with good cells from other battery packs and end up with a good pack to sell
- They sell it for $1382.25 out of which comes: Shipping, the time to create a new, good pack, and some amount of profit
This all makes sense to me. But at $2250 I doubt this is the way to go.
Oh that is a Dorman, not the other people from Hoovie's video. Well I think what I said is still roughly correct though I would have expected Dorman to use new batteries in which case the $875 buys the packaging skeleton to actually house the cells, I guess.
The more important thing is what I described is how core charges work on replacement parts. In car land, it is fairly common for a new part to have no core charge (it's new, what would the core be for) and a reman to have a core charge (they "rebuild" or "repair" or whatever their process is). So if you don't send a core, they have nothing to rebuild or repair which is why there's a charge for that.

Re: Hoovie's Garage: Bought a Prius with a dead battery
Yeah. I was afraid of that. 2250 is high for anything we would try to make and resell for any kind of profit.
I was thinking that we could get a junk motorcycle, strip the gas tank (or not?), engine, exhaust etc., and add the battery and motor.
Motorcycles can be bought for 1 to 2K in decent shape.
Total parts would be something like
battery + motor + motorcycle + battery management module from Prius
2250 + 3000 (est.) + 1500 + ??? = between 6 and 7.5K???
Would still need the throttle stuff
How much would someone realistically pay for one of these when gas isn't really a big deal for motorcycles? I mean, from what I hear from people who have motorcycles, they aren't super reliable. This would be pretty solid for reliability I would think.

Re: Hoovie's Garage: Bought a Prius with a dead battery
So who does EV motorcycles, what are their offerings and what do they cost?
Re: Hoovie's Garage: Bought a Prius with a dead battery
Battery weight: somewhere in the 100 lb range.
Oh and: https://priuschat.com/threads/battery-dimensions.78813/
Then, what is the range of motorcycle engine weights (different cylinder arrangements, air vs water cooled), plus the gas tank?
I think the engines can be fairly light but a heavier water cooled bike has more weight to remove.
My sense is something more in the cruiser range vs a sport bike would be the right candidate.
The gas tank empty is probably pretty light, say, 10 lbs? And gas is ~7 lbs/gal and say it holds 5 gallons. So 35 lbs of gas plus 10 lbs of tank so 45 lbs there.
Which translates to 0.77" by 4" x 11.2".04-09 Prius NiMH module dimensions are 19.6x106x285 in millimeters. There are 6 cells per module and 28 modules per battery. All in series.

How much do electric motors weigh? And the controller?I'm interested in recycling a used prius battery as a power source for an electric motorcycle. I can't find the dimensions of the battery pack anywhere on google though. Can someone who owns one give me a rough estimate?

Re: Hoovie's Garage: Bought a Prius with a dead battery
I forgot an important one: total energy capacity of this generation Prius battery is 1.31 kWh. Say you'd access 85-90% of that. So 1.179 kWh. With ~100 lbs of battery.
E10 gasoline stores 32.78 kWh per gallon. With 7 lbs of gas plus some portion of tank weight to store 1 gallon. You can see where this is going.
https://en.wikipedia.org/wiki/Gasoline_ ... equivalent
Let's say the gasoline engine and total powertrain is 25% efficient. 5 gallons holds 40.975 kWh of effective propulsion energy.
If a Prius battery holds 1.179 kWh, even if it was 100% efficient, that is 2.9% the range compared to having a 5 gallon tank. Let's say 5 gallons is big and it's more like 2.5. That's 20.4875 kWh, which is 5.8% the range.
NiMH batteries are not what you want. Furthermore, the Prius uses a 67hp motor. I'm sure you could push the batteries harder (higher discharge rate) so the horsepower is in the range of fun on something light. But if you start with a heavier bike for weight/packaging, that is not good.
Again, with a Prius battery, my very informal assessment is you will have crap range and performance that is really only decent at very low speeds (which is where gas motorcycles are already at their strongest and don't need MORE low end torque).

Re: Hoovie's Garage: Bought a Prius with a dead battery
To put another spin on the Prius battery energy storage, that is the equivalent electricity as my 4000W generator running at 50% load for 35 minutes. During that time it would have consumed somewhere in the range of 0.2 gallons which takes, what, 15 seconds to replenish? How long does a Prius battery take to recharge? If you charge at 1C, which is an extremely high rate of charge and would need to be very carefully temp monitored and controlled (and probably not realistic) that would take...1.5 hours.
