I just joined this forum. I live in Costa Rica and need some advice. I found a used Silverado hybrid battery and am searching for 2 days to see what the cells are inside the pack, and the ratings of these cells, including weight per cell..

I think these would make a sufficient pack for a lightweight motorcycle, but, no luck finding specs ? I could take the cells out and reconfigure them for a 72V pack, which I have experience in building from other cells.

I realize this is off topic for this forum, but, I'm stumped.

Can anyone here help with this info ?

Thanks, Harold

 

OK the GM truck uses the exact same chemistry/modules as newer Prius. Here is one on Ebay. Toyota uses 34 of these, GM uses 40 in a pack. If you look closely you may make out the six ( 6 ) cells in this module. Fully charged this single module is over 7V.

There is a little hose connection on each one for hydrogen venting. There is a little hole on top for a temperature sensor. The + and - terminals are about 5mm thread. The low voltage on one of these is just under 4.5 volts. If you pull lots of current under 4.5 volts you can damage it. If you charge it over 7.5- 8.0 volts, youi will shorten its life.

 

Ahh, heavy and not able to reconfigure to fit a lightweight moto frame.

Down here, we are over run with the India and China made 125's. They are lighter than the typical Japanese Motos, so, I need to find something I can disassemble and change the shape.

Thanks for the info, Hillbilly_Hybrid.

 

The batteries I would use are the "Refrigerator Pack" Lithium Ion like some of the Belt Alternator Starter BAS Malibu etc use. They are nick named Frige Pack because they are individual Lithium Ion rolled in round cans and stacked like soda cans in a box. But to get 72V you would need more than one pack. A coworker and I have discussed taking an old 175cc enduro bike and using the 15kW BAS machine on it. The battery, motor/generator, and inverter would still be larger and heavier than the original engine and transmission. But it would out run mopeds.

 

Went and did some searching for those "fridge packs" with no results. I did use different descriptions, by the way. Even tried the Chevy Malibu name and BAS phrase.

HOW do you find these things on the 'net ??

Thanks, Harold

 

Start here

Then some history on BAS technology.

Now if you can find a picture of the battery and the insides... my description might become clear.

 

New information WAS very helpful. I found battery manufacturer and total specs. NO internal cell photos, but, I already know how can cells are made.

Thank you VERY much for putting up with this old man. Computer stuff is beyond my mental limits.
