I have a 1997 Chevy S10E, (GM built, not a conversion). It was designed with the Panasonic Lead Acids but I'd like to go with Lithium. There are several issues that I have to deal with.
1. The Battery Pack Control Module, (BPCM), Has to see "12" volt signals from all 26 batteries in series. (About 353 volts fully charged). So I can't just assemble a 353 volt lithium pack to replace them.
I do OK with mechanical and electrical issues but I need to know if anyone out there can get into this computer, (The BPCM), and modify or eliminate the 12 volt signal requirements? Similar to "Flashing" a computer in a car to change performance.
This truck, produced in 97 and 98, had Lead Acids and Nickle Metal batteries which require different charging algorithms. There is a program available to flash between the 2 packs using a laptop and the a Tech 2 analyzer, which I have, so I'm thinking it's possible.
My next problem would be charging. But one issue at a time.
Thanks,
Kevin
