Chevy Volt Battery Documentation
Contents
Overview
We purchased a Chevy Volt Battery (Gen 1) for $999 from M&K Auto Parts in Orange City, Fl on November 6, 2017. This battery will be torn down to individual modules to be used for new Power Racing Series vehicles for the 2018 season. We are expecting to get seven 48v modules, and two 24v modules from the Volt battery. These modules are heavy (~50 pounds), but should have enough power to not require a battery swap for any race including the 90 minute endurance race.
The 48v modules will be 12s3p configuration.

Battery Management System
- Chevy Volt teardown: The battery pack This video has some great slides showing locations of components and how cells are grouped into packs and then grouped into modules and then detailed info on the BMS. Alternate recording, may have better audio

Charging PPPRS 48v Modules
We are unsure how we will charge. We've seen reference to splitting the pack in two electrically to charge as two 6s batteries, and we've also seen where people simply charge the entire pack with voltage monitoring. This is a BIG TODO.
