We are investigating the use of the BQ34Z100-G1 device for deep cycle automotive/marine applications.
These batteries are typically 6 cell, 12V lead acid, High current (over 500 CCA) (old technology) non-AGM batteries.
Typical applications may include 20-40 Amp constant drain for several hours (deep cycle). Or 100 to 400A short duration engine cranking followed by slow recharging. Predictability of drain on the battery would be inconsistent at best so I assume some parameters would not be reliable.
Questions:
1. Is the impedance tracking technology applicable to this application? If not, is there another recommended approach you might suggest using TI parts?
2. Can a general battery characterization (chemistry) profile be used for the application or does each battery type need to be specifically characterized/modeled ?Do you have any models of automobile or marine batteries that are available to date?
Any help would be greatly appreciated!
