Hi,
I currently have a project that involves a 12V lead acid battery pack (2 batteries, 100Ah each connected in parellel) that has a combined capacity of 200Ah. The particular lead acid type for this pack is a AGM type (Glass mat, valve regulated, 6 series cell), deep cycle.
I have downloaded bq evaluation software, ran a chemical update tool from TI to get the latest chemical IDs.
However, looking at the excel sheet provided, it seems that no lead acid batteries of the AGM variance have been characterized. Below is a snippet of it:
| Chemical ID | Known compatible cells | Comment | status, 0 if OK, 1 if NRND | |
| 0800 | Leoch: Valve Regulated 6s (7200 Ah) | 1 | ||
| 0801 | EnerSys: Cyclon DT (4500) | 1 | ||
| 0802 | Panasonic: R121R3P | 1 | ||
| 0803 | Panasonic: LC_P1220P, Enersys: Cyclone_D (2500mAh) | 0 | ||
| 0804 | Sonnenschien: A512 (10A) | 0 | ||
| 0805 | Exide: FX10_12XT9_8 (10Ah) | 0 | ||
| 0806 | Bazooka: HPT-150 (150Ah) | CONTACT TI BEFORE USING THIS ID | 0 | |
| 0807 | US.Battery: XTREME_Capacity (155Ah) | 0 |
Since chemical ID 0800- 0802 are not recommended for new designs (NDRD), I am not considering them.
As for the rest of the chemicals, the closest match is the Sonnenschien: A512 (10A), which is a deep cycle gel battery. The panasonic P1220P is meant for UPS applications and not for deep cycle discharge in my opinion.
I have heard of a mathcad program that will help the engineer to choose the closest chemical ID and I will go an attempt to do that.
I have two questions:
1) Is there any updated chemical ID library that has more batteries that are characterized? Any timeline of any newer version?
2) Why are chemical IDs 0800- 0802 flagged as NRND ?
I have searched the forums and most of the posts are related to the Litnium Ion battery chemistry.
