I have exhausted my parametric search and am looking to the expert TI community to know if the following requirements can be met with a modified or direct application of a TI part.
I need to create a charging station for the following 2 batteries (NOTE at present I do not have access to the battery manufacturer and am limited to the information below:)
PbAcid batteries
1. 8 cells in a string, cells wired in series 12V per cell = 96V 5.2Ah
2. 9 cells in a string, cells wired in series 12V per cell = 108V 8.5Ah
All of the charging ICs I see on TI are for 48V and lower. Is it possible one of them could be modified to work with the high voltage?
My Power source for charging the batteries is 115VAC.
Also I believe what I have gleaned so far from researching the different batteries is that Lead Acid usually charge with a constant voltage source.
They require a two-stage charging system - Fast Charge then transitioning to Float charge.....
Any feedback is appreciated!
