I have been wandering about the TI website, and youtube video channel, trying to wrap my head around battery management concepts, and I have come so far. 

We need a battery fuel gauge evaluation module, that should be programmable. I have been through the charger selection tool, and narrowed down a few products. I just some community feedback and validation of my choice here.

What we need it to do is : 

1.  Charge a single-cell Li-Ion battery. 

2.  Measure the charging-discharging current

3.  Measure the charging-discharging voltage. 

4.  Allow programmatic control of all settable parameters. 

5.  Maybe also measure temperature. 

Requirement 4 is mentioned as some of the user's guide that I read, didnt detail the I2C interface and I am confused whether they can be used without the EV2300/2400 adapters, as I wont need them, since I would be updating the parameters through my code and not the Battery management studio. 

Now, to the winning contenders, (and this is not a complete list):

1.  BQ78Z100 : This appears at the top of the list, and seems most advanced. Just not sure, if it fulfills requirement 4 stated above. 

2.  BQ-27742-G1: This does say in the description that  it is programmable. 

3.  BQ27GDK000EVM : This is by-far the funkiest looking and most confusing of the options. It looks power-packed, but I am not sure, if it is programmable and will work for us. 

So, to summarise, we need a battery fuel gauge eval board, that we can program, to periodically set charging voltage etc. and that in turn gives us the battery voltage and current etc. with high-accuracy. Additional features are welcome. Most advanced boards are preferred.
