Impedance Track Battery Charging Question

$

0

Hello,

I have a question about charging the batteries for the first step of the bqEasy "5. Cycle" process.  I am using a 2s1p cell with two 4.2V 4400mAh batteries.

1) Should I charge the batteries while connected to the bq20z65EVM while the Impedance track is "Initialized" (QEN is High)

2) How should I charge the batteries? Will the bq20z65EVM automatically cell balance at this stage?  I see that my options are:

A) Connect 8.4V @ Charge Current to the 1N and 2P terminal to charge the batteries in series.

B) Connect 8.4V @ Charge Current to the Pack+ and Pack- Terminals and open the CHGFET.  I believe that this will charge the batteries in series and not perform cell balancing.

C) Connect 4.2V @ Charge Current to the 1N and 1P terminal as well as another 4.2V @ Charge Current to the 1P and 2P terminals to charge the batteries individually.

D) It does not matter charge them however I would like.

 

 

Any help from an App Eng or anyone who has gone through this Cycle process with good results would be greatly appreciated.
