BQ40Z60EVM - Get continuous power supply

Other Parts Discussed in Thread: EV2400, BQSTUDIO

I want to get continusous power supply for my load. I use a 12V DC Fan connect to VSYS and PGND to test.

use 3S lion battery and short 4P and 4N.

use a 19V,3A power supply on VAC and PGND.

connect EV2400 on SMB bus.

use defalut firmware,download from web site  (sluc598.zip).

after the connections , push the wake-up button, the bqstudio look ok. battery voltage,AC power are ok. bus the fan don't work .

I can use the COMMAND button control the discharge and charge.

Now,I want to a cotinusous power supply. 

1.only battery,then battery discharge. VSYS output.

2.VAC=19V,then battery can be charged automatic. if battery is full,charge stop automatic.

3.only VAC=19V.then VSYS output.

so,What should I do?

The default firmware is ok? I need the learn cycle? need the calibration?  

Thanks!!!
