Other Parts Discussed in Thread: BQSTUDIO
Hello sir,
Urgent !! I have setup for testing fuel gauge basically to educate as my project requirement (for future use) and for battery. I am using BQ27742-G1 , EVM2400 , BQstudio and battery specification is (Tenergy 3.7v 1400mAh Li-ion).
First simply i check voltage, avgcurrent and SOC. SOC did not update as my voltage change in charge and discharge mode. So i go through process of chem id(rel-dis-rel) for new chem id. And after i got new chem id i just upload to fuel gauge and SOC level start to change in charge and discharge mode correctly.
I take one battery having voltage around 3730mV and connect load at load side which draw around (avg voltage : - 250 to - 300mA by connecting resister). Then fuel gauge suddenly indicates voltage around 2980mV and SOC: 0% because terminate voltage is 3000mV, so this is right operation. But if i disconnect load voltage level increase around 3720mV, But fuel gauge does not wakeup (stable in shutdown mode) and it should resume by itself after detecting higher voltage than terminate voltage but it does not. so please give me suggestion what should i do ?? and if i reattach battery in socket with no load connected it work fine . Indiacte SOC and other parameter as well.
for my application i want device shutdown if voltage is less than 3600mV and maximum charging capacity till battery 4200mV. and it should indicate soc : 0% at 3600mV and soc : 100% at 4200mV, for this where should i need to make change in data memory. ? and do i need to go throgh learning cycle process for this problem or this is actually real characteristic of fuel gauge.
Thanking you,
Regards
