Part Number: BQ2050 Other Parts Discussed in Thread: BQ34Z100 I am using an MSP430 controller to communicate with the battery guage IC (bq2050). The bq2050 has a single line DQ bus communication to transmit the internal parameters of the battery. The…
Part Number: BQ2050 Hi,
We need to find out the remaining capacity of the battery by communicating to the BQ2050 chip ( we know that its quite old chip, but the battery we are using is based on this).
We would like to know what is the correct way to find…
Other Parts Discussed in Thread: BQ2050 Hi,
I am using bq2050 in my project to display battery capacity. My battery size is 3200mah.
I have connected 0.1uf capacitor to RBI pin which doesnt discharge on removal of battery. So we discharge it via external…
Part Number: BQEVSW Other Parts Discussed in Thread: BQ34Z950 , BQ2050 , BQ2954 I'm using bq34z950 gauge. In EVSW I have read the default parameter and imported the deafult .gg file. In .gg I have made changes according to my battery pack configuration.…
Can you do HDQ communication and check if Charge bit is actually getting set and does NACL & NACH registers increment or decrement during charging or discharging respectively.And also check if your LMD got programmed properly as per your calculations…
Hi Manikandan
Discharge your battery fully and check if NACL & NACH has become zero and also check if your LMD has programmed properly.
Then Charge battery to full now NACH should be equal to LMD and NACL should be zero , if this happens then bq should…
Other Parts Discussed in Thread: BQ2050 Hello,
I am using bq2050 to monitor a Li-Ion battery with 11.1V & 3200mAh capacity.
As LMD is the true & measured battery capacity; shall I use the NACH & NACL data or (100*NAC data)/LMD data to show the battery…
Other Parts Discussed in Thread: BQ2050 Hello,
I am studying the appnote of BQ2050: http://www.ti.com/lit/an/slua021/slua021.pdf . The VCC of the BQ2050 is derived from Bat+ terminal. Battery is of supplying 12V, how can BQ2050 survive as its operating voltage…
Other Parts Discussed in Thread: BQ2050 Hello,
I'm using the BQ2050 in a system with a solar panel. I noticed that passing from discharging to charging phase, the NACL register sets the value to 1, while NACH doesn't change.
Is this a normal…
Other Parts Discussed in Thread: BQ2050 The bq2050 has internal temperature sensor and in our application will be some distance from the battery. How much error will be introduced if the temperature measurements is significantly different from the battery…
