Other Parts Discussed in Thread: GPCRB,
Dears,
Customer are using BQ27520-G4 in low temp such as -20°C, so they use gpcrb to optimize the low temp performance.You can check the materials in attached.lowtemp.rarlowtemp-report.zip
Below are their concerns,
1. In below picture, there are 2 Qmax cell, they want to know which Qmax is Qmax in low temp.
2. What is the function of T rise and T Time constant?
3. In the gpcrb output T rise is 0.75, but when write 0.75 to BQ27520-G1, it will display format is not right, customer must write a integer, so they write 1 rather then 0.75. This operation is right?
4. In GPC_report.txt, “Ra0_ch, mOhm : 122 This firmware is not explicitly supporting Ra0_ch, FCC drop could occur at low temperatures if used”,what does it mean? Whether it means that BQ27540-G4 don't support low temp?
Best Regards,
Rock Su
