Hi
When we use your company's BQ4050 for portable energy storage projects, the low-temperature discharge SOC will jump significantly, and the CEDV parameters calculated using the CEDV algorithm fuel meter are not suitable. Because according to the report, the SOC accuracy at room temperature and high temperature will be greatly affected by using CEDV parameters, so in order to not affect the SOC at room temperature and high temperature, our company's current SOC algorithm does not enable the CEDV function. However, this causes the SOC to jump sharply at low temperatures, so does your company have any solutions or opinions on the problem of large jumps in low-temperature discharge SOC of the BQ4050 solution? I hope you can take the time to help us analyze and solve this problem. A problem that has been bothering us! (Please see the attachment for the data of running CEDV parameters, the configuration of BQ4050 and the low-temperature discharge data of our products).
