BQ34110: BQ34110

Part Number: BQ34110
Other Parts Discussed in Thread: GPCCEDV

Hello:

Here's the issue description:

No charge or discharge operations were performed.

Until 08/17 SOC stays at 100%. During this time regular device resets have been performed. This means, PSU might have switched to power down mode on a regular base.

Last device startup has been logged at 08\17 07:37. From that point in time the device was not switched off.

On 08\19  SOC dropped to 90%.

Do you have any suggestion on how to deal with this issue? Thank you in advance.

  • Hello Wen,

    Did you run the GPCCEDV tool to find the CEDV parameters for the gauge? CEDV based gauges rely heavily on coulomb counting, so the gauge did see current flowing during that time to drop the SOC.

    Are you suspecting the SOC is inaccurate? Can you share your pack specifications and the GPCCEDV report?

    Sincerely,

    Wyatt Keller
