Tool/software:
Our solar- and battery-powered product uses the BQ25672 charger IC. We recently discovered that when the power source (a solar panel) provides limited power, the battery charges slowly, and eventually the safety timer activates, capping the battery at around 60%. After the safety timer is triggered, the battery will no longer charge, even if the solar panel continues to supply power.
We currently address this issue by toggling the CE pin every 12 hours, which resets the safety timer.
I have a few questions regarding this approach:
- Do you have any concerns or feedback about this solution?
- Is this solution suitable for production use?
-
When toggling the CE pin (from low to high, then back to low), will a fully charged battery be recharged? If so, are there any concerns about keeping the battery close to 100% charge frequently? For example, could this negatively impact battery lifespan?
Looking forward to your response.
