battery charging
If the controller changes to trickle charging at 14.2V, and the trickle charge is <= LFP''s self discharge rate, would it be safe to use it to charge a 14.6V battery that has no low current disconnect? Does the fact that the controller implements trickle charging mean that it was designed for a lithium chemistry other than LFP? $endgroup$

$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

What happens when a battery is fully charged?
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
What happens if you charge a lithium ion battery below voltage?
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
What happens at the end of charging a battery?
At the end of charging, when the voltage is almost maximum, we limit the current so that the BMS does not dissipate too much energy. UPD. The voltmeter will likely show the average of the charging voltage and the current battery voltage. Thank you so much for the answers! If I get you right.
How does the voltage and current change during charging a lithium-ion battery?
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
When does a lithium ion battery charge end?
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
How does state of charge affect battery charging current limit?
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC.
