What happens when a battery is fully charged?
Once the voltage achieves its maximum, charge cut-off voltage, the circuit switches to constant voltage charging mode. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage. When the batteries are fully charged, the charging current drops to 0.1C.
What is maximum charging current?
Maximum Charging current: It is the upper limit of how high of a current you can provide a battery and charge it while still being in the safe zone.This can change for different types of battery cells with different specification and even different manufacturers.
How does battery capacity affect charging current?
The larger the capacity of the battery, the higher the charge current is usually. Similarly, the higher the charging ratio, the higher the charging current and the shorter the charging time. For internal resistance, the greater the internal resistance, the lower the charging current.
