When charging and discharging lithium-ion batteries, the current is an important factor to consider. The current flowing into the battery during the charging process determines how quickly the battery charges. A higher current means a faster charge time, while a lower current means a slower charge time.
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.
Lithium-ion batteries operate differently. They charge under a constant current and switch to a continuous voltage later in the charging cycle. The charging process reduces the current as the battery reaches its full capacity to prevent overcharging.
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
When using and charging a lithium-ion battery, it’s critical to keep the current in mind because it can affect the battery’s performance and lifespan.
