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.
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
In this article, the impact of different fast-charging profiles on the charge/discharge performance and cycling characteristics of commercial lithium-ion batteries has been investigated. It has been shown that, as expected, that the charging profile has an influence on battery performance and its dynamic characteristic.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
The specific charging strategy is to charge to 4.2 V at 1C (2.8 A) and then switch to constant voltage charging. After the current reached the corresponding cut-off current in the constant voltage stage, it rests for 30 min and then discharges to 2.5 V at 1C (2.8 A) current.
The experimental results show that the six typical charging strategies result in better battery performance, in terms of charging and discharging capacity, charging time, charging temperature rise, and energy efficiency.
