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 batteries necessitate a charging algorithm that upholds a constant current constant voltage (CCCV) during the charging process. In other words, a Li-Ion battery should be charged by a fixed current level, usually 1 to 1.5 amperes, until it hits its concluding voltage. Lithium is one of the most important metal resources that we have today.
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
Discover the optimal charging voltages for lithium batteries: Bulk/absorb = 14.2V–14.6V, Float = 13.6V or lower. Avoid equalization (or set it to 14.4V if necessary) and temperature compensation. Absorption time: about 20 minutes per battery. Ensure safe and efficient charging to master battery care and optimize performance.
During the bulk charging phase, lithium batteries need a controlled charge at a specific voltage level. This ensures equal charging across cells, preventing imbalance issues within the battery pack.
For most li-ion cells, the standard maximum charging voltage is 4.2 volts per cell. As charging progresses, the voltage gradually increases until it reaches this maximum limit. At this point, charging should stop to prevent overcharging, which can severely damage the battery and pose safety risks. Part 2. Understanding discharging li-ion cells 1.
