When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
Standard Charging: Using a standard charger that supplies a typical current (usually around 0.5C to 1C, where C is the battery’s capacity), it takes approximately 2 to 3 hours to charge a Li-ion cell from 0% to 100%. Fast Charging: Some modern chargers can supply higher currents (above 1C), reducing charging time to as little as 1 hour.
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
It is recommended to use the CCCV charging method for charging lithium iron phosphate battery packs, that is, constant current first and then constant voltage. The constant current recommendation is 0.3C. The constant voltage recommendation is 3.65V. Are LFP batteries and lithium-ion battery chargers the same?
On the other hand, undercharging can cause irreversible capacity loss, negatively impacting battery performance and life. Discharging below the minimum voltage threshold of a lithium battery must be avoided to keep the battery healthy and ensure optimal functionality. Using a certified charger to charge lithium battery packs must be considered.
Always use a charger specifically designed for li-ion cells. Avoid charging the battery in extremely hot or cold environments. Never leave the battery unattended while charging the li-ion cell. Charge the battery in a safe, non-flammable area to mitigate any potential risks. Part 4. How to discharge li-Ion cells?
