The charging profile for lithium batteries primarily consists of two phases: constant current (CC) and constant voltage (CV). During the CC phase, the battery receives a steady current until it reaches a pre-defined voltage limit, typically around 4.2 volts per cell. The CV phase then engages, where the voltage remains constant while the current gradually decreases until the battery reaches its full capacity. Temperature monitoring is essential during these phases since lithium batteries can be sensitive to heat, which can lead to thermal runaway if uncontrolled. Charge termination occurs when the current drops to a specific level, signaling that the battery is fully charged. For example, a study by Battery University in 2021 highlighted that incorrect charging methods could lead to severe battery damage.

2. Charging Profiles for Lead Acid Batteries:
The charging profile of lead acid batteries comprises several distinct phases. The bulk charge phase involves charging the battery at a constant current until it reaches around 70-80% state of charge. Following this is the absorption charge phase, which maintains a constant voltage while allowing the current to taper off, effectively bringing the battery to near full capacity. The float charge phase then keeps the battery at a reduced voltage, preventing discharge during idle times. Some lead acid batteries also undergo equalization—an intentional overcharge to balance cell voltages. The U.S. Department of Energy recommends specific charging profiles to enhance lead acid battery longevity. A recent study by Zhang et al. (2023) emphasized that adhering to manufacturer-recommended charging profiles can significantly improve battery efficiency and lifespan.
