The lithium battery voltage experiences significant fluctuations during charge and discharge, influenced by various factors, including the differences in nominal voltage among different materials, voltage fluctuations during charge and discharge processes, and the impact of voltage changes on battery performance.
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
Constant Voltage Charging Stage: When the lithium battery voltage reaches 4.2V, charging enters a constant voltage state, maintaining this voltage while the current gradually decreases over time until charging is complete. When discharging, the trend of voltage change in lithium-ion batteries is the opposite of charging.
These changes are closely related to the battery’s internal chemical reactions and physical characteristics. In the initial phase of charging, the lithium battery voltage is usually low, and as the internal chemical reactions of the battery gradually reach equilibrium, the voltage rises.
Using this method, the presented study statistically evaluates how experimentally determined parameters of commercial 18650 nickel-rich/SiC lithium-ion cells influence the voltage drift within a 168s20p battery pack throughout its lifetime.
The voltage of a lithium-ion battery system always fluctuates during charging or discharging. If you see the voltage during charge or discharge cycles, you will notice that the voltage remains constant initially and then varies over time. In the discharge cycle, initially, the voltage will be 4.2V.
