Estimation of State of Charge for Lithium-Ion EV Battery Packs According to the application, a lot of cells are often connected in series to create a battery line with the necessary voltage
Single lithium polymer (Li-Po) cells typically have a nominal voltage of 3.7 volts. When the voltage of this type of cell is charged to 4.2 volts, it is considered fully charged. During the battery discharge process, when the voltage drops to 3.27 volts, the battery is considered fully discharged.
During charging, lithium-ion batteries exhibit distinct voltage characteristics that reflect their electrochemical processes. The charging cycle typically follows a constant current-constant voltage (CC-CV) protocol. Initially, the battery voltage rises steadily as current flows into the cell.
The difference of inconsistency for lithium-ion battery pack equalization is determined based on the uniform charging cell voltage curves hypothesis. Stability of the sampling voltage interval and convergence of equalization are analyzed experimentally.
Different types of lithium batteries, like lithium cobalt oxide, lithium iron phosphate, and lithium polymer, though all part of the lithium family, have vastly different voltage curves and electrochemical characteristics.
During the charging and discharging process of lithium polymer (Li-Po) batteries, the relationship between voltage and SOC (State of Charge) exhibits clear nonlinear characteristics. Especially when the battery is approaching full charge or discharge, the voltage changes more rapidly.
Therefore, you should pay attention to the brand from which you are purchasing your batteries. If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference.
