The voltages that factor into the determination of the battery voltage can be stated in relation to how they detract from the ideal voltage. This voltage is defined as the difference between , and , . The first set of voltages that detract from the equilibrium voltage are known as ohmic voltage drops.
Voltage: The battery voltage is the voltage difference between the anode and cathode. Different battery chemistries have different rated voltages; for example, Li-ion cells have a rated voltage of 3.7V, while alkaline cells have a rated voltage of about 1.5V. Higher voltages result in higher capacity and output power.
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
A normal alkaline cell, for instance, has a nominal voltage of 1.5 volts, while a typical lithium-ion cell has a nominal voltage of 3.7 volts. It is crucial to understand that a battery's nominal voltage is used to classify and compare batteries, whereas the actual voltage of a battery changes during the course of its discharge cycle.
First, the battery voltage that the model is capturing and our system is measuring is seen in Figure A.1 to be the difference in potential between the surfaces of the negative and positive electrodes. The voltages that factor into the determination of the battery voltage can be stated in relation to how they detract from the ideal voltage.
The standard operating voltage of a battery is indicated by a reference value known as nominal voltage. It is a standardized measurement that illustrates the voltage range in which a battery typically functions.

Characterize Battery Cell for Electric Vehicles
You can estimate the ohmic resistance R o from the sudden voltage change at the start of a discharge or a charge pulse (for example V1 to V2 or V5 to V6). To estimate the R i and τ i parameters, you can use the short voltage relaxation immediately after the discharge (V4 - V5) or the charge (V8 - V9) pulse. You can extract more time constants from the longer voltage …
