Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
Running the battery with a constant current load, I observed the output voltage gradually rise over time. The cause was fact that the internal power dissipation produced a temperature rise in the pack, and the output voltage rises (all else being equal) with temperature.
unfortunately it says nothing about ESR of batteries which is why Voltage decreases with rising current. In general, the answer to your your question is, "yes". As other answers have pointed out, a battery has an effective resistance. This is, in part, do to the fact that the internal structure has an intrinsic resistance.
Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps. Advantages and Disadvantages of Series Connections
A battery can be defined by the gradient of its power vs. current graph. This is what battery voltage means - the power a battery liberates when it supplies one ampere of current.
The first, and perhaps most important, relationship between current, voltage, and resistance is called Ohm''s Law, discovered by Georg Simon Ohm and published in his 1827 paper, The Galvanic Circuit Investigated Mathematically.
