The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery’s state of charge (SoC) – how much energy is left in the battery. Here’s a simplified SoC chart for a typical lithium-ion battery:
The plots show the voltage and discharge current for a battery with a response time of 30 s. Select to have the block determine the parameters in the settings based on the values specified for the parameters in the settings.
Maximum theoretical capacity, , when a discontinuity occurs in the battery voltage, in Ah. This value is generally equal to 105% of the rated capacity. Minimum allowable battery voltage, in V. This voltage represents the end of the discharge characteristics. At the cut-off voltage, the battery is fully discharged.
Power: A battery’s power rating determines how much power it can deliver to the connected loads. It is the summation of the battery’s voltage and the allowed maximum discharge current of the battery.
Capacity: The entire energy in a battery is measured here, and it is usually expressed in ampere-hours (Ah). It provides information on how much charge the battery can deliver at a particular discharge rate. Energy Density and Power Density: The quantity of energy stored per unit of mass or volume is measured by the energy density (Wh/kg or Wh/L).
These criteria are essential for a number of reasons: Selection and Sizing: Engineers can select the best battery for a certain application by knowing the parameters and calculating the size and number of batteries required to match the specifications.
Vector and Scalar
A scalar quantity describes only magnitude. Scalar quantities are everywhere, from the speed of a moving object to the energy of a nuclear power plant. On the other hand, vector quantities help to determine the direction or orientation of physical phenomena, processes or events. Many quantities, such as displacements, forces and velocity, will ...
