Battery capacity or Energy capacity is the ability of a battery to deliver a certain amount of power over a while. It is measured in kilowatt-hours (product of voltage and ampere-hours). It determines the energy available to the motor and other elements.
In Eq. (27), the authors constructed the battery pack multilayer difference model and used adaptive extended Kalman filter to achieve capacity estimation for both cells and battery pack. The results show that the errors of the cell capacity are within 3 % and the average error of the battery pack capacity is 3.02 %.
It can be seen that the capacity estimation errors of both battery packs are within 1 %, indicating that on the basis of single-cell capacity estimation, the proposed method can further effectively estimate the available capacity of the whole battery pack.

Battery capacity is measured in two different metrics: Gross or Total Capacity. It is the total amount of energy theoretically held by the battery. Net or Usable Capacity. This is the energy that a car can actually draw on to propel itself. The difference is created by automakers to prevent the full charge and discharge of the battery.
Battery capacity refers to the maximum amount of energy that can be stored in a battery, typically measured in ampere-hours (Ah), milliampere-hours (mAh), or watt-hours (Wh). It is crucial because it determines how long a device can operate before needing a recharge. A higher capacity means longer usage times for devices like smartphones, laptops, or electric …
