When encountering a new charging segment, the capacity-related features are extracted easily, and the trained model can be used to accurately estimate the capacity of the battery pack in a regular and continuous manner, which does not need to meet stringent requirements for the labeled capacity calculation method.
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
Herein, we present calculation methods for the specific energy (gravimetric) and energy density (volumetric) that are appropriate for different stages of battery development: (i) material exploration, (ii) electrode design, and (iii) cell level engineering.
