In practical terms, battery efficiency is the percentage of energy recovered from the battery after a full charge-discharge cycle. Thus, you can compute it by dividing the energy output by the energy input and multiplying your answer by 100. The discharge current and voltage combine to provide the energy output; that is their product.
The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].
Thus, you can compute it by dividing the energy output by the energy input and multiplying your answer by 100. The discharge current and voltage combine to provide the energy output; that is their product. The energy input is calculated as the product of charge current and voltage.
Definition: The energy storage capacity of the system (ESCsys) calculates the total amount of heat that can be absorbed during charging under nominal conditions. The energy is mainly stored in the material; however, some set-ups may contain components in contact with the material, which inevitably heat up, hence storing sensible heat.
The calculation focuses on the price of thermal energy and determines the cost range for TES to be economically competitive based on today’s energy prices.
