However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
Battery voltage refers to the electric potential difference between the positive and negative terminal. A battery pack's voltage is the sum of the individual cell voltages. For example, a battery pack containing six 1.5 V cells would be rated at 9 V.
When there is a capacity difference between individual cells, the battery pack’s performance is determined by the individual cells with the smallest capacity. When there is a polarization difference between individual cells, the battery pack’s performance is determined by the single cell with the largest polarization degree. 3.1.2.
A battery pack is a portable energy storage device that consists of multiple individual batteries or cells connected together to provide electrical power. These battery cells are typically rechargeable and are used to power a wide range of electronic devices, from smartphones and laptops to electric vehicles and power tools.
The capacity of a battery pack refers to the amount of electrical charge it can store, typically measured in ampere-hours (Ah) or milliampere-hours (mAh). This parameter directly influences the runtime of a device or system powered by the battery pack.
