The general terminology for battery unit hierarchy used in this document are as follows:
Cell - The Simplest and Smallest Battery Unit, No Control Or Monitoring
Module - A Collection of Cells Contained Within Factory Packaging and Including A Voltage and Temperature Measurement Board
Battery Pack - A Complete System Containing Multiple Modules, an Overall Supervisory Management System, and a Thermal Management System
Vehicle System - A Complete System That Consists of Multiple Battery Packs To Meet the Overall Vehicle Power Needs. This Includes a Master Controller.

Data sheet of single cell
Calculations:
cell voltage is 3.2V
cell current rating is 80 Ah
Design battery pack power 18kwh
if the 10 cells are in series then
voltage of series string is 3.2* 50=160V
so current = 18000/160V= 112.5
number of cells connected in parallel= 112.5/80=1.4 apporimtely 2
so total battery pack power with the above calculations are
Electric circuit:
If the cells are prismatic cells then the mechanical structure as follows
Mechanical pack.
