Full battery pack with 2x24 modules, 20 kWh
The Lithium-ion battery is composed of elementary units, called modules, stacked (number and layout) according to capacity needs and architecture constraints.
Each module contains 4 battery cells.
Each module contains 4 battery cells, in which take place reversible electrochemical reactions, allowing to produce electrical current (battery in discharge) or to store energy (battery in charge).
flow of electrons = electrical current
During the battery is in discharge, the Lithium ions move from the anode to the cathode. This reaction causes a flow of electrons (electrical current) in the supply circuit. When the battery is in charge, the opposite reaction happens.
