The ALLithium® battery follows a modular concept. This means that the cells, as the smallest unit of the battery, always form a composite of multiple cells in a protected casing, known as a module. This module is controlled by a central management unit called the Battery Management System (BMS). Factors such as voltage, current, temperature, state of charge, and short circuits are continuously monitored at the battery, module, and cell levels.
Through this monitoring and control, it is ensured that the battery performance always stays within a predetermined range, and the battery is shut down if it exceeds this range. Additionally, the modules used in the ALLithium® battery are tested according to criteria described in the United Nations transportation regulations (UN38.3). Passing these tests requires that potentially hazardous situations in battery behavior are eliminated through multi-layered, sometimes redundant safety systems.
