A battery module is a key intermediate level structure in a battery system, usually consisting of multiple cells (single batteries) combined in series or parallel to provide higher voltage and capacity to meet the electrical energy requirements of a specific application. The main functions of a battery module include connecting cells, pooling current, collecting data, and securing and protecting cells.
