Industry jargon
Battery cells
Battery cells are the individual electrochemical units that store and release electrical energy inside an EV battery pack. Cells are connected electrically and mechanically to achieve the voltage, capacity and power required by the vehicle. EV cells are commonly manufactured in cylindrical, prismatic or pouch formats. The format describes the package shape rather than the battery chemistry. A battery pack can contain hundreds or thousands of cells, with sensors and a BMS used to keep operation within safe limits.
