Translations:Lithium-ion battery/2/en

Lithium-ion batteries are composed of many small cells that are wired in series and parallel to achieve a desired nominal voltage. These cells are very sensitive to over-charging and therefore require a battery management system (BMS) to ensure proper battery charging. Improper charging can not only irreparably damage the batteries but can also lead to a thermal run-a-way event with NMC batteries in which the temperature of a battery can no longer be controlled and rises to the point that equipment is damaged, or a fire is started.
