Battery cell

Meaning in automotive, with examples

nounCommon term

In automotive, battery cell means: The smallest electrochemical unit of a battery. Many cells are connected into modules and packs; the main formats are cylindrical, prismatic and pouch cells.

In Turkish: batarya hücresi, hücre, pil hücresi

How it is used

Battery engineers talk about cell chemistry (such as NMC or LFP), cell voltage, cell balancing and cell suppliers. A typical lithium-ion cell has a nominal voltage of about 3.2 to 3.7 V, depending on chemistry.

Example sentences

  1. One battery cell in module 6 is 50 mV lower than the others.

  2. The new model switches to LFP battery cells for the standard-range version.

Common collocations

  • cell chemistry
  • cell voltage
  • cell balancing
  • prismatic cell
  • pouch cell
  • battery packThe large high-voltage battery that stores energy for an electric or hybrid vehicle. It is made of many cells grouped into modules, with cooling and control electronics in one housing.
  • BMSShort for battery management system: the electronics that monitor the voltage, current and temperature of the cells, keep them balanced and protect the battery from overcharging, deep discharge and overheating.
  • thermal runawayA dangerous chain reaction in a lithium-ion cell in which rising temperature causes reactions that release even more heat, which can lead to fire, toxic gases and spread to neighboring cells.
  • state of chargeHow full a battery is at a given moment, shown as a percentage of its usable capacity. The battery management system estimates it continuously.
