What determines the operating voltage of a battery pack?
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
How many cells are in an electric car battery pack?
Electric car battery packs generally contain between 200 to 800 individual cells. The most common type of cell used in electric vehicles is the lithium-ion cell. The specific number depends on several factors, including the battery’s design, capacity, and the vehicle’s overall performance requirements.
What is the difference between a battery cell and a pack?
A battery cell is a battery’s basic unit, whereas a battery module is a collection of battery cells. A pack, on the other hand, consists of one or more modules as well as any other components required for operation, such as enclosure, connectors, and control circuitry. The following comparison chart demonstrates this in greater detail:
