Key terms and definitions. Battery pack: A battery pack is a collection of individual batteries that are connected together to provide a higher voltage or capacity than a single battery could provide. Cell: A cell is the basic unit of a battery. It consists of two electrodes (anode and cathode) that are separated by an electrolyte. When the cell is connected to a

Battery thermal management (BTM) offers a possible solution to address such challenges by using thermoelectric devices; known as Peltier coolers or TECs [16, 17].TECs transfer heat using the Peltier effect [18, 19] and have advantages such as compactness, lightweight, and ease of integration [20].They can be placed near battery cells, reducing
A Reduced-Order Lumped Model for Li-Ion Battery Packs
The current term, I, can be taken directly from the experimental data or, with some artifices, expressed in terms of current density. The current density for a full-cell can be calculated using the so-called NTGK model (Newman, Tiedemann, Gu, and Kim 2,29,30).The current density can also be stated as a function of temperature to include the Seebeck effect.
