Owe to their high electrical energy density, lithium-ion batteries are the most employed technologies in electrified vehicles, whose market share is growing very fast. As a matter of fact, their thermal management is of crucial importance to keep the operating temperature within an appropriate range, as this might greatly affect performance and durability of such devices. Heat generation during cyclic charge and discharge processes, occurring during a vehicle mission, may cause critical temperature variations and, therefore, a suitable thermal management is indispensable. This is particularly true for fuel cell hybrid electric vehicles, where the battery undergoes more severe thermal stresses than in battery electric vehicles, due to higher operating C-rates.
