The invention relates to an power storage unit (5), including a housing (21) and a battery pack (6) accommodated in said housing (21), as well as an air passageway (7) passing through said housing (21) such as to be able to guide an air flow for cooling said battery pack (6), the air flow being capable of producing sound waves propagating in said air passageway (7), said storage unit also comprising a resonator (23, 43) extending into said air passageway (7) such as to be able to attenuate the sound waves, said resonator (23, 43) being provided in said housing (21). Limiting the propagation of noise disturbances in the cooling circuit of the electric batteries while maintaining compact dimensions is thus possible.
