To carry out battery temperature control, battery input/output control, and cell module clogging diagnostics while keeping the number of temperature sensors installed to a minimum A battery pack cooling system in which cell modules (31), (32), (33) configured from a plurality of cell cans (31a) are set in an internal space of a battery pack case (1) so as to have a cooling passage, thereby cooling the cell modules (31), (32), (33) by cooling air flowing in the cooling passage. In this battery pack cooling system, the cooling passage is configured comprising a cooling air inlet passage (51), a cooling air exhaust passage (71), and a plurality of cooling branch passages (61), (62), (63) disposed to link the cooling air inlet passage (51) and the cooling air exhaust passage (71) in parallel. The cell modules (31), (32), (33) are installed respectively in the plurality of cooling branch passages (61), (62), (63). Second thermistors (12L), (12h) are respectively installed in an upstream position and a downstream position of one second cell module (32) of the plurality of cell modules (31), (32), (33)
