PROBLEM TO BE SOLVED: To suppress power required for a uniformizing process in a vehicular battery pack uniformizing system. SOLUTION: The vehicular battery pack uniformizing system 10 includes: a plurality of temperature sensors 14 for a battery pack; a plurality of voltage sensors 16 for electric cells for composing the battery pack; a uniformizing circuit 22 for implementing a uniformized discharge from the battery pack; and a control block 300. A uniformization processing instructing section 36 is provided in the control block 30, and determines whether a uniformization processing section 38 is instructed to implement the uniformization process based on a temperature fluctuation. The uniformization processing section 38 includes: a processing condition setting module 40 for setting a processing condition for implementing the uniformization processing for a limited target period or intermittently based on the temperature fluctuation; a voltage monitoring module 42 for monitoring a voltage of each electric cell; and a uniformizing circuit implementing module 44 for actually implementing the discharge in the uniformizing circuit 22.
