Provided is a battery temperature control device configured so as to automatically heat a battery (1) not being used by using a battery-driven heater (2), so that the battery does not freeze at minimum battery power consumption. The battery temperature control device predicts, from the combination of a battery temperature (Tbat) and the outside air temperature (Tatm), the time that the battery temperature (Tbat) is likely to be less than a first set temperature (Tbat1) , while the battery temperature (Tbat) is at least the first set temperature (Tbat1) at which there is no risk of freezing (step S13), sets said time as the next controller startup time (?t) (step S14), and when this time (?t) has passed determines whether or not the temperature has decreased to Tbat<Tbat1 in step S13 by the control program wakeup indicated in the drawing, and battery drives the heater when this battery temperature reduction has occurred, to heat the battery (1) (step S19). |
