CONTROL DEVICE, GROUP OF CONTROL DEVICES, AND POWER STORAGE DEVICE

摘要

Total power consumption obtained by totaling the power consumption of each of a plurality of heaters across the plurality of heaters is stabilized while the temperature of a module battery is brought near a target temperature. The required power that must be supplied to the heaters in order to bring the temperature to the target temperature is updated for each of a plurality of temperature control units at each of a plurality of first update opportunities that arrive repeatedly at a relatively low frequency. The required power is maintained at a constant level until the subsequently arriving first update opportunity. A heater selected so that the power difference between the total required power and the total consumed power falls within a reference is updated at a plurality of second update opportunities that arrive repeatedly at a relatively high frequency. The selected heater is maintained at a constant level until the subsequently arriving second update opportunity. The selected heater is a heater that is enabled to be turned on, or a heater that is turned on.
