The disclosure is directed to techniques for a thermostat to determine the air temperature of a room based on measurements of temperatures sensors located inside a housing of the thermostat. Because the thermostat for an evaporative cooler operates at line voltage and controls current flowing to the evaporative cooler, the magnitude of current flowing through the thermostat may vary from nearly zero, when the thermostat is in the powered-off state, to a current on the order of several amps. The variation in current causes a variation in temperature inside the housing of the thermostat. The techniques of this disclosure compensate for changes the internal housing temperature caused by changes in operating mode. The compensation allows the temperature sensors inside the thermostat housing to determine the air temperature of the room in which the thermostat is located, without regard for the operating mode of the evaporative cooler system.

A battery system includes a battery module, thermistor, and ECU. The thermistor detects the temperature of a first area in the battery module. The ECU calculates the estimated temperature of a second area having a higher temperature than the first area in the battery module, by adding a temperature correction amount to a detected value of the thermistor. The ECU is configured to set the temperature correction amount according to a time differential value of the detected value. Then, the ECU sets the temperature correction amount such that the rate of increase of the estimated temperature of the second area does not exceed a predetermined rate that is larger than zero.
