PROBLEM TO BE SOLVED: To provide a temperature adjustment device for an on-vehicle battery capable of maintaining a temperature of the battery within a desired temperature range while suppressing power consumption during parking.SOLUTION: The temperature adjustment device comprises: a temperature adjustment part 11 for heating or cooling an on-vehicle battery 2; a temperature adjustment control part 12 for controlling the operation of the temperature adjustment part 11; and an activation part 13 for activating the temperature adjustment control part 12 in predetermined timing while an electric vehicle 1 is parked. The activation part 13 includes: a relay 16 for switching connection of the temperature adjustment control part 12 and a power source 6 to ON or OFF; a transistor 17 which is provided within an activation circuit including the power source 6 and the relay 16; and a thermistor 18 which is provided within the activation circuit in such a manner that a current to flow from the power source to the transistor 17 is varied. When a temperature of the thermistor 18 exceeds a predetermined threshold value, the relay 16 is switched to ON.SELECTED DRAWING: Figure 2
