To achieve cost reduction and space saving, in a coolant warmup control device of an electric vehicle.SOLUTION: A coolant warmup control device 1 of an electric vehicle 10 which is driven by supplying power from a battery to a traveling motor via an inverter 13 includes a warmup circuit 2 in which a coolant 3 which is formed so as to be heat-exchangeable with a warmup object 14 having a warmup function circulates, and an active discharge resistor 6 arranged in a high-voltage circuit 4 in the inverter 13, and used for discharging an electric charge of the high-voltage circuit 4 when the electric vehicle 10 is stopped. Also, the coolant warmup control device 1 includes a heat-exchanging part 7 which can exchange heat between the coolant 3 circulating in the warmup circuit 2 and the active discharge resistor 6, and a warmup control part 8 for raising a temperature of the coolant 3 up to a desired temperature by controlling a power amount which is consumed by the active discharge resistor 6, and controlling a heat exchange amount between the coolant 3 in the heat exchanger part 7 and the active discharge resistor 6.SELECTED DRAWING: Figure 2
