A configuration is provided in which the suppression method can be made different for each type of load when the power consumption of the load is to be suppressed. The on-vehicle power control system (1) includes a first load control unit (3) and a power control device (10). In the power control apparatus (10), each of the switch units (21, 22, 23, 24, 25, 26) is configured to turn on each of the second conductive paths (31, 32, 33, 34, 35, 36). Switch to the de-energized state. The second load control unit (12) predetermines the type of each of the switch units (21, 22, 23, 24, 25, 26), and sets the power suppression instruction specifying the control method for each type to the first load When received from the control unit (3), the switch unit (21, 22, 23, 24, 25, 26) is controlled for each type based on the control method specified for each type according to the power suppression instruction. |
