Abstract:
1. A vehicle load control device comprising: a battery that supplies power to an electrical load of the vehicle; a battery sensor that detects a consumption state of the battery; a control unit that cuts off power supply to the electrical load when the consumption state of the battery reaches a predetermined state; and a timer; wherein: the electrical load includes a first electrical load to which power supply and cut off under the control of an operator are possible, and a second electrical load to which power supply and cut off under the control of the operator are prohibited; the control unit performs a first control for detecting a consumption state of the battery at a relatively short first time interval, in a case where a consumption amount of the battery after an engine stops is greater than or equal to a predetermined value; the timer is operable to measure a duration of the first control, and regardless of the consumption state of the battery, the control unit cuts off the power supply to the first electrical load and ends the first control when the measured duration reaches a predetermined time; the control unit performs a second control for detecting a consumption state of the battery at a relatively long second time interval, in a case where the consumption amount of the battery after the engine stops is less than the predetermined value, the control unit operable to cut off the power supply to the second electrical load in the second control; and the control unit cuts off power supply to the electrical load depending on the consumption state of the battery detected by the battery sensor.
