POWER FEED CONTROL DEVICE

摘要

Provided is a power feed control device that can reduce the number of voltage conversion means provided to a vehicle, reducing component costs. The power feed control device is equipped with: a voltage detection means (control unit (10)) that detects the output voltage of a battery (9) or an alternator (7); a status acquisition means (control unit (10)) that acquires the status of an engine (6); a voltage conversion means (20) that steps up and steps down the output voltage; a switching means (30) that switches the power feed to a plurality of in-vehicle apparatuses to either the output voltage or a voltage converted by the voltage conversion means (20); and a control means (control unit (10)) that outputs an instruction to switch the switching means (30) on the basis of the output voltage value and the status of the engine (6). The switching means (30) switches the power feed destination to a first in-vehicle apparatus group to which a voltage higher than V1 should be applied, and to an other second in-vehicle apparatus group. The control means is configured to output a step up command or a step down command to the voltage conversion means (20), and to output a command for switching between the first in-vehicle apparatus group and the second in-vehicle apparatus group to the switching means (30).
