Title:
POWER SUPPLY CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2017030509
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress a battery life from deteriorating.SOLUTION: A power supply control apparatus (100) includes: first control means (110) for setting a generation voltage of a generator (MG) so that an average value of a voltage applied to an auxiliary machine (200) is decreased, thus executing auxiliary machine power reduction control to reduce power consumption of the auxiliary machine; second control means (120) for executing high-voltage generation control to increase the generation voltage of the generator than a voltage control under the auxiliary machine power reduction control by inhibiting the auxiliary machine power reduction control in a case where the auxiliary machine is operated with a high load; frequency determination means (130) for determining whether a frequency of switching between the auxiliary machine power reduction control and the high-voltage generation control is equal to or higher than a given frequency; and lower-limit voltage setup means (140) for setting a lower-limit voltage of the generator during the auxiliary machine power reduction control at a higher value in a case where the frequency of switching is equal to or higher than the given frequency, in comparison with a lower-limit voltage of the generator in the case of the frequency of switching being less than the given frequency.SELECTED DRAWING: Figure 4
