VEHICLE POWER CONTROL DEVICE

摘要

An ECU executes a program including the steps of: calculating regenerative power value P based on a brake pressure (S100); calculating limit charging power WIN(B) to a battery (S102); calculating limit charging power WIN(C) to a capacitor (S104); when it is determined that regenerative power value P is larger than the sum of WIN(B) and WIN(C) (YES at S106), estimating (S 108) that a large regenerative energy sufficient to fully charge the capacitor even if the battery is charged with priority would be generated; and transmitting a control signal (S110) to set output voltage of a boost converter to be not higher than the voltage of the capacitor so as to charge the battery with priority.
