The purpose of the present invention is to effectively suppress an increase in the capacity of a power storage unit. This vehicular power supply control device (1) is provided with a discharge unit (3B), a control unit (5), and a temperature acquisition unit (5A). The control unit (5) controls a discharge operation so that the output voltage from the discharge unit (3B) reaches a target voltage. The temperature acquisition unit (5A) acquires the temperature of a power storage unit (7). The control unit (5) sets the target voltage to a first target voltage when the temperature acquired by the temperature acquisition unit (5A) is within a predetermined first temperature range, and sets the target voltage to a second target voltage higher than the first target voltage when the temperature acquired by the temperature acquisition unit (5A) is within a predetermined second temperature range higher than the first temperature range.
本发明有效地抑制蓄电部的容量的增大。车载用的备份电源控制装置(1)具备放电部(3B)、控制部(5)及温度取得部(5A)。控制部(5)以使放电部(3B)的输出电压成为目标电压的方式控制放电动作。温度取得部(5A)取得蓄电部(7)的温度。在由温度取得部(5A)所取得的温度处于预定的第一温度范围内时,控制部(5)将目标电压设为第一目标电压,在由温度取得部(5A)所取得的温度处于比第一温度范围高的预定的第二温度范围内时,控制部(5)将目标电压设为比第一目标电压大的第二目标电压。
