Publication number: 20230420971Abstract: An electric power source control device includes an acquisition unit that acquires a charging/discharging current of a low-voltage battery, a detection unit that detects a predetermined operation executed with respect to a high-voltage battery, and a determining unit that determines presence/absence of an abnormality with respect to a connection state of the low-voltage battery, based on the charging/discharging current. When the predetermined operation is detected, the determining unit determines whether a state in which the charging/discharging current is no greater than a first threshold value continues for a first duration of time, controls an electric power converter when the state continues for the first duration of time, and further determines whether the state continues for a second duration of time longer than the first duration of time, and determines that the connection state of the low-voltage battery is abnormal when the state continues for the second duration of time.Type: ApplicationFiled: April 13, 2023Publication date: December 28, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takuya ITOH
