Title:
ELECTRIC POWER CONVERSION DEVICE AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/053461
Kind Code:
A1
Abstract:
This power conversion device comprises: a high potential-side electric path (22H) electrically connectable to a positive electrode terminal of a first power storage unit (31); a low potential-side electric path (22L) electrically connectable to a negative electrode terminal of a second power storage unit (32); an inverter (20); and a motor (10). The power conversion device comprises: an inter-power-storage-unit switch (40) provided on an inter-power-storage-unit electric path (24) electrically connecting a negative electrode terminal of the first power storage unit and a positive electrode terminal of the second power storage unit; a bypass switch (50, 51) that carries out electrical connection of at least one of electrical connection between the negative electrode terminals of the first power storage unit and the second power storage unit, and electrical connection between the positive electrode terminals of the first power storage unit and the second power storage unit; and a control unit (100) that determines whether, prior to making an ON operation of one of the inter-power-storage-unit switch and the bypass switch, the other is stuck in the ON position.
