Document Type and Number:
WIPO Patent Application WO/2019/073652
Kind Code:
A1
Abstract:
A battery module (5) is provided with: a battery (51); a bidirectional DC-DC converter (52) disposed between the battery (51) and an input/output unit (te) connected to an HVDC bus (33); a relay (RL4) inserted between the bidirectional DC-DC converter (52) and the input/output unit (te); and a control unit (53) that switches, in the cases where the relay (RL4) is in the closed state, the relay (RL4) to an open state in accordance with the charging state of the battery (51). While the bidirectional DC-DC converter (52) is operating in charging mode, the control unit (53) receives driving power supply from the HVDC bus (33) via a power supply terminal, and while the bidirectional DC-DC converter (52) is operating in discharging mode, the control unit receives driving power supply from the battery (51) via the power supply terminal.
