A power supply circuit protection device is used for a vehicle including a storage device, a drive motor and a charging terminal and includes a relaying device, a fuse device and a control device. Therelaying device alternatively forms a first circuit that connects the storage device and the driving motor, and a second circuit that connects the storage device and the charging terminal. The fuse device is interposed between the storage device and the relaying device and includes a first fuse, a second fuse having a fusing characteristic that is harder to blow than that of the first fuse, and aswitching mechanism. When the control device receives a predetermined charging request to control the relaying device so that the second circuit is connected to the control device, the control devicecontrols the switching mechanism such that the second fuse is connected to the power storage device.

    本发明涉及电源电路保护装置。所述电源电路保护装置用于包括蓄电装置、驱动电动机和充电端子的车辆,并且包括继电装置、熔断器装置和控制装置。继电装置选择性地形成连接蓄电装置和驱动电动机的第一电路、以及连接蓄电装置和充电端子的第二电路。熔断器装置被插入在蓄电装置和继电装置之间。熔断器装置包括第一熔断器、具有比第一熔断器的熔断特性更难熔断的熔断特性的第二熔断器以及切换机制。在控制装置接收到预定充电请求而控制继电装置使得将第二电路连接至控制装置时,控制装置控制切换机构使得第二熔断器连接到蓄电装置。
