Abstract
A power circuit protection device for a vehicle including a storage device, a drive motor, and a charging terminal includes a relaying device, a fuse device and a control device. The relaying 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. The fuse device includes a first fuse, a second fuse having a fusing characteristic that is harder to blow than that of the first fuse, and a switching mechanism. The control device controls the switching mechanism such that the second fuse is connected to the power storage device when the control device controls the relaying device so that the second circuit is connected to the control device upon receiving a predetermined charging request.
