<p>PROBLEM TO BE SOLVED: To carry a current for fusion-cutting a fuse using a load other than a step-up converter or a capacitor so as to enable a vehicle to travel after fusion-cutting the fuse.SOLUTION: A power storage system mounted in a hybrid vehicle exerts a carrying-current increase control using a load other than a step-up converter or a capacitor and fusion-cutting a fuse cutting of a current route between a power storage device and the step-up converter. Owing to this, even after the fuse is fusion-cut, the step-up converter and an inverter electrically connected to the step-up converter and connected to a generator generating electric power by receiving power of an engine can be activated normally, thus enabling vehicle travel using the power of the engine. Furthermore, a relay cutoff signal for turning off a system main relay and a full relay cutoff signal intended for all relay devices are output stepwise, so that the system main relay can be controlled to be turned off for a fault by means of a control program (software).</p> |
