1. A fuel cell system comprising:
a plurality of high voltage units that operate at higher voltages than an output of a fuel cell; a plurality of high voltage unit controllers that control the plurality of high voltage units, respectively; a general controller that controls the plurality of high voltage unit controllers through communication lines, respectively; and a plurality of dedicated wire lines provided between the general controller and the plurality of high voltage unit controllers, or between the plurality of high voltage unit controllers themselves in order to send a shutdown signal used for stopping the plurality of high voltage unit controllers to the plurality of high voltage unit controllers. wherein each of the plurality of high voltage unit controllers includes:
a monitoring unit that monitors the hard shutdown signal sent through the dedicated wire lines; anda shutdown unit that, based on a monitoring result of the monitoring unit, stops operation of the high voltage unit that is under control of the high voltage unit controller of interest, and further stops at least part of control functions of the high voltage unit controller of interest. |
