<p>The present invention relates to a high-voltage junction box control device for an electric vehicle. An objective of the present invention is to replace a fuse simply by disassembling a sub-cover, and automatically shut off power when disassembling the sub-cover. To achieve the objective, the high-voltage junction box control device for an electric vehicle according to the present invention comprises: a main block (20) in which a power distribution device for distributing power supplied from a power supply device to each electric device of a vehicle is embedded; a main cover (30) mounted on an upper portion of the main block (20); and a plurality of connectors (21) which are disposed on a side surface of the main block (20) and into which a cable connected to each electric device is inserted. A sub-cover (31) comprising a busbar (33) having a terminal is detachably mounted on an upper portion of the main cover (30). A fork (23) corresponding to a shape of the terminal of the sub-cover (31) is disposed on one side of a printed circuit board (22) embedded in the main block (20) and mounted on the terminal of the busbar (33). When the terminal of the busbar (33) escapes from the fork (23) by disassembling the sub-cover (23), power is automatically shut off. If the power is shut off by disassembling the sub-cover (23), or a problem occurs in a relay, a signal is detected and transmitted to the outside by CAN communications.</p> |
