| 摘要 |
The present invention relates to a battery disconnect unit capable of being stably driven, and minimizing damage of a circuit, by having a means to protect the circuit without an additional power source at a high temperature atmosphere. The battery disconnect unit comprises a first main relay (111) electrically connected between a first pole of a battery (120) and an inverter (130); a second main relay (112) electrically connected between a second pole of the battery (120) and the inverter (130); a pre-charge relay (114) connected to the second main relay in parallel; and a self-operating switch (118) connected between the first pole of the battery and the second main relay, and configured to autonomously open a circuit providing an electric power from the battery when a ambient temperature is drastically increased, or when an over-current occurs. |
