PURPOSE: A main connector monitoring circuit of a high voltage battery pack for electrical vehicles is provided to previously prevent electric shock-related accidents due to the battery pack by displaying the safety of the battery pack to a user. CONSTITUTION: A zener diode(4) is turned on if a voltage applied to both ends is higher than or equal to a breakdown voltage. An over-current protective resistance(5) is in connection with the output end of the zener diode. A constant current diode(6) is in connection with the over-current protective resistance. A light emitting diode(7) is in connection with the constant current diode. The input end of the zener diode is in connection with the output end of a plus main connector(3). |
