MECHANISM FOR CONFIRMING LOCKED STATE OF ELECTRODE CONTACT OF ELECTRIC VEHICLE AND APPARATUS FOR CONFIRMING LOCKED STATE OF BATTERY MODULE ELECTRODE

A positive locking confirmation mechanism is provided for confirming a locking state of a terminal bolt of a battery pack of an electric vehicle. A vehicular controlling unit monitors whether a voltage signal detected by a voltage sensor of a battery management unit is stable. According to the monitoring result, the vehicular controlling unit can recognize the terminal bolt that is possibly loosened. The battery management unit detects the voltage signal of the corresponding battery pack and locking state of the terminal bolt. If the terminal bolt is possibly loosened, the battery management unit provides an identification code of the terminal bolt. According to the identification code of the terminal bolt, the corresponding battery pack is checked and repaired easily.
