METHOD FOR CONFIRMING LOCKED STATE OF BATTERY CONTACT DEDICATED TO ELECTRIC VEHICLE

The present invention provides a positive locking confirmation mechanism for a battery contact of an electric vehicle. The positive locking confirmation mechanism uses a terminal bolt with an expansive tail section and judges whether the battery contact is in a positive locking state according to a voltage signal measured by a battery management unit. Before the battery contact is possibly not in the positive locking state, the system notifies the user to check and repair the possibly-loosened contact. Consequently, the problem of losing power or generating electric arc in the battery box will be avoided.
