A method for confirming a locked state of a battery contact dedicated to an electric vehicle. In the method, a battery contact screw comprising an expandable screw-tail structure is used and consistency of a signal measured by a voltage detection contact of a battery measurement and management unit is used to determine a locked state of a battery contact, so that when a battery contact is likely to lose a locked state, a user may be reminded to perform a check work, so as to avoid the danger that power loss occurs or an electric arc is generated inside a battery case when a battery contact becomes loose. |
