A system and method for locking a charging port to charge an electric vehicle that includes determining that the electric vehicle is located within a predetermined distance of a charging station and determining that the charging station issues parking citations associated with parking of the electric vehicle at the charging station without attachment of the charging port to the electric vehicle. The system and method also include determining charging of the electric vehicle and sending a command to enable a locking mechanism of the charging port to lock the charging port in place. The system and method further include completing user authentication with respect to an operator of the electric vehicle to disable the locking mechanism to ensure that the charging port is not detached by an unauthorized individual and that parking citations are not issued based on the parking of the electric vehicle at the charging station.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.
