The invention relates to a charging connection device (100) comprising a charging socket (200) and a charging plug (300) that can be inserted into the charging socket (200) in an
insertion direction (PID), as well as a
locking mechanism configured to lock the charging plug (300) relative to the charging socket (200) during a charging process and to release it after completion of a charging process, wherein the charging socket (200) has a charging socket housing (210) and the
locking mechanism comprises an arrangement of balls (212) that are arranged in receiving openings (211) of the charging socket housing (210) and are radially displaceable transversely to the
insertion direction (PID), and an actuating sleeve (230) is arranged axially displaceably on the charging socket housing (210), the actuating sleeve having a section of larger inner
diameter (231) and a section of smaller inner
diameter (232), which Charging plug (300) has a charging plug housing (310),the actuating sleeve (230) has a section of larger outer
diameter (311) and a section of smaller outer diameter (312), and the actuating sleeve (230) is movable back and forth by an
actuator (250) between a release position (RP), in which the section of larger inner diameter (231) allows a radial outward movement of the balls (212), and a locking position (LP), in which the section of smaller inner diameter (232) forces a radial inward movement of the balls (212). The invention further relates to an electrically powered vehicle (400) with a charging connection device (100) and a method for emergency unlocking a charging connection device (100) of an electrically powered vehicle (400).
