The term "detachably connected" means that the charging blade assembly 100 may be in contact with the charging slot 43 or may be separated from the charging slot 43.
According to some embodiments of the present invention, as shown in fig. 6 and 7, the charging rail 40 includes a first charging plate 41 and a second charging plate 42, the first charging plate 41 and the second charging plate 42 are both connected to the power supply device, and the first charging plate 41 and the second charging plate 42 are spaced apart to form a charging slot 43. When the charging blade 20 enters the charging slot 43, the charging blade 20 is electrically connected with the first charging plate 41 and the second charging plate 42, thereby communicating the electric storage device with the power source to charge the electric storage device of the rail vehicle.
