A charging device for a power storage device includes a current control device configured to selectively enable and disable current from being delivered to the power storage device. The charging device also includes an actuator that moves at least a first portion of the charging device from a first position to a second position, and a controller coupled to the actuator and the current control device. The controller determines whether a predetermined actuation condition is met, activates the actuator to move the at least a first portion of the charging device to the second position upon the determination that the predetermined actuation condition is met, and controls the current control device to enable current to be delivered when the at least a first portion of the charging device is in the second position.
