Padlock

A padlock comprising:

• a body
• a shackle manually movable relative to the body between a locked shackle position and an unlocked shackle position;
• a blocking mechanism arranged to adopt a blocked state and an unblocked state for blocking and unblocking, respectively, the shackle in the locked shackle position
• a locking element rotatable relative to the body for controlling the blocking mechanism;
• an actuator configured to adopt a locked state for locking the locking element and an unlocked state for unlocking the locking element;
• an actuating element operatively connected to the locking element and arranged to be manually manipulated to move the locking element when the actuator adopts the unlocked state;
• an electronic control system arranged to control the actuator;
• and
• at least one energy harvesting device;
• wherein a movement of the actuating element from an unblocked actuating position to a blocked actuating position causes the blocking mechanism to switch from the unblocked state to the blocked state and wherein each energy harvesting device is arranged to be actuated by at least one of movement of the actuating element from the unblocked actuating position to the blocked actuating position, a movement of the shackle, or by a movement of the locking element.
