The contactless energy transfer technology contains ground-based and vehicle based segments. The two key components to the ground based system are the power electronics element and coils, which enables vehicles such as the C-AGV to receive energy both under the quay crane and the stacking cranes areas. In addition to the ground based system, the vehicle based system employs the same technology and uses super capacitors to store the energy, which is then used by the specially designed electric wheel motors.
