Electric Vehicle Charging
Catenary Systems
Inductive Charging
•Heavy goods vehicles (HGVs) draw electric energy from a catenary system using an adaptive pantograph to establish contact with the overhead wire.
•Wherever there is no overhead line, the HGVs switch over to their diesel-hybrid drive system.
•Systems are being investigated for the I-710 Corridor in Southern California.

•Inductive charging uses an electromagnetic field to transfer energy between two objects,
•Energy is sent through an inductive coupling to an electrical device, which can use the energy to charge batteries or run the device.
