Voltage supply circuit for automobile electrical load

摘要

The voltage supply circuit uses an auxiliary energy source (24), independent of the onboard electrical supply network, for supplying at least one electrical load (34) incorporated in the vehicle door (20). The electrical connection between the auxiliary energy source and the load is provided via an outer side edge of the door. The outer side edge of each vehicle door (20) has a magnetic coil (36) cooperating with an aligned magnetic coil (32) in the door frame, to provide an inductive energy coupling between the auxiliary energy source (24) and the load (34).
