Charging cord designs and routing configurations for use during in-flight bidirectional charging of electrified vehicles
Charging cord assemblies for transferring power between electrified vehicles during in-flight bidirectional energy transfer events may include a cable including a wire bundle coated with a conductive foamed plastic shielding to establish a cable subassembly. The conductive foamed plastic shielding is configured to reduce electromagnetic interference (EMI) of the cable. Various cable routing arrangements may be utilized for routing the cable of the charging cord assembly during the in-flight bidirectional energy transfer events.
1. A charging cord assembly, comprising:
a cable including a wire bundle coated with a conductive foamed plastic shielding,
wherein a material make-up of the conductive foamed plastic shielding comprises a cross-linkable plastic material, a conductive filler, and a foaming agent.
2. The charging cord assembly as recited in claim 1 , comprising a first charge coupler connected to a first end portion of the cable and a second charge coupler connected to a second end portion of the cable.
3. The charging cord assembly as recited in claim 2 , comprising a breakaway plug assembly disposed within the cable at a location between the first charge coupler and the second charge coupler.
4. The charging cord assembly as recited in claim 1 , wherein the wire bundle and the conductive foamed plastic shielding establish a cable subassembly of the cable, and further wherein the cable subassembly is coated with an outer jacket.
