CCS charge port: extending the HV DC leads
Posted: Fri Apr 28, 2023 3:17 am
I have a BMW i3 charge port, complete:
It transitions from unshielded to shielded HV cable within ~4"/100mm:
I need to extend the HV leads a considerable distance, on the order of 6'/2m, to a HVJB. I'd like to avoid an additional junction box that would merely contain HV connectors for extending leads. I'm considering things like shear bolt connectors to connect old to new leads; they are compact and quite reasonably priced. The shielding would not be maintained, though.
I see that both this BMW i3 and the Tesla Model S Charge Ports use shielded leads, and I'm wondering it this is needed, or desired. I'm having trouble imagining when there would be significant EMI when charging. DC from EVSE, DC battery . . . what would cause EMI on these leads?
What have others done to re-use existing JY/OEM CCS Charge Ports and extending the HV DC leads?
