I have my nissan LEAF 2018 for 3 weeks now and it starts to create a whirring or buzzing sound during L2 charging using my 240V outlet. The sound is coming from near the charge port. Any ideas on the potential cause? I use the provided EVSE charger made by Panasonic.
I also charged using ChargePoint L2 on public areas with no buzzing sound and same on chademo stations.
