Purring / humming noise when charging

[svjoshi]

Has anyone experienced a medium - loud humming noise when charging? I am experiencing this at some, but not all L 1 and L2 stations. Hoping I'm not doing anything wrong. I double checked that my settings are correct on the dash

It is the battery cooling system. If you do a search you can find numerous threads discussing this topic.

Ditto that. Just wait a month or two and you'll have plenty of other charging/range items occupying your mind.
