The new charger pin appearance looks excellent. Here are my suggestions:
For unassigned chargers, I'd suggest red strokes for Level 3, green for level 2, gray for Level 1.
Automatically assigned chargers look good in context, but I'm wishing that they had a darker stroke on the border and interior to make them look a little sharper and accentuate the new popsicle shape. In other words, imagine that the image you're using for unassigned chargers was filled in with the SoC color such that you could still see the border edges.
Manually assigned chargers need to use the new popsicle shape after they've been converted. See the attached image for an example, where it's still the old balloon style. In other words, charger pins will always be rendered in the popsicle shape - assigned, unassigned, required, whatever.
