i just got kiev back today with the new style On-Board Chargger, calling it OBC2. It has a date code of 2018.05.17 and is quite different from the 2012 version.
AC Input (no more doghouse)
Current Sense Resistor and Fat Blue Caps (snubbers?)
These will be much easier to repair-- no Waffle Plate™, all the high power diodes and transistors can be seen along the bottom board edges.
