Obviously this won't be usable by any current or planned versions of the PHEV (so apologies for off topic), but it did set me wondering about fast chargers in general. If the charging process is 90% efficient (seems unlikely any real-world system will do much better than that), this means 35kW of waste heat that has to be disposed of somehow without raising internal temps too high. I'm sure this has been thought of, just keen to know how it's done.

I can see that a 200hp ICE running at close to full power will produce much more waste heat than 35kw, but that's only intended to happen at reasonably high speeds, where you can just dump it into the atmosphere (and still parts of the engine will be red-hot). But if you tried that while the car was standing still, you'd soon find out what that red over-temperature light means :twisted:
