Noticed this morning when stuck in traffic and in Charge mode the onboard charger began to rev very high. I have never had it do this before in the 5 years of ownership. Not the engine itself but the charger. Anyone else experienced this? This was at standstill, not the engine itself.

What are you talking about? The engine is the "on board charger"

The Generator is driven by the ICE to charge the battery and supply power to the front and rear electric motors. The higher the demand the higher the ICE will rev to drive the generator.
Generator Charges the Battery which in turn drives the EV Motors which drive the wheels
On Charge and High Speed the rear electric motor is disabled and the Motor turns the Front wheels via the Clutch or 1 speed CVT
Yes the greater the demand the greater the Generator output but there should not be any Vibration.
Vibration occurs when items are loose and rubs against another item. Might be a damaged Mount or a Bushing.
These are the parts of the original post that I'm struggling with:
"the onboard charger began to rev very high"
"Not the engine itself but the charger."
I want to know what the thing is, that is revving high, that isn't the engine.
The post doesn't make sense according to what we know about the car.

The onboard generator (engine) ie the self charge button over revs the engine when activated.
Never had this before, usually quite quiet. Revs really high. Turn the charge button off, engine drops to idle. This is with a half full battery. Only began doing this the past few days. I have used this option lots of times in the past and its always been quiet and unobtrusive. Its like its going to explode now!
Its due a service so will inform them when I book it in.

OK.
So the engine is over-revving, when you put the car into Charge mode.
It is normal for the engine to increase RPM when you select charge mode, because you're asking it to burn more fuel, so that it can charge the battery.
It is relatively unusual for the engine to be running (AKA idling) when the vehicle is stationary, if the car is not in Charge or Save modes.
Are you running heating/air conditioning at the same time? Is that also making a demand for power?
Please let us know what the dealer advises.

Have used the Charge button hundreds of times within my 5 years of ownership and it has never over revved like this previously. Turning the heating on or off does not affect it. The rev counter remains on idle whilst this happens. Its an odd one. Going to book it in next week for the annual service so will find out.
