Understanding Total Power gauge in gas mode

The gas engine generates maximum 53KW. When the battery is completely depleted (no electric range left) and the car demands access of 53KW then where does that additional power come from ? If it comes from the battery then why not power the car from the battery itself ? What am I missing ?

In the attached pictures you can see that the car is consuming 115KW and if the engine tops out at 53KW where does the extra 62KW come from ? If the battery is capable of providing that much power then why is the electric range 0, why doesn't it use the battery power until the battery can really no longer provide any power ?

Thats a lot of reserve power that could be used for pure electric range, in my opinion.In fact in my 6-7 months of using this car I have noticed that even though it shows 0 electric miles, it does putt around on battery only as long as the power demand is under 18-20KW. Only when the power demand goes above that, the gas engine kicks in.
I would imagine/expect that a electric + gas car would be either 100% electric or 100 gas (when battery runs out).
Now I am curious what do other phev hybrid cars do ?
There was an interesting chart posted a little while back (I think it was re Tesla but would apply to every EV using lithium ion). Charging from 0 to 100% of battery it lasted 500 charge (a year and a half?) while one of the other options was charging 30% to 70% was something like 40,000 charges. The less of the top and bottom you use, the longer the battery lasts, just not into infinity and beyond.
