I don't know how these vehicles operate, but assuming the car's engine failed, can you still run the vehicle in Hybrid mode like a spare tire?
 
usually the electric motors are in the Trans. in my car, there are 2 electric motors in the transmission.
one is clutched to the Crank, that acts as both starter and generator, and the larger traction motor. the Engine running, (and regen on braking) is what charges the batteries.
without the engine it can only go a couple miles on battery alone.

 
2005 prius, I got some cheezy coils on ebay. One failed. Car hated this so misfired for 5 seconds then shut down the gas motor.

I did indeed have electric power, for maybe a mile, then it cut to neutral and called it quits.

I fixed the coil and fired it up. Engine sat around 3500 RPM just tooling around at 40 mph trying to refill the horribly depleted HV battery. Came out of it in a few miles.
 
The beauty of hybrids is that the battery is pretty small. So the expense and safety issues with bigger batteries are not as prevalent.

Of course you can’t go long distances on electric only, but you can get much better gas mileage from the fuel you have.

I think a good question might be if a PHEV can go on the battery only if the engine failed. I’m a PHEV fan over HEV and EV, personally, though I own an HEV.

Agree on every point
 
The Chevy Volt was, in my opinion, among the best ideas around. 50+ miles of plug in range, operation on battery alone, engine alone or a combo of each. Turned out to be among GM's most reliable cars too, at least in the short term. Although the batteries in earlier examples are failing now.

I absolutely love the idea of a plug in hybrid. Especially if solar is involved somehow.

From an engineering point of view, the Prius is more efficient "energy wise" than a Bolt EV. The BTU's burned in a power plant, to power an EV a specific number of miles, is almost 2x higher than the BTU's burned in a Prius to travel the same distance.

But keep in mind the batteries in a typical plug in hybrid see many more "full cycles" than a 100KWH battery in a Tesla. I fully expect the ioniq plug in hybrid to have early battery failures. As just about every 20 mile trip is a full battery cycle. And the cells chosen are not the Yuasa 5000 cycle cells.

In theory the PHEV batteries should have a bit more margin (unused capacity) to them, as compared to an EV.

Take the margin out of either and you start losing cycle life. Intercalation stress and strain on the graphite anode causes cracking and other issues....
 
The volt had a good amount of cushion built in to the batteries... 100% is really only 80% of the full pack capacity. That way if a few cells degrade, the driver will likely never notice.

There might be a cushion at the bottom too,( 0% really like 20% or something) but it's been too long since I looked it up...

As a past owner of two different plug ins, imo the answer is yes it can. You could have a blown rod and you can drive around forever in EV mode. On the ones I had, the problem was to run the engine every month or so to lubricate and exercise it. The Volt would tell you it is time. If you didn’t listen, it would start the engine itself and roll it’s headlights in frustration. If you didn’t put gas in for a year, which happens, it would say wth and start the engine and run the old gas out of it.
The first Volt had about a 16.5 kwh battery depending on the year. There was about 10.5 useable range with a 3 kwh buffer on top and bottom.
Regular hybrids have a buffer top and bottom too. The 07 I had was going strong at 15 years with no battery issues and no head gasket, oil burning,etc etc internet makes it sound bad when it really is not the case for you, issues.
