I don't see that the PHEV is any more complicated than a BEV - both have motors and regen systems and batteries. Any argument against a PHEV and possible battery pack issues applies just as much to a BEV, of course. So that argument against the PHEV isn't really vary fair.
I'm not sure how you came to that conclusion? PHEV's have 2 entire power systems, one of which is an ICE with hundreds of moving parts, wear items, and a gearbox to mash it all together. The EV side is likely to be the most reliable power system in a PHEV.
You said that you wouldn't want a PHEV partly because of the batteries.
PHEV's are far too complicated for my liking and I'd hate to own one outside of warranty when something breaks or the battery pack dies.
The same argument about batteries applies to BEV, of course, but with the issue that you can't do anything with it if the battery system has a problem. You could, in principle, drive a PHEV on ICE alone (I'd like to see a "get home" mode for just this situation but I don't suppose the manufacturers have thought of it).
The point about PHEVs is that they bridge the gap between the ICE ecosystem and the BEV ecosystem. It allows the infrastructure to be built up to support future wholesale use of BEV. It gets people used to running an EV, charging at home to allow for EV-only short local journeys but still having the fallback of the hybrid system for longer journeys.
As the chap in the video I posted said, they had a pure EV for nearly a year and found that they ended up just using it for short local stuff because they couldn't be sure that they could charge it if they went outside of "home radius". So then they used traditional ICE vehicles for the longer stuff. The PHEV was avoiding that issue (because you just need a traditional fuel filling station) and still doing over half of the miles driven in EV mode because they charge it overnight.
I also agree with him that the subsidy on BEVs is misguided. They're generally bought by wealthier people anyway (they're generally expensive things) and they often have tax breaks that make them even more attractive to those with accountants. PHEVs would make a much bigger impact on emissions, not just CO2 but also NOx etc., in urban environments. Better to encourage people to move that way and then support the infrastructure to charge them (much smaller charge required, don't forget, so less infrastructure changes required in the short term).
In the UK, the Tory Government reduced/removed the encouragements to the wholesale move towards renewable generation. Every house should be generating power (PV) and storing it locally for use (battery store), for example, which could be done at reasonable cost (economies of scale apply here). This could allow for self-charging a PHEV, for example, or even just running the house in the evening on "stored volts".
I wouldn't drive a BEV in the UK at the moment. I'm thinking about a PHEV, however, because it will work well here.
