I found this interesting accessory for the PriusPHV in Japan. I guess you can boil water for your daytime tea. https://toyota.jp/pages/contents/request/webcatalog/priusphv/priusphv_main_202007.pdf
Yup. Someone did try on our NA version and unfortunately it doesn't work because we don't have the converter in our specification (it's located under the rear seat). You can also cook rice (rice cooker). I believe it's 1500W/100V.
It is mainly for emergency use when the power grid is down by natural or man-made disasters. I can't remember what the exact spec was but IIRC, it is 100v/1500w and with the traction battery and gas tank full, it can supply 4-5 days of average Japanese household electricity. Yap, most Japanese household has very low electricity consumption. A whole house on 10A breaker is not that unusual.
Well it could be used for car camping too! I have noticed that Toyota NA has started added 1500W outlets to hybrid models so hopefully the Prime's will get it. Both the HiHy and Sienna Hybrid (SiHy? HySi?) have optional 1500W outlets (basically standard on upper trim levels).
Is the outlet coming from the traction battery or from the 12v battery? Our 2014 PathHy has 120v outlet but I'm sure it is coming from the 12v battery. The pdf OP linked shows the optional V2H (vehicle to home) power supply unit by Denso. Here is the press release page for the unit. DENSO Develops Vehicle-to-Home Power Supply System for Electric Vehicles | News | DENSO Global Website Not exactly sure how it works. But it connects to the CHAdeMO port of the PPHV and allows both charging of the traction battery (in about ~1hour thus not as fast as a typical DC Fast) and supplying electricity using the traction battery as a power source to provide electricity to the home. This would be a very nice way to use PP as a whole house generator as long as enough power can be supplied by the traction battery.
Good question. I'm not sure. Most 120V outlets so far (e.g. your Pathfinder Hybrid or Matrix/Vibe or other cars) were limited to 100W. I'm guessing it is still 12V battery but I suppose either the battery is beefed up or there's a bunch of "!" in the owner's manual stating that it should be used for short periods only. I mean, it's meant for camping and not V2H in the case of the HiHy and Sienna.
Looks like the HiHy runs off the HV battery so the car has to be in READY mode. That means a PHEV is “better” in the sense that the car can be on without the engine cycling because of the larger battery capacity.
