The ecosystem isn't there yet to just plug a car into the wall and have it power a home. But I've been using my EVs as home battery backups during power outages for 8 years now. I don't have any of that fancy stuff, just a 2000 watt inverter that gets clamped onto the car's 12V battery under the hood, and an extension cord I run into my kitchen to plug in a power strip for the fridge/freezer, TV, wifi router/ONT and laptop charger. The car's DC-DC converter can produce around 3000 watts, but I never approach that as I don't want to damage it. My VW ID.4 theoretically is V2H capable according to the advertising, just waiting for someone to sell a box that plugs into the CCS port to make it happen.
- kkfx 4y agoThat's a backup for fridge, but hardly for a home: how about cooking? heating/cooling? BTW the "ecosystem" is not there IMO because no one who design such systems use them, really. I have a modern Daikin hot water system formally "integrated with the solar" etc. It's not integrated AT ALL, people who sell it do not even know how to use it's crappy ModBUS interface and that is designed just to tweak it's functioning based on the current energy price from the grid NOT depending on a p.v. system and that's one of the state-of-art new gears... Essentially IMO no one have ever tried to tackle nor maximum self-consumption nor autonomy. And this is the very first issue. The second issue is that nobody ever try to push standards. They sold crap in a state in the past we would have call "early stage prototype" as a finished product. Given actual prices no real revolution can happen in technical terms.
