“Vehicles with hybrid drive cannot be used for jump-starting.”
It’s okay to receive a jump if your 12vdc battery is low, but not to give one to another.

jad03060 wroteThanks very much for telling me where to look. That restriction appears to have been dropped with the 50e. The only 45e owner's manual I turned up in a quick search was 2021. It gives the warning you quoted (first image).It’s on page 405 in my user’s manual, Jump Starting, General Information, second paragraph.

For my 50e the printed manual and the pdf downloaded for my VIN from BMW both look like the second image, with no jump-start restriction shown.
So I'm feeling better about the possibility of taking 40A off the battery terminals with a charger but I welcome more comments.
eelnoraa wroteMax power from 12V under hood is about 2kW. Keep equipment below 1.5kW to allow DC converter replenishment in Power Ready mode from HV. A 2.4kW inverter pure sine sells for about $100.Totally agree. You can get a ~10kW generator, tri fuel, for well below $1000. don't mess with your 50e. It is not design to do this. Even if you have proper EV for this, the cost of getting bidirectional setup will easily be upward of $5000 today
No need to turn on engine, just leave the seat belt on and move to back seat. Car in park mode, hand brakes on, all lights off, air con off.

straight up no. 50e is not designed to do this! you said it yourself: “i have so little understanding of the car's electrical systems…” yet still entertaining the idea to try it?! for one, its 12V battery doesn’t have the C rating to handle the load a home system would require
way to think resourcefully, but no offense, this was a st00pid idea…
streborx wroteThose who don't understand, resort to fear. Those who fear, resort to violence. First instinct of any animal is to attack the unfamiliar.During these episodes of natural disasters, the media always reports on the "millions who have lost electric power", and our immediate reaction is catastrophic damage to the power distribution system. This does occur, but in most cases, power companies preemptively shut off power so that downed power lines don't create even greater problems. Regardless of how you source backup power to your home, do you really want to be walking around in a couple inches of water flipping power on and off to your appliances?

i never said the [tech] idea is st00pid as I’m aware it already exists in the market…just the idea of rigging something up in the 50e where it is not designed to support it
nZtiZia wroteSounds like the rational perspective here.LOL

A small home generator is an inexpensive way to provide emergency power and why they are ubiquitous in this country.
45e wroteI am not sure it works like that. With the car on, you are really loading the DC-DC invertor, not the 12V battery itself. The 12V act as a buffer, the sustained power is from DC-DC. Do you know the sustained output of the DC-DC?Max power from 12V under hood is about 2kW. Keep equipment below 1.5kW to allow DC converter replenishment in Power Ready mode from HV. A 2.4kW inverter pure sine sells for about $100.

Now, back up a bit. We are talking about emergency situation here. Even if you can draw 2.4kW from 12V, you will need a 12V to 120V inverter. Since it is a step up, efficiency with load at best maybe 85%. You get 2kW in 120V. What can you do with 2kW? barely enough to heat up some drinking water with a cattle.
I would just go buy a natural gas generator for $600 at costco and call it done. It will be 240V, 7.6KW (32A), so you can directly connect to his to your 200A panel.
