Another power option besides off, accessory (12v), and on?

Back when I-95 was shut done because of weather, if I remember correctly EV cars batteries out lasted ICE vehicles. This leads me to think that EVs with a good level of charge 50%+ will run a very long time when it’s not moving, eg “idling” in Park and when using moderate heat or a/c?

Interesting comparison and a nice bonus to an EV.

Didn't follow up reading it but thought I saw a post or news article somewhere about using your EV during a power outage at your house. Getting rid of exhaust fumes does come with benefits.

Yes, and there are several threads on it. The key is using seat heaters instead of the heater, which is a big power draw.

There are multiple reasons that are pretty clear to me, not just one. Some are the same reasons I'm suggesting an ad hoc way of disabling the gear shifter, not just while charging.

You don't have to agree with me, but it isn't a big ask considering competitors have modes akin to what I'm after (Camp, Pet, etc.).

I didn't say I don't agree with you. I can think of reasons you may want full power without the car being in Ready mode. But you didn't seem to know the reason the gear shifter was disabled when the car is plugged in. That reason seems clear.

Perhaps I have ICE brain too much and not wanting to use the On mode (put foot on brake, go into drive, take off) at times when I want to just use climate settings for comfort or USB ports for charging w/o draining the 12v battery.

But I can’t seem to find a mode where these things (climate settings, radio, USB ports, etc.) are powered by the MME’s main battery....

I think it remains same. With an ICE, in order to use climate control or radio/USB without draining the 12v then you have to start the engine.

Same with your BEV. In order to use climate control or radio/USB without draining the 12v then you have to start the HVB system.

I don't see any difference here. ???

Turn vehicle on. Set timer to off. But phone and fob in faraday bags. You well not be able to shift into gear.

A good analogy for both ICE engine start and BEV full system needs to be on to power climate control, charge devices, etc. w/o draining the low volt battery. Right now for the MME that seems to be the case.

But maybe when they can design a new technology better (BEV vs ICE) look to do so with other capabilities? Tesla has its Camp and Pet modes for instance.

As for the difference...would disabling certain systems save electricity? I don't know how much draw the security system, autolock walk sway door lock sensors, if power goes to components needing to drive the vehicle would take but if that energy could be saved in a full battery accessory mode (Tesla's camp mode) why not? The extra safety feature of disabling the gear selector wouldn't hurt either as for the differences that could be made by designing new technology that isn't in the same mold as an ICE vehicle.

Not a huge deal, but I do see BEVs in the future having more modes than just those that emulate ICE vehicles.

LOL that is one workaround.

I think any 'camp or dog mode' would still require the HV contactors to close anyway so not much extra amp draw for the other unused modules. The power draw savings are likely to be so minor that it doesn't make sense to shut them down. Complexity might outweigh the small benefit IMO. Not positive though. Would be interesting to see what systems could be shut down and what the comparative consumption would be.

MME consumption with key-on, no heat or AC is typically 400W, comparable to some flat screen TVs, FWIW.

Can jump to 8kW for a while with Max Defrost on.

Would max defrost ever activate by itself? If so, then a camp mode would make sense. ??

Remote start does run everything with the gear locked. ICEs with auxilary heaters can run in "camp mode" where just the parts required to run the heater (that is the fan motor) is running (for about 30 minutes). The problem might be that there is no problem.. when running auxilary heater in an ICE there is no 12V being created. In an EV it is no problem keeping the DCDC running, but it seems that since the software is created for both EV and ICE where ICEs has no way of creating 12V without the engine running the software will not support it.
