robjg63:

Power surges on start-up can be 2 – 3 times the running power (higher for older freezers).
So if that was still true, the issue could be the startup surge is too high to get a fridge/freezer started.

Wonder if that is still true?

Sounds excessive,

But 2.3KW with a peak of 3kw - its the same as a 10amp 204V socket in your house, So as long as your house circuits aren't popping every time the fridge switches on , you should be fine.... :)

If it is 2200W load and 3000W peak, it would have no issues with a fridge/freezer (they use about 100W, so startup load wouldn't be much higher than 2-300W).

It could run a Microwave too. Maybe not a kettle.

at 2200W it Should be able to run one of anything that you could run on a normal 10A power socket.

Yeah , but consumers never just want to run "one" of something,

Its always "one" of these and one of "those" and "that" too :) :)

Batman: You can also charge during off peak low power price rate and then power the house during peak rates.

Wouldn't want to do it with non lfp but lfp should be ok right?

You can't power the whole house with the BYD. It's V2L not V2H, so it can only power one or two appliances at a time. Still very useful to keep critical appliances running when you have no power.

hmm i didn't know there was a difference.

i thought I read on the news people doing that with their EV6 and their Outlander PHEVs

will there be any future V2H LFP cars ... !?

V2L basically adds a wall socket to the car so you can plug something in that you'd normally plug into the wall.

Ford announced today/yesterday that they're moving many of their vehicles to LFP, including the F150 Lightning, which can do V2H. Of course, the Lightning has no plans to come to New Zealand so, maybe when they make a Ranger version of it.

Domestic sockets are quite capable of outputting dramatically more than their 10A continuous rating, to get stuff started.

In terms of popping circuit breakers, my house has 16A type C breakers. Should only pop if a surge load exceeds 5 - 10x the rated current. i.e. 80+ amps, 22+kW.

Tripping Curves of Circuit Breaker. B, C, D, K & Z Trip Curve

So while a 2200W, 3000W surge V2L setup will do most of what a household socket will do, don't expect it to do everything.

Induction motors can draw 5 - 6 times the motor full load current, so don't expect to direct on line start big induction motors.

A residential fridge should be fine though. Generally the motors are below 500W, so this setup should have plenty of grunt to start them. And they won't all be doing direct on line starts. Some fridges even have inverters these days.

Maybe so but it's an unexpected benefit of an EV with V2L. I can now modify my survival plans accordingly (in Welly)

And the battery is massive compared to the load so will run your fridge/router/phone charger for quite a long time. Bounus if you can hop in the car and drive to an operable fast charger from time to time - in which case you are in business indefinitely.

lchiu7: Some folks are running cables into the house and powering their refrigerators and their ONTs and TVs :-)

2200W with a 3000W peak sounds good to me. How long are these folks getting per kilometer on the dial?

About 390 real world so far but I don't drive till the battery is low Did Welly to PN and back with full air con on and had 20% left.

A friend in the US said he could get V2L on his Chevy Bolt with the kit

https://www.evextend.com/Chevrolet-Bolt-Inverter-Kit.php

Interestingly they talk about the startup surge when turning on a freezer which is a discussion in the BYD forums.

I want to run a fridge or freezer off my vehicle, will this kit work?

The compressor of a refrigerator requires an initial starting current that is much greater than the current it will use once the compressor is running. Refrigerators are quite varied in size and energy efficiency, and as a result, this starting current (also known as "surge current" or "surge power") can vary greatly, even among similarly sized refrigerators. The ability for an inverter to provide this surge current can also vary greatly from product to product. As a result, it is often difficult to know definitively if an appliance can be operated from a given inverter without simply trying it.

Good to see them checking the strength of the door pocket strings! That "tear down" is a joke and probably a badly disguised ad

Just an update froma BYD owner. No sign of Android Auto yet but there is a clone of AA called Headunit Unloaded that works as well. You need to sideload it (The BYD console is just an Android device) and it works well and wirelessly to boot. That's way better than the CarPlay implementation which requires a cable.

And because it's an Android device you can sideload other apps. I have managed to sideload Prime Video so I can watch them on the large screen :-) I also tried Netflix but that failed with a strange error "Device Failure".

It means now while parked, waiting for people in the car, I can enjoy the latest episodes of Jack Ryan :-)

I found the Carplay to be like using an iPad! it was good, but DAMN that screen is too big for the normal CP design. Nice with maps + some controls for audio tho. It was nice having a rental Atto (Mevo), leave it overnight to upgrade and... CARPLAY!

I presume you mean the proper Android Auto, like the Polestar has? or just "connect your Android phone" ala Carplay?

Personally, I just REALLY want to have CP on my phone. Just put it in the phone holder, turn it 90deg wide, switches to CP when the normal BT interface comes on. Easy.
