Could we use this evse?

Technical details are sparse. I’d need to see an interconnection diagram.

We don't know at this point. Wallbox won't even put out a list or even one car it is compatible with so far. But, I'd say It's possible it could work. Since this unit uses the DC pins in the CCS connection to tap into the battery directly and uses it's own inverter instead of one in the car, it could work.

My guess is best case scenario, it would need at least an update to the car to allow energy to flow out of the car through the CCS connection. I would expect the car would throw an immediate error and cut the connection if it detects energy flowing out of the battery instead of into the battery.

Info is sparse... but I did find an approximate $4,000 price tag...

Wow, you can install one heck of an on-demand generator and auto transfer switch for $4,000.
And if you went natural gas, you could power your whole house for weeks versus a day on the car battery.

If you had NG.
There's always an option that fits a person/situation.

bi-directional charger will have to negotiate with the car to allow export via dc port....

existing 12v connection points can be used for export today, with no negotiation, by using a $300 pure-sine inverter.... limiting loads to 2000watts or less will enable the on board dc-dc to keep up for as long as the HV charge holds up.

The only EV that will be bidirectional by design and on sale up to now is the 2022 Ford F -150 Lightning truck. GM announced that the 2023 Chevy Silverado EV will do it but it is not official yet. Ford even posted that the Lightning can charge the Mach-E.

the Leaf could do this when it was CHAdeMO.

As far as I know, the Lightening does not have a bi-directional charger.... Ford plans to pre-install an on-board 7kw Inverter, which is passed energy from the HV thru on board dc-dc converter. The 'available' inverter will have a NEMA 240v outlet, and a couple 120v outlets, which you could use for whatever you want.

As a work truck with towing capacity... this opens up the possibility of providing 'shore power' to a trailer/camper, running tools at a job site, running a house (after isolating from the grid), and powering a L2 mobile charger to export some energy to another EV.

We can do this same thing with our MME today, as long as we limit loads to less than 2000 watts since we have a smaller dc-dc converter than what is planned for the Lightning. Basically we could export to a L1 charger via an inverter and 120vAC plug.

They have marketed that if you use new Ford Charge Station Pro with appropriate disconnect, that the Lightning can act as a battery backup for a home.

The inverter onboard to supply power for jobsite use is not the same as the home backup provisions capable in conjuction with the ChargeStation Pro.

aha
it looks like the $1300 ChargeStationPro 80-amp charger might indeed be bi-directional... but only after SunRun also adds a transfer switch to isolate the home before exporting power from the truck... no cost mentioned there, but I'll bet it is several grand for an automatic 200amp xfer switch that communicates with the ChargeStationPro before allowing backfeed to the house.

My point is that is it POSSIBLE to backfeed to your home basically from any 12v connection points on any vehicle if you manually isolate the house first, and understand the max power your vehicle can export.

An typical ICE vehicle with a 'regular' alternator might be ok putting out 40amps x 12v = 500watts
MME dc-dc from HV to LVB maxes out at about 160amps x 12v = 1900 watts
and the Lightning appears to be specced for 7000 watts.

I think it is truly bidirectional. This is from insideevs:
" The Ford Charge Station Pro uses the CCS or "Combo" connector because it needs the two DC pins on the bottom of the connector to deliver power back from the vehicle to the house. When the Charge Station Pro is charging the F-150 Lightning, it's using the J1772 pins at the top of the CCS connector, but when the vehicle is sending power back to the charging station, it does so using the two DC pins at the bottom. "

A transfer switch does not have to cost a fortune. You can get 30 amps manual transfer switch for under $500. Yes that means they are manual and in case of a power failure you have to go and switch to the alternate source.
Most automatic transfer switch are built to interface with a standby generator and I am not sure that would work with a bidirectional CCS system.

ooohhhhhh, I'd love the details on what would have to be communicated via j1772 to enable live DC CCS connector access to the HV pack. Perfect voltage for an off-grid, or hybrid capable Inverter.
