Took a look at the vehicles they say they've been able to discharge and there appear to be no GM vehicles. Not sure if that's because they haven't tried on one or if GMs software won't allow it to be discharged.

My initial guess was that it’s because the GMs with larger batteries switch between parallel to series battery configuration when charging, but the EV6 is also an 800 volt battery, so maybe not. Or maybe when the GM software causes this reconfiguration there are hardware pieces that disallow discharging.

I’m not sure.

For V2H charges it looks like:
GM has its own proprietary system
Ford has its own proprietary system
Tesla Cybertruck has its own proprietary system
Kia/Hyunda appear to be working with Wallbox and Wallbox says it's system will be able to work with other V2H capable vehicles in the future
Emporia has a Honda concept vehicle on their V2H webpage that may indicate they're partnered with Honda for a V2H setup

SigEnergy says their proprietary system can be used on any vehicle regardless of whether it has V2H capability built in... Still unclear on how exactly their getting the vehicle to discharge and what safeguards are in place to prevent damage to the vehicle...

If I've missed any let me know!

Nissan’s Leaf still uses the CHAdeMO for V2X. CHAdeMO is the only standard in the world that was designed with V2X in mind. For various reasons, it’s being phased out, so it’s really only relevant in North America if you own a Leaf or a Mitsubishi Outlander PHEV (and a few other almost entirely irrelevant xEVs).

I thought the outlander PHEV was equipped with a J-1772 port… did they originally launched with CHadeMO?

Enphase is coming out with a bidirectional charger for the global market sometime in 2026

Enphase presents bidirectional EV charger

The microinverter company has disclosed details on the architecture of its IQ Bidirectional EV Charger, which will be available for sale in the second half of 2026. It is reportedly able to deliver up to 11.5 kW of bidirectional power.

Their AC port is J1772.
They are still using CHAdeMO for DC charging.

It’s difficult to tell from a skim of their document whether they require their energy storage system for the bidirectional charger to operate. It seems to be the case. If so, it’ll be another $10k system. Totally worth if if combined with solar and etc., but as someone who already has solar—and more importantly an inverter—installed, this would be a huge added expense. I’d be better off buying $10k worth of batteries (100 kWh of storage) and saving my truck battery for driving and longer-term emergency use via V2L.

In section 4.1 of the paper it shows just the EVSE the meter collar and the vehicle. Seems like it can operate minus their battery storage system. Section 4.2 lays out the integrated energy system with their batteries.

I don't have solar or battery backup systems so using only the vehicle would interest me.

Thanks! I clearly haven’t read it in detail.

Looks like a nice approach.
