Sigenergy fast charger compatibility

[markamcd]

It seems no GM cars are listed on Sigenergy compatibility list of manufacturers. The list includes most other EV manufacturers.  Does anyone know the problem?  The charger Sigenergy model #11080012 https://www.solarelectricsupply.com/sigenergy-dc-ev-charger-25kw is very capable and seems to be matched electrically very well (DC-DC). Is this a communication/software handshake problem?  Can we assume a fix is in the works?

I was pretty sure I read somewhere that GM's bi-directional charging can only be used with their proprietary charging system but can't find a definitive source. The Ultium cars (or whatever GM is calling them now) will do it, it's just a matter of if you can use a non-OE system to use the feature.

 

Contacting Sigenergy might also provide you a good answer. The EV forums here are pretty quiet...
