Overview of residential bidirectional charging stations
US Residential Market Overview
The US market is finally getting up to speed compared to Japan and Europe. It's quite a mish-mash of CCS, CHAdeMO, priopretary systems. There is also a lot of variation on capability; not all systems can island, blackstart and export.
All are 240Vac split phase for US residential market - I have not included any 3phase 480Vac commercial systems on this list.

EU Light-Duty Market Overview
The European market has advanced faster than the US for a few reasons. First, interconnection certifications are less complex and burdensome compared to California Rule 21. Second, energy markets are more open compared to the US creating greater market incentive. Third, residential homes are often 3phase which seems to have allowed for easier global product development. Also, CHAdeMO also had more traction in some parts of Europe which is ahead of CCS on V2G capability.
