re UL - as you can see, the design is still being tweaked. It did not make sense to start NRTL process until it's reasonably static. We so far went through 4 major revisions on hardware side - only the last one (8.x) was shipped. Within that one major revision, we went through 8 minor revisions...
The next minor revision (8.9) will have more robust GFCI system (as mentioned above) and better manufacturability (that translates into our ability to keep the prices low while adding features)
The next major V9.x revision will see:
* move to all-SMT design
* upgrade to an ARM Cortex-M3 chip (same as in Arduino Due) as a main controller for per-J1772-head control. For the curious ones, check out our discussion of the new Arduino-compatible board we have designed for this - at http://forum.arduino.cc/index.php?topic=233091.0" onclick="window.open(this.href);return false;, and a recent video of it in action at https://www.youtube.com/watch?v=kPL8APZyh4A" onclick="window.open(this.href);return false;.
* an extensible architecture with SPI / I2C buses on board to support addition of sensors (think temp / humidity / video camera / etc)
* embedded Linux based management of multiple J1772 heads
* remote firmware updates <==================================
* and a full 5-second latency control through web-based API
I hope you guys can see that we are shooting WAY beyond tweaking some dumb EVSEs...
You can be a part of this exciting evolution of charging or bash it from your high tower - your choice ;-)
Cheers,
