I am sorry to hear you moved away from OpenEVSE. OpenEVSE is in fact designed for the international markets and does support locking of a Type 2 socket (with an inexpensive driver board) and proximity pilot for IEC cable ampacity detection. OpenEVSE outputs the commands for Lock/Unlock on the ISP header pins.
OpenEVSE also supports all the required safety checks required by IEC, SAE and UL such as GFCI, Welded Contact Detection, and Ground Monitoring.
Hi Chris,
While browsing your store, i can't seem to find a kit which supports locking the Type 2 socket, nor the driver board.
I also can't seem to find the schematics or any reference to the locking support in the Changelog on your Github page?
Ref the GFCI, this is usually handled by a type A (AC current only) or type B (also detects DC current) Din Rail type GFCI.
It seems that type A is ok for use in the USA, but in Europe some car manufacturers like Renault demand a type B to be used.
While welded contact detection would be nice to add to the SmartEVSE, it's a feature that has been omitted by other charge controllers as well (for example PhoenixContact or Wega 879-101).
I designed SmartEVSE to be used with Smart charging in mind, as i only have 3x25A available for the house + charging the Roadster and Model S. And charging at a fixed amperage would have probably melted the mains fuses at some point. Now i can charge the roadster at 25A (single phase only) and the Model S at 3x25A, and the SmartEVSE will automatically lower the charge current to the EV while we are cooking or the washing machine is on.
