This is an EVSE control board that we have made for several years. With a two line backlit LCD display. That shows its status more clearly than just the 4 LEDs (they still work).It is not a complete EVSE. It generates the Pilot signal and monitors the changes the car makes to the pilot signal. When this is done, power is supplied to the car by a contactor you supply. It is 100% true to the J1772 standard and if you assemble the EVSE as detailed in the instructions it will comply with the National Electric Code NFPA 70 section 625. The board operates on a 24 volt center tapped transformer. This will also power your contactor that actually switches the powerline.
You also provide a suitable enclosure for the EVSE. This circuit requires you USE a circuit breaker for the 120 or 240 power that has GFI (ground Fault Interruption). It cast a few dollars more but it makes it safe.
The unit has 4 LEDs that show the units status, READY, CONNECTED, CHARGING, and FAULT common to all EVSE 4.2 boards but also has. A two line backlit LCD display. That shows its status more clearly than just the 4 LEDs. The unit has a rotary switch to set the circuit breaker amperage you have chosen 10 to 100 amps.
The actual charging is 80% of the breaker you select. So if you have a 30 Amp GFI breaker the pilot will send that 24 Amps is available to the car. If the car does not need 24 amps it only uses what it needs. If the production car can charge at higher rates it will throttle charging back to the level sent in the Pilot signal. This is part of something you are going to build and need to fully understand.
