Firmware for OpenEVSE controller used in OpenEnergyMonitor EmonEVSE units solde in (UK/EU) via the OpenEnergyMonitor store. In collaboration with OpenEVSE.

https://shop.openenergymonitor.com/ev-charging/

Based on OpenEVSE: Open Source Hardware J1772 Electric Vehicle Supply Equipment

Changes by OpenEnergyMonitor:

  • Disable AUTOSVCLEVEL (autodetection is designed for split-phase)
  • Charging level default to L2
  • Set MAX_CURRENT_CAPACITY_L2 32 (limit for single-phase charging in UK/EU)
  • Add '.EU' to version number
  • Enable LCD Redraw every couple of min (required for EMC/CE)

EmonEVSE

EmonEVSE (non-tethered type-2 EVSE unit)

  • PP_AUTO_AMPACITYenabled to set max current based on non-tethered cable connected
  • Three-phase option with THREEPHASEenabled to calculate three-phase energy

Resources


Firmware compile & upload help: firmware/open_evse/LoadingFirmware.md

NOTES:

  • Working versions of the required libraries are included in the libraries/ folder
  • PlatformIO / Arduino 1.6.x+ is STRONGLY RECOMMENDED for compiling OpenEVSE. Older versions of Arduino will build sketches which are too big to fit into OpenEVSE, unless features are disabled.

Falsh pre-compiled using avrdude:

$ avrdude -p atmega328p -c usbasp -P usb -e -U flash:w:firmware.hex
