EmonEVSE is a fully open-source WiFi connected charging station (EVSE: Electric Vehicle Supply Equipment), developed by OpenEnergyMonitor in partnership with OpenEVSE.
The EmonEVSE has been designed for European installation with IEC 60947-5 (type 2) socket and 32A single or three-phase support. The unit is fully CE certified and is fully assembled and tested in the UK.
See EmonEVSE Datasheet for further details
[1] Due to hardware limitation three-phase EmonEVSE will always calculate energy (kWh) assuming all 3-phases are being used. E.g. if a single phase EV is connected to a 3-phase unit (e.g Nissan LEAF) the LCD will calculate energy delivered as if the EV was charging using 3-phase. Charging function is not effected. To avoid incorrectly calculated energy display we recomend only charging three-phase enabled EV's (e.g. Tesla, Zoe, BMW i3) from three-phase EmonEVSE's .
[2] Solar PV divert requires emonPi solar PV monitor (or another MQTT solar PV data source). See EmonEVSE Setup guide.
Safety
EmonEVSE units have been designed to exceed the safety requirements for EV Charging Stations from SAE J1772 and BS EN 61851-1-2011. Before supplying power to the car (and continuously while charging) the EVSE unit conducts a number of checks, no power is supplied until all the checks have passed.
EmonEVSE should be installed by a certified electrician following local code of practice. See installation notes in the Install Guide Datasheet.
To obtain OLEV grant the EmonEVSE must be installed by an accredited OLEV installer. See UK directory of OLEV accredited installers: Download from gov website or view interactive map.
