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.
[3] Automatic dynamic tariff scheduling requires an emonPi running Demand Shaper Software (now pre-installed), see Smart Charging Setup Guide.
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: UK EVSE IET code of practice: PSEV002P. See installation notes in the User / Install Guide linked below.
To obtain OLEV grant (currently up to £350, UK only) 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.
