OpenEVSE is a fully open-source EVSE (Electric Vehicle Supply Equipment) charging station designed by OpenEVSE. OpenEnergyMonitor have been collaborating with OpenEVSE to improve Emoncms remote data logging integration and web UI control. 

An EVSE charging station, is a device an electric car (EV) is plugged into to charge. It communicates with the car to agree on a charging rate that is the fastest and safest rate both the car and the power supply can support.

Caution: this unit is a kit, assembly requires wiring Alternating Current (AC) components that will be exposed to voltages up to 250v. If you do not have the experience and knowledge required to safely work with AC voltages please consult with an experienced electrician for assistance and inspection of your work.

Required Extras 


OpenEVSE units have been designed to exceed the safety requirements for EV Charging Stations from SAE J1772, NEC and UL. 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.

  • Power interlock
  • Pilot signal
  • Ground monitoring
  • Ground fault interrupt
  • Welded contact detection 
  • Temperature throttling
  • EV ID check 
  • Ventilation check
