Wow, I have to say I am flattered. You know you are doing something right when you piss people off... not just people but a whole association. So here is an argument from the other side. A charging station is a pretty simple device, it is basically a smart switch. Once the conditions are right the switch turns on, if not it is off... I think the biggest risk to UK EVSE is their fat profits. Overcharging consumers for this pretty simple device was exactly why OpenEVSE was started in the first place...
OpenEVSE was the first major and probably the largest DIY Charging station project at an estimated 1500 OpenEVSE boards built to date. Safety was the primary concern, only a few highly qualified people got to see the early schematics and source code. Four versions of the OpenEVSE were designed and extensively tested by professionals before the sources were released to the public.
The design philosophy was clear; safe, simple and strictly conforming to J1772, NEC and UL standards as they apply Charging Stations. OpenEVSE implements all the safety checks of J1772 even the commonly ignored (by commercial units) diode check and Ventilation Required state. OpenEVSE also performs an extensive self check to ensure it is wired properly checking for a stuck relay and monitoring ground. The most critical components, the power supplies were implemented using safety certified encapsulated modules.
Open Source also provides the benefit of many people checking the work and providing feedback, the schematics and firmware source code has been downloaded thousands of times, the latest wiring diagram has been viewed 2500+ times. And if there is a bug identified users can upload new firmware.
A discount code for the OpenEVSE store has been created in honor of UK EVSE. For the month of April the code UKEVSE will give 10% off. :smile:
