A Charging Station is not a Battery charger which is a component found onboard the vehicle. Rather a Charging Station is a place that can supply electric power to an electric vehicle. This can be as simple as a standard 110v or 220v outlet or a W:SAE_J1772 station.
J1772
SAE J1772 is a North American standard for electrical connectors for electric vehicles maintained by the Society of Automotive Engineers and has the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler”. It covers the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. The intent is to define a common electric vehicle conductive charging system architecture including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
There are many commercially available J1772 options as well as methods to build your own, such as the OpenEVSE Project - Open Source Design for EVSE.
Ryans Open-EVSE
All of the OEM Replacement portable units and permanent home installation units appear to cost well over $1000. So I decided to look into other options such as building my own. At this point I have built one of three units. I have yet to add true energy monitoring but intend to add that feature. Stay tuned as I update this information.
