As most long term EV pundits are aware, charging has always been an exercise in "adaptation". Carrying a trunk full of extension cords and plug adapters is a common practice for long time EV drivers due to the need for opportunity charging at a friend's house, local campground, or any other "unknow" facility. Now, for EV owners (and Yes! Even conversion owners) recent development in EV Charging Standards developed by SAE have changed the opportunity charging landscape forever.
This is all good for OEM EV's, but what about my conversion?
If you're EV ownwer and have driven by a public charging staion feeling "green" with evny rather than efficiency, there is hope for you. Not only is the cost of the home-installed EVSE coming down, but the technology to adapt your existing EV to use it is fairly straight-forward and very doable by a qualified installer.
There are many commercially available home charging stations, and the prices for these systems are coming down over the past few years as the component supply becomes more mainstream. In addition, there are many DIY solutions including the JuiceBox - an Open Source Level 2 (15kW) EV Charging Station which is challenging the status quo with a procing model as low as $149.00 US. The package it doesn't include the charger plug or the cable (est at $150.00), so the real price to build is around $300.00. While it may not be for everyone, for the DIY person, this is a significant reduction in cost over commercial available stations. For thos not interested in the DIY approach, you caN see a recently up-to-date list of available EVSEs at Plug-In America's Tracker.
Retrofitting the EV to Use J-1772
To make all of this fly in your existing EV, you will need a J-1772 inlet plug, wiring and the logic board to talk to the EVSE and enable the charger. Since EVSEs do more than just supply power to the charger, there is some handshaking that needs to happen between your vehicle and the EVSE. The logic board provides this communication and logic. With a few extra relays, sitches, and an extra J-1772 plug you could still charge at your neighbors dryer plug as well if desired.
