Hello peeps. It's been quite a while since I've been on here. I have recieved many emails about the mod I was working on and unfortunately that project got shelved over developing a complete new charger. I've been working with my senior engineering students at Western Kentucky Univerisity on developing a 120/240 combination portable charger and I'm glad to say that it's finished! We are looking to make some enhancements before the production model is ready, but I just thought I'd get some feedback on the pricetag of around $700. The profit margin isn't huge at that number, but we are hoping to get the cost down with volume purchasing of parts such as the J1772 connector. We are looking into UL listing as well. Probably be a while before that happens. Here is a quick rundown of the specs:
120/240 auto detecting
12 amps AC @120
16 amps AC @240 (could be more, but the leaf doesn't need it)
GFCI
Nema L15-30 twistlock connector for switching out of pigtails
J1772 connector with 10Ga wire (a little heavier than we wanted, but was the least expensive/may end up with something smaller for better portablility)
3 LEDs representing AC present, Charging, and Fault condition
Future enhancements:
Metering capability
LCD screen
Bluetooth for connection to smartphones
Any other ideas people are willing to pitch
Look forward to any feedback you all have to offer. I will post a pic/video of the prototype working soon.
