Roger and Cor van de Water Thank you both for your valuable input. Roger, your description of your Lester charger matches what I have purchased.The problem I have is that although I purchased the new EV, it is still in Santa Cruz California having some work completed by Mike and Shari @ Electro Automotive, so I have zero experience with the Lester charger and the EV itself for that matter.
It makes total financial sense to try to use the Lester as an on-board charger if possible. I know when I first saw that beast of a charger it scared the you know what out of me. Looks like something used to create Frankenstein monster if you know what I mean. (They dont make them like they used too....;) ) I am not sure how heavy the Lester charger is, but since the back seat has been removed, I am pretty sure I can fit it back there somewhere without too much problem. So I think I will try utilizing the Lester charger first, and attempt to find a j1772 connector and appropriate cable/wire to connect to the Lester 240vac input...... Unless someone out there knows of a reason that the Lester charger will not work. I guess the electronic handshake with the evse equipment will be the biggest hurdle to overcome.
