Hi folks We were arguing about insertion cycles of various connectors at lunch (something engineers do) so I asked the great god google: Since the Tesla Y came with a portable 32A 240Vac charge controller (ordered the nema 14/50 plug), could just use it as others do for charging. Looking at Wik

Easy way to tell (maybe) is to open it up and see if it has a conventional small 60 Hz transformer to power its internal 12 V electronics. If so, 240 VAC will likely overvoltage those low voltage circuits (operating at 12 V). On the other hand, if it does not have a small 12 v transformer, then it

The G2 units are switch mode, but it has a primary filter electrolytic only rated for 200V. When you connect it to 240v, that capacitor sees about 320v, so generally after a short while it explodes and destroys the power supply. Also, if you just replace the capacitor, it will be fine, and will o

IMO, you can now buy decent heavy-duty well-constructed J1772 EVSEs for rather low cost, and if you own a Tesla, their wall-connector EVSE is a good bargain for what you get. If you just dropped many tens of kilobucks on a new EV, do yourself a favor and get a decent EVSE. Save the included porta

Hi Phil etc I’ve got a couple hard wired EVSEs, a GE with kWh and amps display added and an OpenEvse.com in the garage with KWh and amps display since we have 3 EVs, a Leaf, Bolt and now a Tesla, no fossil fools. Adding a 3rd weatherproof 14/50 mobile home unit I got from Lowes at lunch seems l

It's true, one of the better portable EVSEs ever made was the Nissan Gen 2 unit made by Panasonic Kitchen appliances division: As many of you know, I used to have a small part-time business converting these to L1/L2 capability. They will easily handle 20A continuous (G2 not G3) and can be modifi
