New (Black cord) 120V EVSE more sensitive than old one?

[cnicholson]

My original 120V EVSE charge cord (orange lead) died after one week and would not provide any charge, even at 8 Amps. The new one worked fine for a week, but started tripping last week when on 12Amps. We had a heat wave, presumably putting more load on the grid-- perhaps that made a difference. I got a volt meter and figured out the the GFI plug was starting at 119V and dropping to 105V and would trip after 30 mins of charging.

I rigs up thick extension cord to a closer outlet and the voltage dropped from 120/121 down to 117/116V, and it fully charged twice.

Then today, I tried to charge off 120V at work-- which previously worked a couple of times with the old charging cable. You guessed it-- it tripped after about 30 mins.

I didn't bring my volt meter to work (I will), but was curious if others have noticed increased sensitivity on crappy outlets with the revised charging cord.

Thanks!

Sounds like your plugging into marginal outlets that have long wiring runs, nothing wrong with the charger.

I have only used mine a couple of times but it did seem to be warmer than the old one did.

The short pigtail and the charge unit itself seem to run pretty cool. The J1772 connector, on the other hand, seems warm. I never noticed that on the old one.

My new cord (3rd gen?) works just as the old one(2nd gen?) did, both at home and at work. Both places I use a kill-a-watt at the EVSE end. At home I use a 25' 12/3 extension cord.
