I have the knowledge, the 8 gauge wire an a 40 Amp circuit breaker GFCI and could someone please tell me why I should have a charging station rather than 220V hardwired to a dryer receptacle? I can go either way but 220v is 220V. The charger will cost $390.00 after discounts and will already have the cable attached whereas, I have all the other "stuff" to go for a dryer receptacle but then I'd still have to buy a 220V cable at around $200.00. So the approximate difference in cost is $190.00. Which way is best? The one that gets me 220V charging? Both do that but he wall charger is slicker looking and more of a professional appearance.
I think you are asking do I need an EVSE or just the charge cord with the J1772 connector. YES. It is a safety thing, a simple but costly safety thing. An EVSE is a circuit board with GFCI function and a pilot signal system to tells the car how much the EVSE is rated for, and a relay. The car has to do a 'Handshake' with the EVSE, then the relay closes and then the car's onboard charger draws the amperage that is signaled by the EVSE For instance a 3.3 kW EVSE will tell a Bolt or Leaf to only draw 3.3 kw and not the 6.6 kW the car can handle. Same with the 120 V L1 EVSE.
How long is it to charge with regular volttage, what is that 110, 120? Is that problematic for you, taking too long? If not, if what you've got is working, upgrading seems pointless.
The permanently attached EVSE may have additional features: Wifi reporting, increased capacity, indicators and recordings, etc that the portable EVSE lacks. If you will not miss those features, there is little point paying for them. (I would select the EVSE first, then install the receptacle that matches it's plug)
You can get an EVSE for less than $200 from Amazon: https://www.amazon.com/gp/aw/d/B018A6QK7C/ref=mp_s_a_1_2?ie=UTF8&qid=1527007476&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=16a+evse&dpPl=1&dpID=51qFEoygu-L&ref=plSrch Since it's only 16A, you only need a 20A breaker.
I think OP is asking increased cost of installing in wall direct connection L2 charger worth compared to L2 cord alone if already have 220V receptacle on the wall. But I agree with you, for me shortened time to charge by L2 is not worth the cost altogether. I only go out once a day 99% of time, and I do nightly charge (L1) for next day. Feel no need for L2 charger.
Some stock 110vac EVSE’s will run on 220vac with a small modification, I know my voltec does. Also there are dual voltage EVSEs available shipped to your door for $150 Is it financially worthwhile, nope Only good for convience
Well, I'll fess up. I am retired and don't drive every day, most of my trips are local within 7-15 miles. With that in mind and some of the thoughts you folks have passed on, I probably don't need the L2. In taking trips out of town and staying in hotels I probably won't use the charger anyway for fear of theft/destruction of property. so will probably not use the EV at all on those long trips. Besides, an extension cord is discouraged.
Could you please tell me what Amp circuit breaker you are using for your ESVE line (or anyone else) and do you have an in-line CGFI?
Yes, I have the 120V CGFI but i am going to install a 220V receptacle and the amp needed would be 30 Amp with 8 ga feed. Right?
you should be able to find that info on line. i thought you decided you didn't need L2? are you prepping for a future bev?
I figured that I may as well upgrade to L2 since I already have the wiring and other materials sans the ESVE line. So I'll be out around $200.
I am a bit confused about what is being asked for in this thread. You cannot just connect the J1772 plug to a cord and attach a 240V style plug to the other end of the cord and plug it in to the 240V socket. There has to be something to implement the J1772 protocol, whether you call it an "EVSE" or a "Charging Station" or whatever. Fancier units have WiFi usage reporting and such, but you cannot get away without the basic J1772 support.
I'll be using an EVSE, not to worry. Thanks for being concerned, but all I'm doing is going from the circuit breaker to the dryer receptacle and from that point use the EVSE to connect to the Prime.
