Re: EVSE options for 2013 Leaf

Sun May 26, 2013 3:11 pm

I had a minor problem (slight warming) and Blink came out and changed out my cable for a new one that had the crimp problem rectified. They also updated the CT at the same time just to prevent a future service call as there have been a few isolated problems with this and the GFI. They left my Blink set at 30 amps...

He said he personally has never received a call from a Leaf owner with such a problem. He did admit that there were a relatively few Blink charging stations that had had such a (isolated manufacturing defect) problem, but my understanding from him was that their policy was to correct them and not to just limit their power. I understand that he is hardly an independent, unbiased source for information, but can any 2013 Hi-power Leaf owner attest to evidence of low-power Blink charging? Please post if you have...

We are relative newbies, but did a lot of research ahead of time and it seems to have paid off. Here is what we are using with our 2013 Leaf S with the charger upgrade (which we really like)

Schneider EVLink 30 amp L2 indoor charger from Home Depot. It worked great but we got a recall notice and could not use for about 1 month until they got new J1772 plug and cord, which they installed for free, and we've had no problems. This unit is on a 40-amp circuit (and we had the electrician fit it with a NEMA 14-50 plug so we can take it with us if we have to) and seems to make full use of the faster charging as we can charge in well under four hours We start most charges when the SOC is between 25% and 50%, and see a gain of approx. 30% SOC per hour to 80% SOC. The last 20% seem a little slower the few times we've gone to 100%. (This unit disappeared from Home Depot's website about a week after we bought it, perhaps due to the recall, but I noticed they now have it again).

We also bought a Clipper Creek LCS 25 for portable L2 charging ($595). Cheaper than a new unit from EVSE upgrade and charges at 20 amps, so a little faster also. I fit this with an L6-20 plug and bought a couple of adapters from evseadapters.com so we can plug in at 240v outlets on the road.

hpver: Can you say whether of not the VersaCharge is suitable for occasional use in the same way as you intend to use the ClipperCreek -- they are both movable (although 20 lbs vs 9 lb respectively, I think)? This would allow you to charge at full speed, of course. You would need a 14-50p to 6-50r adapter for RV park charging at the commonly available 14-50r receptacles.

Either way there are safety issues that need to be considered, especially if using an EVSE outdoors in wet weather (like protecting the receptacle(s) from getting wet).

Edit update: I corrected typo above from "8-50r" to "6-50r".

The CS rep told me earlier they used to replace - but now they just change the max current (obviously the cheaper solution).

I just leased a Nissan Leaf 2013 SV. I can charge it at a Nissan Dealership down the street from my office in about 30 minutes, using one of the massive chargers, for free.
My wife just leased a Chevy Volt.

We think it makes sense to upgrade our chargers, if we can find a charger that is compatible with both cars.

What say the EVSE gurus?

Great forum and collaboration. Thank you. :D

All J-1772 charging stations are supposed to compatible with all the new plug-ins. There have been some reports of incompatibility with some EVSE or the other, so do a search before selecting the particular option.

The "massive charger" is a DC Quick Charge. It feeds high voltage electricity directly to the LEAF battery. The Volt is not designed to use anything like that. Both the Volt and the LEAF have chargers built in to the car which can accept either 120v AC or 240v AC electricity. Those chargers convert it to whatever voltage the battery needs.

At the end between the chargers (as defined in the previous paragraph) and the battery, the cars are different. At the end between the wall and the on-board chargers they are essentially the same. The same kinds of J1772 connectors are used to plug into the car and the same kinds of EVSEs are used between those connectors and the wall. The cars use the same voltages and can support the same amperages. You can't update the chargers inside either car, but you can use the same EVSE for both, whether mounted on the wall or built into a charging cable.

But I'm guessing that isn't what you meant when you said "upgrade our chargers". EVSEupgrade can upgrade either or both of your portable charging cables. The EVSE specs are different, as described on their website. But the end result is that with either one you get something back that can be used to charge either car. HOWEVER, upgrading the Volt's EVSE gives you one that no longer works at 120v, only at 240v. The upgraded LEAF EVSE works at both 120v and 240v.

I'm not famiiar with the VersaCharge unit or its outdoor capabilities. The Clipper Creek is nearly as compact and movable as the original L1 charger that came with the car, and it's both indoor and outdoor rated so OK for all but the worst outside conditions. The EVLink that we have is rated for inside, but we could take it with us also. I would be more careful putting this outside, and this would allow us to charge at the full 6.6 kw. That draws 30 amps continuously, which may be more than some outlets can handle. The unit has a sturdy plastic cover but it's not sealed. Plastic trash bag would protect it I think. Doable with some precautions.

Both units can plug into a 14-50r, or a 14-30r, which in my limited experience are pretty common at RV campgrounds and such. Can also plug in to a 10-30. Not sure why you would need an 8-50r adapter if you are going from a 14-50 p to a 14-50r.

hpver: Sorry, I meant 6-50r, not 8-50r (my eyes?). Also I don't know why I confused EVLink with VersaCharge, my apologies to you and Schneider! But thanks for your response to my ill-edit-checked post.

It seems to me that a very promising approach for a versatile yet safe portable EVSE would be one designed along the lines of the Tesla MC (Mobile Connector) for the Tesla Model S (and Tesla UMC (Universal Mobile Connector) for the Tesla Roadster). Unfortunately, those use a proprietary charge plug and not the J1772 plug (so can't be used by the Leaf), but hopefully a low cost version will be available to Leaf owners before too long.

The attractive idea to me is that multiple interchangeable input plugs be available to connect to the receptacle at hand and communicate to the control box what the appropriate maximum charge rate is for that receptacle. So for a Nema 5-15, the maximum rate to be signaled to the EV is 12a, for a Nema 10-30 or 14-30 maximum rate is 24a, and for a Nema 14-50 maximum rate is 40a, etc. This would allow for nearly foolproof amp selection for safety, and a compact design would make it easier to protect the receptacle/plug connection outdoors in wet weather.

BTW I've noticed a curious difference between the adapters available for the new Model S and the older Roadster: unlike the latter EV, the former does not (currently) provide an adapter for the Nema 5-20r receptacle. I'm speculating that Tesla may have decided that there are too many instances of homeowners replacing a 5-15 receptacle wired with 14 AWG wire with a 5-20 receptacle (possibly a GFCI type) and maybe even (shudder!) replacing the 15a overcurrent protection with a 20a one, not realizing it is a potentially serious safety hazard (and a code violation) to do so unless the outlet is wired with (at least) 12 AWG wire. This may also be the reason that appliances (including and especially portable EVSEs) rarely use a 5-20p plug (and draw more than 15 amps) -- it's too hazardous to casually use them on a 5-20r receptacle unless it has been carefully checked and determined to use 12 gauge wire and otherwise meet code!

Interesting info dated April 2013 I ran across concerning the EVLink EVSE and compatible EV inlets that may bear on some J1772 problems: "Schneider Electric™ EVlink charging station connectors (SAE J1772 plug) are for use on vehicles with an SAE J1772 compliant connector with silver plated contacts only."
