Re: Nissan Tests 48-kWh LEAF

Thu Mar 26, 2015 3:44 pm

I suggest that Nissan, in addition to the Chademo port, add a CCS combo L2/DCQC port (instead of just the standard J1772 L2) to the next Leaf version. That way, the new Leaf will be able to charge with a standard J1772 L2 and at DCQC chargers (both standards, CSS combo and Chademo). From the images below, it sure looks like there is room in front for the current J1772 L2 and Chademo, so why not convert the current J1772 L2 into the CSS combo plug? Is this possible? I have no idea, but with the proper programming, why not? Think about it, with a 48 KWh battery and the possibility of charging at 50 KW with either CSS combo or Chademo, the Leaf would be able to access charging at almost every station in the country (except Tesla). I could even travel from Pasco to Seattle, with a 1-hr meal in Ellensburg or Wenatchee (which I typically plan for anyway with my gasser). In such a case, my typical 250 mi trip would take the same amount of time as the gasser, with a much better EV experience. Go Nissan! Now is your chance to wow all of us.

One virtue of having only one DCQC-capable inlet connector is that its contacts are kept safely hidden whenever a cord is mated into it. If you provided two connectors with DCQC capability, there'd have to be another rather expensive high-voltage relay to select between them.

A FAR better use for such a relay would be to provide the ability to connect either the motor terminals or the AC powerline to an improved-capability power conversion module that could then either charge the battery from the AC line or regenerated AC from the motor, or generate AC signals to either power the motor or drive out into the AC line.

Never underestimate the power of mechanical solutions as well. Perhaps they could design a connector that combines CCS and CHAdeMO, but locks out the CHAdeMO when the CCS is opened, and vice-versa.

I'd be surprised to see a SL or SV level 48kWh leaf with anything less than a 9.6KW charger. That'd be 45a @ 208v or 40a @ 240v. Plenty fast enough for home and destination charging. Even if they wimp out and limit it to 40a @ 208 you'd get 8.3KW charging on the road.

I would expect the cheaper S trim would have the old 6.6kW / 6.0kW charger left over from the old configs and no fast charging port included (pay extra for an optional one or force you to step up to the SV). Heck maybe the S trim sticks you with the old 24kWh pack too.

I can't see any scenario where they pair the old 3.8kW / 3.3KW charger with the 48kWh battery.

Keep in mind the Jamp JR evse options and you'll have an idea what you can pair up with a likely Gen 2 Leaf

JAMP JR

16 amps (3.8kW) Model 16-20 w/NEMA L6-20P
24 amps (5.8kW) Model 24-30 w/NEMA L6-30P
32 amps (7.7kW) Model 32-40 w/NEMA 14-50P
40 amps (9.6kW) Model 40-50 w/NEMA 14-50P

You already need a 30a EVSE at home to do the 27.5a the 6.x KW charger does on the old leaf. It only makes sense they'll step it up and make use of most or all of the 40a you can get from a 14-50 socket.

30 amps should be plenty. Anyone who isn't home for at least six hours a night is probably out doing something they shouldn't be and wouldn't be interested in an EV anyway.

48kWh battery would give you more range than a Model S 40kWh* which means road trips. You'd want to be able to charge to full overnight and want to charge as fast as possible on L2 anywhere you can't find a L3 option.

Heaven forbid you aren't there a full 7.x hours to charge on a hotel charger with only 30a @ 208v giving you 6.2KW. An extra 10 amps shaves 2 hours off the full charge time which might matter on a family trip where you have to beat traffic, meet others at a specific time, or make a start time at a destination event (movie, tour, boat launch, etcetera).

Besides when you get into the price range the 48kWh battery pushes you into people get super demanding about convenience even if it isn't purely logical to do so.

*While rare the Model S40 is good for 140-160 miles at worse efficiency than a Leaf. (EPA rated for 139 miles and no supercharging).

for on road units

average in home is 40amp.

Sun country is the usual suplier of the evse, and so far from bc to sask, all have been 90Amp rated.
The charge stations that Sun Country Highways is using are manufactured in California by Clipper Creek.

All their models refer to the CIRCUIT BREAKER SIZE, not the amps supplied to your car. That value is 80% of the circuit breaker size. We use both values in our model designations for our charge stations:

JAMP JR
Model 16-20 (16 amps to your car, on a 20 amp circuit)
Model 24-30
Model 32-40
Model 40-50

JAMP SR
Model 48-60
Model 56-70
Model 64-80
Model 72-90
Model 80-100

The J1772 (Tyoe 1 in Europe) standard for the world is between 6 and 30 amps, except the USA / Canada, which is 6 to 80 amps maximum (courtesy of Tesla's petition to SAE).

hen most are at their max rated as I said befor, here we wanted future proofing so they just installed the largest they could, so at worst 70A dilivered at average of 240v, some at 208.

As some one with a great amount of electrical experiance I do know the difference between breaker and suplied, in the case of the 90Amps I took the instalers word for it, but then was pointed out he was in error, he should have stated 90A breaker at 80 Suply to the vehicle, I can forgive him on his error.

point was and still is right this second Nissan can really gain by puting in a larger charger now, and then when the 48KwH Version comes to play they will have gained more market share and credibility as a practical functional car!
2013 SV Leaf, Level 2 charger, so far all works great! 130Km daily, 100% charge at night on 240 then trickle charge for 8H durring the day on 120v.

Level 2 charge starts at 130am environmental starts at 6am to 25c for a toasty warm defrosted car!
