Using Leaf Spy Pro to eek out the last few kms / Charge cost

Calahonda52

For family reasons, I am doing a 185 km one way drive.
I have it down to driving non stop at about 85 km/hr.
However, once I get to about 15 kms left the Leaf display just shows the three lines.
I drove it last night until GIDs were down to 3%, just wonder how far can I reduce the GIDS till I get the turtle.

In addition, I am using the granny cable for charging at the end which I need to pay for,
assuming am empty battery, what should I allow for the kWh draw:
its a 30KwH battery so what losses are there in the charging process.
Thanks as always

Low Battery warning 50 Gids (4kWh)
Very low battery warning 25 gids (2kWh)
Turtle (0.4kWh)

The above is what I got on the 24kWh Leaf. I believe the 30kWh Leaf is the same.

The Granny charger supplies about 2kW's to the battery and you have 28kWh usable so about 14hrs from 0-100%.

Thanks, so 28 kWh at what ever the cents per kWh is being charged on the bill?
say 20 cents so euro 5.60

Calahonda, i did 185km in my 30kwh leaf maybe two months at similiar speeds (on R roads) and got home with 10% battery IIRC just to give you a guide.

Ah, how much would it cost on a bill..... well 16c/kWh would be typical for daytime rate... and from 0-100 it would use 28kWh+10% for charger losses.... so about 31kWh@16c/kWh=~€5

Thanks, have being doing this trip since August and was getting home with c 10% left but last night I was later so lights and heating/air con were on, as well as wipers so was relying on Leaf Pro once the on screen display went to the _ _ _

The stress of that would do my head in. The what if's would have my nerves in tatters...

2kw for 14 hours continuously is a strong aul draw on a socket I'd imagine there's a fair bit of heat around the socket while that's going on.

Its 10A's. Sockets are rated for 13A so its fine unless the socket is already faulty and there is a bad connection with the pins... it might heat up then.

If you are using an extension lead and you keep it wound up that will heat up quite a bit and will eventually trip the extension lead. You are advised to unwind any extension leads.

Bear in mind, this is not the typical way to charge anyway... you should use a "proper" wall mounted EVSE which will have higher rated cable etc so over heating/tripping isn't an issue at all with those.

I know they're rated for 13 A but I think drawing 13A or 10A continuously for 14 hours isn't really what domestic sockets are designed for especially if at a relatives house and you don't know the condition of either the socket or the wiring. A lot of cheaper extension leads certainly wouldn't stand that continuous load for 14 hours whether it was coiled or not. If I make the plunge to an ev myself I would be using a wired in dedicated ev socket. It's just nice to know what size of current is involved with these cars.

Sockets are rated for 13A so that means it is designed for it. Lots of people use the granny charger only and they don't have issues. I used it myself for a few months before I got the proper EVSE and had no issues other than the extension lead tripping when I didn't unwind it.

I don't think there is an issue unless the socket is already damaged.... which I suppose is a possibility, particularly if its not your own house.

Thanks for all the insights here, on and off topic:D

Last Saturday I did a round trip from Nenagh to Malahide: 177 or so kms each way, in daylight.
First leg was no problem in the storm.
On the ay down I set the cruise control at the normal 93 (85 real) kmh.

Turned on the iPod and cruised away.

Normally the kms remaining on the screen is about 20 km greater than the distance to destination all the way down so so I took no notice.

I ignore the warnings: you may not be able to etc as it has worked fine all summer.

Very strong headwind, I happened to check the numbers just after Mayfield: the kms remaining was 15 less than kms to destination

Rather than stop at Roscrea or Obama Platz, I just dialled back the speed and eked it out down to 0.5kwh remaining.

Lesson learned. the poor CD factor in a headwind is a consumption issue that needs to be tracked on route if trying to max out the distance travelled.

You were cruising at 85km/h and then you dialled back the speed? You weren't in a hurry so

But on a serious note, do you not find that kind of speed so boring that it is borderline dangerous?

Mayfield and PortLaoise usually busy, especially P/L with a Gorey-esque type taxi driver.
Roscrea is 6km round trip from junction 22..
I did the Nenagh Dublin trip this am: left at 06:00 knowing I could get to work without a stop means a lot

As for boring, not at all, if you look at my profile you will see any speed above ground is welcome: podcasts, audio books, music.....

of course your car has a much better CD:)

I'm with you Cala.

I find the Leaf such a comfortable driving experience, I'm never in much rush to get anywhere. Throw on the tunes or podcasts, and saunter along.

Obviously I put the boot down when needed. But I try plan accordingly.

That doesn't sound like fun to me, you'd be quicker walking. Driving like that on a wet day sitting in the slow lane with all the lorries spraying muck and dirt all over me plus one eye continually watching the dwindling battery sounds like hell to me.

What makes you think there's traffic behind me?

Speed limit is a limit not a target.
Especially on a dual lane road.

unkel

I see at as the minimum target you should always stay well above :pac:

Certainly with the speedo in the leaf that's true

120km/h real world is actually between 128 and 130 on the speedo.

When not in a hurry , my motorway speed is 95 km/h in the leaf and 100 km/h in my 2.5L crew cab, both return a good balance between economy and speed.

At that speed trucks overtake you and pull away , so no issues with spray and serously faster then walking , the arrival difference for a 50 km motorway trip comparing 95 and 120 km/h is 6 minutes , big deal , an unexpected traffic conjestion at the start or end can blow that away.

Need to recook my phone with original firmware so how can I backup/restore the Leaf spy pro or am I done another XX euro?

That is on your Google account not your phone.
