Hello dear members,
My name is Sukru, living in Almere and a proud owner of a 2014 Nissan Leaf Tekna, well as of tomorrow 🙂
Driving an electric car will be a totally new experience for me. Now trying to figure out the potential challenges and how to eliminate them. Hopefully with your help it won’t be that challenging.
I would like to thank Edwin for creating this forum and also like the personal touch very much well. Feels like a community.
Thank you for the warm welcome Thijs!
The reason for English is, I am not fluent in Dutch [at least not yet 🙂 ] Though I can definitely try, if that would more appropriate.
Regarding my nick name, had no idea about the German meaning 🙂 learned something new.
I got the Leaf yesterday, brilliant car. It takes a bit of getting used to the absolute silent engine. All other external sounds feel like amplified.
The journey from the dealer to my home was an adventure ( from Groningen to Almere). The distance was a little over 150km, and range of the Leaf was a little shy of 130km. However, the wind yesterday in north was very strong. I could feel the resistance, so did the battery :). Had to charge 3 times to be on the safe side, maybe I was a little freaked out of getting stuck with no power (range anxiety at its best).
Anyways, I made it home just fine. Consumption was approximately 28.5 KW for 165 km. So 17KWh/100km.
It is a fun car, just requires a different way of driving 🙂
now my biggest topic to sort out is charging my car at home. Trying to weigh the pros/cons of the supplied charger via regular power socket vs. investing in a home charger.
Anyways, I’ll be on a business trip until Thursday coming week, will think about it after the trip.
Consuming only 17 kWh/100 km on highway with such headwinds is a nice job done.
All well and settled again? Or are you still blazing circles in your new Leaf because it drives like a thrill?
Concerning your home charging solution, I would strongly suggest to look into a rugged installation. A normal wall outlet (“Schuko”) (stopcontact) has not been designed for continuous loads of 10A or more. This doesn’t mean that problems need occur, but using something beyond design usually isn’t a good idea. If you want to use a (existing) outlet temporarily, make sure to test the plug after about one hour for getting hot. A bit warm is OK, hot is not OK.
If you want maximum flexibility for future at minimum cost, create a red CEE outlet at your outside wall and wire it to the junction box completely. The red CEE16 and CEE32 support three phases, whereas your current Leaf only takes one to charge. A future vehicle might be able to use two or three.
From the CEE socket you could connect a mobile charger either directly or using a red to blue CEE adapter cable (from three to one phase).
You might also acquire a (second hand) wallbox with fixed cable for maximum comfort. Now that first generation EV’s with type 1 plug are being replaced with younger type 2 plug EV’s you might be able to get a used wallbox with the type 1 cable you need, for nice prices.
Just back home from the business trip, anxious to play with my new toy 🙂
I have 1 phase power connection at home with 40A main circuit breaker. I have space in my junction box for an additional circuit breaker. I am thinking of installing a 32A circuit breaker with earth leakage switch (Aardlekautomaat?) with 6mm2 ground cable (L+N+E). What I don’t get is CEE 32A sockets are 4 or 5 poles and an adapter is giving me 16A output. Then what is the point of installing CEE 32A socket? Maybe I am missing something.
My advice is to connect a 5 core cable to your CEE Socket.
Because e if you later on maybey get to a CCS socket for 3-fase connection, you are prepaired for the future. ( 3-fase&Neutral+Earth. )
And remeber, if you like to use more then the regulair 10 Amp granny cable, you need a EVSE box to regulate the current bij the type 2 connector.
Then you are able to charge up to 6,6 kW (28 Ampère )
OK Sukru, you’re welcome!
Intention of my message was to instruct you to take no “half measures” and prevent you from having to do it again in a couple of years if you should acquire a new vehicle that could charge on multiple phases instead of just 1 – that’s all.
Your approach sounds good – keep us posted!
was very busy with work and at home as well hence couldn’t give an update on the electrical installation.
Well good news for me, it is done. I followed the advice of @Romulus and @jwgroene. Got a dedicated 32A circuit breaker, 4X6mm2+earth ground-cable and a CEE 32A wall socket installed outside. Also got a rubber cable mat since I don’t have my own drive way. Now I am able to charge my car at home and also have a future proof installation. All done by a certified electrician in exactly 2 hours 🙂
As of now this setup fulfils my needs and probably I won’t invest in an EVSE box. I have also applied to the municipality to have a public charging pole in my area, let’s see how it goes.
Next; I will post my experience with the car commuting to work and back, the battery condition and the range.
wish you all a great evening!
Thank you @Romulus
I have mixed feelings. I absolutely love the electric drive, though the range and the status of the battery not so sure.
I bought a second hand 4,5 years old, 26K on the counter. I can make (if driving very decent) 90km with 100% charged battery and will still have 3 bars left (app. 20-25% ?). Which I assume is OK. Then I checked the battery with Leaf Spy Pro and it shows 197 GIDs (70.1%) remaining. The battery indicator should have lost already 2 bars I presume, but no it still has 12 bars.
In any case despite what the dashboard shows and LeafSpy tells, based on a 110KM trip with a full charge, consumed 16.6 kWh and left with 13% charge the battery capacity is app. 19kWh. which means it lost app. 4,5% capacity per year.
So in 4-5 years I will end up with app. 15kWh capacity and my practical range will drop to 80 something kms.
I wonder if the battery cells are repairable when that time comes and would it cost a fortune?
I heard that there is Dutch company which is able to install 30kWh battery pack- which adds up to to the existing capacity- into the trunk. Sounds like a great option, can’t recall the company name though.
I understand your mixed feelings. But let’s start with measurements to make sure what we are talking about. It is good that you have LeafSpy Pro (LSP) and a dongle already.
The battery condition (remaining after degradation) is not the SOC (state of charge) but the state of health (SOH). If you read and document that one it will help you keeping track of the battery condition over time. Tendentially it will go down in summer and up in winter, by the way.
If you don’t drive with LSP, I suggest you keep an eye on the percentage counter on your dashboard to know charge remaining. It’s in the menu operated with the buttons at the left. Your 2014 should have it. The GOM (Guess-O-Meter) on the right hand side is way too coarse (bars) and too unreliable (km remaining) to stick conclusions to. See also http://www.electricvehiclewiki.com/wiki/battery-d1/
Individual battery cell replacement is technically possible but I did not yet hear about that being done in a commercial way.
The company you mean is probably Muxsan.
That’s right, the 70.1% I read on LSP is SOH. I wonder almost 30% loss in health/capacity in just 4-5 years is normal.
I have been keeping an eye on the battery % on my Leaf’s dash while driving. What I can say is 1% equals about 1.2km drive (give or take). i.e. this morning, 100% charge and drove 47kms, left 60% charge.
All in all, driving an electric car is real fun and green, just need to plan ahead- no room for surprises if you are driving a car with relatively limited range.
Hopefully in the next few years there will be commercial solutions more common and affordable to recover the lost capacity or even increase it (like Muxsan you mentioned).
If your 2014 Tekna really only has 70% SOH left, there should be at least three capacity digits missing (small bars outer right): http://www.electricvehiclewiki.com/wiki/battery-d1/#battery-capacity-behavior
That’s fairly much loss for a 2014: https://insideevs.com/nissan-leaf-30-kwh-battery-degrading-more-rapidly-than-24-kwh-pack/
If you can drive 1,2 km per percent of charge in winter time with this capacity loss then you either have a very favorable profile (downhill, city speeds, no head wind), you dislike heating and/or you are a very routined electric driver.
In short all informations you shared indicate to me quite a normal behaviour for a 2014 Leaf. Only the 70% SOH read with LSP doesn’t fit in. Are you sure?
And yes, it’s tedious by times… especially now that the number of electric cars is increasing and they all want to use the existing facilities.
I agree, based on the range I’ve been able to drive and also the consumption SOH displayed by the LSP doesn’t make sense.
If the battery % shown on the dash is reliable then I can make a basic calculation which should be accurate. Yesterday I started driving with 100% charged battery. At the end of the day the dash was showing 24% left. Based on the Nissan connect app data consumption was 14.7 kWh. So the capacity at present should be 19.34 kWh. If I take 24 kWh as the baseline then SOH would be 80.58%.
This sounds much more logical and accurate. However still doesn’t explain why my Tekna have 12 bars in the battery indicator on the dash. Shouldn’t be 10 by now?
