EVs - Real World Efficiency
ฝัง
- เผยแพร่เมื่อ 25 มิ.ย. 2024
- This week I reveal the results of a year-long experiment - measuring the average efficiency of my Renault ZOE. Along the way, we'll see what that means in terms of the real-world emissions of the ZOE based on my own driving data.
This is the latest in a series of videos sharing my knowledge and experience with electric cars. EVs have improved immensely over the last few years, and we are at a point where I think the majority of people can make the switch to electric.

The aim of my channel is to provide knowledge and plain speaking about the transition we all face. I hope you will join me for other videos on the move towards a renewable energy future. I will be covering plenty more about EVs, but will also be sharing my experiences as I look into energy generation and electric heating. - ยานยนต์และพาหนะ

Love these completely nerdy videos! 👍
That's lucky! Im glad you enjoyed it ☺️
As usual outstanding data analysis
Thank you. I'm glad you managed to make it through!
Thank you for the work involved in the making of this video. Even after another fossil fuelled weekend (motorbike) visit to the wonderful nurburgring , im grateful for this in depth information re lifespan emissions 😊.
Thank you. I hope you had fun - and that everyone was safe.
Great work. I'm not so concerned about life cycle emissions, I'm more concerned with walking down the street inhaling tailpipe emissions. I see the reduced CO2 emissions as a side benefit and catalyst for other industries to clean themselves up.
This is what we should focus on more. Otherwise we get the ‘greenie’ or ‘EVs wont save the planet’…if that is true we still dont have to breathe in the emissions.
Yes, that's a good point. That helps too. And, indeed, this subject might perhaps feature in a video on the channel surprisingly soon!
@ObiePaddles yes, I know exactly what you mean. Although, to be honest, people are going to be defensive - understandably - no matter how we approach the subject. I think, often, that's probably what brings about the attempt to dismiss the argument in that particular way.
@@theelectrictransition I think the cleaner air should be the first approach, it requires less thought by the anti-brigade because most of them are in the position of they don't know enough to know they don't know enough about CO2 and its effects on climate.
Brilliant great research thanks
Thank you :-)
OK by the end you cover everything well done.
Thank you. I may take my time to discuss an issue, but hopefully I get there eventually!
This is perfect, showing just how good the Zoe R135 is in the real world.
I would however check your winter range as I think “worst of 260” may in reality be in-fact 160. This would pretty much be similar to my own experience with our Zoe although mine was 152 over the last winter on full charge….. ah! Just played back and seen an update 👍
Yes, sorry about the confusion. It's been a very complex video to make, and I spotted the mis-speak too late to reshoot that bit. 165 is what I meant. I haven't seen anything in the 150s, but it does vary by usage pattern
@@theelectrictransition ..given the work that went into this project it’s entirely understandable.
The 152 indicated range as a matter of interest, was as a result of a longer period than usual of local short runs in a particularly cold period (-5 and lower). The guessometer suggested 152 prior to a trip we planned of 174 miles. Once we had set off, the steady motorway journey actually achieved the distance with the turtle mode just indicated before arrival and 7 miles range still on the guessometer. I admit it was with B mode and eco engaged and some carefully planned driving. I frequently find the indicated distance is increased when driving longer journeys as the battery ‘warms up’ after a period of short trips locally in almost all conditions including 20’ temps plus. Best actual achievement was 232 miles with 37 miles still indicated last summer.
Big thumbs up for your work. 👍
Thanks for the extra information, and the kind words.
You seem to be a master of economy, those are once again some impressive figures.
I agree, ZOE can tend to be a little pessimistic at the start of a journey. I totally understand that, though. It's got to be better to be pessimistic and then over-deliver, than to lull someone into a false sense of security and end up with them stranded somewhere.
I did think the 152 figure might have been triggered by the usage pattern beforehand. It does seem to vary its estimate quite a bit based on recent driving activity. I've had the same sort of behaviour several times. Generally my driving style and trip type don't vary much, but when they do I have definitely spotted a bit of mid-journey correction going on.
Well done, good to see someone who into electrical cars and the like, actually doing a real world analysis and not hoding any information.
I like solar electric cars etc but i hate it when companies or other channels present half truths or misleading information to try and push a set agenda or product as it just makes the opposition validated.
I agree. It's not helpful to be very biased or pushing a corporate agenda. I try to avoid both - although human biases are more difficult to overcome, so I may not always achieve it.
@@theelectrictransition you done very well in this one good job!
A real easy way to think of evs is where they get their energy from for driving. I think that getting the energy directly from the grid seems better than go the long way. Getting the petrol to the pump takes a lot of energy.
From getting the oil of the ground, refine it and transport it to the pump. And then only use about 25-30% of the energy in the petrol.
And a good point many makes is the air as such. We don't need pollution from the tail pipe. Another thing is the actual pollution from an average ICE car.
Cold start as every ICE car does and there is no filter, cat or anything holding the pollution back until the engine and everything isreally warm and that takes time.
For me it's obvious just by thinking of it that an ev in the long run i better. Think of everything about batteris that gets better year by year. An ICE car is what it is and can't really be better.
Yes, absolutely. We're probably at the pinnacle of ICE development, but still reasonably early in the cycle of improvements for EVs. Exciting times.
@@theelectrictransition Exciting indeed!
During production, emissions can be easily managed compared to products in customer hands
They can, that's true. It doesn't mean that they will. However, we could definitely "encourage" that through a bit of legislation, or perhaps some carefully guided market forces, akin to Euro NCAP
Why do you think the Zoe will only last to 120k miles?
A very good point. I decided not to talk about that in this one - but yeah, a longer life will only strengthen the argument, for sure
With renewable energy, EVs become completely emissions free
After manufacturing, yes. Or at least almost entirely, as at the moment, the installation of renewables does generate some CO2 as well. We tend to amortise the installation CO2 across energy generation, so nothing is quite zero yet.
I don't disagree with your point, though. Renewables trend towards a future of zero emissions very quickly, and absolutely nothing else does. Roll on renewables and their use for everything, including manufacturing and the installation of other renewables!
Your ice to ev comparison is very kind to ice cars. Comparing a zoe to a smart car is not very fair to evs.
Yes, absolutely right. I did it partially because this is my real world situation, but also because I don't want people to be distracted by bias in the other direction. I think it helps the conversation with sceptics - my target audience - if I can avoid being accused of bias towards EVs upfront
