Does the DS7 E-tense have any feature to calculate actual electrical consumption when on electric or hybrid mode? Does it calculate separately the electrical consumption and gasoline consumption?
Finally, what kwh/100km do you usually get on average? I am in the process of evaluating my options whether the PHEV DS7 would be more cost efficient compare to a full hybrid (i.e. RAV4 or Renault Rafale)
Many thanks for the info in advance!
During current travel, you can see both fuel and battery consumption separated.
The battery usage disappears and is not saved when you turn off the car, but fuel consumption is saved to the app for each trip.
(edit: should note that mine is a 2020. Not sure how it looks on the newest models)
I might not be the best benchmark because I seem to have the worst battery mileage of most, for some odd reason, but in summertime it usually ends up between 20 and 30 kwh/100km when going to/from work.
What’s the difference between PHEV and full hybrid btw?
Thank you very much for the info.
Regarding your question, the full hybrid is self charging, meaning there is no need to plug therefore what you only need to calculate, when you evaluate i.e. your annual expenses, is the gasoline consumption. However, when you want to compare expenses between these two technologies, for the PHEV except the gasoline consumption, you will additionally need the electric consumption that is paid through electrical bills. Hope this clarifies your question
Oh, ok.
But I would probably reverse the terminology; the full hybrid is the plug-in and the one that is not plug-in is just a semi-hybrid (or half-hybrid).
The DS7 E-tense can also recharge itself, but just like with the semi-hybrids, there isn’t much efficiency or point to it. A tiny amount that comes from braking, sure, but other than that you’ll just end up with a higher fuel consumption.
A plug-in beats the non plug-ins every day of the week.
Based on my calculations, if you keep the electrical consumption at 20ish kwh/100kmm and you charge them on daily basis so that to optimize electric use, then yes, PHEV are more cost efficient. But if you go to 30s or if you skip some charges, then the advantage is almost lost in practice and annual expenses become quite similar. But that depends of course on each one’s driving pattern and these calculations just refer to mine :-).
Not sure if this is relevant to this thread but I’ve noticed on my DS4 E Tense that since I’ve been using the car in full electric mode more often and charging more often, the predicated mileage has gone from 22 miles @100% charge to 31 miles @ 100% charge.
I expect this to increase a bit more as I use the car in electric mode more and charge it more often ?
Not sure how you did them in that case.
But I guess it also depends on what you pay for electricity and fuel.
For me it’s still half the cost in electricity at 30 kwh.
But most importantly, non-plugins have nothing that plug-ins doesn’t.
So I can’t see how non-plugins ever would be more efficient.
Actually they do have some considerable differences and these are related to the core operation of each system. In short, Non Plug-in hybrids dont have such big batteries (instead of 15 kwh they have 1.5-2 kwh) and are constantly charged mostly by braking, which has been fully optimized for these systems (toyota, Honda and recently Renault do have really efficient systems), as well as during engine operation, but to much smaller extent. Therefore, when at city use, electric power is always available, mostly through braking recharge and for a considerable drive time (renault claims that 80% of city drive with their e-tech system is fully electrical). As for motorway drive, due to the smaller weight of the battery, non Plug-In hybrids carry much less weight, therefore engine may also consume less.
On the other hand, PHEVs do charge by braking, but to much smaller extent, as you already mention in your previous message, not because regenerative braking is not that efficient, but mostly due to the size of the battery. That is why, if battery is depleted, engine has to carry arnd 200 kg more, thus the increase in consumption, especially in city drive.
But if PHEVs are daily charged, then indeed their operation is much more efficient than self charged hybrids.
I don’t trust the app as it seems to have “interpreted” the figures it displays. I would look very closely at the number of journeys and distances you will be doing on purely electric and compare them with how many journeys and the distances you will be doing beyond electric range. I live at approximatley 185m and descend to sea level to go to the supermarket, a 22 mile (35km) round trip, in winter I get 2 miles (3.2km) per kwh and in summer 2.5 (4km). Once on the motorway and out of electricity I get 36 mpg (12l per 100km please check my maths) keeping up with the traffic at 70 mph. It works out at current prices if public chargers are more than 50p (58cents) per Kwh it is cheaper to burn petrol. Once every month to six weeks we do a 400 mile (640k) round trip and about 14,000 miles (22500k) per year. We should have bought a full electric or a straight petrol, both would have been cheaper over the lifetime of the car.
Same here,
Sorry I bought a PHEV, especially a DS , after the issues I’ve had.
Very seriously thinking of returning it as not fit for purpose.
In my case costs are 5.5€ electric vs 9€ petrol per 100km. Approx 3.2km/kwh @ 17c/kWh vs 6.5l/100km @ 1.42€/l
