What kind of proof I asked? Do publications in sciencedirect.com and ucsusa.org cout as proof or you need all the mathematics and physics behind it?ThudnBlundr wrote: ↑Tue Mar 23, 2021 10:47 amAnd still no proof! For proof we need to see actual figures, not theories. How do you know the ICE is more efficient in parallel mode on the highway to series mode around town? Any figures? What are the actual losses in Series and Parallel modes? Any figures? And it certainly isn't basic knowledge that an EV with an ICE is more efficient on a highway than in town - you're confusing the PHEV (an EV with regen and ICE optimisation) with a car driven solely by an ICE geared to the wheels. So you are proposing theories as fact - however plausible they may seem, you have nothing to back up those theories. Of course, if you do have any figures whatsoever to back up your claims, I'd be happy to be proved wrong.kpetrov wrote: ↑Tue Mar 23, 2021 5:58 amThudnBlundr,
What kind of scientific proof you may need? It is basic knowledge the ICE is more efficient on the highway than town, even more efficient when mechanically coupled with the wheels (which occur over the speed of 65km/h only) and electric propulsion is much more efficient in stop and go traffic compared to an ICE and when we include and losses from AC - DC conversions is getting even worse.
Which of those statements you refute? If you agree with them no further proof is needed.
Series vs Parallel vs Series/Parallel Drivetrains
Parallel drivetrains:Series hybrids perform at their best during stop-and-go traffic, where gasoline and diesel engines are inefficient. The vehicle’s computer can opt to power the motor with the battery pack only, saving the engine for situations where it’s more efficient.
A lot of publications here as well... sciencedirect.comSince the engine is connected directly to the wheels in parallel drivetrains, the inefficiency of converting mechanical power to electricity and back is eliminated, increasing the efficiency of these hybrids on the highway. This reduces, but does not eliminate, the efficiency benefits of having an electric motor and battery in stop-and-go traffic.
BTW basically I agree with everything you said to jpalfrey and it seems you know the vehicle. Why you need an proof regarding parallel vs. series when you already know it is beyond me.
