Question about self charging hybrids

Stubod

The term "hybrid" or HEV is sufficient. "Self charging" suggests it magics the charge out of thin air. It doesn't, it gets all its electric charge from the petrol put in.

...not quite, it charges the battery when going down hill / using "braking". More than happy with mine....

And how does the car get to the top of the hill in the first place? By using petrol. So, yes, although there is an extra step, it does only charge using the petrol. The only benefit (other than increased efficiency at low speeds using the electric motor) is that it wastes less energy than a pure ICE.

It really doesn't, unless you've discovered the rarest of roads that's downhill in both directions 

Recharging from the ICE (at 20% efficiency, 8.9kWh/litre --> more than 80p per kWh) isn't cheap.

The saving comes from the fact that the hybrid has a couple more options in terms of energy management than a conventional ICE which is essentially just a giant fireplace on wheels that occasionally spits out a bit of kinetic energy now and again.

I suppose it comes down to the op,s requirement’s if you regularly pound up and down the motorway then diesel is probably best, my previous car was a mild hybrid, which used an electric motor to assist the engine, on motorway trips on holidays I could get 61mpg with steady driving , I switched to a self charging hybrid when I changed my car last year, I travel an eighteen mile round trip each day to work and back, in the summer I saw 68/ 70 mpg ( according to the trip computer) plus usage at the weekends, it does , however, take a hit in the winter, seeing it fall to around 54/5 which is still good, now it’s warmed up a bit it’s back up to around 60 mpg, I’ve not been on any motorways with it as yet but a trip last year to the lakes saw 65ish , it will run in pure electric mode at speeds up to the mid 50mph, and in theory, it can go up to 70 mph in electric, I think , in my case, a self charging hybrid is the mid point from ice to full electric, but, until the prices drop and the range increases,plus the charging infrastructure is improved, I’ll hold off..

Our diesel got 44mpg.  Our hybrid can get 60+ mpg.  Our EV gets 300+ mpg.  I don't see that as quite the mid point, but it is a significant saving over a diesel.

That's nice, you have a house and driveway, smart meters and are paying 7.5p kwh overnight from Octopus.

Yes or No.

Must be yes as there is no other way to get 300+ miles for the price of a gallon.

My friend has done much better 10k miles for FREE, No mpg cost.

Drops it at sainsbury's at 06.00am and plugs it in their free 7kw charger.

Gets on the train to work.

Wife walks kids to school and picks up car at 09.45am.

I'm on the third floor, no drive, no charger possible.

At todays prices, buy the car petrol and run for 20 year on the 10k saving from ev price.

I still win.

Because I will be dead by then.

It’s not a unique problem. Honestly I am surprised no-one has thought to tackle this because there is a huge untapped potential if only you could take your household rate with you +10%.

That would be a fair charge, no pun intended.

Done via a loyality card or such. Like shopping.

Imagine if Toyota had of put full EV tech into their Prius's many years ago. Those EVs would be all over the place now. A Prius EV would be as efficient as a Tesla Model 3 and the company would be in much better shape, probably as big as Tesla. Kia and Hyundai where successful in making EVs along side Hybrids so it could have been done.
Toyota have seriosly got it wrong. Their Hybrids are good but their EV Prius would have blown the market away, they would easily achieve 5 MPKW with this aerodynamics. Instead they have their over priced BZX4 about 5 years too late, its almost as if they don't want to make EVs.

Maybe Toyota are ahead of the curve and don't see pure EV as a long term global solution for their business.
