Re: Battery Charge/Save Buttons

As this involves so few miles the difference, even if you could accurately measure it, would be negligible and swamped by all the other variables of real world driving.

The only way Save could be more efficient is if you forget to come out of Charge at the right time and have "petrol" miles left you can't use :lol:

I completely agree with Greendwarf. Since CHARGE and SAVE are basically using the same method with the only difference of one being intermittent and the other constant the results in same conditions should be similar.
The small difference will be from the fact that usually SAVE is used with not empty battery and may be little bit more inefficient to maintain the charge instead of charging completely depleted battery.
I personally almost never use SAVE cause can't control the level of charge precisely (up or down charging in the moment I have to switch to EV) and don't want my ICE to come to life and off every couple of minutes.
On a long trip on flat roads were I know there isn't any congestion I run the battery flat and charge it back to 30%, rinse and repeat.

With your manual save mode tactic you could easily charge up to about 60% before rinsing the SOC back down. As I do it mostly on long trips this way. A higher battery level provide more range for slow speed areas like road buildings where it is nice not to hear the ICE.

I am doing that on my last leg of my trip in order to accumulate some charge for the city driving.
Yes I could charge up to 60% instead of 30% but by my understanding the battery is getting charged more efficiently in it's lower range of SOC.
Probably not even measurable but it doesn't hurt.

I can't find it now, but someone did some tests fairly recently charging the PHEV using the engine at idle. The rate was fairly constant up to 60% (actual), and it only started dropping off after that
