I see some ppl write that they use battery control to charge the battery's hole running the ICE. Why? This is rather inefficient and you end up spending more gas in the end. Iow, if you started with a full battery and max fuel, you would get further by not using battery control to charge the battery.
It is very inefficient . I only do it to have a fully charged battery during my trip to the alps. I can't charge here but I want to be able to pre heath. I is a bit less than 10% off battery charge each session to pre Heath. So I put my car on battery hold 30 min before I drive up the hills to the hotel to have 100% at the beginning of the week. And I put it on battery hold for the drives each day from the hotel to the slopes. I am at 16,5 l/100 km for this week. So very inefficient.
