There are two very different ways the PUs and ES are used.saviour stivala wrote: ↑16 Jul 2018, 10:22As far as I know electrical power deployment can only be deployed by the “K” and not by the “PU”. Deploying 6-8 MJ per lap of electrical power, 4 MJ of which must be from the “ES” and the rest from the”H”, are conservative numbers compared to other numbers that have been banded about. However assuming that is correct, and on that lap the driver has managed to harvest by braking what is permitted, what happens on the next lap with a 50% charged “ES”?. If it is not qualifying, what sort of race strategy is that?. We had seen what happened with one of the red bulls when the driver said he had no deployment power left and he was told that he used it all.
I honestly don’t mean any disrespect to anybody, disagreeing does not mean that. I consider my knowledge as being able to just scratch the top of F1 matters, This being confirmed by being told that I risk being eaten up for breakfast by the more knowledgeable folks on here.
In qualification they start the qualification lap with 4MJ available in the ES, and they end the lap with zero. Using your assumptions they start at 8 and go down to 4.
In the race they try to start and end the lap with the same SOC. Let’s say 2MJ for the sake of this discussion.
In the case you quoted with Ricciardo a scenario might be he started the lap with 2MJ but ended it with 1MJ. He used a little more than he could recover. He was driving harder to try to catch or overtake. Now on the next lap(s) he needs to use less than he can recover to echarge the ES.
At Baku we saw Ricciardo spend several laps at a time charging his ES falling back from Verstappen a little, before launching an attack in which he intended to use most, if not all, of his ES to catch and pass. Once past he would have driven a little slower and defensively while the ES recharged.
You must now ask ourselves, if the ES can only be charged by braking how did Ricciardo brake much less than Verstappen without running off the track?
My answer is that he didn’t and that the MGU-H was used at the end of straights to send energy to the ES and not to the MGU-K.
Edit: fixed an auto correct although charming the ES is a nice idea
