Is there any way that the 'other' part of the battery is connected directly to the 'store' only, so although it is passed and used by the main unit it is not cLaserguru wrote: ↑Fri Aug 10, 2018 5:20 pmMGU-H can send as much power as it wants to the MGU-K as long as it goes through the MGU control unit (which has a maximum storage of 5KJ).
Assume Magneti Marelli's MGUH produces 90kW.
When thinking of a twin battery, as Ferrari seems to do according to FIA, you could imagine the MGU control unit as a secondary battery. So one big battery of 4MJ and a small one of 5KJ which is not called a battery (loophole).
MGUK energy to battery is max 2MJ per lap.
Battery energy to MGUK is max 4MJ per lap.
MGUH energy to MGUK is unlimited but must go through the MGU control unit.
MGUH energy to battery is unlimeted in both directions.
Maximum 120kW (160bhp) energy deployment limit between the MGU-K and the internal combustion engine. Full throttle for 4MJ/120kW=33.333s and your battery is depleted.
At any time the battery is fully charged with 4MJ you can harvest/store/deploy 5kJ from the MGUH through the MGU control unit ‘battery’ to the MGUK.
A propulsion boost of arbitrary 40bhp or 30kW is possible during 5kJ/30kW=167ms. It takes the MGUH 5KJ/90KW=56ms to harvest the excess energy.
This can be done at any circuit where you can harvest more than 2MJ per lap by MGUK and 2MJ by MGUH. Excess of 2MJ MGUH can be used in bits of 5kJ.
Imagine there are many corners and harvesting is plenty, every heavy breaking corner after lift and coast (battery 4MJ) you may ‘store’ MGUH energy in the MGU control unit for a whopping 167ms lasting 40bhp, deployed when accelerating out of a corner onto the straight. What does 40bhp for 167ms bring? A few kmh extra top speed? Faster acceleration out of the corners? Would be only a software update.
classed as being above the limit?
If the maximum the 'store' in the control module is set, can they perhaps say, look, its from there and you have already measured it once?
This would be more of a temporary holding option than an extra shot, but stored at parts of the lap it could not be used anyway
