There's nothing to stop you having that. Somewhere in this Forum somebody posted a picture of the Merc ES with a capacity label attached to it some time ago, which stated that the battery itself has about 8MJ capacity.godlameroso wrote: ↑Sat Aug 22, 2020 1:30 pmWhat is to stop someone from having a higher capacity battery? I guess I just need clarification. We have a 4MJ "bucket" for the ES, which is drained and filled throughout the lap. We also have a hard 4MJ limit per lap to the MGU-K. No such limit exists for the MGU-H.
We also know that state of charge is not the same as battery capacity. The state of charge on an electric car is probably the middle 70-80% of the battery pack's actual capacity. As that is where the battery is most efficient with regards to charging and discharging.
Wouldn't it benefit the MGU-H to have a higher capacity battery? Since energy flow to the MGU-H is unlimited, as long as you satisfy the SOC rule, wouldn't you want extra capacity for the MGU-H?
But the extra capacity isn't especially for the MGU-H.
The voltage is limited to 1000V in the rules, so the amount of battery cells you can use at any given moment is limted. But what you can do is cycle between them if you have more cells than you would need to simply reach the desired voltage. This is desirable because it makes cooling the battery much easier.
