System 1 groups are normally smart to share something about their respective powertrains. In any case, there are massive benefits available beneath the hood, however now that powertrain improvement is frozen till 2026, Mercedes is giving us a really detailed take a look at how its hybrid system works. And this can be very attention-grabbing.
Like all the opposite groups' methods, the Mercedes drivetrain consists of a combustion engine, two electrical motors, a battery and a number of energy electronics. An engine is built-in into the turbocharger and harvests power from the exhaust. It could additionally present an instantaneous enhance to the engine so long as the battery accommodates sufficient power to take action. It's referred to as the MGU-H and might be passed by 2026. Apparently, it's very difficult to get proper, and F1 believes that the event of this half particularly has prevented automotive producers from becoming a member of the community as engine suppliers.
The opposite electrical motor is built-in with the gearbox. It could ship energy on to the rear wheels and harvest power when braking. This element is maintained as a part of the brand new rules.
These methods work along with the ability electronics and the battery, which is proven within the Mercedes video in unimaginable element. The battery pack itself consists of about 200 particular person cells, in all probability of the 21700 selection (so referred to as as a result of they’re 21mm in diameter and 70mm lengthy). They’re packaged in the identical case because the inverters and energy electronics, and the whole lot is cooled via a standard loop.
The video centered on this cooling loop, particularly as a result of Mercedes' important sponsor, Petronas, developed the coolant. It’s dielectric, which means that even when it leaked into the ability electronics, it could not trigger a brief circuit. Most of these insulating coolants are generally utilized in hybrid and electrical automobiles, however we will assume that the sort utilized in F1 is especially efficient.
General, that is an unprecedented take a look at the construction and dealing nature of an F1 hybrid system. If you happen to've ever been interested in how the whole lot works right down to the cooling loops, this can be a nice useful resource. Now if solely different groups put as a lot effort into exhibiting off their know-how. It could be fascinating to see how different producers remedy the identical issues.
