ALL ABOUT F1 BATTERIES
Mode charge On? Let's discover the F1 batteries with 12 years in F1.
1) The chargers
The batteries are charged by two principal systems.
a) The MGU-K | Motor Generator Unit-Kinetic | It is a system that recovers energy lost in braking.
b) The MGU-H | Motor Generator Unit-Heat | It recovers energy from the exhaust stream which the turbocharger doesn't need anymore.
That gives an overall system as such:
The battery is a Li-ion battery which can store and deploy energy in a considerably fast way. On its website Daimler suggests : "In F1, we’re now close to 1,000 volts with the ERS battery. Modern electric road cars usually operate systems of up to 400 volts; however, the voltage will increase in the future and be closer to the voltage used in Formula One today. "
It is placed as low as possible in the car to lower the center of gravity mainly because the battery is a heavy component. As we can see in this old but gold picture below
The deployment of the energy
Some of that energy is used to keep the compressor running so that there will be no turbo lag when the drivers goes back on the throttle. And some of it is applied to the wheels through the drivetrain to give approximately 160 more bhp.
The overall electrical system would be as such
