In Formula One, battery power plays a crucial role in powering the cars. It is an essential component of the hybrid powertrain system that provides the energy needed to propel the car.

How Battery Power Works in F1

In this article, we will take a closer look at how battery power works in F1 and the technology behind it.

1. The Battery Pack

The battery pack is the heart of the hybrid powertrain system. It stores the electrical energy that is generated during braking and provides the necessary power to the electric motor. The battery pack used in Formula One is a Lithium-ion battery, which is widely used in consumer electronics and electric vehicles. These batteries are preferred over other types of batteries because of their high energy density, long life, and fast charging capability.

The battery pack is located in the cockpit of the car, behind the driver’s seat. It is a sealed unit that contains numerous cells, each capable of storing electrical energy. The number of cells in the battery pack varies depending on the manufacturer, but it usually ranges from 20 to 30 cells.

The battery pack has several safety features to prevent overcharging or over-discharging, which can damage the cells. The battery management system (BMS) monitors the state of the battery and regulates the charge and discharge rate to prevent damage.

2. The Motor Generator Unit-Kinetic (MGU-K)

The Motor Generator Unit-Kinetic (MGU-K) is a device that converts the kinetic energy generated during braking into electrical energy that can be stored in the battery pack. When the driver brakes, the kinetic energy is converted into electrical energy and sent to the battery pack.

The MGU-K also serves as a generator that provides additional power to the electric motor when needed. It is connected to the crankshaft of the engine and uses the rotational energy to generate electrical energy. This electrical energy is used to power the electric motor, providing an additional boost of power to the car.

The MGU-K is limited to a maximum power output of 120 kW (161 hp) and a maximum speed of 50,000 RPM. It is also limited to a maximum energy recovery rate of 2 MJ per lap. This is to ensure that the cars do not exceed the power and energy limits set by the regulations.

3. The Motor Generator Unit-Heat (MGU-H)

The Motor Generator Unit-Heat (MGU-H) is another device that generates electrical energy but uses the heat generated by the exhaust gases instead of kinetic energy. The MGU-H is connected to the turbocharger of the engine and uses the waste heat from the exhaust gases to generate electrical energy.

The electrical energy generated by the MGU-H is sent to the battery pack or used to power the electric motor. It is also used to power the compressor of the turbocharger, reducing the turbo lag and providing an instant boost of power.

The MGU-H is not limited to a maximum power output or speed, but it is limited to a maximum energy recovery rate of 4 MJ per lap.

This is to ensure that the cars do not exceed the power and energy limits set by the regulations.

4. The Electric Motor

The electric motor is the device that converts electrical energy into mechanical energy to propel the car.

It is located between the engine and the gearbox and is connected to the crankshaft of the engine.

The electric motor is capable of providing an additional power output of 120 kW (161 hp) for a maximum of 33 seconds per lap.

The electric motor is also used to power the car during the pit lane, eliminating the need for the engine to idle. This reduces the fuel consumption and emissions during the pit stops.

How Do F1 Drivers Charge Battery?

F1 drivers do not charge the battery pack in their cars directly. Instead, the battery pack is charged through the energy recovery system that is built into the hybrid powertrain system.

The Motor Generator Unit-Kinetic (MGU-K) is responsible for recovering the kinetic energy generated during braking and converting it into electrical energy. This electrical energy is then sent to the battery pack, where it is stored for later use.

The Motor Generator Unit-Heat (MGU-H) also contributes to the charging of the battery pack. It uses the waste heat generated by the exhaust gases to generate electrical energy, which is also sent to the battery pack.

The battery pack is charged constantly throughout the race, as the MGU-K and MGU-H are always recovering energy and sending it to the battery pack. The battery management system (BMS) monitors the state of the battery and regulates the charge and discharge rate to prevent damage and ensure that the battery is always charged to the optimum level.

It’s worth noting that the battery pack is not charged before the race, and the teams do not have access to any external charging sources during the race. This means that the teams have to manage the energy levels in the battery pack carefully throughout the race to ensure that they have enough power to complete the race.

In summary, F1 drivers do not charge the battery pack directly. The battery pack is charged through the energy recovery system that is built into the hybrid powertrain system, which recovers energy from the MGU-K and MGU-H and sends it to the battery pack for storage. The battery pack is charged constantly throughout the race, and the teams have to manage the energy levels carefully to ensure that they have enough power to complete the race.

What Does It Mean to Charge the Battery in F1?

In the context of Formula One, the term “charging the battery” does not refer to the traditional process of plugging in a charger to an external power source to restore the battery’s charge. Instead, the battery in an F1 car is charged through the car’s energy recovery system, which captures the kinetic and thermal energy generated by the car during braking and acceleration and converts it into electrical energy to store in the battery.

When an F1 car’s MGU-K (Motor Generator Unit-Kinetic) and MGU-H (Motor Generator Unit-Heat) units recover energy, they send it to the battery pack to store. This charging process is constant and happens throughout the race. The energy recovery system, along with the battery management system, regulates the charging and discharging of the battery to ensure that it operates at peak performance and is never overcharged or undercharged.

The battery’s state of charge is an essential parameter that F1 teams monitor during a race.

The battery’s energy level directly impacts the car’s performance and can affect the driver’s strategy.

Teams must balance the amount of energy that they recover and store in the battery with the amount of energy that they use to power the car’s electric motor. If the battery is too low on energy, the driver may not have access to the full power output of the car’s hybrid powertrain system. On the other hand, if the battery is overcharged, it can cause damage to the battery and impact the car’s performance.

To summarize, in F1, charging the battery does not involve plugging in the battery to an external source. Instead, the battery is charged through the car’s energy recovery system, which converts the kinetic and thermal energy generated during braking and acceleration into electrical energy to store in the battery. The battery’s state of charge is an important parameter that F1 teams monitor closely, as it directly affects the car’s performance and the driver’s strategy during a race.

Are the F1 Cars Running on Fuel or Batteries?

F1 cars are powered by a combination of fuel and batteries. The fuel is used to power the internal combustion engine, while the batteries power the electric motor that is integrated into the car’s hybrid powertrain system.

The internal combustion engine in an F1 car is a highly specialized, high-performance engine that is designed to deliver maximum power output while consuming the least amount of fuel possible. The engine runs on a specialized fuel called “Petronas Primax,” which is a blend of gasoline and other chemicals that are optimized for high-performance racing.

The batteries in an F1 car are used to power the car’s electric motor, which is integrated into the car’s hybrid powertrain system. The motor generator unit-kinetic (MGU-K) is responsible for recovering kinetic energy generated during braking and converting it into electrical energy. The motor generator unit-heat (MGU-H) uses the waste heat generated by the exhaust gases to generate electrical energy as well. The electrical energy generated by both the MGU-K and MGU-H is sent to the battery pack, where it is stored for later use.

The stored electrical energy in the battery pack can then be used to provide an additional power boost to the car when needed. The driver can use this additional power to overtake other cars or defend their position, but this extra power is limited, and the driver must use it wisely to ensure that they do not exceed the power and energy limits set by the regulations.
