ERS Components in Hybrid Units
Motor Generator Units
In today's hybrid Energy Recovery Systems (ERS), two motor generator units play a key role. The MGU-K (Motor Generator Unit - Kinetic) captures energy during braking and can deliver up to 160 horsepower (120 kW). This makes it a critical component for energy recovery and performance enhancement.
The MGU-H (Motor Generator Unit - Heat), on the other hand, is connected to the turbocharger shaft and operates continuously. Its software performs several tasks: converting exhaust heat into electricity, controlling the turbocharger shaft speed to minimize turbo lag, and ensuring efficient power distribution.
| Function | Software Control | Performance Impact |
|---|---|---|
| Energy Recovery | Converts exhaust heat to electricity | Powers the MGU-K or charges the battery |
| Turbo Management | Regulates turbo shaft speed | Reduces turbo lag |
| Power Distribution | Manages energy routing | Optimizes energy delivery timing |
Power Storage Systems
Once energy is captured by the motor generator units, efficient storage becomes essential to ensure consistent power delivery. Modern ERS systems rely on lithium-ion battery packs, which are managed by sophisticated Energy Storage (ES) controllers. These controllers use advanced algorithms to regulate the flow of energy between components while adhering to strict technical regulations.
One standout feature of the ES controller is its ability to adapt energy routing based on race conditions. For example, it can transfer energy directly from the MGU-H to the MGU-K during high-demand moments, minimizing energy conversion losses and ensuring peak performance.
Temperature Control
Managing temperature is another vital aspect of ERS functionality. Predictive thermal modeling helps maintain components within their optimal operating range. Software algorithms dynamically adjust energy recovery rates based on real-time temperature data, ensuring the system remains efficient under varying conditions.
The system takes into account several factors, including the thermal state of components, track-specific cooling needs, ambient temperatures, and power deployment strategies. This precise approach to temperature management not only improves reliability but also ensures the ERS operates at peak efficiency throughout a race.
Software Energy Management
Energy Prediction Systems
Using advanced algorithms, energy prediction systems analyze real-time sensor data to optimize energy recovery, particularly in braking zones. These systems calculate the perfect balance between mechanical braking and energy recovery via the MGU-K (Motor Generator Unit-Kinetic). Several key factors influence this calculation:
| Parameter | Software Analysis | Impact on Recovery |
|---|---|---|
| Vehicle Speed | Tracks real-time velocity | Determines how much energy can be recovered. |
| Battery State | Monitors charge and temperature | Adjusts recovery rates to prevent overheating or overcharging. |
| Track Position | Uses GPS-based location data | Prepares for upcoming corners to maximize efficiency. |
| Weather Conditions | Relies on environmental sensors | Adapts recovery to conditions like rain or extreme heat. |
By combining these inputs, the software provides predictive insights that allow for dynamic, in-race energy adjustments.
Live Power Distribution
The Electronic Control Unit (ECU) plays a critical role in managing power distribution between the combustion engine and the electric systems in real time. This system ensures a seamless balance of power output while staying within regulatory limits, such as the 161 hp (120 kW) cap on ERS power output. Drivers can select from pre-programmed power maps, which adapt the ERS response to throttle inputs. This flexibility allows for strategic adjustments based on the race phase, whether focusing on acceleration, overtaking, or conserving fuel. The real-time coordination between software and hardware gives the hybrid unit a competitive advantage on the track.
Performance Results
The enhanced ERS software translates directly into better performance, boosting acceleration and improving fuel efficiency during key moments in a race. Whether it's powering through acceleration zones, executing overtakes, defending positions, or conserving fuel, the system delivers tangible benefits. Tools like AWS's "Hybrid Energy System" graphics provide teams with detailed lap-by-lap data on electrical energy usage. This visualization helps teams fine-tune their energy deployment strategies while offering a clear picture of the system's overall performance.

Race Performance
In Formula One, ERS (Energy Recovery System) software plays a pivotal role in shaping race outcomes by managing energy deployment during key moments. Teams fine-tune their software settings based on specific race phases to maximize performance:
| Race Phase | ERS Strategy | Software Configuration |
|---|---|---|
| Qualifying | Maximum Attack | Focuses on full power deployment to achieve the fastest lap times. |
| Race Start | Race Start | Delivers concentrated power for rapid acceleration off the grid. |
| Overtaking | Tactical Boost | Reserves energy for decisive passing opportunities. |
| Defense | Defense | Balances power usage to maintain position against challengers. |
Track-Specific Settings
ERS software isn't a one-size-fits-all solution - it adapts to the unique demands of each circuit. Track characteristics, like layout and conditions, shape how energy is recovered and deployed.
Take high-speed circuits, such as Monza, for example:
- Energy is deployed strategically on long straights.
- Recovery is maximized in the few braking zones available.
- Software is tuned to maintain consistent performance at high speeds.
On the other hand, technical circuits like Monaco demand a different approach:
- Rapid acceleration is optimized for exiting tight corners.
- Frequent braking points are leveraged for efficient energy recovery.
- Power delivery is carefully controlled to ensure precise traction.
Modern ERS systems now allow energy to flow directly between the MGU-K (Motor Generator Unit - Kinetic) and MGU-H (Motor Generator Unit - Heat), bypassing the battery. This minimizes conversion losses and improves efficiency. Environmental factors also come into play - at high-altitude tracks like Mexico City, where thinner air reduces engine performance, teams adjust ERS deployment to compensate.
What’s more, today’s ERS software uses predictive algorithms that analyze GPS data, historical performance, and real-time metrics. This enables dynamic energy management that adapts to evolving race conditions, competitor strategies, and even tire wear. By doing so, ERS software has become an indispensable tool for maintaining a competitive edge in Formula One.
