ERS-K Absolute Electrical Power

In Simple Terms

The ERS-K (kinetic energy recovery system) is the hybrid power unit that harvests energy from braking. F1 regulations cap the maximum electrical power this system can produce at 350kW to maintain competitive balance and prevent any team from gaining an unfair advantage through excessive hybrid power.

• ERS-K electrical power output is strictly limited to a maximum of 350kW
• This applies to the absolute DC electrical power measurement of the kinetic energy recovery system
• The limit ensures all teams operate within equal technical parameters for the hybrid system
• Exceeding this power threshold would constitute a technical regulation breach
