Article C5.20.3
Battery Management System Requirements
Chapter: C5
In Simple Terms
Every F1 car's battery system must have a smart safety manager (BMS) that constantly watches for problems and can automatically reduce power or shut down the battery if something goes wrong. It also needs to keep all the individual battery cells balanced so they work evenly together.
- The BMS acts as a safety guardian, detecting faults and protecting the battery from unsafe operation
- If problems are detected, the system can reduce power output or completely shut down the ERS to prevent damage
- The BMS must actively balance battery cells to minimize voltage differences between them for optimal performance
- This ensures both driver safety and fair competition by preventing batteries from operating in dangerous conditions
Official FIA Text
The ES must be equipped with a BMS which: a. Must detect internal faults and must trigger power reduction delivered from/to the battery or shutdown the ERS if it considers that the ES is operating unsafely. b. Must be capable of reducing the voltage dispersion between each cell to its minimal level.
