Safety changes are on the way from Formula E’s battery provider after a scary fire halted the Valencia test last month
Formula E’s battery suppliers, Williams Advanced Engineering, will be implementing safety changes following a test fire at Valencia. The investigation report revealed that a contactor caused the initial issue that stranded Shwartzman’s car on track. New contactors will be fitted to all RESS units used by teams, and new protocols regarding contactor temperatures and safety limits will be established. Additionally, improvements will be made to the battery management system protection, allowing for easier detection of communication loss. Long-term changes include factory-based RESS testing and a specific pass/fail threshold for contactor temperatures. These changes will be implemented for the first round of the championship in Mexico City in January.
