Overview


Framing Question:   How can we increase the travel range in EV for fixed battery capacity?


EV Power Optimization Project Proposal Summary

  • The proposal team aims to initiate and lead a dedicated EV power optimization Interest group within COVESA.
  • An initial seeding project aims at :
    • Develop standard specification for power optimization.
    • Demonstrate features/scenarios by POC.
