On top of this, it is critical to design cars that strike the optimalEngineering the optimal battery thermal balance between conflicting attributesmanagement system design and like comfort, driving pleasure,architecture while balancing costs, range, performance and durability. thermal comfort and durability is a critical task. Decisions must be made considering To cope with these challenging designnot only thermal safety and its impact on requirements, OEMs need to adapt todurability, but also on range and new development priorities and build anperformance, cabin comfort and battery engineering organization mappedtemperature.
