Effective thermal management is essential for the performance, efficiency and reliability of electrified off-highway vehicles. This presentation will explore the critical components and subsystems that require thermal regulation, including batteries, electric motors, power electronics, hydraulics and operator cabins. It will provide a comprehensive overview of key thermal management strategies, covering heating, passive cooling and active cooling. Attendees will gain insight into the specific cooling requirements of different subsystems and examine various architectural approaches to thermal management. The session will also highlight individual subsystem solutions and integrated vehicle-level strategies to optimize overall system performance.

• EOHVs require more complex thermal management due to more components and more constrained temperature windows
• Batteries, motors, and power electronics have different temperature and voltage windows, often requiring multiple circuits
• Complete vehicle thermal management requires strategic use of both passive and active cooling
• Duty cycle and battery aging effects cannot be ignored when sizing a thermal management system
