MAIN DAY ONE | NOVEMBER 16, 2022

• Overview and comparison of cooling concepts within integrated BEV powertrain systems
• Thermal interactions between powertrain components (e-machine, power electronics and gearbox)
• Correlation between cooling performance and powertrain abilities

 9:20AM Question & Answer Session

With internal combustion engine applications, both heat and energy come from the wasted heat from the engine. On the other hand, every ounce of energy that is used to either cool or heat the EV cabin requires more cell energy, which adds not only cost but also weight to the vehicle.

 Optimization of the thermal system becomes a much more critical factor for battery electric vehicles than it used to be for the internal combustion engine vehicle.

• Measure to reduce weight in the cooling system while improving efficiency
•  Application of new technologies for system optimization
•  Learn how to optimize or combine the power electronics loop and the battery cooling loop into one
• Sharing experiences and lessons learned to advance thermal management technology for EV/HEV
• Operational strategies of Heat Pump Systems in EV/HEV

 10:00AM Question & Answer Session

This technical presentation tackles the biggest thermal management challenges the industry is facing, with an expert from SimScale discussing applications and benefits of using cloud-based engineering simulation to develop and optimize innovative electronics cooling/thermal management solutions for EVs and HEVs. In the presentation, Mike Dombrowski will cover: 

• New developments in the cooling/thermal management simulations of EV batteries, and other EV powertrain components
• Simulation solutions for both passive (convection, radiation) and active (cold plate, heat exchanger, fans) cooling approaches
• Latest innovations for simulating cabin comfort with CFD

 10:40AM Question & Answer Session

• Mitigating overheating battery cells and thermal runaway
• Insulation solutions to protect and regulate heat
• Materials to restrict heat propagation

11:50AM Question & Answer Session

One of the key concerns with DC fast and ultra-fast charging is the voltage level – it can vary from 400 to 1000V. To control the heat generated by such high-power transfer, EV manufacturers must employ highly effective thermal management strategies to maintain consistent and reliable power delivery, both for the charger and the battery pack.

• This presentation sees a leading thermal management expert on best practices and actual technological solutions to control thermal conditions for DC fast charging reliability.
