How can science help OEMs to meet electric vehicle safety regulations and improve cooling system reliability?

With new legislation and stricter emissions targets driving hardware development, there is inevitably going to be a more varied vehicle parc across the globe in the coming decades. This will include electrified vehicles such as battery electric vehicles and different types of hybrids. With electrified vehicles comes questions around battery cooling system reliability and battery safety. This is leading to some countries looking to implement new regulations to ensure these vehicles are safe and reliable. For example, regulations around system reliability and safety when it comes to batteries and battery cooling systems in electrified vehicles are being implemented in China. With China being the largest automotive market globally, it is likely that we will see other countries such as Europe and North America following suit.

This talk will look in detail at how engineered fluids and polymers can help OEMs to meet these new regulations. Our team of experts will discuss how dielectric fluids can be used in place of water glycol fluids in cold plate cooling systems. Sharing our findings from work with electric car racing teams we will discuss how dielectric fluids perform in cold plate cooling systems and share the reasons as to why this is a safer and more reliable fluid choice in this application for not only battery electric vehicles but also hybrids.

We will also discuss how innovative chemistry can be help suppress fire in battery electric vehicles and hybrids. This will touch on the battery cooling system as a whole from the formulated dielectric fluids that can be used to immerse cool the battery to the thermoplastics that can be used to construct the casings within the system. We will also discuss the factors that OEMs need to consider when designing a system that will be reliable such as material compatibility. Choosing the right components will enable a safer and more reliable system.

Finally, safety and system reliability doesn’t stop at the vehicle itself. How do we ensure that the system is safe and reliable whilst being charged? Enabling extra fast charging is going to be crucial in the adoption of electric vehicles. We will discuss how immersion cooling fluids can be used in this application as well as how charging can be enabled by flame-retardant thermoplastic polyurethane (TPUs) that are optimised to be robust, flexible and thermally stable
