Thermal design challenges

Increasing the range and improving battery charging speeds are two of the greatest challenges EV engineering teams face today. Electric vehicles and their batteries often perform the best within a very specific temperature range. This means finding cooling solutions that account for thermal efficiency, temperature uniformity, size, weight, and cost. Needless to say this isn’t a mean feat.

Enabling longer range and faster charging

Our AI-based generative thermal design solution, Coldstream, definitely can make this task a lot easier for engineering teams, as already proven in Formula E racing. Our software enables you to create the perfect heatsinks, in days instead of months. You set all the boundaries you need for your project and ColdStream will go through millions of possible solutions to find the perfect one for you. All with the power of super computing and with the security of military-grade encryption.

Battery thermal management

The most challenging component to achieve better performance and improved charging speeds in EV’s is probably the battery. One way Coldstream can assist in resolving this challenge is with the design of battery cold plates. For more information about designing battery cold plates for EV’s with Coldstream, watch our on-demand webinar.

Faster charging speeds for EV batteries

With 350 kW charging in our near future, EV engineers are presented with a number of new challenges. Charging batteries at these aggressive rates comes with a great amount of heat generation in the process. Creating concerns about the battery lifetime and the temperature stability.

Thermal management for electric motors

Keeping the electric motor at the right temperature is another important piece of the puzzle. When an electric motor gets too hot, the energy consumption will significantly increase. One of the most important parts in keeping the electric motor at the right temperature is the cooling jacket.

One of our projects is in Formula E, where we used Coldstream to design the electric motor cooling jacket. In this case we were able to decrease the electric motor temperatures by 21% and we improved the battery power drain by 80%. Read all about it in our article about how artificial intelligence is driving better cooling for critical EV components.

Why choose generative thermal design

For Electric Vehicles
The EV sector is changing rapidly due to customer’s changing demands. People want cars with a longer range and with faster charging capabilities.

As competition is increasing in the EV market, we need to create better thermal designs. And we need to deliver them even faster than ever before.
  • High temperature uniformity
    The small channels have a high contact area with the liquid, improving the convective cooling.
  • High thermal mixing
    The small pockets ensure that the thermal boundary layer is interrupted and subsequently re-initiated.
  • High heat transfer
    The small structures and pins have a high contact area with the liquid, resulting in very high heat transfer.
  • Effective flow
    The large channel carries cold liquid through to the smaller channels, which then regulate flow through a bottleneck effect to ensure even distribution.

With generative design, the role of designers and engineers is to frame the problem and define the goals. The software then interprets and uses this to guide its way towards an optimal design option.
