Blogarticle about battery cooling in electric vehicles

Curious about how electric vehicle batteries are cooled? 🚗💡
The dominant method currently involves water-glycol mixtures as coolants. The battery is cooled by one or more cooling plates through which the coolant flows. Heat is then transferred to another refrigerant via a heat exchanger for optimal battery operation. Safety, efficiency and longevity are key considerations.

But there is more to it than that...

Our colleague Andreas Varchmin from TLK-Thermo GmbH provides a detailed overview of the basics as well as current and future battery cooling concepts in a blog post called "Battery cooling in electric vehicles".

TLK Energy is premium partner: Climate Neutral Aachen 2030

As part of the Aachen Climate City Contract (CCC) "Climate Neutral Aachen 2030", we at TLK Energy are proud to actively pursue the goal of climate neutrality as a premium partner. We have been CO2 neutral since 2018 and regularly implement measures to reduce CO2 emissions. We also contribute indirectly to the reduction of CO2 emissions through our services, such as simulations and advice on the integration of renewable energy and solutions to increase energy efficiency. Contact us if you would like to assess your company's CO2 footprint and implement steps to reduce emissions. For more information, see our blog article "Reduce CO2 emissions in your company".

"The web simulator is great work! That's how I wanted it to be. After a few teething problems, it all worked out very well."

Stephan Christoph

Crespel & Deiters GmbH & Co. KG

"In our research projects, we perform dynamic simulations and optimizations. We work with different operating systems (e.g. Windows, Linux) and often have very specific requirements for the software interfaces. Here, the communication with TLK Energy was always very good: software interfaces were adapted for us in a short time and questions were answered competently."

Mirko Engelpracht

RWTH Aachen University

"From formulating the task in the proposal phase to the completion of the project, we felt very well looked after. Technical depth was achieved very early on in the close-knit status meetings, which brought interesting discussions and knowledge gains for us. It's wonderful that projects like these exist."

Dr.-Ing. Rüdiger Noack

WAGNER Group GmbH

"The collaboration with TLK Energy was very straightforward and always solution-oriented. Together we have created a web-based ventilation simulator that helps us to communicate the benefits of our Airflow products better.“

Interactive ph-diagram

For refrigeration systems, the log-p-h diagram is probably the most widely used graphical visualization. We use it every day in simulation projects to grasp the state of a system at one sight. For our web-based simulation apps we have developed an interactive log-p-h diagram with JavaScript. You can use it for free and create a cycle yourself.

Interactive hx-diagram

Moisture is important for ventilation and air conditioning applications. Thermodynamicstates and processes with moist air can be graphically represented using the Mollier h-x-diagram. Our powerful interactive version of the hx-diagram helps beginners to understand the basics of hx-diagrams and professionals to speed up common calculations.

McCabe-Thiele diagram

The McCabe-Thiele method uses a phase diagram to determine the number of theoretical bottoms in a column required to achieve the desired degree of separation. The method is a very useful tool for understanding the distillation of a binary mixture.
