Thermal management in hybrid and electric vehicles

Thermomanagement für eine optimale Batterietemperierung


Current lithium ion batteries in new energy vehicles reach their maximum performance, range and service life at a temperature of about 25°C. In order to consistently ensure this temperature level, the operating temperature has to be recorded and the battery has to be cooled or heated if necessary. For an optimal battery temperature control pressure losses in the coolant flow have to be minimized – in each thermal management line system. Consequently the design of these line systems must be adaptable to different vehicle architectures.

Cool systems with high customer benefit

  • Individual service with design and simulation of liquid cooling systems
  • Development and production of preassembled lines and components
  • Individual line solutions with precise routings in diverse cross sections and materials for complex and smallest assembly spaces
  • Integration of sensors, valves and connection systems
  • Quick connect systems from the specialist: space-optimized, error-proof ("Double Lock feature") and installation-friendly

8. Social Media Plugin 

We use social plug-ins of the social network Youtube on our website on the basis of art. 6 par. 1 p. 1 lit. f GDPR in order to make our company better known about this. The underlying advertising purpose is to be regarded as a legitimate interest within the meaning of the GDPR. Responsibility for data protection-compliant operation must be guaranteed by the respective provider. The integration of these plug-ins by us takes place in the way of the so-called two-click method, in order to protect visitors of our web page in the best possible way.

a) YouTube

Our website also uses so-called Social Plugins ("Plugins") from YouTube, the YouTube LLC, 901 Cherry Avenue, San Bruno, CA 94066, USA. "("YouTube"). The plug-ins are marked with a YouTube logo, for example in the form of a "YouTube camera".

When you access a page of our website that contains such a plugin, your browser establishes a direct connection to YouTube's servers. The content of the plugin is transferred directly from YouTube to your browser and integrated into the page. This integration gives YouTube the information that your browser has called up the corresponding page of our website, even if you do not have a YouTube profile or are not currently logged on to YouTube.

This information (including your IP address) is transmitted directly from your browser to a YouTube server in the USA and stored there. If you are logged in to YouTube, YouTube can immediately associate your visit to our website with your YouTube account. If you interact with the plug-ins, for example by pressing the "YouTube" button, this information is also transmitted directly to a YouTube server and stored there. The information will also be published on your YouTube account and displayed to your contacts.

If you do not want YouTube to associate the data collected via our website directly with your YouTube account, you must log out of YouTube before visiting our website. For more information, please see YouTube's privacy policy (

9. Tracking-Tools

The tracking measures listed below and used by us are carried out on the basis of Art. 6 para. 1 sentence 1 f GDPR.

These interests are to be regarded as legitimate within the meaning of the aforementioned provision. The respective data processing purposes and data categories can be taken from the corresponding tracking tools.

a) Google Analytics

This website uses Google Analytics, a web analysis service of Google Inc. "("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there. However, if IP anonymisation is activated on this website, Google will reduce your IP address within Member States of the European Union or in other countries party to the Agreement on the European Economic Area beforehand. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide the website operator with other services relating to website and Internet use.

The IP address transmitted by your browser in the context of Google Analytics is not merged with other Google data. You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the website (including your IP address) and from processing this data by Google by downloading and installing the browser plug-in available under the following link:

Please note that this website uses Google Analytics with the extension "_anonymizeIp()" and therefore IP addresses are only processed further in order to exclude a direct personal relationship.

For more information, please see Google's privacy policy (

b) Google reCaptcha

To ensure that actions are performed by a natural person and not a programmed bot, we use the reCaptcha service of Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; hereinafter "Google").

In this context, abuses and manipulations (e.g. automatic and automated processing) on the Internet are checked on the basis of text distortions or other input fields that cannot be easily read or answered by a machine. For this purpose, data is transferred to a Google server in the USA and stored there; it is not stored on our own server.  By activating IP anonymisation (done by manual adaptation) on our website, your IP address will be shortened by Google within member states of the European Union or in other signatory states to the European Economic Area Agreement. Only in certain exceptional cases is the complete IP address transmitted to the server in the USA. On our behalf, Google will use the information obtained to evaluate the use of these services and, if the data storage is deactivated, to store it for a maximum period of 14 months in accordance with the GDPR. The transmitted IP address of your browser is not merged with other Google data within the scope of reCaptcha.

The service includes sending the IP address and any other data required by Google for the reCap-tcha service to Google. For more information about Google Inc.'s privacy policy, please visit
