A propos de votre organisation

Danubia NanoTech is expert for carbon nanomaterials with the EU Seal of Excellence label. For batteries, we developed a flexible graphene temperature sensor to monitor the temperature directly on the surface of the battery cells. The sensor is extremely thin film with high accuracy, ultra light and while produced by spray-coating, it is also very variable for application on flexible (curved) surfaces and practically unlimited in terms of coverage area. On self-adhesive film, the sensor's application is very easy, with lower material costs (compared to widely used platinum sensors), with fast response and excellent accuracy.

 

We successfully tested and validated this sensor on the batteries for the distribution grid/EV charging support. It can be however equally interesting for EV batteries to prevent unbalanced usage of the cells in the battery pack. Managing of an even distribution of temperature is key to operating of EV batteries close to their performance limits. Maximum battery life can be achieved if temperature of individual cells does not differ significantly. The detailed monitoring of the battery temperature directly on the individual battery cells can thus bring great benefits and prevent potential negative effects of overheating which implicitly improves the state of health i.e. lifetime of batteries as well as prevents their technical failures.

 

Danubia's research, development and production is I​SO 9001:2015 certified.​
