Battery Technology. How Does a car Battery Work and What Are the Key Concepts?

2024 was again a record year for the sales of EV (electrical vehicle) in Denmark and EV sales has now overtaken sales of ICE (Internal Combustion Engine) cars. 

The technology is still developing rapidly, but the core concepts are more or less the same and on this event, you will learn about them. 

As a consequence of the still increasing sales, we also face an issue about recycling of batteries. This area is still early stage, but needs to be developed due to both environmental, geopolitical and economic reasons. 

We are not going to solve all matters regarding the recycling of batteries at this event, but you will hear about a case regarding 2'nd life usages of EV batteries.  

Agenda:

17:30 - 18:30

•  Maciej Świerczyński, Senior Researcher at XOLTA, will talk about batteries in general:

18:30 - 19:00

• Sandwich and Networking 

19:00 - 20:00

• Thomas Meier Sørensen, CTO at 4-Leaf-consulting, will talk about several other relevant topics in relation to battery systems and second life usage;
