So far, the development of battery cells has focused on the highest possible energy density, while the speed of charging and discharging is less of a priority. Especially for electric vehicles, this characteristic is particularly important, as in addition to the storage capacity, the fast power consumption of the battery is also crucial for the highest possible recuperation rates. This leads to higher ranges or to smaller and lighter battery packs.

DESTEN has managed to combine high and constant power delivery, extreme recuperation, and high energy density in one cell type. Given that the cells heat up very little while charging, the battery can be air-cooled, which means a weight saving of several hundred kilograms. This allows, among other things, for the development of dynamic, full-throttle, electric vehicles; the Piëch Mark Zero depicts this impressively. The technology is also extremely safe, the battery, has been tested by leading independent institutions and companies like Hofer Powertrain and certified by TÜV. The unique combination of these factors can now create the necessary circumstances for many consumers to switch to electric vehicles.

Research and development at DESTEN is not only limited to the core product ‘battery’. In order to realise fast charging effectively, the innovation of other components is imperative: charging cables and plugs must be able to transmit very high currents during fast charging, which can lead to significant heat generation in conventional cabling, requiring liquid cooling and other supporting technologies. DESTEN has, therefore, developed supporting components, with small dimensions and low weight, which can transmit significant power with substantially less heat generation, thus circumventing expensive and heavy cooling infrastructures.
