ElringKlinger’s zero-emission technologies include battery and hydrogen fuel cell technology as well as electric drive units. Battery-powered vehicles are more technologically developed, ready for the mass market, and cheaper to buy. Their hydrogen-powered counterparts, by contrast, are quicker to fill up, achieve longer ranges, and tend to contain much smaller and more lightweight battery packs. In both areas, ElringKlinger has the development and manufacturing expertise necessary to offer modules and components suitable for series production. After all, both technologies have a role to play in making mobility as a whole climate-neutral. On the one hand, battery technology has clearly come out on top for short to medium-length trips in the passenger car segment as refueling time is less of an issue here. On the other hand, the hydrogen fuel cell is proving increasingly popular for long journeys and heavy-duty transport since the vehicles can travel further in relative terms without having to stop for fuel.
ElringKlinger is actively driving carbon-neutral mobility forward – on the roads, off the roads, on the rails, and in the water. The Group considers all the relevant up- and downstream environmental issues at an early stage, while development is still ongoing. This is particularly important in order to prevent the risk of natural and non-renewable resources being exploited.
The ElringKlinger Group’s battery technology operations are growing fast on both the development and production sides. Developers are aiming to increase the acceptance of battery-powered vehicles through technological progress, so the focus in all developments has always been on solutions for the most important purchasing criteria: range and charging speed. And this is why the latest battery concept for a manufacturer of sports cars consists of a pack with over 400 pouch cells that enable a capacity of over 70 kWh. Armed with 800 V technology and a particularly efficient cooling system, a battery capacity of 80% can be reached in as little as five or so minutes when the sports car is being charged. Alongside fast-charging technology inside the electric car, there is also a need for ultra-fast charging stations, and it was precisely with this in mind that ElringKlinger has developed another 800 V battery storage system with its own prismatic modules and readied it for series production. Arranging these batteries in parallel produces a level of capacity and power for autonomous fast-charging stations that the conventional power grid cannot yet guarantee.
Besides the passenger car segment, ElringKlinger is also focusing on off-highway markets for its batteries. The Group believes that there is potential in agricultural and construction machinery, electric boats, and small commercial vehicles. Just like carmakers, the key players in these segments are also facing the challenges of manufacturing climate-friendly products. The modular approach followed by ElringKlinger’s battery modules offers a crucial advantage in this regard as it enables a wide range of applications in different-sized storage systems within a short space of time.
