Get a quoteThough, the overall risk for a faulty cell in the overall system remains the same, the safety in general is enhanced by dividing the battery in more than one pack, as the risk that there is a faulty cell in each pack is a lot lower than if all are connected in series. Moreover, these failures would have to appear at the same time.
The amount for cooling on the other hand might even be reduced as it might be possible to cool only the HP pack in a hybrid battery system as the load on the HE pack is relatively moderate. The effort for the battery monitoring as well as the contacting and wiring will remain approximately the same.
Batteries are fundamental to modern energy systems, serving as the backbone for everything from mobile devices to electric vehicles and renewable energy storage. As these applications expand, the limitations of current battery technologies become more apparent, driving a critical need for advancements.
Moreover, a high calendric lifetime is very important as for example the mean vehicle lifespan in Germany is currently 12 years. At the same time, the battery is the most expensive component in the vehicle , , triggering customers’ fears of an early failure.
1. Introduction In the recent years the focus in battery research shifted from consumer electronics and power tools to large scale battery systems as a result of emerging renewable energies and key vehicle manufacturers gradually electrifying their fleets to reduce local emissions , .
