How the GIGAFUSE helps maximize safety in advanced battery systems

In advanced battery systems, the quality of the power electronics helps determine the quality of the final product, its level of functionality, and its reliability. This is emphasized in the latest battery power management and charging systems that use wide-bandgap semiconductors and improved power topologies. In such advanced electronics, if the safety systems do not work quickly and reliably, the entire battery system can suffer a catastrophic failure that could seriously impact the product and its user.

THE DEMAND FOR IMPROVED STORED ENERGY SYSTEMS

Almost every advanced application space currently under development requires next-generation battery systems. Smart grid-level energy systems need more power storage just as much as advanced electric vehicles (EVs) do, and those needs are literally connected (Figure 1). Each space has its own requirements, but the core need of safe, reliable, and economical energy storage is fundamental. In life-critical application spaces such as automotive safety, the importance of fail-safe subsystems is paramount. The battery system in an EV is similar to the gas tank in a fueled vehicle, in that the stored energy needs to be safe. There is a lot of energy in a modern battery, and catastrophic failure can certainly involve thermal runaway (fire). The increasing level of publicity being given to EV fires has brought more attention to this danger, which is why safety concerns must be addressed in order avoid adversely impacting public EV adoption.
The higher cell densities in advanced battery systems demand proper safety protocols and devices as the power levels involved present a significant challenge when it comes to managing short circuits. To create a robust and safe system that helps ensure reliability over a given vehicle’s lifetime, manufacturers must integrate high-performance components into their designs
