Thermal propagation triggering and mitigation in medium- and large-format battery modules
by Iris Su, Project Engineer II, Inventus Power A recent change in Li-ion battery pack safety is the shift from a focus on just prevention to one that emphasizes prevention and mitigation. Battery pack designers who were once focused on preventing thermal runaway (TR) are now taking increasing measures on preventing single cell failures within […]
Applying large banks of supercapacitors
It pays to know techniques for mitigating leakage current and over- voltages in uses where several supercapacitors work in parallel. Michele Kinman Advanced Linear Devices Inc. In applications requiring rapid charge/discharge cycles or short-term energy storage, you’ll often find supercapacitors connected in series or parallel. However, there’s a potential problem when supercaps are wired together […]
