Electric mobility, electric bicycles, stationary energy storage systems, battery operated power tools – whole sectors are stirred up by ever more powerful lithium-ion batteries.
Energy storage especially requires batteries having a high energy density, a low internal resistance and a low self-discharge rate. In the light of the present state of the art, primarily lithium-ion batteries meet these requirements. In particular powerful lithium-ion batteries, however, have a safety gap – due to very small internal resistance values of some of these batteries very high short-circuit currents may occur. ESKA offers specially designed fuses for such DC applications, starting with sub-miniature fuses up to NH fuses depending on the applied energy density.
