Electrical Energy Storage protection by fuses, enabler for safety

Abstract:
Safety of the EES application is becoming a major focus recently. Series of incidents have pointed out that safety has not yet been addressed properly due certainly to the fast growth of EES installations. Smart monitoring systems have allowed mitigating catastrophic failure of EES installation however fuses remain the safest solution once everything else has failed. Today’s EES installers face the challenge of operating voltages of up to 1500 V with available fault currents larger than few 100 kA. The safety and growth of EES applications are now started to happen thanks to introduction of fuses specially designed for EES applications along with variety of applications notes on proper fuse selection complimented by test labs simulating actual EES fault currents and development of new IEC standards for battery usage.
