To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
Abstract: As large-scale lithium-ion battery energy storage power facilities are built, the issues of safety operations become more complex. The existing difficulties revolve around effective battery health evaluation, cell-to-cell variation evaluation, circulation, and resonance suppression, and more.
Stranded energy is a hazard because it still contains an unknown amount of electrical energy and can pose a shock risk to those working with the damaged Energy Storage System (ESS). Additionally, stranded energy can lead to reignition of a fire within minutes, hours, or even days after the initial event.
The energy stored and later supplied by ESSs can greatly benefit the energy industry during regular operation and more so during power outages.
A stranded ESS battery, which is commonly found after an ESS fire has been extinguished and the battery terminals have been damaged, poses a shock hazard to those working with the damaged ESS. It still contains an unknown amount of electrical energy, and this stranded energy can also lead to reignition of a fire within minutes, hours, or even days after the initial event.
