This paper deals with the safety devices incorporated in the most commercial 18650 lithium-ion (Li-ion) cells. The systems have been effective at cell level, but with the development of Li-ion cells in module or battery pack configurations, safety device breakdown occurs during battery operation. The 18650 cells include a current interrupt device (CID), which manages cell overcharge by opening the...
In this paper, numerical methods to detect series arc fault in lithium-ion batteries are presented. The arc signals which are required for detecting arc fault are obtained using a test bench on which the Current Interrupt Device (CID) opens dynamically by contact release, associated with a 48 V DC battery pack and a resistor which can deliver a maximum of 1000 A. A comparison between the signals with...
This paper focus on the prevention and risk management of DC arcs in batteries. Indeed some commercial Li-ion batteries include Positive Temperature Coefficient (PTC) and Current Interrupt Device (CID) to manage safety concerns. PTC is used to prevent too high currents inside the cell. CID is used to manage cell over-charge by opening the cell circuitry by internal pressure increase. Analysis will...
