Battery manufacturers provide a value of short circuit current which needs to be used for validation of proper protection device. Duration of this short circuit current can be of few seconds before a battery failure occurs. The characteristic current and duration changes depending on the battery type.
Not all cells have built-in protections and the responsibility for safety in its absence falls to the Battery Management System (BMS). Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
The risks of external short-circuit of battery modules with different voltage levels are tested for the first time. Two types of typical risk modes and influencing factors of ESC of battery modules are analyzed and proposed. The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified.
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high. Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe)
