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.
Battery protection circuit is applied to protect the battery from overcharging, over-discharging, short circuits and other dangerous conditions to ensure the longest battery life for its use and to ensure battery safety.
Here is how the battery protection board works for overcurrent protection: 1. Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit.
Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit. This is usually done by detecting a BMS over voltage drop in the circuit or by using a current sensor. 2.
Overcharging, overdischarging and overheating can be protected by the battery management system, where the key is the protection threshold setting of voltage and temperature. Short circuit includes internal short circuits (ISC) and external short circuits (ESC).
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.
