Battery protection circuits are crucial components that safeguard lithium-ion batteries from potential hazards like overcharging, over-discharging, and short circuits. These circuits monitor the voltage and temperature of the battery, ensuring that it operates within safe limits.
For this reason, the cells and charge/discharge circuits of lithium-ion batteries currently on the market are always equipped with a control function called “primary protection” to prevent problems that could lead to accidents, such as overcurrent or overcharge. However, even the very best electronic circuits can fail in rare cases.

The most common type of BMS short circuit protection is thermal cutoff, which will activate when the battery temperature reaches a certain point. Other types of protection include fuse cutoff and electronic cutoff. Most lithium batteries have a short circuit protection setting of around 200-300mA. This is usually plenty to protect the battery ...
Battery protection circuits for the most demanding applications are operated mostly by Integrated Circuits (ICs) typically using MOSFETs to switch lithium cells in and out of circuit. The over-current protection is normally provided when the IC detects the upper current limit of the battery being reached and then interrupts the circuit.
