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)
A Lithium-ion battery protection circuit is specifically designed to protect lithium-ion cells. It typically includes a combination of electronic components such as transistors, diodes, and resistors that work together to control the current flow.
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.
Lithium batteries have the advantage of high energy density. However, they require careful handling. This article discusses important safety and protection considerations when using a lithium battery, introduces some common battery protection ICs, and briefly outlines selection of important components in battery protection circuits. Overcharge
Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe) More information on why batteries fail, what the user can do when a battery overheats and simple guidelines using Lithium-ion Batteries are described in BU-304a: Safety Concerns with Li-ion.
For example, by connecting two 5-cell Li-ion battery protection ICs with their COUT and DOUT pins, those ICs can protect a 10-cell Li-ion series battery. Cascade connection enables protection ICs to support multi-stage batteries even though there are no ICs capable of monitoring those batteries with a single chip.
