The battery explosion threshold temperature depends on the specific chemical compounds in the lithium ion battery. Different NTC thermistor designs are being used depending on the temperature limits. For the widely used lithium cobalt oxide batteries in consumer electronics the upper safe temperature limit is 130 °C to 150 °C.
Temperature protection is possible by connecting an NTC thermistor to the dedicated connection pin. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Fig. 1 is a block diagram of circuitry in a typical Li-ion battery pack. It shows an example of a safety protection circuit for the Li-ion cells and a gas gauge (capacity measuring device). The safety circuitry includes a Li-ion protector that controls back-to-back FET switches. These switches can be
Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
Selection of NTC thermistor temperature sensors for the Li-Ion battery may require additional considerations: Ametherm NTC Thermistor Temperature Sensors have both electrical and mechanical specifications ideal for use in Li-Ion battery charging applications.
Integrating NTC thermistors into battery packs is crucial to ensure their safety and performance. By continuously monitoring temperature, NTC thermistors allow for proactive measures to be taken in case of abnormal conditions.
