Similar to how the batteries in new energy vehicles can experience thermal runaway and catch fire, the batteries in e-cigarettes also pose a risk of thermal runaway, potentially leading to explosive incidents.<\/span><\/p>\n

To enhance the safety of e-cigarettes, in addition to ensuring battery quality and the reliability of control chips, certain countries have mandated the use of fuses and other measures for added protection. For instance, the U.S. PMTA requires products to comply with UL 8139 standard certification. Furthermore, reports indicate that some countries in the Middle East have begun to implement similar requirements.<\/span><\/p>\n

\"PPTC<\/p>\n

The UL 8139 standard addresses battery protection by outlining how to implement an alternative method to safeguard the battery circuit in the event of an MCU failure, thereby providing dual circuit protection. It is understood that safety concerns arising from MCU malfunctions and thermal runaway due to lithium battery short circuits can be mitigated through the use of PTC (Positive Temperature Coefficient) protective components, ensuring enhanced safety.<\/span><\/p>\n
