（来源：北京消协） 极易发生危险 高速收费卡也能 "爆炸 " ？ 近日有网友表示 高速收费站发放的CPC 卡 （高速公路复合通行卡） 在车内炸了 图源：中国应急管理 该网友的卡片 一面被烧出孔洞露出芯片 另一面的塑料外壳 出现了大小不一的鼓包 针对这种情况 高速客服工作人员解释称 若将CPC卡、ETC 卡 放在车载无线充电板上 或无线充电区域旁 轻则发烫、鼓包 重则起火、炸裂 受损的CPC卡。 图源：中国应急管理 收费卡为何会"炸"？ 为何CPC卡靠近无线充电区域 容易爆炸、起火？ 首先要知道，车载无线充电依靠电磁感应实现能量传输。 CPC卡不是普通的塑料卡，其内部含有微型芯片、天线等金属部件。当它靠近或处于车载无线充电器的充电区域时，卡内的金属部件和芯片会在交变电磁 场中产生"涡流效应"。这一效应与电磁炉加热原理相似，会瞬间产生大量热量。 而卡片塑料封装的外壳散热能力有限，无法及时将热量散发出去。一旦热量快速积聚，卡片温度飙升，就会出现发热、鼓包、变形，严重时会炸裂、冒烟 起火，危及车内驾乘人员安全。 注意：别和手机叠放充电 当高速公路复合通行卡（CPC卡）与手机叠放在充电板上充电时，会产生强电磁场，强电磁 ...

小小的一张高速CPC卡，一旦放错位置竟可能会有危险？ 据中青网消息，近日有网友发视频称，高速收费站发放的CPC卡（高速公路复合通行卡）在车内发生"爆炸"。 受损的CPC卡。图源：网络 高速客服工作人员回复称，如果把CPC卡、ETC卡放在车载无线充电板等位置，卡片轻则出现发烫、鼓包，重则起火、炸裂。 那为什么CPC卡一靠近无线充电区域就会起火、炸裂？背后的原理其实并不复杂。 01 解密发热原因 车载无线充电依靠电磁感应实现能量传输。当高速公路复合通行卡（CPC卡）与手机叠放在充电板上，手机触发充电功能后，会产生强电磁场，这个强电 磁场会同步作用于下方的CPC卡。 本文转自【中国消防】； CPC卡内部含有微型芯片、天线等金属部件。当它靠近或处于车载无线充电器的充电区域时，卡内的金属部件和芯片会在交变电磁场中产生"涡流效应"。 这一效应与电磁炉加热原理相似，会瞬间产生大量热量。 而卡片塑料封装的外壳散热能力有限，无法及时将热量散发出去，热量就会急剧积聚，导致卡片温度快速飙升。 最终，卡片会出现发热、鼓包、变形的情况，严重时甚至会泄漏、冒烟起火，危及车内司乘人员的生命安全。 牢记规范使用要点 1.不要把CPC卡和手机 ...

Core Viewpoint - The article highlights the potential fire hazards posed by glass products, such as empty bottles and mirrors, when exposed to sunlight during the summer months, emphasizing the need for caution in their storage and handling [3][9][17]. Group 1: Incidents of Fire Caused by Glass Products - On June 4, a storage compartment in Beijing caught fire due to sunlight refracting through empty glass bottles, igniting surrounding flammable materials [3]. - A similar incident occurred in Fujian, where sunlight focused through a double-sided mirror ignited a promotional flyer, leading to a fire that destroyed items in the store [5][6]. - In May of the previous year, a backyard fire in Zhejiang was traced back to 80 crystal balls that reflected sunlight, igniting nearby cardboard boxes [8]. Group 2: Other Fire Hazards in High Temperatures - A fire in a vehicle in Beijing was caused by sunlight heating water bottles placed on top of the truck, which ignited surrounding materials [11]. - The structure of common items like bottled water and reading glasses can act as convex lenses, concentrating sunlight and increasing temperatures, which can lead to fires [13]. - Firefighters conducted experiments showing that items like lighters and spray cans can explode when left in a car under direct sunlight, with significant temperature increases observed [15]. Group 3: Safety Recommendations - It is advised to keep items such as magnifying glasses, bottled water, and other glass products away from direct sunlight and flammable materials [17]. - Specific caution is recommended for items like lighters, power banks, and aerosol sprays, which should not be left in vehicles during hot weather [17].
