（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 ...
