Recently, some netizens posted a video showing that a CPC card issued by a high-speed toll station suddenly burst inside the car. The picture shows,Holes were burned out on one side of the card, the chip was exposed, and there were many bulges in the plastic casing on the other side. This situation caused car owners to pay attention to driving safety.
In fact, high-speed toll cards are in danger when they encounter wireless charging boards. The principle behind it is not complicated.Car wireless charging relies on electromagnetic induction to transmit energy. The strong electromagnetic field generated will act on the chip, antenna and other metal parts in the card, forming an eddy current effect similar to the heating of an induction cooker, instantly generating a large amount of heat.
The plastic casing of the CPC card has poor heat dissipation ability. The temperature continues to accumulate and the temperature rises suddenly, eventually causing explosions and fires, endangering the safety of people in the car.
When using the CPC card in daily life, you need to keep in mind the regulations. Do not put it on the wireless charging pad with your mobile phone, and keep it away from the strong magnetic field environment in the charging area. After receiving it, it can be placed in the vehicle's special card slot, glove box, etc.
In addition to CPC cards, placing bottled water, glasses, lighters, perfume and other items in the car also poses safety risks. Exposure to high temperatures or being close to heat sources can easily cause fires and explosions. Car owners need to clean up dangerous items in the car in a timely manner to avoid driving risks.
