The first kind of wired charging, this charging method with the development of science and technology to extend the flash charge, fast charge, the result is to help users quickly full mobile phone battery.
Wireless charging hurts the battery more than wired charging. Any charge will cause damage to the battery, but wireless chargingCompared with wired charging, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
In fact, we all know that as long as it is charging will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, resulting in heat damage to the batteryIt's relatively big. Whether the line charge charges the battery is controlled by the internal circuit of the mobile phone, and the initial voltage for the normal operation of the internal control circuit of the mobile phone is provided by the battery.
1, the answer is: there will be harm, shorten life. We all know the characteristics of lithium batteries, lithium battery operating temperature is generally 0-40 ° C, if long-term in a high temperature state of 60 ° C, it will damage the battery. In fact, there are so many root causes of mobile phone wireless charging fever, know the reason, you can chooseMore suitable products, rest assured to enjoy the fun of wireless charging: the choice of solutions.
2, wireless charging, mobile phone fever is a normal phenomenon, but overheating may be dangerous. Wireless charging technology uses the principle of magnetic coupling to transfer power between the transmitter and the receiver. In this process, part of the electrical energy will be converted into heat, causing the phone and charger to heat up. This is a common phenomenon of wireless charging and does not mean there is a danger.
3. Car wireless chargers usually use a variety of safety protection measures, such as overcurrent protection, overheat protection and short circuit protection, to ensure thatThe temperature below 40 ° C is normal and will not cause damage to the equipment. However, the heating temperature exceeds the wireless charging operating temperature range 50 ° C, you need to pay attention to, because it will have an impact on the equipment.
2, whether wired charging or wireless charging, the charger or mobile phone will normally charge heat, under normal circumstances, the mobile phone charging temperature below 40 degrees, charging head (or wireless charger) temperature below 60 degrees at noon, can be considered normal, the lower the temperature the better.
3, began to implement, most of the Android handThe machine uses this standard. Pay attention to the temperature of the wireless charger, a high-quality wireless charger is able to control the temperature below 40 ° C. To have a temperature control function, the temperature exceeds the appropriate range of automatic power off. Wireless chargers have a conversion efficiency problem, the current mobile phone wireless charger conversion efficiency is more than 60%-80%. Under the same conditions, the higher the efficiency, the faster the charging speed.
4, Wireless charging operating temperature range We all know the characteristics of lithium batteries, lithium batteries working temperature is generally 0-40 ° C, if long-term at 60 ° CAt high temperatures, the battery will be damaged.
