1, advantages: non-contact, no wire, mobile. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
2, advantages: the use of wireless magnetic induction charging equipment can be invisible, the equipment wear rate is low, the application range is wide, the public charging area is relatively reduced; High technical content, easy to operate, canImplement relatively long distance radio energy conversion. Disadvantages: Although the equipment has high technical content, the economic cost of the equipment is higher and the maintenance cost is large; Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high.
3, the shortcomings of mobile phone wireless charging although the technical content of the equipment is high, the economic cost of the equipment is high, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
4, the harm is relatively small can be ignored, noThe above wireless fast charge is not as fast as the wired fast charge for 1 hour and 30 minutes, which is not a fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
2, the efficiency of wireless charging is lower than that of wired charging, but in the future, with the rapid progress of wireless charging technology, it is likely to be better than wired charging in charging efficiency. However, at present, the technology of wireless charging is not advanced enough, so the charging efficiency of wireless charging technology is lower than that of wired charging. At this stage, wireless charging is more as a supplement and auxiliary to wired charging.
4, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable,Charging speed is also faster than wireless charging.
5, the convenience of wireless fast charging does not bring a significant increase in charging speed, but may be slightly lower than wired fast charging. The power output of the wireless fast charger to the wireless base is not the final output power of wireless charging, but the input power of the wireless charger. The charging speed of wireless chargers installed on new energy vehicles is limited, which may be due to compatibility issues between external chargers and on-board charging systems. 6. New data show that while wireless charging may seem convenient, there is a significant gap in its efficiency. According to OneZero and iFiIn xit's in-depth study, wireless charging technology consumes about 47% more energy on average than wired charging when charging a smartphone, which undoubtedly increases energy consumption. The appeal of wireless charging is that it eliminates the hassle of plugging and unplugging cables, but this is not the case.
1, wireless charging than wired charging more damage to the battery. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging is more damaging to the battery, because wireless chargingMore heat will be generated, and the heat generated will cause greater 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.
2, wireless charging than wired charging more damage to the battery. In fact, we all know that as long as it is charged, it 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, and the heat generated will cause more damage to the battery.
3, on the batteryThe wear and tear is the same. First of all, wireless charging and wired charging have the same loss of battery. Because whether it is wired charging or wireless charging, it is necessary to regulate the voltage of the electricity sent through the last step, but the path of the two is different. Wireless charging damage battery: Wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact.
