1, that is, in the process of charging and using electricity, there is always some power consumption and residue. So the charge is slow. Current rechargeable batteries, whether mobile phones or cars or other, are facing the problem of "capacity attenuation". In the process of charging and using electricity, there is always some power consumption and residue.
2, but it is said that the charging speed of Han EV wireless charging board is slow, estimated to be about 10w-15w, but the heat of wireless charging is really large, the next time I have time to take thermal imaging to test the temperature of charging, on wireless chargingThe electricity also needs to be equipped with an official wireless fast charge.
3, BYD Han wireless charging switch is located in the front of the center console central armrest storage box. The mobile phone wireless charging area of BYD Han EV model is located in the front of the central armrest storage box of the center console. When the vehicle power gear is in the "OK" gear, the phone can be placed on the non-slip rubber mat in the wireless charging area, with the phone screen facing up. In this position, the phone will automatically start wireless charging, and the charging icon will be displayed on the multimedia UI interface.
4, but Han EV also has some shortcomings, wireless charging is more chicken ribs, mobile phones put on, showIt shows charging, which may be because the power is relatively small, or it may be because I have a short charging time each time, and I don't feel the battery of the phone has changed. Han's car storage space is relatively small, armrest box capacity is too small, put a few packets of small paper towels are full, drinks can not be put.
5, BYD Han internal configuration In terms of internal configuration, BYD Han not only uses leather seats and driver assistance system, but also uses blade batteries and intelligent temperature control management system. At the same time, in terms of comfort configuration, BYD Han also uses a hidden anti-clip door handle, co-pilot gentleman button, mobile phone wireless charging and 16-inch central control display Car wireless charge slow Car wireless charge slow , this was originally the weakness of BMW 5 series wireless charging shortcomings.
2, the BMW 5 series has a wireless charging board in front of the shift lever, and only need to put the mobile phone supporting wireless charging on the wireless charging board after the car is powered on. The same oil film requirements, synthetic oil can be achieved with a lower viscosity, and mineral oil requires a thicker viscosity relative to synthetic oil to achieve such requirements.
3If the phone is abnormally hot when charging, you can check whether the charger used is original, such as using other brands of high-current charger, the heat will increase when charging, it is recommended that you replace the original charger, and check whether there is software running in the background of the phone, if there is an attempt to close.
Advantages: Convenience. Just put the phone in the designated position of the car, you can wireless charging, no need to use the data cable to connect the phone and the car, it is very convenient to use. Good compatibility. Charging with data cable is requiredSelect the appropriate cable according to the phone charging port, such as type-c and Apple data cable, and wireless charging does not need to distinguish, can be unlimited compatible. Cons: Slow charging speed.
The advantage of automobile wireless charging technology is that there is no exposed connector for wireless charging of electric vehicles, which can adapt to a variety of harsh environments and weather, and avoid safety hazards such as leakage and electricity running. The disadvantage is that the power is small, it can only be slowly charged, and the transmission efficiency is lower than that of wired charging. Inductive charging is more stringent for vehicle location. In addition, compared with the charging pile, the cost is higher, and the charging standards of various brands are different.
This wireless chargingThe technology is superior to electromagnetic induction wireless charging technology, which not only extends the transmission distance, but also does not require the position between the coils to be completely consistent. In addition to the above two wireless charging technologies, there are also electric field coupling wireless charging technology and microwave resonance wireless charging technology. Although wireless charging technology has some years of development, many problems restrict its universal application. Wireless charging opens up a new charging mode for smart phones, getting rid of the shackles of traditional charging data cables.
Advantages and disadvantages of wired charging and wireless charging The advantages of wired charging are fast charging speed, good stability, and data transmission can also be carried out at the same time. The disadvantage isNeed to connect cable, use is not convenient enough. The advantage of wireless charging is that it is easy to use, does not require a cable, and only needs to put the device on the charging base to charge. The disadvantage is that the charging speed is slow, the charging efficiency is also low, and the device needs to be placed on the charging base, which is not flexible enough.
Nowadays, many mobile phones that support wireless charging are electromagnetic induction, and the advantage of this inductive charging is that the energy conversion rate is high. However, for wireless charging systems, the charging efficiency has a direct relationship with the distance between the transmitting coil and the receiving coil, the position deviation, and so on, once the two coil positions are slightly deviatedIt will seriously affect the efficiency of wireless charging, and can only achieve one-to-one charging.
