The reasons for the slow wireless charging of BYD Qin plusev are many. First of all, BYD Qin plusev uses wireless charging technology for electric vehicles, compared with wired charging, wireless charging efficiency will be relatively low, because there will be energy loss in the transmission process. Second, wireless charging requires a high alignment between the vehicle and the charging dock, and if it is not well aligned, the charging efficiency will also be affected. In addition, the power of BYD QinPlusev wireless charging system is relatively low, so the charging speed will be correspondingly slow. In summary, the reasons for the slow wireless charging of BYD Qin plusev mainly include low wireless charging efficiency, high alignment requirements, and low power factors.
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.
In addition, the current bottleneck hindering the large-scale use of wireless inductive charging technology is mainly about radiation concerns, because wireless charging will generate a strong magnetic field. When a person or animal is placed between the electric vehicle and the charging device, electromagnetic harm is possible. Therefore, ensuring the safety of wireless charging systems is also a key node
