With the continuous progress of automotive technology, the wireless charging function of mobile phones has gradually been applied and popularized in cars, from millions of luxury cars to 100,000 yuan entry models, most of which are equipped with this function. Compared with the traditional charging method of traditional connection, the biggest advantage of in-vehicle wireless charging is that it has a high adaptation rate, and mobile phones that support the Qi wireless charging protocol can be charged, so you don't have to carry all kinds of charging cables when you go out when driving, which can effectively avoid the clutter of the lines in the car.
Since the launch of the mobile phone wireless charging performance test in May 2023, the number of tested models has reached 68 so far, covering fuel vehicles and new energy vehicles of independent, joint venture and imported brands. Today, we will rank by the two dimensions of mobile phone charging volume and mobile phone heat generation, to see which models stand out?
In order to simulate the real usage environment, the Apple iPhone 13 Pro and Huawei P50 Pro were used as fixed test machines in the test. During the test, the charging efficiency of the two mobile phones was tested by first draining the battery and then placing them on the car wireless charging pad for 15 minutes. After charging, the backs of both phones were measured using an infrared thermometer to test the heat generated by the body.
1. Ranking of mobile phone charging volume
1. Apple's mobile phone charging volume ranks TOP10
By comparing all the models tested so far, in the charging capacity test for the Apple iPhone 13 Pro, the NIO ET5T performed relatively better, with the phone charging capacity reaching 17% in 15 minutes, and the charging efficiency is good. GAC Trumpchi ES9 followed closely behind, and the mobile phone charging capacity also reached 16% within 15 minutes, and the charging efficiency was also remarkable. The Ideal L7, Chery Arrizo 8 and Polestar 4, which ranked third to fifth, all had a charging capacity of 15%, while the models ranked sixth to ninth had the same charging capacity of 14%. It is worth mentioning that the charging capacity of the Roewe RX9, which ranks 10th, has also reached 13%, which is not much different from the top models.
Overall, the top 10 models on the list all support Apple's fast charging protocol, and the charging capacity within 15 minutes is at or above 13%, and the overall test results are not far behind.
2. Huawei's mobile phone charging volume ranks TOP10
In the charging test for Huawei P50 Pro, judging from the list, the Denza N7 won by a large margin, charging the phone up to 35% in 15 minutes. Ranked 2nd to 4th, the VOYAH Chasing Light, Polestar 4 and AVATR 12 all have a charging capacity of more than 30%, and the charging efficiency is also worthy of recognition. It is worth noting that the charging capacity of the three models of the Ideal L7, Wei Gaoshan and HiPhi Y, which ranked 8th to 10th, is 22%, which is far behind the Denza N7.
Overall, the top 10 models on the list all support Huawei's fast charging protocol, but the charging efficiency gap is more obvious. For example, although both models support 50W fast charging, the actual charging capacity is quite different, reflecting the differences in the wireless charging performance of different brands of Huawei mobile phones.
Second, the ranking of mobile phone calorific value
1. Apple's mobile phone heat ranking TOP10
Judging from the ranking of mobile phone heat, when charging the Apple iPhone 13 Pro, the second-generation Haval big dog performs eye-catchingly, and the temperature of the mobile phone remains unchanged before and after charging, which is mainly due to the global heat dissipation design of the car's wireless charging pad, and the entire charging pad is equipped with heat dissipation holes, which has excellent temperature control. In addition, the models ranked 2nd to 10th also perform relatively well in controlling the charging temperature of mobile phones, and the temperature difference before and after charging is controlled within 3 degrees Celsius, and it is difficult to detect temperature changes in the hand.
Overall, the top 10 models on the list have reasonable temperature control for Apple mobile phone charging, and the temperature difference before and after charging is maintained at a relatively low level, and the heat generation is not high.
2. Huawei mobile phones rank TOP10 in terms of calorific value
When charging the Huawei P50 Pro, the smart Phantom #3 has the best heat control, with a temperature difference of only 0.1 degrees Celsius before and after charging, which is very small. In addition, the NIO ET5, Feifan F7, Li L8 and Beijing Benz GLC, which ranked second to fifth, also have remarkable temperature control, and the temperature difference is controlled within 1 degree Celsius. Even the Mercedes-Benz EQS SUV, which ranks 10th, has a temperature difference of only 2.2 degrees Celsius before and after charging, which is still within a reasonable range.
Judging from the list, the temperature difference of the 10 models is within 3 degrees Celsius, and the heat generated by the mobile phone is not high. In particular, the temperature difference of the top 5 models is controlled within 1 degree Celsius, reflecting a good heat dissipation design.
Summary:
From the ranking of the above two test dimensions, it can be found that in terms of mobile phone charging, NIO ET5T, Li L7, Polestar 4 and Denza N7 perform relatively well overall, and all four models support Apple and Huawei fast charging protocols, and the compatibility is good. Among them, the performance of the NIO ET5T is relatively balanced, and the charging efficiency of the two mobile phones is not much different. In terms of mobile phone heat, the overall performance of the Audi Q4 e-tron, Beijing Mercedes-Benz GLC, and Geely Galaxy L7 is more prominent, and the temperature control of the two mobile phones before and after charging is relatively good. In addition, we also found that the Polestar 4 and Tesla Model 3 not only charge the Apple iPhone 13 Pro more efficiently, but also have excellent temperature control, reflecting the more practical wireless charging function of the two models.
