Today to share the knowledge of the car wireless charging test, which will also explain the car wireless charging chicken ribs, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>1, In the early test of wireless charging buses in South Korea, it was found that the distance between the two is more than 1CMOnly 80% of the electricity is transmitted, and if it is separated by 12CM, only 60% of the electricity is transmitted. If you can transmit power over a longer distance and can transmit more power, it is necessary to talk about another medium-range wireless charging technology, which can transmit energy over a longer distance.
2, however, for the wireless charging system, the charging efficiency and the distance between the transmitting coil and the receiving coil, position deviation, etc., once the position of the two coils is slightly wrong, it will seriously affect the wireless charging efficiency, and can only achieve one-to-one charging.
3. It's not just the dayAt the end of last year, Stellantis, the world's fourth largest automobile manufacturer, announced on its official website that their innovative dynamic inductive charging technology has proved successful after years of research and months of testing. The road "Arena del Futuro" for wireless car charging testing has been officially opened. So now wireless charging technology is also a very hot ranks. 4, it is worth mentioning that recently issued by the Ministry of Industry and Information Technology "Wireless charging (power transmission) equipment radio management Interim Provisions", clearly mobile phones and other mobile devicesThe charging power limit is increased to 80W, and the regulation also applies to wireless charging of electric vehicles. This has undoubtedly injected new impetus into the development of wireless charging technology for electric vehicles. In short, electric vehicle wireless charging technology still faces many challenges, but its development prospects are broad.
5, wireless charging can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, such as mobile phone charging. High-power wireless charging often uses magnetic resonance, and the power supply device (charger) transmits energy to the electrical device, which uses the received energyThe battery is charged and at the same time used for its own operation.
minutes reaches or exceeds 10%, and the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the Deep Blue SL0 Long comfortable Da and Wei brand Blue Mountain DHT-PHEV are obviously not too friendly for Apple iPhone 13 Pro, with a 15-minute charge of 3%, which is a large gap compared with other test models. <"Wireless charging Systems for electric vehicles - Part 2: Communication Protocol between on-board chargers and charging devices" (GB/T 38772), "Wireless charging systems for electric vehicles - Part 3: Special Requirements" (GB/T 38773), "Wireless charging systems for electric vehicles - Part 4: Electromagnetic environmental limits and test methods (GB/T 38774) a total of 4 national standards.
The highest charging efficiency of Xiaomi and Huawei requires the mobile phone to support its own protocol, so we separately tested Huawei Mate 30 with Huawei WirelessCharging mobile phone stand and millet 10 with millet wireless charging mobile phone stand. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is to keep the phone lit, and test the time required to charge 10% (from 40% to 50% of the phone charge) on all products under test.
The configuration of the two models of the leading PHEV is quite rich, and the high-equipped models we tested can be described as luxurious. Inductive trunk, mobile phone wireless charging level is relatively rare configuration. In fact, in Beijing Hyundai less than 100,000 low-end modelsIt has already been equipped with mobile phone wireless charging to cover almost all models.
Because the iPhone does not pay enough attention to wireless charging, several generations of iPhone mobile phones do not support wireless charging. Make fruit fans very sorry! Now, Apple fans can use wireless charging on the iPhone7Plus without waiting for the next iPhone7. Resistance toErkin car magnetic wireless charger II generation, specially tailored for the iPhone7Plus special version, can support the iPhone7Plus wireless charging, and is the car's wireless charging.
Take ios12 version as an example, iphone7plus does not support wireless charging, iphone products only iPhone 8 above support wireless charging, wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways, mobile phone charging is low-power charging.
There is no wireless charge in the iphone 7 plus box
