1, electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, the problem of battery life has not stopped, in order to solve the battery life problem, the various car companies have also tried their best to find a way to solve this problem, in addition to change the power and fast charge, in fact, there is a different way, that is, road charging, Let the car run along the road.
2, Tesla acquired the German WIFERION, in the modified version of the Model 3 application of wireless charging technology, behind the logic is electromagnetic inductionLine charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
3, it is reported that at present, the mainstream car companies at home and abroad have laid out the wireless charging technology of automobiles, and the state has also promulgated the "electric vehicle wireless charging system Part 1: General requirements" and other four national standards; The "New energy Automobile Industry Development Plan (2021-2035)" also points out that it is necessary to strengthen intelligent and orderly charging, high-power charging, and non-chargingResearch and development of new charging technologies such as wire charging.
4, for electric vehicles with wireless charging, mostly through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, through the magnetic resonance generated between the coils to replace the traditional power lines for vehicle charging. This charging method requires higher spacing between the supply and receiving coils. The huge demand for wireless charging technology for electric vehicles makes the research and development of related technologies quite active.
5, the wireless charging technology of electric vehicles, that is, through electromagnetic induction, magnetic resonance or radio frequency and other ways, to achieve non-contact power transmission without charging cables. This technique avoidsIf it is too low to stop charging, here are some suggestions for you: disconnect the phone from the power supply, end the program running in the background of the phone through the task manager, and wait for a while to try charging again. It is recommended to charge in standby mode; Replace other power supply position and recharge; Check to see if the phone is using the original battery.
Only need to support wireless fast charge mobile phones, smart watches, wireless headphones placed on the back of the Samsung S10, you can achieve wireless charging.
What is the IC of the mobile phone charger on the mobile phone motherboard? IC, or integrated circuit, is made using a semiconductor process in a smaller piece of monocrystalline siliconMany transistors, resistors, capacitors and other components are made on the chip, and the components are combined into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. It is represented in the circuit by the letter "IC" (also useful word symbol "N", etc.).
Mobile phone chip: the cpu is slightly larger, the square contact solder joint many models of manufacturers have larger font, at a glance IC: there are many kinds of, most of them are glass chips with display keyboard music photography, etc., fewer contact solder joints.
The upper half of the motherboard is the RF circuit, the lower half is the logic circuit, and the RF inside is oneThe largest is the power amplifier, the rectangle is the antenna switch, the following square is the middle frequency logic circuit in the largest is the cpu, next to the rectangle is the word library, the largest capacitor around the power supply.
The difference between ic and chip is mainly: chip is a general term for semiconductor component products; IC is an integrated circuit, which uses a semiconductor production process to make many transistors and resistors, capacitors and other components on a small monocrystalline silicon sheet, and combines the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. ic chip purchase recommended widely acclaimed Yunhan core city! Under theSingle account period service, first delivery after payment.
Generally, we will determine its IC through the mobile phone system! The chip is not what we ordinary people can judge! Enter *#06# when the phone is on standby and the phone will automatically pop up its unique message code! It has some basic information on it! To understand the meaning of the code on it please find another tutorial on Baidu.
In mobile phones, ics are usually used to process signals, store data, control power, etc. For example, the processor of a mobile phone is a highly integrated IC, which is responsible for performing the various calculations and operations of the mobile phone. The phone's memory coreChip is also a type of IC, used to store mobile phone system and user data. In addition, the phone's power management IC is responsible for controlling the charge and discharge of the battery to ensure the normal power supply of the phone.
1, the AP45851 uses a unique "CNS-chip as system" technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power devices during standbyDetection, Foreign body detection (FOD) for secure wireless charging. The high level of integration and advanced features help simplify the system design of application engineers, and the periphery is extremely simple, while greatly reducing the difficulty of PCB design.
2, play the role of metal isolation, prevent energy waste, improve charging efficiency.
3, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate the electromagnetic signal, and the receiving end coil is induced to generate the electromagnetic signal at the sending endThe current charges the battery.
