1, wireless charging than wired charging more damage to the battery. As long as it is charged, it will cause damage to the battery, but wireless charging and wired charging are compared, wireless charging will cause more damage to the battery, because wireless charging will generate more heat, and the heat generated will cause more damage to the battery. Whether the line charge charges the battery is controlled by the internal circuit of the phone, and the internal control circuit of the phone starts to work normallyThe voltage is provided by the battery.
2, wireless charging does not necessarily consume more power than wired charging. Wireless charging technology uses magnetic field induction to transfer power without the need for a physical connection (such as a cable), so it is considered a more convenient way to charge. However, this technology doesn't actually use any more power than wired charging.
3, whether it is wireless charging, or wired charging, as long as the battery exists charge and discharge behavior, there will be a certain loss. Wireless charging does not reduce battery life too quickly compared to wired charging. Of course, this premise is that you have to use with the device adaptationThe wireless charger. All in all, wireless charging is the same as wired charging, and we can use it with confidence. The loss speed of the battery is mainly related to the number of charges and discharges.
4, wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact. You said that the injured battery is wireless charging while playing will be far more than the wired battery, because the wired power supply does not use the battery, and the wireless is charging while discharging. Long-term use of radio charging will not affect the phone battery.
5, wireless charger has an impact on battery life. Using a wireless charger can have an impact on battery lifeThe sound is mainly reflected in the following aspects: First, the wireless charger generates current through the electromagnetic field to charge the device, and the charging method may be slightly less efficient than the wired charging. This means that some heat may be generated during the charging process.
1. Remove the protective shell of Huawei P40 Wireless charging mobile phone Remove the hard plastic plate on the inside of the protective shell. The center position is a wireless charging receiving coil. Next to the coil is a black circuit board, usedReceive on wireless charging. The position of coil and circuit board inside the protective shell are hollowed out to reduce the thickness. Remove the coil and PCB board, and you can see that the component surface of the PCB board is coated with silicone heat conduction.
2, but the mobile phone screen is not a fall/non-slip product, different falling height, Angle and ground topography to the mobile phone damage will be different, it is recommended to film the mobile phone. However, Huawei p40pro is randomly affixed with a layer of TP protective film, this protective film is plastic material, affixed to the outside of the screen, can protect the screen from being scratched, but can not prevent the screen from breaking, it is recommended to change to a more fall-resistant tempered film.
3. Huawei p40 screen uses aluminum-silicon glass material, which has high strength. However, the mobile phone screen is not a fall-resistant/non-slip product, and the damage brought by different falling heights, angles and ground topography to the mobile phone will be different, it is recommended to film the mobile phone. However, Huawei p40 is randomly affixed with a layer of TP protective film. This protective film belongs to plastic material and is affixed to the outside of the screen, which can protect the screen from being scratched, but can not prevent the screen from breaking. It is recommended to change to a more fall-resistant tempered film.
4, with its own film, Android new machines have their own film. But the film is just a soft film, there is no feel, andIts screw-set design allows for the replacement of power cords of varying lengths, demonstrating Apple's attention to detail and flexibility.
poe power poe and lan port The lan port connects to the router. The two ports of the poe power supply are connected to the poe and lan ports. The lan port is connected to network devices such as switches and routers. The poe port is connected to devices with the poe power supply function and AP antennas (with the WIFI frequency band communication function). Therefore, the poe power supply and lan port connect the lan port to the router.
Centralized power box: The centralized power box can power multiple cameras,The connection method is similar to the connection of a single power supply, but it has multiple ports and can connect multiple cameras. Array camera special power connection method Array camera power consumption, the need to use 2A power adapter nearby power supply, the connector with a power plug cut with scissors, cut for connection in the house on the plug, the broken end is connected to the monitoring power line.

The chip has been designed to support the inductive communication protocol of the Qi 4 specification and the Basic Power Profile (BPP).
1, synchronous rectification is a new technology that uses a special power MOSFET with very low on-state resistance to replace the rectifier diode to reduce the rectification loss. It can greatly improve the efficiency of DC/DC converter and notThere is a dead zone voltage caused by Schottky barrier voltage. Power MOSFET is a voltage controlled device, and its volt-ampere characteristics are linear when it is switched on.
2, synchronous rectifier circuit principle Synchronous rectifier circuit is a circuit that uses a method of synchronizing with the input voltage or current to achieve rectification. It usually consists of a converter and a rectifier. The converter can convert alternating current into direct current, while the rectifier can remove the instability in the output voltage or current. This method improves efficiency and can be used to control the amplitude and phase of current or voltage.
3, synchronous rectification is to change the secondary side rectifier diode to use MOSFET rectification to improve efficiency.
4, synchronous rectification technology is a kind of power conversion technology, can control the circuit switch, optimize the circuit topology and current sampling, etc., to achieve effective power control and optimize the conversion efficiency. Compared with traditional asynchronous rectification technology, synchronous rectification technology can more accurately control the current, make full use of battery energy storage, reduce energy loss and conversion loss, resulting in higher energy efficiency and longer battery life.
5, when the power MOSFET is used as a rectifier, the grid is requiredThe voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification.
