Electric vehicle charging extension cable how to match: introduction to promote basic charging every day car wireless charging material , so that the battery in a shallow cycle state car wireless charging material , battery life will be extended. In the process of using car wireless charging material , the charging time and frequency should be accurately mastered according to the actual situation. Overcharge, overdischarge, and undercharge will basically reduce battery life. Prevent plug from heating up while charging. If the heating time is too long Car wireless charging material , will affect the plug short circuit or poor contact, damage the charger and battery.
Electric vehicle charging line 5 square and 4 square can be. If from the price point of view, the short distance is recommended to use 4 square, because the price and 5 square is not much different. If the distance is too long, the problem of charging current must be considered.
The first principle of purchasing a charging cable is safety. Therefore, it is recommended that riders choose big brands and products with guaranteed quality. Charging cable choose four square copper wire. Riders are not advised to choose 5 square, in theoryPool damage; And the electrical conductivity of the glass is almost zero, which means that too much heat will not be generated in the process of wireless charging. Signal transmission.
3, Apple is the rear glass is to improve the signal of the device, the metal shell will have a certain impact on the signal of the device. Today's mobile phones have a common appearance, that is, the back cover of the mobile phone is all made of glass design, and from high-end to low-end, many models have adopted this design. Glass has a better signal than other materials, and metal can reflect the signal, causing problems with signal reception.
4, in addition to the glass bodyA large number of advantages, such as not easy to occur paint, corrosion and other problems, and tempered glass will not occur after the shell scratch problem, with the development and growth of the glass body, now can be converted into a variety of beautiful colors, to promote the mobile phone shell more and more beautiful.
5, in theory, glass will not block wireless transmission, but because the glass is thick, it may reduce the efficiency of wireless charging.
6, due to the material reasons, the metal for the signal obstruction is relatively large, and the glass for the signal obstruction is relatively small, the use of glass body material of the mobile phone signal is more than the metal body materialYes. Secondly, in the field of high-end machines, wireless charging has increasingly become a major selling point of mobile phone competitiveness, and mobile phones with glass body materials are more suitable for wireless charging.
