What are car front and rear mounting?

Pre-assembly refers to the parts that have been assembled before the car leaves the factory, such as wireless charging devices, etc. These parts are generally provided directly by the car Oems. Afterfitting refers to the parts added or replaced by the owner or dealer after the car is sold, such asSuch as the installation of cargo supports.

Front installation: refers to the host manufacturer for the vehicle factory to do supporting, similar to brake pads, three filters, wipers, most of these are accessories factory to support. After installation: refers to the product produced by the host manufacturer through the dealer to go through the volume, mainly to channel sales.

Automotive front loading and rear loading are two different concepts in the automotive industry. Front installation refers to the support provided by the Oems for the Oems, such as brake pads, three filters, wipers and other accessories. These products are usually supplied by the parts factory and are part of the complete vehicle assembly process, so the system stability is more guaranteed. After installation refers to the main engine factoryProducts sold through distributors are mainly sold through channels.

Front load configuration! That is, at the factory stage of the new car, the main engine factory carries out a series of pre-installation operations on the whole car, covering brake pads, three filters, wipers and other accessories. These parts are mainly provided by professional parts suppliers, and after rigorous inspection and confirmation, they are pre-assembled on the vehicle. The significant advantage of front-loading products is their system stability, which is guaranteed through rigorous testing and verification.

is divided into two ways: front loading and after loading. Generally speaking, the front installation means that the car is equipped with a wireless charging device before leaving the factoryGenerally located in the central storage box, armrest box location, the mobile phone can be charged on the charging device. The rear installation is to install an additional vehicle bracket and other devices on the car to achieve wireless charging, the installation position is not fixed, can be installed in the air conditioning vent, the car center console and other positions, or with the help of suction cups adsorbed on the windshield.

Front loading and rear loading are two different sales methods of auto parts. Front installation refers to the host manufacturer to provide supporting parts for the vehicle factory, such as brake pads, three filters, wipers, etc. Then assembly refers to the products produced by the host manufacturer are sold through dealers. When modifying a car, note is required

Wireless fast charge is not fast Wireless charge grade certification , nor is it slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.

In general, the conversion efficiency of car wireless chargers is limited, but throughReasonable choice of chargers, we can improve this situation. Although the speed of wireless fast charging is not fast, it is not too slow, and consumers should pay attention to the power and actual charging efficiency of the charger when purchasing.

But for the charging of the most basic requirements of the speed can not be reached, then the experience will probably be a discount. The wireless charger on the market, most of the charging chip components are from the QI standard, this standard provides electrical energy conversion power is billed as 5W, but because of its own low energy conversion rate, the actual application power is often only 5W-4W.

In addition to convenient advantages, wireless chargingThe disadvantages are many. For example, the charging time is too slow, the Samsung Note 5 is full for at least 6 hours Wireless charging level certification ; If you use a fast charge, it will be full in a little more than 2 hours. Although wireless charging also supports fast charging now, it is still not as fast as wired charging, after all, wired charging already supports 40W fast charging, and wireless fast charging is only 15W.

If the cross-brand change to Huawei mobile phone, Apple mobile phone, this wireless charger may not make much sense, or slow charging or incompatible, charging stability and charging efficiency are greatly reducedAnd some can damage cell phone batteries. So weigh, wireless charging start value is not high.

In daily life, compared with wired charging, wireless fast charging although there is no mobile phone charging head inserted into the charging cable connector easy to break concerns, but the charging speed is still too slow, and at the same time in wireless charging, can not play mobile phones, especially can not play too much power-consuming applications, should be the wireless fast charging rate is very slow. In this case, the choice is definitely limited charging, because the speed is fast, and you can play with the phone while charging.

What is the significance of NFC supporting 1W wireless charging?

1, such a low charging power want to charge the mobile phone must be wait until the monkey horse, after all, NFC is not designed for charging, so this wireless charging scheme is more to low-power IoT devices, such as smart watches, fitness trackers, wireless headphones, digital pens and other consumer devices. It doesn't make much sense for high-consumption electronic devices like phones or pads.

2, then, what is the significance of NFC wireless charging? 01 Small devices can be charged directly wirelesslyNFC wireless charging can be used for wireless charging of small battery-powered devices (such as IoT devices, wireless headphones, smart watches, smart bracelets, etc.), without the need to redesign the charging unit separately.

3, I think that NFC support wireless fast charge on the mobile phone is more likely to affect the mobile phone integration NFC module, in the future, there are more supporting devices can achieve charging life through the mobile phone, greatly enrich the application scenario of the mobile phone.

4, it does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large. Wireless charging and reverse wireless chargingHas become a common feature on high-end mobile phones, which use dedicated coils for radio energy transmission. Now the NFC Forum has announced the approval of a wireless charging specification that will allow users to wirelessly charge devices via NFC chips.

Wireless charger radiation big or mobile phone?

Reporter conducted a test wireless charge grade certification , the results show that the wireless charger does exist radiation, although the value is small but not without. Tests show that the wireless charger spokeThe radiation value is smaller than that of mobile phones, such as Sharp SH8010C and Samsung i579, but when used with other electronic devices such as computers and WiFi, the cumulative effect cannot be ignored. In extreme cases, values above 2,500 can have a significant impact on health.

First answer is it wireless charging level certification : Yes. The working power of the wireless charger is larger than that of the mobile phone, and the electromagnetic field energy radiated by the wireless charger is larger than that of the mobile phone.

Conclusion To reiterate: Although the radiation from wireless chargers is small, the cumulative effect may have health effects, therefore,While enjoying wireless convenience, users need to remain vigilant and try to control the superposition of radiation sources to protect their own health.

Radiation is certain, otherwise the energy cannot be transmitted through space. The radio waves used for charging must be larger than the radiation power of the phone itself, otherwise the charging efficiency is too low. Calculated with a 1000mAh capacity lithium battery, 50% of the charging capacity is about 7~8Wh.
