Wireless bidirectional fast charging is a new charging technology that can be used in a variety of scenarios such as mobile devices and electric vehicles. It can charge quickly, supports two-way transmission, and does not require the use of traditional chargers and cables. This technology is based on the principle of electromagnetic induction, by wirelessly transmitting electrical energy to the device to charge. When the internal charge of the device is full, the excess power is reversely transmitted back to the charger.
Bidirectional fast chargingThis means that both the output and input support fast charging; The output supports fast charging, that is, when the charging treasure charges the mobile phone, the charging treasure and the mobile phone support fast charging, and the input supports fast charging, that is, when the charging treasure charges the charger and the charging treasure support fast charging. At present, the charging speed is generally 5V, 2A is the base benchmark, the charging power exceeds 5V, 2A is the concept of fast charging, in principle, it is also divided into two directions of pulling high voltage and increasing current.
November 25 news, this afternoon Huawei officially released its new MatePad Pro tablet computer, Yu Chengdong introduced this tablet computerMentioned that this tablet is the first two-way wireless charging tablet. Huawei MatePad Pro is the world's first two-way wireless charging tablet, equipped with 7250mAh large-capacity battery, support 40W super fast charge 15W forward wireless fast charge, 5W reverse wireless fast charge technology.
Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology transmits energy by magnetic field between the charger and the electrical device, bothThere is no wire connection between them, so the charger and the device that uses electricity can be exposed without conducting contacts.
Wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end coil is connected to the wired power supply to generate electromagnetic signal, the receiving end coil induction electromagnetic signal to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
Wireless fast charging is actually a function, yesUrgent charging includes two forms of charging station and mobile recharge trolley, mainly through the non-on-board charger using high current to directly charge the battery, so that the battery can be charged to about 80% of the electricity in a short time, generally 1 hour can be fully charged.
After the first ride, do not charge the electric car immediately, but park the car for half an hour, and then choose to charge, which is more conducive to the cooling of the battery, as well as the protection of the battery. Finally, users also need to pay attention to the first charge, after the charger jumps the green light, do not immediately unplug, you can continue to charge for 40 minutes, which is more conducive to the battery into the best state.
When charging, the output should be connected to the electric vehicle and then plug in the power supply to charge. Vice versa, when charging is complete, unplug the power supply and then the output connector. It usually takes 8-10 hours to charge the battery. With the electric vehicle charger after the green light and then add 2 hours as the benchmark charging, the first tram charging, after the power source is exhausted, on the basis of full charge can be charged for two more hours. It is best not to "throttle" the electric car when it starts.

1, the way of charging new energy vehicles on the high speed is as followsThree kinds: wireless charging, also known as inductive charging. The biggest feature of this charging method is safety. Even in rain and snow, there is no need to worry about the risk of electric shock. Car charging case. When the car is idling, the on-board charging box can charge the battery. Charging pile in high-speed service area.
2, the charging method of new energy vehicles is mainly divided into two kinds: one is to charge through the public charging pile, the other is to use personal charging equipment. Both approaches are described in detail below. Charging with public charging piles: As of August 2019, with the increasing number and brand of new energy vehicles, public charging piles have been establishedExtensive Settings. When charging in public charging piles, fast charging and slow charging should be distinguished. 3, First of all, wireless charging, also known as inductive charging, its biggest advantage is security. Even in harsh weather conditions, such as rain and snow, there is no risk of electric shock. Secondly, in-car charging boxes are another convenient option. When the car is idle, the on-board charging case can replenish the battery. Finally, charging piles in high-speed service areas are the most common way of charging at present.
4, the first is wireless charging, also known as inductive charging. This way is very safe, even in badIn weather, you don't have to worry about the risk of electrocution. The second is the car charging box, which is the key to emergency charging. When the car is idling, the on-board charging box can charge the electric car. This approach is very important on long distance sports cars.
5, how to charge new energy vehicles on the highway is the key point. The State Grid Corporation has led the construction of charging piles along most highways, and charging facilities between some major cities have been relatively complete. ! Before the owner of an electric vehicle travels, the first task is to make detailed planning, especially according to the mileage of the vehicle, timely estimate and find the charging pile locationBuy.
6. How to deal with the power depletion of new energy vehicles at high speed? In this situation, the first thing to understand is that if you break down halfway, you may need to use a towing service to move the vehicle to the nearest charging facility. However, due to the particularity of the highway, charging in the emergency lane is usually not allowed, which will lead to a longer charging time.
1, in general, the conversion effect of car wireless chargerThe rate is limited, but by rationally choosing chargers, we can improve the 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.
2, wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger energy conversion rate is still very high, more energy saving.
3, low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless than wired" in the application way, but forCharging the most basic requirements of the speed can not be reached, then the experience will probably be a discount.
4, wireless charger under normal circumstances is not harmful to the mobile phone, wireless charging now the working frequency is below 1M, so the signal of the mobile phone will not have an impact on the battery life of the mobile phone, and wired charger, but in terms of speed will be lower, but the conversion rate of wireless charger is high. It can save energy more.
5, do not need wired interface, many products can be made into fully enclosed waterproof products.
6, the conversion efficiency is highThe current mobile phone wireless charger conversion efficiency is more than 60%-80%. Under the same conditions, the higher the efficiency, the faster the charging speed. But efficiency is not the only factor that determines charging speed. Some manufacturers with strong technical strength improve chip performance, optimize program design, and adjust the current output so that the speed of wireless charging can match or even exceed the speed of wired charging.
