1. It's true. This way of charging is very fresh and convenient, but there are concerns about radiation. rightLine charging is mainly used in two ways: magnetic induction wireless charging and magnetic resonance wireless charging. The way electromagnetic waves are used in low-power places is not possible, let alone in the field of car charging. Whether it is magnetic induction or magnetic resonance, the final transfer of energy is the use of the space magnetic field, and because at least kW level of energy must be transferred, the energy level is large, then the frequency of the space magnetic field is correspondingly low.
3, electric vehicle charging methods are mainly divided into two kinds. One is the principle of electromagnetic induction, yes, it is the electromagnetic induction of junior high school physics, the principle is very simple, but rely on this originalThe reason for wireless charging is a matter of recent years, and mobile phones such as the lumia 920 officially introduced this technology to the mobile phone industry in 2012.
4, wireless charging technology, that is, wireless power transmission technology, is a non-contact power transmission method. Mainly through electromagnetic induction, magnetic resonance, radio frequency, microwave, laser and other ways to achieve. At present, the wireless charging methods of pure electric vehicles are mainly electromagnetic induction and magnetic resonance. The electromagnetic induction type is mainly used to fix the parking space, while the magnetic resonance type can charge the vehicle while moving.
This technology is to allow electric vehicles to drive on a dedicated highway, through the magnetic field resonance between the road and the electric vehicle during driving, to achieve wireless charging of electric vehicles, just like our mobile phones can be charged while playing. In this way, the range of electric vehicles can be greatly extended, breaking through the current technical bottleneck of short battery life of electric vehicles.
Wireless charging transmission Nowadays, small electronic devices such as mobile phones and washing machines can be charged wirelessly. Highway wireless charging systemThe system works by burying a series of coils with an electric current under the highway, and then installing induction coils at the rear of the car. When the car passes through this section of road, magnetic resonance is generated, which makes the car constantly charged. But what this approach needs to address most is cost. After all, this method is expensive and expensive to maintain.
Then, if the car can also be charged wirelessly, that is, stop charging, and even charge while running, so that does not solve the major pain point of electric vehicles now? Recently, the Ministry of Industry and Information Technology issued regulations to raise the charging power limit of mobile phones and other mobile devices to 80W, and apply wireless charging technology to electricCars. This means that the era of wireless charging for electric vehicles may be coming. At present, pure electric vehicles are the trend of the next 20 years, so these two charging technologies are not impossible to achieve. The premise is that the solar charging technology is greatly improved and the cost of highway charging technology is greatly reduced. This article is from the author of the car home number and does not represent the viewpoint of the car home.
Among them, dynamic wireless charging means that the energy is transferred to the bottom of the vehicle through the ground sensing device during the driving process to achieve charging. Static wireless charging, on the other hand, transfers power to a road near the vehicleOn the sensor board, the vehicle can be charged after entering the sensor area. Wired charging is the traditional way of charging, which requires the charger to be connected to the electric vehicle to complete the charging.
Wireless charging and wired charging each have advantages Intelligent electric wireless charging , which is better to choose depends on the specific use scenario and needs. Advantages of wireless charging: Convenience: Wireless charging does not require inserting or pulling out the charging cableWireless charging , just put the device on the charger to start charging Intelligent electric wireless charging , very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.
Wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface, so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless chargingYou need a wired charger, too, and a wireless charging pad.
Cable charging is good. In the case of the same charging time, the power of the commonly used wired battery charger is 93% after charging, and the power of the wireless charger is 88% after charging. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
Tai Ling is also one of the earlier intelligent electric wireless charging , released the brand with wireless charging electric vehicle products Intelligent electric wireless charging , The Taiwan Bell N9 super smart version is equipped with InnoGaN's new wireless charging intelligent electric wireless charging , charging is very convenient, in addition, it can also increase the charging efficiency by 60%, support 1 hour fast charging, so that the owner does not have to wait for a long charging time.
The Yadi Crown T7 is a classic long rangeThe model, the appearance is very classic. The biggest highlight of the car is its support for fast charging, which takes only three hours to full. In addition, the car is equipped with a 1200W high-power motor and 72V38AH large-capacity graphene battery, with a maximum driving range of 200 kilometers. In addition, the car is also equipped with a large seat bucket design and USB charging design for mobile phones, which is very practical.
Changan Auchan Z6 Intelligent electric iDD is a compact plug-in hybrid SUV, equipped with Blue Whale NE 5T engine 24KWh large-capacity battery pack, the whole series of pure electric range of 150 kilometers, full of fuel and full chargeThe range is 1200 km.
