But the advantages of wireless charging are also very obvious. Since there is no need to plug and unplug the charging gun, the convenience of charging is significantly improved, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method usesInduction type. High-power wireless charging High-power wireless charging usually adopts a resonant mode (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation. Overall, while the idea that electric cars will never have to be recharged again is appealing, it's still a beautiful vision given the current technology and market environment. We look forward to the development of technology in the future to bring more possibilities, but at present, charging is still an essential part of the use of electric vehicles.
Secondly, wireless charging technology wants to be truly popular, and it also has high requirements for the precise positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of precise positioning, the same footprint, the number of electric vehicles using wireless charging compared with the traditional charging pile charging will be greatly increased, greatly improving the space utilization and charging efficiency.
To achieve efficient energy transmission. The advantages of this method include high efficiency, long distance transmission and security, but the technical requirements are highThis is also relatively high, and has not yet been applied on a large scale. In general, wireless charging technology is showing broad development prospects, is expected to become the mainstream of electric vehicle charging. However, technical difficulties and cost issues are still the key issues that need to be solved, which requires continuous innovation and improvement by researchers.
If it is equipped with wireless charging function, Ioniq 7 will have stronger product competitiveness. Although it is difficult to see the large-scale application of wireless charging for electric vehicles at present, such a technological application needs to have the first crab if Hyundai Motor can widely apply it in its ownOn electric models, it may lead other brands to follow up, and wireless charging may become the standard of electric vehicles in the future.
Wireless charging of new energy electric vehicles is distinguished from the basic principle, mainly electromagnetic induction and magnetic resonance. The research of electromagnetic induction focuses on inductive charging, wireless charging, electromagnetic induction and charging station. The research of magnetic resonance focuses on the fields of wireless power supply, resonance frequency, induction coefficient, antenna and transmitter. Zte, BMW, Mercedes-Benz, etc., adopt the principle of electromagnetic induction technology, Qualcomm Halo, Witricity adopt the principle of magnetic resonance technology.
Wireless charging can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, such as mobile phone charging. High-power wireless charging often uses magnetic resonance, and the power supply device (charger) transmits energy to the power device, which uses the received energy to charge the battery and at the same time for its own operation.
At present, there are three types of wireless charging methods:Electromagnetic induction type, magnetic resonance type, radio wave type.
Wireless charging mainly includes power factor correction (PFC), ground coil, vehicle coil and other parts, should belong to the direction of automotive electronics and power electronics.
Fast charging: at present, the technology of fast charging is still limited, but in the last year, the charging pile has appeared fast charging. Generally, it can be filled with about 80% of the electricity in ten minutes. It is expected that by the end of this year, this technology will be widely used when the battery of the vehicle will be further optimized to meet the fast charging box wireless charging; Replace the battery: Replace a fully charged oneThe battery can keep the car going.
With wireless charging technology, electric or dual-energy vehicles driving on the road can be quickly replenished by transmitters mounted on telephone poles or other tall buildings. The electricity bill will be deducted from the prepaid card installed on the car. In addition to the above charging methods, you can also replace the battery pack, that is, when the battery runs out, replace the depleted battery pack with a fully charged battery pack.The application prospect of super battery is wideWide. With the popularity of high-tech products such as electric vehicles and drones, the demand for high-performance batteries is also increasing. As a high energy density, fast charging battery technology, super battery has great market potential. In the future, with the continuous development and improvement of technology, super batteries are expected to be applied in more fields, bringing more convenience and innovation to people's lives.
The advent of super batteries is expected to greatly improve the endurance and charging efficiency of new energy vehicles, so as to effectively make up for the shortage of lithium batteries. However, the superbattery is not perfect, and the market is still controversial about its use effect, which showsThere may be some limitations. Therefore, the future battery market will offer a variety of options. In 2021, a number of companies launched new high-efficiency batteries in an attempt to occupy the power battery market.
The market size of this super battery is not less than $1 trillion. At present, the United States, China, Japan and South Korea are rushing to super batteries. The currently commonly used lithium-ion batteries were commercialized in 1991, and there are mainly three types of lithium cobaltate, lithium iron phosphate and lithium manganate. Lithium cobalt acid battery has the highest energy density, but it is unstable at high temperatures, and the other two energy densities are not high.
is expected in the next decade, the global on lithiumThe demand for batteries will increase significantly, and the market value will also increase. Overall, although supercapacitors show potential to replace lithium batteries in some areas, the possibility of fully replacing lithium batteries in the short term is still limited.
The prospect of supercapacitors in the field of new energy has attracted much attention. Although it has been developed for many years, its application is still limited by the dominant position of batteries, and high cost and technical difficulty are the main problems. However, once the technology breaks through, supercapacitors have the potential to give a major boost to the new energy industry. At present, micro supercapacitors are widely used in computer memory systems, cameras and other small devicesLarge capacitors show potential in automotive and energy harvesting.
Wireless charger needs to be charged. Wireless charger, as the name suggests, is a charging device that can provide electrical energy to electronic devices wirelessly. When we use wireless chargers to charge other devices, we need to ensure that the wireless charger itself is sufficient. Therefore, in order to ensure the continuous work of the wireless charger, we need to charge itself regularly.
Apple mobile phone wireless chargingElectrical appliances need to be charged, Apple wireless charger is a wireless charging device, there is no battery inside, in use, to plug into the mains, because it has no battery inside, not a charging treasure, so as long as the phone is charged, plug into the mains to charge the Apple phone or watch.
Wireless charger refers to the charger that does not use the traditional charging power cord to connect to the terminal device that needs to be charged, using the latest wireless charging technology, wireless charging technology obtained 20 patents in 2007, a variety of devices can use a charging base station, mobile phones, MP3 players, power tools and itsThe wired charging of his power adapter will no longer exist.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Huawei Super Fast Charge wireless charger does not need to be charged, plug and play.
In theory, it is possible to plug the wireless charger when it is not used, the wireless charger is designed to be convenient to use, but if the user does not use the wireless charger to chargeWait, it is best to choose to turn off the power. For mobile phones that support wireless charging, just place the phone in the middle of the wireless charger to charge the operation, which is relatively convenient.
