1, UKCA certification (UK Conformity Assessed) is the proposed labelling requirements for products in the UK. Products released into Great Britain (" GB ", which includes England, Wales and Scotland, but excludes Northern Ireland) will replace the EU CE marking requirement. The UKCA marking will indicate that products released into the UK Great Britain region meet the UKCA marking requirements.
2, ukca certification is UK Conformity Assessed (UK Conformity Assessed) is put on the market in the United Kingdom (England, Scotland and Wales)The UK product marking requirements required for the products replaced the EU requirements for CE marking (CE marking will continue to be accepted in Northern Ireland). The UKCA mark will indicate that products placed on the UK market meet UKCA certification requirements.
3, UKCA certification is the abbreviation of British conformity certification. UKCA is the product marking used to replace the EU CE certification mark after Brexit, covering most goods that previously required CE marking, it applies to goods placed on the market in the United Kingdom (England, Wales and Scotland, but not Northern Ireland), and also applies to goods that previously required a "reve.Line charger '> UK university develops remote magnetic gear electric vehicle wireless charger
1, British well-known universities innovative wireless charging technology: remote magnetic gear electric vehicle charger! A research team at the University, led by Professor Lorne Whitehead, has launched a revolutionary wireless charging solution - a wireless charger for remote magnetic geared electric vehicles. Its core technology is a charging system called "Remote Magnetic gear," which is cleverly designed and efficient.
2, the scientific research team of the University of British Columbia has made a major breakthrough in the field of wireless charging and launchedInnovative technology - remote magnetic gear. This system has injected a strong impetus into the field of electric vehicle charging, providing an efficient and convenient charging experience through a unique remote charging method. The core of the "remote magnetic gear" system is a pair of rotating magnets. Install one on the charger and one inside the electric vehicle. 3. Recently, Professor RON Whitehead from the University of British Columbia has developed a wireless that uses a "remote magnetic gear" instead of an electromagnetic coil, allowing people to charge batteries while sitting in a car. This wireless charging system has been put into use in this "wireless charging station" wayThe so-called "remote magnetic gear" is actually a pair of continuously rotating magnets, one is installed in the charger, and one is installed in the car. 4. Practice has proved that the charging efficiency of the wireless charging system can reach more than 90% of the wired charger, and the electric school bus can be fully charged in only 4 hours. Recently, Professor LorneWhitehead from the University of British Columbia developed a remote charging system called "Remote Magnetic Gear", which is currently only used for electric vehicle charging. The "far magnetic gear" is a pair of rotating magnets, one of which is mounted inside the charger and the other is mountedIn an electric car.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging is also known as inductive charging, non-contact senseCharging, derived from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the power coil)Near this magnetic field, an electric current is generated to charge the phone. As shown below.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
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.
1. With the continuous progress of science and technology, electric vehicles have gradually become the best choice for green travel around the world. However, the charging problem has always been the focus of car owners. Recently, the UK has taken the lead in launching a pilot project for wireless charging of electric vehicles, aiming to break this bottleneck and bring real convenience to owners. The UK's innovative "dynamic wireless power transmission" technology enables wireless charging during vehicle driving, completely solving charging anxiety.

In addition, Hyundai Motor has applied WiTricity's technology in the development of its E-GMP platform for electric vehicles, and is expected to introduce wireless charging on the Hyundai Ioniq 5 in the future.
4, recently, NIO Automobile announcedPatent application information on "Wireless Charging System and wireless charging Method for vehicles". The patent information shows that the wireless charging system includes: a charging transmitter, which is arranged on the side of the charging area and is used to convert electric energy into electromagnetic energy; The charging receiving device, arranged on the upper part of the vehicle, is used to receive electromagnetic energy to convert electromagnetic energy into electric energy for storage; And the first drive device, the second drive device, the control device, etc.
5, many people have not enjoyed mobile phone wireless charging, wireless car charging again. Recently, the China Electricity Council (CEC) approved and released a set of wireless charging for electric vehiclesThe standard is based on the magnetic resonance wireless charging technology developed and patented by WiTricity in the United States.
