Can electric vehicles achieve wireless charging in the future like mobile phones? Of course you can! Don't talk about the future. It's already here. The electric cars produced by BMW can already be charged wirelessly. onlyThe driver is asked to move the car over the wireless charger and the system automatically charges the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future.
Wireless charging also faces a cost problem. Although the current SAIC Roewe, BAIC New Energy, BYD and other mainstream car manufacturers are developing and testing electric vehicle wireless charging technology, but the cost of this technology is still high. Although there are currently no domestic production models that support wireless charging, this is expected to change soon.
Then if the car can also be wirelessCharging, that is, stop charging, and even charge while running, which 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 electric vehicles. This means that the era of wireless charging for electric vehicles may be coming.
It is worth mentioning that the "Interim Provisions for Wireless Charging (Power transmission) equipment radio Management" issued by the Ministry of Industry and Information Technology recently clearly raised the charging power limit of mobile phones and other mobile devices to 80W, and stipulated that the management provisions also apply to the wireless charging of electric vehicles. This is undoubtedly an electric carThe development of wireless car charging technology has injected new impetus. In short, electric vehicle wireless charging technology still faces many challenges, but its development prospects are broad.
Most of today's mobile phones support wireless charging. You just need to put the phone on the wireless charging pad and charge it. Although the speed of wireless charging is slower than that of wired, wireless charging is simpler and faster to a certain extent.
Zhiji Automobile and Ningde Times, using the latest battery technology, will take the lead in the global application of silicon doped lithium cell battery technology. The battery technology has the highest energy density in the world, can support a maximum of nearly 1,000 km of battery life, and achieve an ultra-long 200,000 km zero attenuation performance to eliminate users' anxiety about range and battery life.
It is reported that SAIC will equip the world's first 11kw high-power wireless charging on the Zhiji car, charging for one hour, can achieve a range of about 80km. As we all know, wireless charging technologyThe biggest problem in the application is that the charging speed is slow, and the placement requirements are strict, so how does the Zhiji car do it? It is reported that the wireless charging of Zhiji cars will be combined with fully automatic autonomous parking technology to solve the problem of alignment, without driver operation, to achieve non-inductive recharge.
At present, limited information can be learned, and the official name has not yet been announced, but the official revealed that the mileage of the Zhiji car is nearly 1000km, and the sword has just released the NiO ET7. In the official news, the details that can be obtained are a new battery technology, which is jointly developed by SAIC and Ningde Times, known as blendingSilicon lithium battery technology, known as never spontaneous combustion and equipped with the world's first mass production equipment 11kW high-power wireless charging.
Intelligent light with eye movement, pedestrian reminder, etc. The whole series of Zhiji car is equipped with 93kWh battery and 115kWh battery, the driving range is 874km, and the first use of silicon supplement lithium technology. The battery is committed to "never spontaneous combustion", and is equipped with the world's first mass-produced equipment 11kW high-power wireless charging. The power adopts intelligent dynamic four-wheel drive system, the rear axle is the main drive, the maximum power can reach 400kW, the peak torque is 700N·m, and the acceleration of 100km is only 9 seconds.
1, Chongqing high power noneThe core of the principle of wire charger is energy transmission through the principle of electromagnetic induction. Specifically, the wireless charging system consists of two parts, namely the charger and the receiver. The charger converts electrical energy into a high-frequency electromagnetic field, while the receiver converts the electromagnetic field into electrical energy through an induction coil to achieve the process of charging. In the principle of high-power wireless charger, there are several key elements to consider.
2, in fact, wireless charging technology is not a tall technology, it is the use of electromagnetic induction principle or magnetic field resonance principle, to achieve wireless transmission of electric energy. This technology has been around for a long time. It's justThe application in the car is relatively late, and the wireless charging of mobile phones in the car fire in recent years is an important selling point of car companies.
3. At present, ZTE's wireless charging scheme has been officially put into use in some cities. Contrary to ZTE's well-known reputation, BYD is said to have applied for a patent for a contact-free inductive charger in 2005 and equipped a WAVE wireless charging pad on a pure electric bus sold to the University of Utah in 2014. As for the representative of the scientific research institutions, Chongqing University is said to have started research in 2002 on a "high-power radio energy charging transmission device" for charging cars.
4, this time, OPPO MagVOOC magnetic wireless charging bank supports 20W wireless charging power, and by adding magnet auxiliary alignment, solve the user's difficult to align when using wireless charging pain points, in non-working state can automatically switch to low power mode; Moreover, the magnetic wireless charging bank has no physical button, which can detect the situation of the mobile phone and start charging, greatly improving the convenience of daily use for users.
5, the business scope of Chongqing Fugui Electronics Co., Ltd. is: production, operation, development of wireless modules, wireless chargers, wireless network streamers, trackers,
