1, 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.
2, secondly, wireless charging technology wants to be truly popular, and the precise positioning and intelligence of vehicles are also highThe requirements of. 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.
3, 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 uses induction. High-power wireless charging High-power wireless charging is often resonant (most electric vehicles chargeThe power supply device (charger) transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
4, the wireless charging of electric vehicles is very strange to consumers, it is like we look at the concept car is a future scene. However, if it can be achieved, it can greatly alleviate the impact of inconvenient charging.
5. The race to build a universal wireless charging technology is in full swing. New and exciting wireless charging technology advances and products continue to emerge - some companies are focusing on one technology, tooSome companies support multiple technologies. But the lack of interoperability between the various technologies is still a big problem, because there is no unified wireless charging standard. The idea of wireless power transmission has been around for years.
6, compared with the traditional wired charging method, wireless charging with no charger connection, voltage stability, surge prevention and other advantages, has become an important development direction of EV charging. In addition to the advantages of convenience, safety, reliability and small footprint, it also has the following six advantages: Wireless charging of electric vehicles can improve information and intelligence and reduce labor costs.
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 electric coil) close to the magnetic field will generate current, charging the mobile phone.
Wireless charging transmitter input DC voltage (DC Voltage). The DC Voltage passes through the power bridge, producing an AC Voltage at SW1 and SW2, which is actually a square wave. Square wave loading generates an AC Current at both ends of the LC Tank. An alternating current passes through the coil to generate a magnetic field. The receiving coil senses this magnetic field and generates an AC Current in the receiving LC Tank. According to officials from the Wuhan Construction Bureau, a total of 60 such wirelessly charged street lights have been installed on Jianghan Road in Wuhan, with two for each street lampThe DC output is: 5V/2A. The MDY-11-EM charger DC output is: 5V/3A, 9V/23A, 12V/67A, 10V/25A. Therefore, these two different models of chargers, the parameters are also different.
3, MDY-08-EV and MDY-11-EM are two different charger models. For example, the original charger of the MDY-08-EV has a DC output of 5V/2A, while the DC output of the MDY-11-EM charger includes 5V/3A, 9V/23A, 12V/67A, and 10V/25A and other parameters. Therefore, the two models of chargers are different in terms of parameters. The above information is for reference only.
Electric vehicle wireless charging technology has become a popular electric vehicle to become the mainstream, the problem of battery life has not stopped, in order to solve the battery life problem, the various car companies are also trying their best to find a way to solve this problem, in addition to change the power and fast charge, in fact, there is a different way, that is, road charging, so that the steamThe car was running along the road.
The logic behind the wireless charging technology applied by Germany's WIFERION, which Tesla acquired, in the modified Model 3 is electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
The wireless charging process will definitely heat up. As long as the temperature is not very high, no problem, you see if there is something around the block, because many times love to put some things on it.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 uses induction.
Lveco (IVECO) must be no stranger to everyone, as the world's leading commercial vehicle manufacturer, IvECO products cover light, medium and heavy models. The Stellantis Group was formed in 2019 by the merger of the 50 percent holdings of Peugeot Citroen Group (PSA) and Fiat Chrysler Group (FCA). The vehicles that successfully tested inductive charging were an Iveco electric bus and two Fiat FivesThis amazing technology is DWPT - Dynamic wireless power transmission.
Machine Letang 20W 3-in-1 wireless charging board appearance packaging box with hook for convenient display Wireless charging road analysis , front printed JOYROOM brand, charger name, use scenario and salePoint and other information wireless charging path analysis , you can wireless charge the Apple family bucket at the same time. The back is also printed with product usage scenarios and feature descriptions, and can also be charged with two iphones and Apple Watch at the same time. Box drawer design, tray on the top of the wireless charging board.
Prying with anything is a disaster, and it is most likely to put your hands together.
Mobile power supply and maximum wireless charging path analysis iPhone 12 Pro Max is the same weight, and close to the mobile phone will be tightly adsorbed together, even if suspended will not fall, visible adsorption force is very strong. In addition, in daily use, you can spread the foot when the "vertical wireless charging" use, charging while watching the use experience is also very good. Green magnetic wireless charging mobile power disassemble the body shell, the edge of the buckle package.
In fact, the size of Apple's two chargers is the same, but the shooting is a person alone to complete, unassisted at the same time to take into account the caliper and camera, the data will inevitably have a small difference. Apple A2244 and A1695 Both chargers are equipped with a single USB-C port on the top surface and are centered in design.
