Then, put outThere are several charging methods listed, slow charging, fast charging, wireless charging, power station change. The four kinds of high charging efficiency are fast charging pile (supercharging pile), which can obtain hundreds of kilometers of battery life in a short time; The most efficient mode, but the scope of application is limited, is the power station. These two efficient replenishment mainstream modes can not be replaced by wireless charging.
From the point of view of charging methods, it is mainly divided into static and dynamic wireless charging methods. As the name suggests, the former is the vehicle in a static state for charging; The latter is the charging of the vehicle during driving, which is the main development direction of wireless charging in the future. Adopt thisDynamic wireless charging mode, electric vehicles need to carry more batteries, you can charge while driving.
electromagnetic induction type. A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
On the new flagship Mi 10, there is a 30W wireless flash charge function, which increases the power of the minute, and there is a 10W fast wireless backcharge, which means that the Mi 10 can be charged for other mobile phones that need to be charged.

Samsung wireless charging mobile body for aluminum alloy material, the entire body is elliptical cylinder, surface sandblasting treatment, feel good. Samsung wireless charging mobile powerSupport AFC, QC fast charge output, Samsung mobile phone users can get a very good charging experience when using. For QC fast charging equipment, the compatibility is not good.
Speaking of Nanfu battery, it can be said that it is a household name, and the advertising slogan of "one section is stronger than six sections" has been deeply rooted in people's hearts. The company, which was founded in the 1980s, has gone through more than 30 years and has now become a leading enterprise in the domestic alkaline zinc-manganese battery industry. With more than 100 patents on just one small battery, it is a miracle.
Full Gla wireless charging pile is a false advertising scam.The scam, which often appears on social media and some shopping websites, sells high-end and stylish wireless chargers at a low price, claiming that the charger can be easily charged wirelessly, has a large battery capacity and supports multiple device charging.
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. And more importantly, if the ministryThe dynamic wireless charging mode 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.
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.
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 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.
Wireless charging of electric vehicles is very strange to consumers, it is like we look at the concept car is a future scene. But if it can be done, yesCan greatly alleviate the impact of inconvenient charging.
The race to build a universal wireless charging technology is in full swing. New and exciting advances in wireless charging technology and products continue to emerge - some companies are focused on one technology, while others 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.
Compared with the traditional wired charging method, wireless charging has become a new technology with the advantages of no charger connection, voltage stability, surge prevention and so onThe important development direction of electric vehicle 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.
